Overview
The Civil Aviation Regulations 1998, enacted by the Commonwealth of Australia, form a comprehensive regulatory framework governing civil aviation safety. Part 39 of these regulations specifically addresses the safety of aircraft, including the issuance of Airworthiness Directives to ensure the continued airworthiness of specific aircraft models. One such directive, AD/B727/132, pertains to the Boeing 727 Series Aeroplanes, focusing on the model’s Number Two Cargo Doorway Frames. This directive was introduced to address the critical safety issue of cracks in the forward and aft frame webs, which could potentially lead to the failure of the No. 2 cargo doorway frames and subsequent depressurisation of the aircraft. The directive mandates compliance with the Technical Requirements of FAA AD 91-07-11 Amdt 39-6946, with a revised effective date of 13 June 1991 for Australian registered aircraft. The policy objective behind this regulation is to mitigate safety risks and ensure the structural integrity of aircraft, thereby protecting passengers and crew.
Scope and Application
The Civil Aviation Regulations 1998, specifically Part 39 - 105, mandates the application of Airworthiness Directives (AD) concerning Boeing 727 Series Aeroplanes, particularly focusing on the Number Two Cargo Doorway Frames as outlined in AD/B727/132. This legislation applies to all Boeing 727 series aeroplanes that are listed in Boeing Alert Service Bulletin (SB) 727-53A 0199, ensuring that the safety concerns identified by the Federal Aviation Administration (FAA) are addressed. The directive requires actions to be taken in accordance with the Technical Requirements of FAA AD 91-07-11 Amdt 39-6946, with compliance strictly enforced as specified in the requirement document. The effective date for compliance, initially set by the FAA, has been revised to 13 June 1991 for Australian registered aircraft, extending the compliance period by six weeks. This legislation is instrumental in mitigating the risk of structural failure in the No. 2 cargo doorway frames, which could potentially lead to depressurisation of the aircraft.
Key Provisions
The Civil Aviation Regulations 1998, Part 39 - 105, under the Civil Aviation Safety Authority, includes specific Airworthiness Directives (AD) for various aircraft models, including the Boeing 727 Series Aeroplanes. One such AD is AD/B727/132, which pertains to the No. 2 Cargo Doorway Frames. This directive applies to the Boeing 727 series aeroplanes as listed in Boeing Alert SB 727-53A 0199 (section 1). The directive mandates compliance with the Technical Requirements of FAA AD 91-07-11 Amdt 39-6946, which includes a revised effective date of 13 June 1991 for Australian registered aircraft. The directive is designed to address reports of cracks in the forward and aft frame webs, which, if unaddressed, could lead to the failure of the No. 2 cargo doorway frames and subsequent depressurisation of the aircraft.
The obligations under this AD require operators of Boeing 727 series aeroplanes to follow the specific technical requirements outlined in the FAA AD 91-07-11 Amdt 39-6946. This includes conducting necessary inspections and repairs to ensure the structural integrity of the No. 2 cargo doorway frames. Operators must ensure that the aircraft comply with the AD by the revised effective date of 13 June 1991. This involves adhering to the guidelines provided in the requirement document and addressing any identified issues promptly to maintain airworthiness.
Failure to comply with the AD/B727/132 can lead to severe consequences. The regulations stipulate that non-compliance may result in civil or criminal penalties, depending on the severity of the breach. In particular, failure to adhere to the Airworthiness Directives can lead to penalties under the Civil Aviation Act 1988. Civil penalties for non-compliance can include substantial fines, while criminal penalties may involve imprisonment for serious breaches that endanger safety. The exact penalties depend on the specific nature of the violation and the discretion of the court, but the potential for significant financial and legal repercussions underscores the importance of strict adherence to the directive.
