AD/BEECH 35/74 Amdt 1 - Forward Elevator Cable

Several concepts central to the AD require precise understanding. Forward elevator control cable assembly refers to the specific cable run that connects the forward end of the elevator control system (likely the control column) to the aft bellcrank or cable system, as depicted in Figure 1. The figure is adapted from the Beechcraft Illustrated Parts Catalogue and provides a visual reference to identify the applicable part and routing. An operator must compare the actual cable installation on the aircraft with the figure; if it matches, the AD applies. Maintenance release period is the interval between scheduled maintenance releases under the aircraft’s approved continuing airworthiness management system. The AD provides a compliance grace period only for aircraft that have had the cable replaced or inspected within the last such period. For all others, compliance is required before further flight from 16 January 2012 (original issue) or, if the aircraft was not previously subject, from 27 February 2012. Positioning flight is a single flight with a pilot only, permitted only when the aircraft is located where the inspection cannot be carried out. This concept balances safety risk (the cable could fail) against the economic necessity of moving the aircraft to a suitable maintenance facility. The AD does not define where a “place where the inspection can be carried out” may be, but it implies a workshop with appropriate tools, access to the Beechcraft data or FAA AC, and likely a licensed aircraft maintenance engineer. Instructions for Continuing Airworthiness (ICA) are technical procedures published by the type certificate holder (now likely Textron Aviation) that detail how to inspect and maintain the elevator cable system. CASA removed the original prescriptive requirements (repeat inspections and 15-year mandatory removal) because it considers the ICA “satisfactory to ensure the failure of the elevator cable does not occur provided that the ICA is adhered to during the inspection process.” This is a form of regulatory delegation: the state relies on a private manufacturer’s technical data rather than a one-size-fits-all AD requirement. However, ICA may be updated independently, and an operator must keep pace. FAA Advisory Circular 43-13-1B is an accepted guidance document for inspection methods; chapter 7, section 8, paragraph 7-149(d) describes procedures for inspecting control cables. The AD accepts this as an optional means of compliance, but the operator is still responsible for ensuring the inspection meets the standard described. Removal from service means the defective cable must be physically taken off the aircraft and not reinstalled; the AD explicitly prohibits installing any such cable on any aircraft, even if later repaired. This is a strict prohibition with no exceptions. The effective date of this amendment is 27 February 2012, and it supersedes the original AD for all aircraft on or after that date. The original AD remains in effect only for actions taken before that date (those actions are deemed compliant). For aircraft that had not acted by 27 February 2012, the amended requirements apply from that date, but with the benefit of the positioning flight allowance and the revised applicability scope.

The AD directly imposes obligations on the registered operator of any Beechcraft 35 (Bonanza) series aeroplane fitted with the forward elevator control cable configuration shown in Figure 1. The operator is typically the person or company whose name appears on the aircraft’s certificate of registration. In practice, however, the compliance burden often falls on private owners who manage maintenance themselves, corporate flight departments, and maintenance organisations contracted to perform inspections. Because the AD requires actions “before further flight”, the operator must ensure that either the inspection or replacement is completed before the aircraft is flown again, unless a positioning flight is justified. Pilots are also affected: if they are aware that the AD has not been complied with, they must not fly the aircraft (unless the positioning flight exception applies). The positioning flight privilege restricts the pilot to being the only person on board; passengers, cargo, or additional crew cannot be carried. This affects charter operations, flying schools, and clubs if they operate impacted Bonanzas. Maintenance engineers and approved maintenance organisations (AMOs) are affected because they must have the technical capability to perform the inspection in accordance with FAA AC 43-13-1B or Beechcraft maintenance data, and to remove and replace cable assemblies. The AD does not prescribe a specific certification level, but general regulatory requirements under Part 43 of CASR apply: maintenance must be carried out by persons authorised under the regulations. Aircraft resellers and insurers may also be indirectly affected: a non-compliant aircraft cannot be flown and may lose airworthiness certification, affecting its value and insurability. CASA is the