(Applicability; Requirement)\n- The action is: carry out the work described in British Aerospace Mandatory Service Bulletin 52-JM 7793. (Requirement)\n- The deadline for completing that work is before 30 April 1994. (Compliance)\n\nWho it applies to\n\n- All Jetstream Series 3100 and Series 3200 aircraft whose constructor (serial) numbers are up to and including 972. Operators of those aircraft must comply. (Applicability)\n\nWhy it exists (as stated in the instrument)\n\n- The AD cites reports of spurious indications from the door warning system. It targets the passenger/crew drawbolt installations and the door warning system microswitch rigging to address those reports. (Background)\n- The AD also cross-references a corresponding UK Civil Aviation Authority directive (UK CAA AD 010-08-93). (Note)\n\nWho pays and who decides\n\n- The aircraft operators or owners must pay for and arrange the work required by the service bulletin. The AD imposes the obligation; the Civil Aviation Safety Authority issues the directive under the Civil Aviation Regulations framework. (header; Applicability; Requirement)\n\nWhat behaviour changes\n\n- Maintenance and engineering teams must implement the modifications or inspections described in British Aerospace Mandatory Service Bulletin 52-JM 7793 on the affected aircraft before the stated compliance date. (Requirement; Compliance)\n- Operators will need to schedule the work into maintenance programs and may temporarily remove affected aircraft from service to complete it. (Requirement; Compliance)\n\nCosts, incentives and trade-offs (mechanisms, not conclusions)\n\n- Direct costs: labour, parts and any downtime to perform the bulletin instructions are borne by the aircraft operator. (Requirement; Compliance)\n- Incentive: complying removes (or reduces) the operational risk of spurious door warning indications as reported; operators therefore gain reduced risk of false warnings tied to the specified systems. (Background)\n- Trade-offs: achieving compliance can impose short-term operational disruption (aircraft out of service until work is done) and maintenance expense; the instrument does not specify funding or compensation. (Requirement; Compliance)\n\nCompliance burden and discretion\n\n- The AD is prescriptive and delegates the technical detail to the referenced Mandatory Service Bulletin; it does not offer alternative corrective actions or explicit exemptions in the text. Operators must follow the service bulletin as the mandated remedy. (Requirement)\n- Implementation depends on availability of the parts and the clarity of the service bulletin; the directive itself provides a compliance deadline but not detailed scheduling guidance. (Requirement; Compliance)\n\nPossible implementation risks and operational effects\n\n- If parts or qualified maintenance resources are limited, operators may face scheduling delays or limited aircraft availability until the work is completed. (Requirement; Compliance)\n- Because the directive references a manufacturer service bulletin, consistent interpretation of the required work depends on that bulletin’s instructions and any associated manufacturer support. (Requirement)\n\nCross-jurisdictional alignment\n\n- The AD explicitly refers to a UK CAA AD, indicating the measure follows or aligns with an overseas airworthiness directive. (Note)\n\nSource references (sections of the instrument used above)\n\n- Applicability: identification of affected aircraft\n- Requirement: mandatory action to follow British Aerospace Mandatory Service Bulletin 52-JM 7793\n- Compliance: deadline (prior to 30 April 1994)\n- Background: reports of spurious door warning indications and systems targeted\n- Note: reference to UK CAA AD 010-08-93"}},"importantCases":[],"_links":{"self":"/api/acts/ad-jetstream-60-passenger-crew-door","history":"/api/acts/ad-jetstream-60-passenger-crew-door/history","analysis":"/api/acts/ad-jetstream-60-passenger-crew-door/analysis","conflicts":"/api/acts/ad-jetstream-60-passenger-crew-door/conflicts","importantCases":"/api/acts/ad-jetstream-60-passenger-crew-door/important-cases","documents":"/api/acts/ad-jetstream-60-passenger-crew-door/documents"}}
