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/27
Amdt 1
Shear Angles at Wing Rib 36 11/96
Applicability: Jetstream Series 3100 series aircraft, that do not have modification JM5303 embodied.
Requirement: Action in accordance with Jetstream Aircraft Alert Service Bulletin 57-A-JA 880144 Revision 2.
Compliance: As specified in the requirement document.
The compliance of the initial issue of this directive remains unchanged for the inspection intervals. This amendment is effective from 10 October 1996.
Background: The cracking of shear angles was reported, and also detected by Jetstream fatigue testing.
Amendment 1 is raised in response to the latest revision of the requirement document which is issued because the Accomplishment Instructions at the previous issue standard are potentially misleading.
The original issue of this airworthiness directive became effective on 6 October 1988.
Overview
The Civil Aviation Regulations 1998, specifically Part 39, was enacted by the Australian Parliament to regulate and ensure the safety and airworthiness of civil aircraft within Australian airspace. Among the various amendments and directives, the AD/JETSTREAM/27 Amendment 1 addresses specific concerns related to the British Aerospace BAe 3100 (Jetstream) Series Aeroplanes, particularly the shear angles at Wing Rib 36. This directive was introduced to tackle issues of structural integrity as evidenced by reported cracking and detected during fatigue testing, which could potentially compromise the safety of the aircraft. The policy objective is to ensure compliance with the latest revisions of the requirement document to prevent misleading instructions and maintain the safety standards set forth by the Civil Aviation Safety Authority. The amendment is effective from 10 October 1996, aiming to rectify potentially misleading instructions from the previous standard.
Scope and Application
The Civil Aviation Regulations 1998, specifically Part 39 - 105 concerning the Civil Aviation Safety Authority Schedule of Airworthiness Directives, applies to Jetstream Series 3100 series aircraft that do not incorporate modification JM5303. This regulation mandates compliance with Jetstream Aircraft Alert Service Bulletin 57-A-JA 880144 Revision 2, outlining the necessary actions to address the shear angles at Wing Rib 36, a concern identified through reported cracking and fatigue testing. Compliance with this directive must adhere to the specifications detailed in the requirement document. The initial directive's compliance requirements remain unaltered regarding inspection intervals, and this amendment took effect from 10 October 1996. This regulation is applicable across the Commonwealth of Australia, ensuring that all relevant aircraft meet the specified airworthiness standards. The directive does not explicitly mention any exclusions or exemptions, suggesting that all applicable aircraft must comply unless otherwise specified through subordinate instruments or additional amendments.
Key Provisions
The Civil Aviation Regulations 1998, specifically Part 39 - 105, outlines the requirements for the maintenance and operation of aircraft within Australia, ensuring they meet the necessary safety standards. One of the key provisions is the Schedule of Airworthiness Directives, which includes directives specific to various aircraft types. For instance, AD/JETSTREAM/27 Amendment 1 (section 39-105) pertains to the British Aerospace BAe 3100 (Jetstream) series aeroplanes. This directive addresses the issue of shear angles at Wing Rib 36, requiring compliance with the latest version of the Jetstream Aircraft Alert Service Bulletin 57-A-JA 880144 Revision 2.
This directive applies to Jetstream Series 3100 aircraft that do not have the modification JM5303 incorporated. The requirement is straightforward: operators must follow the instructions specified in the Jetstream Aircraft Alert Service Bulletin 57-A-JA 880144 Revision 2. Compliance with this directive is essential to address the reported cracking of shear angles, a critical safety concern identified through both operational incidents and fatigue testing. The compliance protocol and inspection intervals remain consistent with the initial issue of the directive, which was first implemented on 6 October 1988, with Amendment 1 taking effect from 10 October 1996.
The obligations imposed by this Act on the operators of Jetstream Series 3100 aircraft are to ensure that they adhere strictly to the maintenance and inspection protocols outlined in the referenced service bulletin. This involves conducting the necessary inspections and repairs to mitigate the risk of structural failure due to shear angle cracking. Operators must also ensure that any modifications or repairs are carried out by qualified personnel following the detailed instructions provided in the bulletin. Regular documentation and record-keeping are mandatory to demonstrate compliance with the airworthiness directive.
Failure to comply with the requirements of this directive can lead to severe consequences. Non-compliance may result in the aircraft being deemed unairworthy, leading to potential grounding until the required repairs and inspections are completed. Additionally, operators found in breach of the directive may face regulatory action, including fines and sanctions, as stipulated by the Civil Aviation Safety Authority. The penalties for non-compliance are designed to enforce adherence to safety standards and protect public safety in aviation operations. The maximum penalties can include substantial fines and, in severe cases, criminal charges for those responsible for the oversight.
