The above AD is notified in the Commonwealth of Australia Gazette on 21 April 2004.
Overview
The Civil Aviation Safety Regulations 1998, amended by the Civil Aviation Safety Regulations 1998 (Amendment) 2004, include an Airworthiness Directive issued by the Civil Aviation Safety Authority (CASA) to address safety concerns related to the Boeing 727 Series Aeroplanes, specifically targeting the forward and aft frames of the aft cargo door opening. This Airworthiness Directive, numbered AD/B727/187, was issued on 5 May 2004 by David Villiers, a delegate of CASA, in response to findings of potential cracks in the specified areas of the aircraft which could lead to catastrophic failure of the aft cargo door and subsequent rapid decompression. The directive mandates that any detected cracks be repaired according to the technical requirements set out in FAA AD 2004-03-30 Amdt 39-13474, either by a method approved by the Manager, Seattle Aircraft Certification Office (ACO), FAA, or by a Boeing Company Designated Engineering Representative (DER) authorised by the Manager, Seattle ACO. The directive became effective on 13 May 2004, ensuring that necessary safety measures were promptly implemented to mitigate the identified risk.
Scope and Application
The Civil Aviation Safety Regulations 1998, specifically Part 39 - 105, governs the scope and application of the Airworthiness Directive issued by the Civil Aviation Safety Authority (CASA) under the authority delegated by the Commonwealth of Australia. This directive applies to the Boeing 727 Series Aeroplanes, including models 727, 727C, 727-100, and 727-100C, as referenced in Boeing Alert Service Bulletin 727-53A0225 dated 11 September 2003. The directive mandates that corrective action must be taken if any crack is detected in the forward and aft frames of the aft cargo door opening. Such action includes repairing the crack before further flight, in accordance with the technical requirements of the Federal Aviation Administration's Airworthiness Directive 2004-03-30 Amdt 39-13474, and must be carried out by a method approved by the Manager, Seattle Aircraft Certification Office (ACO), FAA, or by a Boeing Company Designated Engineering Representative (DER) authorised by the Manager, Seattle ACO. The compliance period for this directive is set out in the requirement document with an effective date of 13 May 2004. This Airworthiness Directive is applicable across the Commonwealth of Australia and is enforced to prevent potential loss of the aft cargo door and rapid decompression of the aircraft due to detected cracks.
Key Provisions
The Civil Aviation Safety Regulations 1998, particularly under Part 39, contain specific Airworthiness Directives (ADs) aimed at ensuring the safety of aircraft and aeronautical products. One such AD, AD/B727/187, pertains to the Boeing 727 series aircraft, including models 727, 727C, 727-100, and 727-100C, and is designed to address cracks in the forward and aft frames of the aft cargo door opening (section 39.105). The AD was issued by a delegate of the Civil Aviation Safety Authority (CASA) under subregulation 39.1 (1) and mandates actions to be taken in response to identified unsafe conditions.
The AD requires that any identified cracks in the specified areas of the aircraft be repaired before further flight. This repair must be conducted in accordance with the technical requirements of FAA AD 2004-03-30 Amdt 39-13474, which allows for repair methods approved by the Manager, Seattle Aircraft Certification Office (ACO), FAA, or by a Boeing Company Designated Engineering Representative (DER) who has been authorised by the Manager, Seattle ACO, to make such findings (section 39.105). This ensures that the repairs meet the necessary safety standards and are carried out by qualified personnel.
The obligations under this AD include conducting thorough inspections to detect any cracks in the specified areas of the aircraft, repairing such cracks before further flight, and ensuring that all repairs are performed by authorised personnel in accordance with the technical requirements outlined. The compliance section stipulates that these actions must be taken by a specific date, with the AD becoming effective on 13 May 2004. Failure to comply with this AD can result in serious safety risks, including the potential loss of the aft cargo door and rapid decompression of the aircraft.
There are significant consequences for non-compliance with the AD. The AD specifies that failure to adhere to the requirements can lead to safety issues, including the potential for the aft cargo door to detach, resulting in rapid decompression. The regulations do not explicitly outline specific penalties for non-compliance, but such failure can be considered a serious breach of aviation safety standards, potentially leading to severe civil or criminal consequences under broader aviation safety laws.
