AD/BEECH 90/75 Amdt 5 - Nose Landing Gear Lower Shock Absorber Assembly

The Directive rests on a short set of concepts that convert a manufacturer service bulletin into mandatory regulatory action for a defined fleet segment.

Applicability and scope: the Directive applies to Model 65‑90, 65‑A90, B90, C90, and C90A serial numbers LJ‑1 through LJ‑1190; Model E90 serial numbers LW‑1 through LW‑347; and Model F90 serial numbers LA‑2 through LA‑236. Those serial number ranges define the set of aircraft to which the inspection and corrective requirements apply. Operators must check an aircraft’s model and serial number against these ranges to determine applicability.

Mandated inspection method: the inspection must be performed using either fluorescent liquid penetrant or magnetic particle methods, specifically as laid out in Part II of Raytheon MSB SB 32‑2102 Revision 7 (July 2003). The Directive therefore adopts by reference an external manufacturer procedure and fixes particular non‑destructive test (NDT) methods rather than leaving method choice to the maintenance organisation.

Conditional corrective action and terminating action: if cracks are found, incorporation of an indicated fork kit (Kit No. 101‑8030‑1S or 114‑8015‑1S, as applicable) is required and must be completed before further flight. The Directive states that incorporation of the kit is terminating action for the repeated inspection requirement; once the kit is fitted the repetitive inspections required by this Directive cease.

Repeat interval and initial timing: the repeat inspection interval is every 200 hours TIS or less. Initial inspection timing depends on prior compliance with earlier versions of the Directive: either within 200 hours TIS after the last inspection required by the prior issue, or within 200 hours after 5 July 2007 for aircraft not previously affected.

Document correction and external reference reliance: Amendment 5’s stated purpose is to correct an earlier textual error (Part III should have read Part II) that was inherited from the FAA AD. The Directive therefore depends on an accurate cross‑reference to the manufacturer’s MSB and acknowledges reliance on FAA material (FAA Corrected AD 2004‑23‑02 Amdt 39‑13857), signalling coordination between CASA and the FAA while anchoring regulatory requirements to external technical publications.

Operational constraint: the “before further flight” requirement for corrective action draws an operationally binding line: aircraft found with cracks cannot legally continue flying under this Directive until the kit is incorporated, imposing immediate maintenance and grounding considerations for operators.

The Directive explicitly affects owners and operators of Beechcraft Model 65‑90, 65‑A90, B90, C90, C90A, E90 and F90 aeroplanes with serial numbers in the ranges specified (LJ‑1 to LJ‑1190, LW‑1 to LW‑347, LA‑2 to LA‑236). Those individuals and organisations are required to comply with the inspections and corrective actions set out.

Maintenance organisations and approved NDT providers are directly affected because the inspection must be performed using fluorescent liquid penetrant or magnetic particle methods in accordance with Part II of Raytheon MSB SB 32‑2102 Revision 7 (July 2003). That imposes a requirement on the competence and equipment of whoever performs the inspection: maintenance providers must either have the capability to carry out the specified NDT techniques and follow the MSB procedures or outsource to a provider that does.

Aircraft operators who have previously complied with an earlier issue of this Directive are affected differently from those who have not. The compliance schedule distinguishes between aircraft “affected by the previous issue” and those “not affected by the previous issue,” with corresponding differences in initial inspection timing. Operators therefore need to determine their aircraft’s status under prior AD issues to calculate initial deadlines.

Parts suppliers and installers are affected because the Directive requires incorporation of specific kits (Kit No. 101‑8030‑1S or Kit No. 114‑8015‑1S) where cracks are found. Availability of those kits, the correct kit selection for a given model or serial range, and the capacity to install them according to the MSB determine lead times and operational downtime for affected aircraft.

Regulatory personnel at CASA (and, by reference, potentially the FAA) are affected as they are the issuing and coordinating authorities. The Directive is issued by CASA (signed by David Punshon, Delegate of CASA) and explicitly references FAA material, indicating a relationship between national regulatory action and foreign ADs and MSBs. Although the Directive text does not list enforcement mechanisms in detail, CASA’s issuance creates a regulatory obligation on the listed operators within Australian jurisdiction.

