Overview
The Civil Aviation Regulations 1998, specifically Part 39 - 105, establishes the framework through which the Civil Aviation Safety Authority (CASA) issues Airworthiness Directives (ADs) to address safety issues within the aviation sector. In response to reports of fatigue cracks in the body station 1265 edge frame of Boeing 747 series aircraft, which could potentially lead to rapid decompression, CASA issued AD/B747/220 on 9 March 2000. This AD mandates corrective action in accordance with the technical requirements outlined in the Federal Aviation Administration (FAA) AD 2000-02-10 Amdt 39-11529. The directive became effective on 20 April 2000, with compliance to be achieved in line with the specified inspection schedules. The objective of this AD is to mitigate the risk of unsafe conditions that could compromise the structural integrity and safety of the aircraft.
Scope and Application
The Civil Aviation Regulations 1998, specifically Part 39 - 105, pertains to the Civil Aviation Safety Authority’s (CASA) issuance of Airworthiness Directives, which are legal requirements for ensuring the safety of civil aircraft. This particular AD/B747/220 applies to Boeing 747 series aeroplanes as listed in Boeing Alert Service Bulletin 747-53A2416, Revision 1, dated 6 May 1999. The directive mandates corrective action concerning the body station 1265 edge frame between stringers 23 and 27 to address reported fatigue cracks, which could lead to rapid decompression. The directive outlines specific technical requirements, aligning with FAA AD 2000-02-10 Amdt 39-11529, and mandates compliance according to specified inspection schedules with an effective date of 20 April 2000. This directive is applicable nationally, reflecting CASA's jurisdiction over civil aviation safety within Australia, ensuring adherence to stringent safety standards across the industry.
Key Provisions
The Civil Aviation Regulations 1998, particularly in PART 39 - 105, mandate the issuance of Airworthiness Directives (ADs) by the Civil Aviation Safety Authority (CASA) to ensure the safety of aircraft. In the case of the Boeing 747 Series Aeroplanes, the Airworthiness Directive (AD/B747/220) focuses on addressing fatigue cracks at Body Station 1265 Edge Frame (section 4/2000). This directive applies to the Model 747 series aircraft, as specified in Boeing Alert Service Bulletin 747-53A2416, Revision 1, dated 6 May 1999. The directive mandates that the action specified in the FAA AD 2000-02-10 Amdt 39-11529 technical requirements be taken to correct the unsafe condition. The compliance period for these actions is set out in the Requirement document, with a revised effective date of 20 April 2000.
The obligations under this AD include ensuring that all inspections and required actions are carried out according to the specifications provided by the FAA AD 2000-02-10 Amdt 39-11529. Operators and owners of the Boeing 747 series aircraft must adhere to these technical requirements and ensure that the inspections are conducted at the intervals specified in the compliance section of the directive. Failure to comply with these requirements could result in the aircraft being deemed unsafe for operation, thereby posing significant risks to the passengers and crew.
Failure to comply with the Airworthiness Directive can result in severe consequences. The Civil Aviation Safety Authority can impose fines and other penalties for non-compliance. The exact penalties are not specified in the text, but they can include significant financial penalties and the grounding of the aircraft until the required actions are completed. This is to ensure that any potential safety issues are addressed promptly and effectively. Non-compliance can also lead to civil or criminal liability, depending on the severity of the breach and its impact on aviation safety.