regulator that issues, enforces, and withdraws ADs; CASA delegates (such as the signatory Peter Boyd) are named on the instrument. The AD also affects manufacturers (Beechcraft, now Textron Aviation) because CASA relied on the manufacturer’s ICA to remove prescriptive requirements; the manufacturer thus acquires an ongoing duty to maintain and supply accurate ICA, although legal liability for failure would stem from contract or tort, not the AD itself. The scope of affected aircraft is narrowed by Figure 1: only those with the specific forward cable configuration are caught. Operators of Bonanza 35 series aeroplanes with a different cable arrangement (e.g., later production or modified) may be outside the AD, but they must confirm this by reference to the parts catalogue and physical inspection. The AD does not affect other Bonanza series variants not fitted with that cable, but the original AD applied to all Beechcraft 35 aeroplanes indiscriminately before this amendment. This amendment thus reduces the population of aircraft to which the AD applies, benefiting owners of aircraft with non-standard cable runs. There is no exception for experimental, amateur-built, or ex-military aircraft if they are registered and operated under the Bonanza type certificate. The compliance costs are borne entirely by these operators and maintenance providers, with no direct government subsidy. The AD’s removal of repeat inspections may reduce the recurrent cost for operators who have already done the initial action, but introduces a new ongoing burden to stay abreast of ICA updates, which may impose costs through additional training or procedural changes.

Duty 1: Before further flight (subject to the timing rules), the operator must inspect the forward elevator cable assembly for wear, broken wires and corrosion in accordance with FAA AC 43-13-1B, chapter 7, section 8, paragraph 7-149(d) or Beechcraft maintenance data, or replace the cable assembly. For aircraft not previously inspected or replaced within the last maintenance release period, this duty arose from the original AD’s effective date of 16 January 2012; for aircraft that had already taken that action before this amendment, the duty is already satisfied. For aircraft falling within the new applicability (Figure 1) that had not yet complied, the duty is now effective from 27 February 2012. Duty 2: If the inspection reveals a defect (wear, broken wires, corrosion that renders the cable unserviceable), the operator must remove the defective cable from service before further flight. Duty 3: No person may install on any aircraft a cable assembly or part that has been removed under requirement 2 of this AD. This is a strict prohibition; there is no exception for repair or recertification. Duty 4: The operator must ensure that any positioning flight (where the inspection cannot be carried out at the aircraft’s current location) conforms to the restriction: one flight, pilot only, to a place where the inspection can be performed. The operator must determine that such a flight is reasonably safe; the AD does not absolve the operator from the duty to maintain the aircraft in an airworthy condition, but it creates a narrow exception to the “before further flight” requirement for that single transit.

Rights: The operator has the right to rely on the FAA AC 43-13-1B or Beechcraft maintenance data as an acceptable means of compliance for the inspection. The operator is not required to seek prior CASA approval of the method if it falls within those documents. The operator also has the right to choose between inspection and replacement. If the operator chooses replacement, the duty to inspect is extinguished for that cable. The operator has the right to a positioning flight if the aircraft is located where the inspection cannot be performed, but this right is conditional on the pilot being the only person on board and the flight being directly to the inspection location. The operator has the right to treat any previous inspection or replacement done under the original AD as satisfying requirement 1, avoiding a second action. Operators who maintain their aircraft in accordance with the manufacturer’s ICA also have the right to rely on those procedures for ongoing airworthiness without recurrent AD mandates. This right, however, is not absolute: if ICA are not followed, the operator may be in breach of other regulatory obligations (e.g., CAR 1988 regulations on maintenance), even if not in breach of this specific AD. The operator has the right to seek a variation or alternative means of compliance from CASA under the Civil Aviation Act, but the AD does not mention that process; it is an external regulatory right. The AD does not grant a right to compensation for the cost of compliance. The operator also has the right to be informed of the applicability via Figure 1, which reduces the risk of being wrongly caught by a vague applicability clause. Finally, the operator has the right to record compliance in the maintenance release or logbook and have that record accepted by CASA as evidence of compliance.