Finally, insurers and lessors may be materially affected because this Directive changes maintenance obligations, inspection schedules and the conditions under which an aircraft may legally fly (notably the “before further flight” requirement where cracks are found), all of which can affect operational availability, risk profile and contractual obligations between owners, operators and financiers.

Duties specified by the Directive are concrete and prescriptive. They fall into inspection, corrective action, timing, and recordation activities.

Inspection duty: Requirement 1 requires operators to “inspect, using fluorescent liquid penetrant or magnetic particle method, the nose landing gear fork assembly for cracks, in accordance with Part II of Raytheon Aircraft Company Mandatory Service Bulletin (MSB) SB 32‑2102 Revision 7, Revised: July 2003.” The duty is therefore to perform the inspection to the technical standard and procedure set out in the referenced Part II of the MSB. The choice of two named NDT methods restricts the acceptable inspection techniques.

Corrective action duty: Requirement 2 instructs that “If cracks are found during the Requirement 1 inspection, incorporate Kit No. 101‑8030‑1S or Kit No. 114‑8015‑1S, as applicable; as specified in MSB SB 32‑2102 Revision 7, Revised: July 2003.” The duty is to fit the specified kit in accordance with the MSB when a crack is detected. The Directive also states that incorporation of the kit is “terminating action for the inspection requirements of this Directive” (Note 1), creating an interaction between corrective action and ongoing obligations.

Repeat inspection duty: Requirement 3 requires repeating the inspection “in accordance with Part II of MSB SB 32‑2102 Revision 7” at intervals not to exceed 200 hours TIS. The compliance section restates the repeat interval as “At intervals not to exceed 200 hours time in service.” This creates a recurring maintenance obligation unless terminating action (kit incorporation) has been completed.

Timing duties: The Compliance provision prescribes when initial inspections must occur. For aircraft previously affected by an earlier issue of the Directive, the initial inspection must be done “within 200 hours time in service after the last inspection required by the previous issue of this Directive.” For aircraft that were not affected by the prior issue, the initial inspection must be done “within 200 hours time in service after 5 July 2007.” For cracks found, Requirement 2 must be satisfied “before further flight.” The Directive emphasises that “The compliance times for Requirements 2 and 3 remain unchanged by this issue of the Directive,” indicating that earlier deadlines for corrective and repeat actions persist.

Rights and clarifications in the text are limited. The Directive grants one clear operational effect: incorporation of the specified kit is terminating action for the requirement to continue repetitive inspections. That creates a choice for operators: undertake ongoing repetitive inspections at 200‑hour intervals, or, upon detection of a crack, fit the kit and thereby cease the repetitive inspection requirement under this Directive.

The Directive also embeds rights in the sense of procedural correctness: it requires compliance “in accordance with” a named Part II of a named MSB. That means operators are entitled to rely on the technical procedures and acceptance criteria in that MSB when performing the mandated inspections and kits. Conversely, operators must ensure they are following the correct revision and part (SB 32‑2102 Revision 7, Part II), because Amendment 5 exists precisely to correct a prior mis‑reference to Part III.

The document does not grant any exemption or alternative procedure; it is prescriptive. It also does not set out appeals, waiver or extension processes; such mechanisms, if available, are not contained in the text supplied.

The Directive text supplied does not specify criminal, civil or administrative penalties, nor does it describe enforcement procedures or infringement notices. The AD records that it “becomes effective on 5 July 2007” and is signed by a CASA delegate (David Punshon, 9 May 2007). The Directive contains operationally binding requirements, notably that incorporation of a specified kit must be completed “before further flight” where cracks are found, and that inspections be carried out within set TIS windows. These stipulations create clear compliance obligations; however, the text does not detail the specific statutory enforcement mechanisms or penalty amounts that CASA may apply for non‑compliance in Australia.

Practically, the Directive’s “before further flight” requirement operates as an immediate operational restriction on aircraft found to have cracks, and thus enforces compliance by preventing continued operation until the required corrective action is taken. The Directive also fixes repeat inspection intervals and initial deadlines, which become part of the aircraft’s maintenance obligations.

