AIRWORTHINESS DIRECTIVE
For the reasons set out in the background section, the CASA delegate whose signature appears below revokes Airworthiness Directive (AD) AD/B727/97 Amdt 3 and issues the following AD under subregulation 39.1 (1) of CAR 1998. The AD requires that the action set out in the requirement section (being action that the delegate considers necessary to correct the unsafe condition) be taken in relation to the aircraft or aeronautical product mentioned in the applicability section: (a) in the circumstances mentioned in the requirement section; and (b) in accordance with the instructions set out in the requirement section; and (c) at the time mentioned in the compliance section.
Boeing 727 Series Aeroplanes
AD/B727/97
Amdt 4
Supplementary Structural Integrity 10/2002
Applicability: All Model 727 series aircraft.
Requirement: Incorporate the requirements of Boeing 727 Supplemental Structural Inspection Document (SSID) No. D6-48040-1 Volumes 1 and 2, Revision H, dated June 1994, into the aircraft system of maintenance, and inspect in accordance with the technical requirements of FAA AD 98-11-03 R1 Amdt 39-10983.
Compliance: As specified in the Requirement documents. Where there are differences between the FAA AD and Revision H of the SSID, the FAA AD prevails.
This Amendment becomes effective on 3 October 2002.
Background: The Supplemental Structural Inspection Document has been produced to ensure the continued structural integrity of older model 727 aircraft and, by follow- up action, maintain the continuing airworthiness of the Boeing 727 fleet. Amendment 2 reflected the revision status of the SSID.
Amendment 3 expanded applicability and required additional and expanded inspections, and repair of cracked structure.
Amendment 4 is issued in response to a revision of the related FAA AD which corrects the requirements of the current FAA AD by allowing operators not to change their programs if they determine that the existing inspections are effective for the new or affected SSI.
Amendment 3 of this Airworthiness Directive became effective on 10 September 1998.
Amendment 2 of this Airworthiness Directive became effective on 24 October 1985.

The above AD is notified in the Commonwealth of Australia Gazette on 11 September 2002.
Overview
The Civil Aviation Safety Authority (CASA) introduced the Airworthiness Directive (AD) AD/B727/97 Amdt 4 in 2002, specifically addressing the structural integrity of Boeing 727 series aircraft. This directive was enacted to ensure the continued safety and airworthiness of the ageing Boeing 727 fleet by incorporating updated inspection and maintenance requirements. The policy objective of this AD is to correct an identified unsafe condition related to the structural integrity of these aircraft, in alignment with international standards and practices. This legislative instrument revokes the previous amendment (AD/B727/97 Amdt 3) and sets new requirements based on the Boeing 727 Supplemental Structural Inspection Document and FAA AD 98-11-03 R1 Amdt 39-10983. The AD became effective on 3 October 2002, as notified in the Commonwealth of Australia Gazette on 11 September 2002.
Scope and Application
This Airworthiness Directive (AD) applies specifically to all Model 727 series aircraft, necessitating compliance with the regulations outlined for the continued maintenance and airworthiness of these aircraft. The AD mandates the incorporation of the requirements of Boeing 727 Supplemental Structural Inspection Document (SSID) No. D6-48040-1 Volumes 1 and 2, Revision H, dated June 1994, into the aircraft's maintenance system and mandates inspections in accordance with the technical requirements of FAA AD 98-11-03 R1 Amdt 39-10983. The AD requires adherence to the instructions and timelines specified within the requirement and compliance sections, and it becomes effective from 3 October 2002. In cases where there are discrepancies between the FAA AD and Revision H of the SSID, the FAA AD is to take precedence. This legislative instrument, issued by the delegate of the Civil Aviation Safety Authority, has the full force of law within the Commonwealth of Australia.
Key Provisions
The main sections of the Airworthiness Directive (AD) AD/B727/97 Amdt 4 are the applicability, requirement, and compliance sections. The applicability section (subsection 10) states that the directive applies to all Model 727 series aircraft. The requirement section (subsection 11) mandates that Boeing 727 Supplemental Structural Inspection Document (SSID) No. D6-48040-1 Volumes 1 and 2, Revision H, dated June 1994, must be integrated into the aircraft's maintenance system and inspected according to the technical requirements of FAA AD 98-11-03 R1 Amdt 39-10983. The compliance section (subsection 12) specifies that the directive must be adhered to as per the requirements set out in the documents, with FAA AD prevailing in case of discrepancies.
The obligations and requirements imposed by this AD on the parties or entities it governs include integrating the specified SSID revision into the aircraft's maintenance system and conducting inspections in accordance with FAA AD 98-11-03 R1 Amdt 39-10983. The directive also mandates that where there are differences between the FAA AD and Revision H of the SSID, the FAA AD must be followed. This directive becomes effective on 3 October 2002.
Failure to comply with the AD could result in serious safety concerns, potentially leading to structural failure of the aircraft. Although the legislation does not explicitly state specific penalties or consequences for non-compliance, it is implied that non-compliance with ADs is a serious matter under the Civil Aviation Safety Authority (CASA) regulations, and it could lead to enforcement actions, fines, or grounding of the aircraft. The exact penalties would be determined based on the severity of the non-compliance and the specific circumstances surrounding it.