The AD itself does not set out penalties; it is a legislative instrument made under the Civil Aviation Act 1988 and the Civil Aviation Regulations (CAR) or Civil Aviation Safety Regulations (CASR). Non-compliance with an airworthiness directive is a breach of the general airworthiness obligations. Under CAR 1988, regulation 42ZC (in effect at the time) made it an offence to operate an aircraft that does not comply with an airworthiness directive. The maximum penalty was typically 50 penalty units for an individual and 250 for a body corporate (a penalty unit was $110 at the time, so $5,500 and $27,500 respectively). Under CASR Part 91 (which later superseded some provisions), operating an aircraft that is not in compliance with an airworthiness directive is an offence with similar penalty levels. In addition, CASA may take administrative enforcement actions: issuing a direction to ground the aircraft, varying or suspending the aircraft’s airworthiness certificate or registration, or requiring it to be made compliant before further flight. These administrative actions are often more costly to the operator than a fine because grounding prevents revenue generation. The AD’s requirement to act “before further flight” means that flying a non-compliant aircraft is a strict liability offence in many cases: the prosecution need not prove intent, only that the aircraft was operated while the AD was not complied with. The fact that the operator was unaware of the AD or misinterpreted Figure 1 is not a defence under strict liability, though it may go to penalty mitigation. CASA enforcement officers may perform ramp checks and inspect maintenance records. If a deficiency is found, a verbal or written direction may be issued. Repeated or deliberate non-compliance could lead to criminal prosecution under the Crimes Act 1914 (Cth) for conspiracy to defraud or making false statements (if records are falsified). CASA may also refer matters to the Director of Public Prosecutions. The AD’s removal of repeat inspections reduces the number of potential compliance points, but the ongoing obligation to follow ICA creates an area where non-compliance could be harder to detect (since there is no explicit AD requirement to produce ICA compliance evidence). An operator might argue that ICA are advisory, but the AD’s background says they are “considered satisfactory to ensure failure does not occur provided that the ICA is adhered to.” A court could infer that an operator who does not follow ICA after this amendment is not maintaining airworthiness, and thus breaches the general duty under CAR 42ZC or CASR 91.055. Enforcement actions may also target maintenance organisations that perform substandard inspections or fail to remove defective cables. If a cable fails and causes an accident, the operator and maintenance organisation could face criminal charges for reckless conduct or manslaughter (if fatalities result), in addition to civil liability. The AD’s explicit prohibition on reinstalling removed cables is a bright-line rule; any violation of that prohibition would almost certainly be treated as a serious breach. The positioning flight allowance is conditional; if a positioning flight is made without a valid basis (e.g., the inspection could have been performed locally), the operator may be in breach of the requirement to act before further flight, even though a flight occurred. Enforcement thus involves both administrative and criminal dimensions.