Because the Directive does not itself spell out sanctions, readers should note the following source‑grounded facts: (1) this instrument is an Airworthiness Directive issued by CASA and therefore creates mandatory compliance obligations on the listed aircraft; (2) the text refers to and adopts by reference an external manufacturer MSB, which becomes the technical standard to be met; and (3) compliance timing and pre‑flight corrective obligations are explicit in the Directive. The text does not record whether CASA will use its regulatory powers under other statutes or regulations to enforce compliance, nor does it state the procedural route for seeking relief, extensions or alternative means of compliance. Those enforcement and penalty arrangements, if needed, would be found in CASA’s broader regulatory framework or other statutory instruments, which are not part of this Directive as supplied.

Operators should therefore treat the Directive’s requirements as mandatory and binding in practice and ensure actions are recorded and verifiable. The Directive itself imposes “before further flight” grounding where cracks exist; beyond that, readers must consult CASA’s enforcement policies and relevant aviation safety legislation for explicit penalty and enforcement mechanisms, because they are not set out in this AD.

The Directive explicitly cross‑references and relies upon external documents and related regulatory action. The primary interaction is with the Raytheon Aircraft Company Mandatory Service Bulletin (MSB) SB 32‑2102 Revision 7, Revised: July 2003, which the Directive makes mandatory by requiring inspections and kit incorporation “in accordance with Part II” of that MSB. This creates an interaction whereby the manufacturer’s technical procedures and repair instructions become normative for regulatory compliance. The Directive therefore imports the MSB’s technical standards into the regulatory obligation, and operators must follow that MSB Part II rather than inventing or substituting different inspection procedures.

The Directive also records a relationship with a related FAA AD: Note 2 states “FAA Corrected AD 2004‑23‑02 Amdt 39‑13857 refers.” Amendment 5 was issued to correct an error in Requirements 3, where “Part III of the referenced Beech MSB should have been Part II. This error flowed from related FAA AD 2004‑23‑02.” The text therefore documents that the CASA Directive has been influenced by the FAA AD and that the correction aligns the CASA requirement with the correct MSB part. This shows inter‑jurisdictional interplay: CASA’s AD references and adjusts for a related FAA action.

Amendment history in the Directive also records prior regulatory interactions: Amendment 3 introduced a modification kit which, if fitted, removed the repetitive inspection requirement. Amendment 4 required the same inspection requirements by a different inspection method and required incorporation of an improved nose landing gear fork kit anytime a crack is found; it also extended applicability to additional aircraft. Those amendments demonstrate the Directive’s evolution in response to manufacturer changes and possibly to foreign ADs; they document how regulatory obligations may be updated to reflect technical fixes or expanded fleets.

The Directive’s prescriptive reference to specific kit numbers and the MSB means it interacts with commercial contract law and supply obligations: incorporation of kit parts will require procurement and installation under maintenance contracts, and the MSB’s instructions will form the technical specification for repair work. Financially, the cost of inspections and kit installation will fall on aircraft owners/operators, and any lease or insurance arrangements will need to account for the Directive’s inspection and grounding contingencies.

The Directive does not provide alternative means of compliance or describe processes for exemptions or relief within the text provided. Therefore, any statutory flexibility (for instance, applications for extensions or alternate methods accepted by CASA) would need to be sought in CASA’s wider regulatory processes or other relevant aviation law instruments, which are not set out in this Directive.

The Directive text itself records a compact amendment narrative focused on remedies and correction of a drafting error.

• Amendment 3: According to the Directive’s Background, Amendment 3 introduced a modification kit which, if fitted, removed the repetitive inspection requirement. That amendment therefore created a path to terminate the ongoing inspection obligation by installing a specific modification. The Directive’s Note 1 echoes that incorporation of Kit No. 101‑8030‑1S or Kit No. 114‑8015‑1S is terminating action for the inspection requirements of this Directive, reflecting that earlier Amendment 3 established the terminating‑action concept.

• Amendment 4: The Background records that Amendment 4 required “the same inspection requirements by a different inspection method,” required incorporation of an improved nose landing gear fork kit anytime a crack is found, and added additional aircraft to the applicability. That suggests Amendment 4 altered the technical inspection method and expanded the set of affected serial numbers. The Directive does not reproduce the full text of Amendment 4 but summarises its substantive outcomes: different inspection method, mandatory kit on detection of cracks, and wider applicability.

