(Fuselage stations and water lines are fixed reference points used by maintenance personnel to locate parts of the aircraft structure.)\n- If any rivets are missing in that area, those rivets must be installed before the aircraft is flown again.\n- The inspection must be carried out following the instructions in the Raytheon Mandatory Service Bulletin SB 53-3341 (Revision 1 or Revision 2) and the Bonanza Series Maintenance Manual.\n\n**Which aeroplanes are affected**\n\n- The AD lists two groups of serial-number ranges covering A36, B36TC, 36 and A36TC variants. The exact affected serial numbers are set out under the \"Applicability\" section of the AD.\n\n**When the work must be done (compliance times)**\n\n- For Group 1 aircraft: within 100 hours time-in-service after 22 March 2001.\n- For Group 2 aircraft: within 100 hours time-in-service after 20 March 2003, unless the inspection/repair has already been done.\n- If missing rivets are found, installation must be completed before further flight (i.e. the aircraft may not be flown until the rivets are installed).\n\n**Why the rule was issued (stated reason and technical effect)**\n\n- The manufacturer identified instances of missing rivets in the specified fuselage area. The AD states these rivets are required so the fuselage can carry its ultimate load; without them there is a risk of critical structural failure and loss of control. The AD references a related FAA AD (FAA AD 2003-01-01) and relies on the manufacturer service bulletin for inspection/repair procedures.\n\n**Practical effects, incentives and costs**\n\n- Who pays: aircraft owners/operators pay for the inspection labour and any parts (rivets) and for any follow-up work.\n- Who decides and enforces: the Civil Aviation Safety Authority (CASA) delegate issued the AD and enforcement uses the Civil Aviation Regulations; the AD prescribes the method (service bulletin and maintenance manual) but compliance monitoring is carried out under CASA oversight and routine maintenance checks.\n- Behaviour change required: owners/operators must schedule and carry out the required inspection within the stated time window and must not operate an aircraft found to have missing rivets until the rivets are installed.\n- Compliance burden: the AD references a specific manufacturer service bulletin (SB 53-3341 Rev 1 or Rev 2) which contains the required inspection steps. This reduces ambiguity about how to comply but requires access to that bulletin and the maintenance manual. The AD imposes a short compliance window (100 hours time-in-service) which likely pushes operators to perform the work at the next available maintenance opportunity or sooner.\n- Trade-offs and opportunity cost: operators will either perform this work at a scheduled maintenance (minimising additional downtime) or incur unscheduled downtime to meet the AD. There is an immediate safety benefit (mitigating risk of structural failure) at the cost of time and money to inspect and install rivets where needed.\n- Implementation risks: the AD depends on correct identification of serial numbers and following the specified service bulletin. Mistakes in reading the applicability table or not using the correct revision of the bulletin could create compliance uncertainty. The AD also revokes the prior AD and replaces it with this amendment, so operators must ensure they are following the current wording and compliance dates.\n\n**Source claim and brief testing against costs and incentives**\n\n- The AD's stated purpose is to address a structural safety risk from missing rivets (Background). That purpose is operationalised by a narrow, prescriptive inspection and repair requirement tied to a manufacturer service bulletin (Requirement; Accomplishment Instructions). The immediate cost of compliance falls on aircraft owners; the benefit (reduced risk of structural failure) accrues to operators, passengers and the public. The AD concentrates the burden on the specific affected fleet (those serial numbers listed) while the safety benefit is broader (accident prevention). The AD imposes a clear behavioural constraint (no further flight until rivets are installed if missing) with low ambiguity about acceptable repair methods (service bulletin/maintenance manual). The main implementation risk is ensuring the correct aircraft are identified and that service bulletin instructions are correctly followed.\n\n(References in the AD: \"Applicability\", \"Requirement\", \"Compliance\", and \"Background\" sections; it also notes FAA AD 2003-01-01.)"}},"importantCases":[],"_links":{"self":"/api/acts/ad-beech-36-48-amdt-1-right-hand-fuselage-rivets","history":"/api/acts/ad-beech-36-48-amdt-1-right-hand-fuselage-rivets/history","analysis":"/api/acts/ad-beech-36-48-amdt-1-right-hand-fuselage-rivets/analysis","conflicts":"/api/acts/ad-beech-36-48-amdt-1-right-hand-fuselage-rivets/conflicts","importantCases":"/api/acts/ad-beech-36-48-amdt-1-right-hand-fuselage-rivets/important-cases","documents":"/api/acts/ad-beech-36-48-amdt-1-right-hand-fuselage-rivets/documents"}}
