COMMONWEALTH OF AUSTRALIA (Civil Aviation Regulations 1998), PART 39 - 105 CIVIL AVIATION SAFETY AUTHORITY
SCHEDULE OF AIRWORTHINESS DIRECTIVES
Boeing 727 Series Aeroplanes
AD/B727/118
Amdt 1
Structural Modification Program 6/95
Applicability: All model B727 aircraft listed in Boeing Document D6-54860, “Ageing Aircraft Service Bulletin Structural Modification and Inspection Program - Model 727" Revision G, dated March 5, 1993.
Requirement: 1. Modify in accordance with Boeing document D6-54860 Revision G, Section 3.
2. Modify in accordance with Boeing Document D6-54860 Revision G, Appendices A.3, B.3 and C.3.
Note: FAA ADs 90-06-09 and 94-05-04 refer.
Compliance: 1. Modify in accordance with the incorporation thresholds listed in Requirement Document Section 3 or before 17 April 1994, whichever is the later. Modifications for which the incorporation threshold is identified as a specific date shall be accomplished at that date.
The compliance for Requirement 1 is unchanged from the original issue of this AD.
2. Modify in accordance with the incorporation thresholds listed in Requirement Document Appendices A.3, B.3 and C.3 or before 25 May 1999, whichever is the later.
Background: The FAA sponsored Ageing Fleet Conference was tasked with identifying and implementing procedures to ensure the continuing airworthiness of high time aircraft. This AD requires modifications in lieu of those inspections which were considered to not be as effective as desired. The initial issue of this AD referenced FAA AD
90-06-09. This amendment also references FAA AD 94-05-04 which, in turn, references D6-54860 Revision G, and adds Appendices A.3, B.3 and C.3 modifications.
Overview
The Civil Aviation Regulations 1998, introduced by the Australian Government, aim to maintain and enhance aviation safety standards across the nation. Part 39, specifically, encompasses various airworthiness directives designed to ensure that aircraft remain in a safe condition for operation. One such directive is AD/B727/118 Amendment 1, targeting Boeing 727 Series Aeroplanes. This directive was enacted to address the problem of ageing aircraft and to implement necessary structural modifications to ensure continued airworthiness. It was developed following recommendations from the FAA sponsored Ageing Fleet Conference, which sought to enhance safety measures for high time aircraft. The primary objective of this directive is to mandate modifications that are deemed more effective than certain inspections, thereby ensuring that all model B727 aircraft comply with the specified requirements and thresholds, ultimately contributing to the overarching goal of maintaining high safety standards in civil aviation.
Scope and Application
The Civil Aviation Regulations 1998, specifically Part 39 - 105, applies to all Boeing 727 series aeroplanes listed in Boeing Document D6-54860, “Ageing Aircraft Service Bulletin Structural Modification and Inspection Program - Model 727" Revision G, dated March 5, 1993. This legislation mandates structural modifications to ensure the continuing airworthiness of these aircraft, particularly those considered to be high time aircraft. The modifications outlined are required in accordance with the specific Boeing document, with two distinct requirements: the first necessitates modifications by 17 April 1994 or according to the incorporation thresholds detailed in Requirement Document Section 3, while the second requires modifications by 25 May 1999 or in accordance with the thresholds listed in Appendices A.3, B.3 and C.3. This legislative instrument is a Commonwealth regulation, impacting all entities and individuals involved in the operation of Boeing 727 aircraft within Australia. The Civil Aviation Safety Authority oversees compliance with these directives, ensuring that all modifications are completed to maintain safety standards in the aviation industry.
Key Provisions
The Civil Aviation Regulations 1998, Part 39 - 105, specifically in relation to Boeing 727 Series Aeroplanes, mandates a structural modification program as outlined in AD/B727/118 Amendment 1 dated 6/95. This legislative instrument requires all model B727 aircraft listed in Boeing Document D6-54860, "Ageing Aircraft Service Bulletin Structural Modification and Inspection Program - Model 727" Revision G, dated March 5, 1993, to undergo specific structural modifications. The requirements are detailed in two primary sections: the first mandates modifications in accordance with Section 3 of the Boeing document, and the second mandates modifications according to Appendices A.3, B.3, and C.3 of the same document. The directive notes that these modifications are in lieu of inspections deemed less effective, as highlighted in FAA ADs 90-06-09 and 94-05-04.
Entities governed by this Act are obligated to adhere to the structural modification thresholds and deadlines specified in the Boeing document. For Requirement 1, modifications must align with the incorporation thresholds listed in Section 3 or be completed before April 17, 1994, whichever is later. For Requirement 2, modifications must comply with the thresholds in Appendices A.3, B.3, and C.3 or be completed before May 25, 1999, whichever is later. These obligations ensure that the structural integrity of the aircraft is maintained in line with safety standards and regulatory requirements.
Failure to comply with the specified modifications and deadlines can result in serious consequences. The Act does not explicitly state the penalties or consequences for non-compliance; however, it is implied that non-compliance with Civil Aviation Regulations can lead to significant legal repercussions. This could include enforcement actions by the Civil Aviation Safety Authority (CASA), potential grounding of the aircraft, and possible criminal charges if the non-compliance results in safety incidents. The precise penalties would be determined based on the severity of the non-compliance and its impact on aviation safety.