• Amendment 5: The present instrument is Amendment 5. Its explicit purpose is to correct an error in Requirements 3 of the previous issue, where Part III of the referenced Beech MSB should have been Part II. The Background states that this error flowed from the related FAA AD 2004‑23‑02. Amendment 5 thus performs a textual correction aligning the Directive with the correct Part II of MSB SB 32‑2102 Revision 7 (July 2003). This correction is important because the specified inspection procedures are in Part II; mis‑referencing Part III would have required a different set of procedures.

The Directive’s effective date is recorded: “This Airworthiness Directive becomes effective on 5 July 2007.” It is signed by David Punshon, Delegate of CASA, on 9 May 2007. The Compliance section of the Directive also notes that “The compliance times for Requirements 2 and 3 remain unchanged by this issue of the Directive,” signalling that Amendment 5 makes a correction without altering the substantive timing of corrective or repeat inspections established earlier.

No other amendment dates, issue numbers, or full earlier texts are included in the supplied material. The summary in the Background is the source’s own account of the prior amendments’ effects and the reason for Amendment 5.

The supplied Directive contains no litigation history. It names no judicial or administrative decisions, and no court or tribunal proceedings are referenced in the text. The document’s Background and notes discuss prior Amendments and the relationship to an FAA AD, but they do not record any legal challenges, appeals, or court findings concerning the Directive or its predecessors.

Therefore, based strictly on the material provided, there is no recorded litigation arising from this Directive or its earlier amendments in the text. Practitioners seeking precedent or dispute outcomes related to this AD will need to consult external legal databases or CASA records; those sources are not part of the Directive itself and are not quoted in the supplied material.

Several practical pitfalls and points of potential confusion are apparent from the Directive text; these are items that readers should verify against the source documents and their own maintenance records.

1. Correct MSB part: Amendment 5 corrects a prior mis‑reference from Part III to Part II of Raytheon MSB SB 32‑2102 Revision 7. Reliance on the wrong MSB part would mean performing an incorrect inspection method or applying the wrong acceptance criteria. The Directive requires the inspection “in accordance with Part II” (Requirement 1). Operators must ensure they use Revision 7, Part II of SB 32‑2102 (Revised: July 2003), not Part III.

2. NDT method specificity: The Directive requires either fluorescent liquid penetrant or magnetic particle methods. These are specialised NDT methods that require equipment, materials, and trained technicians. Using a different NDT technique that is not authorised in Part II of the MSB would not satisfy the Directive. Maintenance organisations must verify competence and qualification before accepting or performing the inspection.

3. Serial number boundaries and applicability: The aircraft applicability is limited to precise serial number ranges (LJ‑1 through LJ‑1190; LW‑1 through LW‑347; LA‑2 through LA‑236). Operators must confirm serial numbers precisely; a typo or misread plate could lead to incorrect application or failure to apply the AD when required. Amendment 4 reportedly added additional aircraft to applicability; operators should verify whether a given serial number was included by that Amendment or earlier issues.

4. Differing initial compliance timing: The initial inspection window depends on whether the aircraft was “affected by the previous issue of this Directive.” That status is a factual question and may be unclear in some maintenance records. Operators must determine whether the aircraft was subject to the prior AD issue and calculate the initial 200‑hour TIS deadline accordingly. Misclassification could lead to missed initial inspection windows.

5. “Before further flight” requirement: Where cracks are found, incorporation of the designated kit must be done before further flight. That imposes immediate operational consequences and potential unscheduled grounding. Parts availability, installer availability, and access to the MSB instructions will determine how long the aircraft is out of service.

6. Kit selection mistakes: Two kit numbers are authorised: 101‑8030‑1S and 114‑8015‑1S, “as applicable.” The Directive does not in the text expand on which kit is applicable to which models or serial ranges; that determination is delegated to the MSB. Selecting the wrong kit could fail to meet the Directive’s terminating action condition. Operators must use the MSB to determine which kit applies to a specific aircraft.

7. Repetitive inspection termination: Incorporation of the kit is terminating action for the inspection requirements of this Directive (Note 1). However, operators should verify whether other regulatory requirements or other ADs still require inspections after kit installation; termination here only applies to this particular Directive.

8. Reliance on external documents: The Directive imports technical content by reference (MSB SB 32‑2102 Rev 7). If the MSB has subsequent revisions or corrections, or if the operator does not have access to the exact revision referenced, ambiguity may arise. The Directive’s correction to Part II highlights the importance of using the exact referenced revision.