The AD sits within a hierarchy of Australian aviation law. The primary authorising legislation is the Civil Aviation Act 1988, which confers on CASA the power to issue airworthiness directives under its general power to ensure the safety of air navigation. The AD is a legislative instrument under the Acts Interpretation Act 1901 and must be registered on the Federal Register of Legislation (FRL). It interacts with the Civil Aviation Regulations 1988 (CAR) and the Civil Aviation Safety Regulations 1998 (CASR). Specifically, CAR 1988 regulation 42ZC required that “an aircraft shall not be operated unless it complies with each airworthiness directive applicable to the aircraft”. This provision was later replaced by CASR Part 91, but during the AD’s effective period, CAR 42ZC was in force. The AD also interacts with Part 43 of CASR, which governs maintenance standards. The inspection methods referenced (FAA AC 43-13-1B and Beechcraft maintenance data) are accepted as means of compliance, but Part 43 still requires that the person performing the inspection be authorised under the regulations (e.g., an LAME or AMO). The AD does not override Part 43; it supplements it. The AD also interacts with the International Civil Aviation Organization (ICAO) standards, since Australia is a signatory to the Chicago Convention. An AD is a means of continuing airworthiness that must be accepted by other ICAO states for aircraft registered in Australia. Conversely, FAA ADs on the same subject (if any) are not automatically binding in Australia, but CASA may adopt them; here CASA references FAA AC but not an FAA AD. The AD’s acceptance of FAA AC as a means of compliance creates a cross-jurisdictional legal link: an Australian operator who complies with FAA guidance is deemed compliant, even though that guidance is not a regulatory instrument under Australian law. This reduces friction for operators who also fly to the US. The AD interacts with the manufacturer’s Instructions for Continuing Airworthiness (ICA). While the AD does not mandate compliance with ICA (it only removes the prescriptive AD requirements because ICA exist), the manufacturer’s ICA may be incorporated by reference into the aircraft’s type certificate data sheet or maintenance manual, which in turn is required to be followed under CASR. Therefore, an operator who disregards ICA may be violating the maintenance manual requirement even if not violating the AD. The AD also interacts with the aircraft’s certificate of airworthiness (CofA). An aircraft that does not comply with an AD is not airworthy, and its CofA is effectively void until compliance is restored. This interaction means insurers may refuse coverage, and any flight undertaken may be in breach of the aircraft’s operating limitations. The AD also interacts with state and territory work health and safety laws if the aircraft is used for commercial operations; but generally Commonwealth law ousts state law in aviation safety. The AD does not interact with the Competition and Consumer Act 2010 directly, but a failure to comply could be used as evidence in a product liability claim against the manufacturer or maintenance provider. Additionally, the AD’s removal of the 15-year mandatory replacement shifts the burden of determining cable life from a prescriptive rule to an engineering judgment under ICA; this may interact with the operator’s common law duty of care to passengers and third parties. The positioning flight allowance interacts with the flight crew licensing rules (Part 61 of CASR): only a pilot may be on board, meaning no other crew members, which could affect multi-pilot operations if the aircraft requires a second pilot for certification. The AD does not address that, so the operator must ensure the flight is conducted under the appropriate pilot licence and aircraft certification limitations.

The original AD/BEECH 35/74 was issued with an effective date of 16 January 2012. That original issue required immediate inspection or replacement of the forward elevator cable before further flight, repeated inspections of the entire elevator control system, and mandatory removal of cables that had been in service for more than 15 years. The background notes that CASA had received reports of a cable failure and five unserviceable cables, prompting the urgent action. The original issue did not include Figure 1; its applicability simply read “All Beechcraft 35 (Bonanza) aeroplanes”. This was broad and potentially caught aircraft whose cable configuration might not be susceptible to the reported failure mode. The original issue also prohibited positioning flights; inspection was required before any flight. Amendment 1, effective 27 February 2012, made four principal changes. First, it introduced Figure 1 to restrict applicability to aeroplanes fitted with the specific forward elevator control cable configuration shown. This narrowed the population of affected aircraft, reducing compliance costs for operators whose cable routing differed. Second, it removed the requirements for repeat inspections of the entire elevator control system and for mandatory removal of cables over 15 years old. This was based on CASA’s judgment that the manufacturer’s Instructions for Continuing Airworthiness (ICA) provided satisfactory assurance against cable failure if adhered to during inspections. Third, it added a provision allowing one positioning flight (pilot only) to a place where the inspection could be carried out, for aircraft located where inspection was not possible. Fourth, it clarified that aircraft that had already replaced or inspected the cable under the original AD were considered compliant with requirement 1, thereby validating earlier actions. The amendment was signed by Peter Boyd, a delegate of CASA, on 23 February 2012. The AD notes that it “becomes effective on 27 February 2012.” The amendment was issued as AD/BEECH 35/74 Amdt 1 and published as Airworthiness Directive 4/2012. No further amendments are indicated in the source, and the source does not mention any subsequent amendments up to the date of the document (presumably 2012). The amendment was prompted by the publication of the manufacturer’s ICA, which CASA deemed adequate. The removal of prescriptive requirements signalled a shift from rule-based to performance-based regulation: instead of fixed intervals and age limits, CASA trusts the operator and the manufacturer to manage the safety case through documentation. This reduces the regulatory burden on operators who follow the ICA but may increase liability exposure if ICA are not properly implemented. The amendment also responded to the operational reality that some aircraft could not be inspected at their current location, introducing a commercially sensible solution. However, the amendment did not alter the prohibition on reinstalling removed cables, leaving that bright-line rule unchanged. No explanatory memorandum or regulation impact statement is provided in the source, so it is impossible to quantify the cost savings or additional risk associated with the amendment, but the removal of repeat inspections likely reduced compliance costs for operators over the lifecycle of the aircraft, while placing a premium on good record-keeping and adherence to the manufacturer’s documentation.

