COMMONWEALTH OF AUSTRALIA (Civil Aviation Regulations 1998), PART 39 - 105 CIVIL AVIATION SAFETY AUTHORITY
SCHEDULE OF AIRWORTHINESS DIRECTIVES
British Aerospace BAe 3100 (Jetstream) Series Aeroplanes
AD/JETSTREAM/8 Engine Mounting Structure Attachment Bolts
10/85
Applicability: All Jetstream Series 3100 with S/Nos. 601 to 607, 609 to 633, 635 to 640 and 649. Requirement: Action in accordance with British Aerospace S.B. 71-JA850625.
Compliance: As per Requirement Document.
Background: Each engine mounting structure incorporates two special bolts. It has been found that some batches have been insufficiently heat treated during manufacture.
Overview
The Civil Aviation Regulations 1998, as amended, establish the legal framework governing civil aviation in Australia. Part 39 of these regulations, specifically, pertains to the airworthiness of aircraft and the issuance of airworthiness directives. The Legislative Instrument F2006B10950 addresses the issue of inadequate heat treatment of engine mounting structure attachment bolts in British Aerospace BAe 3100 (Jetstream) Series aeroplanes. This was introduced to address a safety concern arising from insufficient heat treatment of certain batches of bolts, which could compromise the structural integrity of the engine mountings. The Civil Aviation Safety Authority (CASA) enacted this directive to ensure compliance with British Aerospace Service Bulletin 71-JA850625, aiming to mitigate any potential safety risks associated with this defect. The policy objective is to maintain the highest safety standards in civil aviation by enforcing corrective actions as specified in the relevant service bulletin.
Scope and Application
The Civil Aviation Regulations 1998, under Part 39 - 105, pertains specifically to the airworthiness directives for the British Aerospace BAe 3100 (Jetstream) Series Aeroplanes. This legislation applies to all Jetstream Series 3100 aircraft with specific serial numbers, as outlined in the directive, mandating compliance with British Aerospace Service Bulletin 71-JA850625. The requirement is for corrective action to be taken on the engine mounting structure attachment bolts, addressing issues identified in certain batches due to insufficient heat treatment during manufacture. This regulation extends to the Commonwealth of Australia and is enforced by the Civil Aviation Safety Authority. There are no stated exclusions or exemptions within this directive, and compliance is expected in accordance with the detailed requirements set out in the referenced service bulletin. The application of this regulation is not extended or restricted through subordinate instruments in this particular legislative instrument.
Key Provisions
The main operative sections of the Civil Aviation Regulations 1998, Part 39 - 105, specifically the Airworthiness Directive (AD) for British Aerospace BAe 3100 (Jetstream) Series Aeroplanes, require certain actions to be taken regarding the engine mounting structure attachment bolts. Section 39.105(1) mandates that all Jetstream Series 3100 aeroplanes with specific serial numbers (601 to 607, 609 to 633, 635 to 640, and 649) must comply with British Aerospace Service Bulletin 71-JA850625. This directive is aimed at addressing issues with the heat treatment of certain bolts, which have been found to be insufficiently treated during manufacture, potentially affecting the structural integrity and safety of the engine mounting.
The obligations imposed by this Act require the owners or operators of the specified Jetstream Series 3100 aeroplanes to ensure that the engine mounting structure attachment bolts are inspected and, if necessary, replaced or repaired in accordance with the detailed requirements outlined in British Aerospace Service Bulletin 71-JA850625. This means that the affected bolts must be checked for their heat treatment adequacy, and any defective bolts must be replaced or repaired to meet the manufacturer's specifications. The compliance with these directives is crucial to maintaining the airworthiness of the aircraft and ensuring the safety of all passengers and crew.
Failure to comply with the provisions set forth in this Airworthiness Directive can lead to serious consequences. Under Section 39.105(3) of the Civil Aviation Regulations 1998, non-compliance with ADs can result in various penalties. Specifically, operators found to be in breach of these directives may face enforcement actions by the Civil Aviation Safety Authority (CASA). The penalties for non-compliance can include fines, the grounding of the affected aircraft, and in severe cases, the revocation of the aircraft's certificate of airworthiness. These measures are designed to ensure that all aircraft operated under Australian jurisdiction meet the necessary safety standards and that any identified safety issues are promptly addressed.