9. No penalties detailed: The AD does not spell out enforcement mechanisms or penalties in the text provided. Operators must not assume absence of enforcement; the Directive creates mandatory obligations, and enforcement may be taken under broader aviation safety laws which are not reproduced in this instrument.

10. Record keeping and proof of compliance: The Directive does not state the recordkeeping format or retention period. Operators should ensure maintenance logs capture the inspection method, MSB revision and part, findings, kit serial/part numbers installed, and dates, so compliance can be demonstrated to CASA on demand.

A stepwise, source‑grounded compliance checklist based on the Directive text:

1. Determine applicability:

   • Confirm aircraft model and serial number against the Directive’s applicability lists: Model 65‑90, 65‑A90, B90, C90, C90A serial LJ‑1 to LJ‑1190; Model E90 serial LW‑1 to LW‑347; Model F90 serial LA‑2 to LA‑236. If the aircraft’s serial number is within these ranges, the Directive applies.

2. Establish prior AD status:

   • Determine whether the aircraft was “affected by the previous issue of this Directive.” If it was, compute the initial inspection deadline as “within 200 hours TIS after the last inspection required by the previous issue.” If it was not, compute the initial inspection deadline as “within 200 hours TIS after 5 July 2007.” Document how this determination was made.

3. Obtain the correct MSB:

   • Obtain Raytheon Aircraft Company MSB SB 32‑2102 Revision 7, Revised: July 2003, and specifically Part II. The Directive requires inspections and corrective action “in accordance with Part II of” that MSB. Ensure you have the correct revision and part; Amendment 5 corrects a prior mis‑reference to Part III.

4. Schedule and perform the inspection:

   • Arrange for the inspection to be performed by personnel qualified in fluorescent liquid penetrant or magnetic particle NDT as specified. Perform the inspection in accordance with Part II of the MSB. Record the inspection method used, the MSB part/revision cited, date, technician identity/qualification, and findings.

5. If cracks are found:

   • Do not return the aircraft to flight until corrective action is taken. Requirement 2 states that where cracks are found, incorporate Kit No. 101‑8030‑1S or Kit No. 114‑8015‑1S “as applicable” in accordance with the MSB. Obtain and order the applicable kit, confirm correct kit for the aircraft, and install per MSB instructions.
   • After kit incorporation, record the kit part number, kit serial/identifiers (if any), installation date, installer details and reference the MSB instructions followed.
   • Note that incorporation of the kit is terminating action for the inspection requirements of this Directive; once installed as required, you may cease the repetitive inspections required by this AD (but verify there are no other ADs or manufacturer requirements that continue to apply).

6. If no cracks are found:

   • Repeat the inspection at intervals not to exceed 200 hours TIS, as specified in Requirement 3 and the Compliance section (“At intervals not to exceed 200 hours time in service”). Each inspection must again follow Part II of the MSB and be documented.

7. Recordkeeping and evidence:

   • Maintain clear maintenance records demonstrating compliance with the inspection schedule, the MSB edition and part used, NDT method employed, findings, and any kits installed. Because the Directive does not specify recordkeeping procedures, retain sufficient detail to demonstrate compliance to CASA upon request.

8. Logistics and planning:

   • Anticipate potential grounding when cracks are found because kit incorporation must be completed “before further flight.” Plan for lead times to source the correct kit and for maintenance facility availability. Ensure the maintenance organisation is competent in both NDT and kit installation per the MSB.

9. Liaise with regulator if necessary:

   • If there is uncertainty about applicability, compliance times, or MSB instructions, consult CASA or refer to formal CASA guidance. The Directive does not include an alternate means of compliance or waiver process; any relief or alternative arrangements should be sought through official CASA channels.

10. Cross‑check with other obligations:

• Verify whether kit installation or the termination of inspections under this AD affects compliance with other ADs or manufacturer recommendations. The Directive states termination only for this Directive’s inspection requirements; it does not state that other obligations are removed.

Following these steps will satisfy the source‑specified requirements: use the specified NDT method per Part II of MSB SB 32‑2102 Rev 7; meet initial timing windows tied to prior AD status; complete kit incorporation before further flight where cracks exist; and repeat inspections every 200 hours TIS until terminating action is taken. Record each action carefully to demonstrate compliance with the Directive issued by CASA on 5 July 2007.