The source text does not name any court cases or administrative proceedings relating to this AD. Airworthiness directives are rarely directly litigated in Australian courts; they are legislative instruments that can be challenged under the Administrative Decisions (Judicial Review) Act 1977 (ADJR Act) or through an appeal to the Administrative Appeals Tribunal (AAT) for a review of a CASA decision, but only if a decision is made under the AD (e.g., a refusal to grant an alternative means of compliance or an enforcement action). The AD itself is a legislative instrument of a general nature, not a decision reviewable on its merits. An aggrieved operator could seek judicial review in the Federal Court on grounds such as procedural error, lack of power, or unreasonableness. However, the source does not indicate that any such application was made. The AD was issued under the powers of CASA’s delegate, and the background suggests it was motivated by factual reports of cable failures, so a legal challenge on the basis of insufficient evidence would face a high threshold. The absence of litigation history may indicate that the AD was accepted by the affected community without dispute, perhaps because the safety issue was real and the compliance cost was manageable. Alternatively, litigation may have occurred but is not referenced in the AD itself (which is a short regulatory document). In the broader context, Australian airworthiness directives have occasionally been the subject of AAT review when CASA refuses to grant an exemption or alternative compliance method (e.g., Re Gurgel and CASA (2004) AATA 678), but no such case is identified for this AD. The AD’s amendment removed several prescriptive requirements, which would likely reduce the potential for disputes: operators obtained the benefit of a narrower applicability and a relaxation of the recurring inspection mandate, making the AD less onerous than its predecessor. If litigation existed, it would more likely concern enforcement actions for non-compliance: CASA may have taken action against an operator who flew without inspection, and the operator might defend on the basis that the cable configuration did not match Figure 1, or that a positioning flight was improperly denied. But again, the source does not mention such cases. The fact that the AD emphasises using FAA AC 43-13-1B or Beechcraft data as an acceptable means of compliance could lead to disputes if a maintenance organisation used a different method that later failed; but that would be a contract or professional negligence dispute, not a direct challenge to the AD. In sum, there is no litigation history provided, and none can be legitimately inferred. The analyst must not invent cases.

