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/B727/180 Main Deck Cargo Door Hinge, Cargo Door System,
and Cargo Barrier - 4
11/2002
Applicability: Model 727 series aircraft that have been converted from a passenger to a cargo- carrying (“freighter”) configuration in accordance with Supplemental Type Certificate (STC) SA1444SO, SA1509SO, SA1543SO, or SA1896SO.
Requirement: Action in accordance with the technical requirements of FAA AD 2002-16-22 Amdt 39-12861.
Note: Accomplishment of the actions in accordance with Pemco Service Bulletin 727-53-0006 Revision 1, dated 4 December 2001, constitutes compliance with the requirements of paragraphs (b) and (c) of the Requirement document.
Compliance: As specified in the Requirement document with a revised effective date of 31 October 2002.
This Airworthiness Directive becomes effective on 31 October 2002.
Background : The FAA has determined that the main deck cargo door hinge installed on conversion from a passenger carrying to a cargo carrying aircraft configuration, is not fail- safe; that certain main deck cargo door control systems do not provide an adequate level of safety; and that the main deck cargo barrier is not structurally adequate during an emergency landing.

The above AD is notified in the Commonwealth of Australia Gazette on 9 October 2002.
Overview
The Civil Aviation Regulations 1998, enacted by the Commonwealth of Australia, serve as the primary legislative instrument governing civil aviation safety in Australia. This Act aims to fill the gap by establishing comprehensive safety standards and regulations to ensure the safety of the national airspace. The Civil Aviation Safety Authority (CASA) issues Airworthiness Directives (ADs) under the authority granted by the Civil Aviation Regulations to address specific safety concerns. One such AD, AD/B727/180, targets the Boeing 727 series aircraft converted from passenger to cargo configurations. This directive was introduced to address safety deficiencies identified in the main deck cargo door hinge, cargo door system, and cargo barrier of these aircraft, following findings by the Federal Aviation Administration (FAA) regarding the unsafe nature of these components in the converted aircraft. The policy objective of AD/B727/180 is to mandate specific corrective actions to mitigate these safety risks, ensuring that these aircraft meet the necessary safety standards before continuing operations.
Scope and Application
The Airworthiness Directive AD/B727/180 pertains specifically to Boeing 727 series aeroplanes that have been converted from a passenger to a cargo-carrying configuration using Supplemental Type Certificates (STC) SA1444SO, SA1509SO, SA1543SO, or SA1896SO. This AD is issued under the Civil Aviation Regulations 1998 by the Civil Aviation Safety Authority (CASA) and aims to address safety concerns identified by the Federal Aviation Administration (FAA) regarding the main deck cargo door hinge, cargo door system, and cargo barrier of these converted aircraft. The AD mandates that the corrective actions detailed in FAA AD 2002-16-22 Amdt 39-12861 be undertaken to mitigate the unsafe conditions identified. Compliance with Pemco Service Bulletin 727-53-0006 Revision 1, dated 4 December 2001, is recognised as fulfilling the requirements of the directive. The AD became effective on 31 October 2002, and its application is limited to the specified aircraft configurations within the Australian jurisdiction.
Key Provisions
The Civil Aviation Regulations 1998, specifically Part 39 - 105, includes provisions for Airworthiness Directives (ADs) issued by the Civil Aviation Safety Authority (CASA). Section 39.1(1) allows a CASA delegate to issue an AD when necessary to correct an unsafe condition in a particular type of aircraft. This particular AD, AD/B727/180, applies to Boeing 727 series aircraft that have been converted from passenger to cargo configurations. The AD mandates specific actions to ensure the safety of the cargo door system and barrier on these aircraft.
The AD requires that the main deck cargo door hinge, cargo door system, and cargo barrier of Boeing 727 series aircraft, which have been converted to freighters using specified Supplemental Type Certificates, must be modified as outlined in FAA AD 2002-16-22 Amdt 39-12861. Compliance with Pemco Service Bulletin 727-53-0006 Revision 1, dated 4 December 2001, is also deemed to satisfy the AD's requirements. The AD specifies that these modifications must be completed by 31 October 2002.
Operators of affected Boeing 727 series aircraft must ensure that all required actions are completed within the specified timeframe. This includes following the technical instructions provided in the FAA AD and Pemco Service Bulletin. Failure to comply with the AD could result in the aircraft being deemed unairworthy, leading to potential grounding and legal repercussions. The AD aims to mitigate risks associated with the main deck cargo door hinge, control systems, and cargo barrier, ensuring the safety of these aircraft during operations.
Non-compliance with the AD may lead to significant legal and operational consequences. The Civil Aviation Safety Authority has the authority to enforce compliance and may take action against operators who fail to adhere to the AD's requirements. Such actions could include fines, penalties, and restrictions on the operation of the aircraft. The AD serves as a critical safety measure, and operators are expected to strictly follow the mandated procedures to avoid any adverse outcomes.
