Requirement: Action IAW the technical requirements of FAA AD 96-23-02 Amdt 39-9807.
Note: Boeing Service Bulletins 747-53A2409, 747-53A2321, and 747-53-2272 refer.
Compliance: As specified in the Requirement Document with an effective date of 27 February 1997.
This amendment becomes effective on 27 February 1997.
Background: The FAA received a report of skin cracking due to disbonding of the internal doubler of the cracked skin panels. The actions required by this Directive are intended to prevent rapid decompression of the aircraft due to disbonding and subsequent cracking of the skin panels.
Amendment 1 corrects an error with the effective date of the AD. The new effective date is now 27 February 1997.
The original issue of this Airworthiness Directive was issued on 18 December 1996.
Overview
The Civil Aviation Regulations 1998, enacted by the Parliament of Australia, address the safety and regulation of civil aviation within the country. Specifically, Part 39 of the Regulations, which pertains to the Civil Aviation Safety Authority, includes detailed provisions on airworthiness directives to ensure the safe operation of aircraft. One such directive, AD/B747/167, applies to Boeing 747 series aeroplanes and aims to address the problem of skin cracking due to the disbonding of internal doublers in certain skin panels. This problem was identified through reports of structural issues that could potentially lead to rapid decompression if not properly managed. The directive mandates actions in line with the technical requirements set by the Federal Aviation Administration's AD 96-23-02 Amdt 39-9807, with a compliance deadline of 27 February 1997, ensuring that the affected aircraft maintain their airworthiness and safety standards.
Scope and Application
The Civil Aviation Regulations 1998, specifically Part 39 - 105 concerning the Civil Aviation Safety Authority's Schedule of Airworthiness Directives, addresses the mandatory compliance requirements for Boeing 747 series aeroplanes. The regulation applies to all Boeing 747 series aircraft, covering specific line numbers that have undergone certain modifications. For instance, it applies to line numbers 1 through 200 where the skin panel replacement specified in Boeing Service Bulletin 747-53A2321 has been completed, line numbers 201 through 430 that have been modified to a Stretched Upper Deck (SUD) configuration, and line numbers 431 through 1075. The directive mandates compliance with the technical requirements outlined in FAA AD 96-23-02 Amdt 39-9807, ensuring that these aircraft meet specific airworthiness standards to prevent rapid decompression due to skin panel disbonding and cracking. Compliance with the directive is expected to be achieved as per the requirements documented, with an effective date of 27 February 1997. The regulation is applicable across the Commonwealth of Australia, reinforcing the importance of stringent safety standards in civil aviation.
Key Provisions
The Civil Aviation Regulations 1998, specifically Part 39, Section 105, includes an amendment to the Boeing 747 series aircraft (Section 41) concerning bonded skin panels. The amendment applies to different line numbers of the 747 series aircraft. Line numbers 1 through 200 must follow the technical requirements of FAA AD 96-23-02 Amendment 39-9807, line numbers 201 through 430 must be modified to a Stretched Upper Deck (SUD) configuration, and line numbers 431 through 1075 must comply with the specified requirements. The compliance is required as per the Requirement Document, effective from 27 February 1997. The background of this directive is based on a report of skin cracking due to disbonding of the internal doubler of the cracked skin panels, aiming to prevent rapid decompression of the aircraft due to disbonding and subsequent cracking of the skin panels.
The Civil Aviation Regulations 1998, under Part 39, Section 105, imposes obligations on the entities involved in the operation and maintenance of Boeing 747 series aircraft. The entities must ensure that the technical requirements of FAA AD 96-23-02 Amendment 39-9807 are followed for line numbers 1 through 200, the Stretched Upper Deck (SUD) configuration is implemented for line numbers 201 through 430, and the specified requirements are met for line numbers 431 through 1075. The compliance must be in line with the Requirement Document, effective from 27 February 1997. This requirement is intended to prevent rapid decompression of the aircraft due to disbonding and subsequent cracking of the skin panels, as reported in the background information.
The Civil Aviation Regulations 1998, under Part 39, Section 105, includes provisions for offences, penalties, and consequences for breach. While specific details on penalties are not provided in the text, it is implied that non-compliance with the requirements could result in civil or criminal consequences. The maximum penalties for such breaches are not explicitly stated in the text. The primary focus of this legislation is on ensuring the airworthiness of Boeing 747 series aircraft by preventing rapid decompression due to disbonding and subsequent cracking of the skin panels. Compliance with the specified requirements and adherence to the effective date of 27 February 1997 is crucial to avoid potential penalties and consequences.