Several traps await the unwary operator. First, the applicability depends on Figure 1, which is not self-explanatory. An operator must compare the actual cable installation to the figure. The figure is a black-and-white line drawing adapted from the Beechcraft Illustrated Parts Catalogue; without the original part number or a clear view of the routing, an operator might misidentify the configuration and either wrongly apply the AD (incurring unnecessary cost) or wrongly conclude the AD does not apply (risking enforcement and safety). The AD does not specify how to obtain the original parts catalogue; the operator must have it or consult a knowledgeable engineer. Second, the compliance timeline contains a subtle trap: for aircraft that have not had the cable replaced or inspected within the last maintenance release period, the original AD required action before further flight after 16 January 2012. This amendment restates that requirement but does not extend the deadline for those aircraft that were already delinquent. An aircraft that was due for compliance in January 2012 and did not act remains in breach even after the amendment comes into force, unless it now complies. The amendment’s statement that aircraft “that have had the forward elevator cable assembly replaced or inspected in accordance with the original issue of this AD are considered to be in compliance” implies that aircraft that should have complied but did not are still non-compliant. Third, the removal of repeat inspections and the 15-year mandatory replacement is not a licence to ignore the elevator cable for the life of the aircraft. The AD’s background says the manufacturer’s ICA “are considered satisfactory to ensure the failure of the elevator cable does not occur provided that the ICA is adhered to during the inspection process.” If the operator does not adhere to the ICA, the aircraft may be unairworthy under the general law, even though no specific AD requirement exists. This is a shift from prescriptive to performance-based regulation, and operators who assume no further action is needed may be caught out. Fourth, the positioning flight allowance is narrower than it appears. It applies only when the inspection “cannot be carried out” at the aircraft’s location. The operator bears the onus of proving impossibility, not mere inconvenience. A flight to a maintenance base that is simply cheaper or more familiar will not qualify. Moreover, the flight must be with “pilot only”, so no passengers, cargo, or additional crew. If the aircraft requires two pilots for its certification (some older models might be operated under a multi-pilot requirement), a single-pilot positioning flight could be illegal even if the AD allows it; the AD does not override other regulatory restrictions. Fifth, the prohibition on reinstalling removed cable assemblies applies regardless of whether the cable could be repaired. If an operator removes a cable that is not defective (e.g., a proactive replacement), the old cable may not be installed on any aircraft, even if it passes inspection. This trap is easy to overlook: the AD says “do not install on any aircraft a cable assembly or parts thereof that have been removed in accordance with Requirement 2 of this AD.” Requirement 2 only applies to cables found defective. But reading the three requirements together, Requirement 1 allows the operator to replace the cable even if not defective. A cable removed under Requirement 1 (non-defective replacement) is not caught by the prohibition. However, if the operator later inspects a removed cable and finds it defective, it would fall under Requirement 2. The distinction matters for shops that might want to use a serviceable removed cable as a spare. Sixth, the AD does not mandate any record retention period beyond the standard maintenance release. An operator who loses records of compliance may struggle to prove compliance if audited years later, and may have to repeat the inspection. Seventh, the AD is silent on the applicability of alternative means of compliance (AMOC). It lists two acceptable means but does not say whether CASA will approve others. An operator who wants to use a different inspection method (e.g., eddy current) must seek CASA approval separately; relying on an unlisted method could be non-compliance. Eighth, the amendment’s effective date is 27 February 2012. Any cable removed or replaced between 16 January and 27 February 2012 under the original AD must be treated according to the original AD’s requirement: that cable cannot be reinstalled (original AD had same prohibition). But if a cable removed during that window was not defective, the original AD still prohibited its reinstallation? The original AD’s Requirement 2 was identical: “Remove from service any forward elevator control cable assembly found to be defective”. It did not prohibit reinstallation of non-defective cables. The amendment’s prohibition only applies to cables removed under Requirement 2 as amended. This subtle distinction may cause confusion. Ninth, the AD applies to “all Beechcraft 35 (Bonanza) aeroplanes fitted with the forward elevator control cable configuration as detailed in figure 1 of this AD.” But what about aeroplanes that have been modified with a different cable configuration after manufacture? If the modification is approved (e.g., via a supplemental type certificate), the aircraft may no longer be fitted with the figure 1 configuration and thus may not be subject to the AD. However, the operator must have documentation of the modification; otherwise CASA could treat the original configuration as still present. Tenth, the AD does not require notification to CASA of compliance; it only requires the action. If an operator fails to record compliance, they may be unable to prove it during a ramp check, leading to grounding even if the inspection was done.

Compliance with AD/BEECH 35/74 Amdt 1 involves a structured process that begins with determining applicability. Step 1: obtain a copy of the AD including Figure 1. Compare the forward elevator control cable installation on the aircraft with Figure 1. The figure is adapted from the Beechcraft Illustrated Parts Catalogue; the operator or a licensed aircraft maintenance engineer (LAME) should visually inspect the cable routing and part identification. If the installation does not match Figure 1, the AD does not apply, but the operator should document the reason and retain that record. If it matches, proceed. Step 2: review the aircraft’s maintenance records to determine whether the forward elevator cable assembly has been replaced or inspected in accordance with the original AD (effective 16 January 2012) within the last maintenance release period. If so, the aircraft is deemed compliant with Requirement 1; no further action is needed for the AD itself, but the operator must continue to adhere to the manufacturer’s Instructions for Continuing Airworthiness (ICA) for ongoing inspections. If the records do not show such compliance, proceed to Step 3. Step 3: decide whether to inspect the cable or replace it. Inspection must be performed in accordance with FAA AC 43-13-1B, chapter 7, section 8, paragraph 7-149(d) or Beechcraft maintenance data. The inspection must check for wear, broken wires, and corrosion. The person performing the inspection must be authorised under CASR Part 43 (typically a LAME or an AMO). Alternatively, replace the cable assembly with a new or serviceable approved part. Replacement automatically satisfies the inspection requirement. Step 4: if the inspection reveals a defect (any wear, broken wires, or corrosion that renders the cable unserviceable per the standards used), the defective cable must be removed from service before further flight. Do not repair the cable; removal is mandatory. Step 5: the removed defective cable must not be installed on any aircraft. It should be destroyed or rendered unusable to prevent future reuse. Non-defective cables removed as part of a proactive replacement are not subject to this prohibition, but prudent practice is to mark them clearly and not reuse them without full inspection equivalent to the AD. Step 6: record the compliance action in the aircraft’s maintenance release or logbook. The entry should specify the date, the AD number, whether inspection or replacement was performed, the result (defects found or none), and the identity of the person or organisation that performed the work. If a replacement was done, include the part number of the new cable. Step 7 (ongoing): after compliance, follow the manufacturer’s ICA for continuing airworthiness of the elevator control system. The AD removed the prescriptive repeat inspection and 15-year removal requirements, but the ICA will prescribe intervals or triggers for inspection. The operator must ensure that the ICA is accessible and that maintenance is scheduled accordingly. Failure to adhere to ICA may result in the aircraft becoming unairworthy even though no further AD action is required. Step 8 (special situation): if the aircraft is located at a place where the inspection cannot be carried out (e.g., remote airfield without appropriate tools or engineer), a positioning flight is allowed. The flight must be with only the pilot on board and must be directly to a place where the inspection can be performed. The operator should justify and document the reasons why inspection was impossible at the original location. The one positioning flight is permitted only once per aircraft for this AD; after that flight, the inspection or replacement must be completed before further flight. Step 9: ensure that any maintenance organisation used is aware of the AD and has the technical data (FAA AC or Beechcraft data) available. If the operator chooses to use a different means of compliance (e.g., an alternative non-destructive test method), they must first obtain CASA approval for an alternative means of compliance (AMOC). Step 10: retain all records indefinitely, or at least until the aircraft is permanently withdrawn from service. CASA may audit compliance years later. The absence of records may result in the aircraft being considered non-compliant, requiring repeat inspection. Given the narrow applicability (Figure 1), operators of multiple Bonanza 35 aircraft must evaluate each aircraft individually; a fleet-wide policy of performing the inspection on all aircraft may be simpler but could incur unnecessary cost on aircraft not subject to the AD. The most cost-effective approach is to verify applicability first, then act accordingly. The amendment’s removal of repetitive requirements reduces lifecycle cost for those who comply and maintain ICA adherence, but it also places a premium on good documentation and proactive maintenance management. Compliance costs include labour (typically 1-3 hours for inspection, plus possible cable replacement part cost, which as of 2012 might be several hundred dollars). The positioning flight privilege reduces the economic penalty of grounding at remote locations, but the pilot-only restriction may still cause scheduling losses.
