Overview
The Civil Aviation Regulations 1998, specifically Part 39 - 105 of the Civil Aviation Safety Authority's Schedule of Airworthiness Directives, was enacted to ensure the safety and airworthiness of aircraft in Australia. The Civil Aviation (Airworthiness of Aircraft) Regulations 1998 address the problem of unsafe conditions in aircraft that could potentially lead to accidents and loss of life. This particular Airworthiness Directive (AD) pertains to Boeing 737 Series Aeroplanes and was issued by the Civil Aviation Safety Authority (CASA) to rectify an identified unsafe condition. The policy objective of this AD is to mandate specific actions to be taken on certain aircraft models to prevent incidents related to tie bolt failures in the main landing gear wheel assemblies, ensuring the safety of all passengers and crew.
Scope and Application
The Airworthiness Directive AD/B737/132 pertains to all Boeing 737 series aeroplanes, specifically the Model 737-100, -200, -300, -400, and -500. It was issued by the Civil Aviation Safety Authority (CASA) to address safety concerns identified with the main landing gear tie bolts of these aircraft. The directive mandates compliance with the technical requirements of the Federal Aviation Administration (FAA) AD 99-19-27 Amendment 39-11314, with CASA-approved maintenance programs substituting for FAA-approved programs. The primary objective of this AD is to rectify issues related to multiple tie bolt failures on BFGoodrich wheel assemblies, which could lead to significant damage and injury if left unaddressed. Compliance with the directive must be achieved by adhering to the specified requirements, with a revised effective date of 30 December 1999. The AD was further amended to correct a typographical error, with the amendment becoming effective on 24 February 2000. This directive applies within the Commonwealth of Australia and is notified in the Commonwealth of Australia Gazette.
Key Provisions
The Airworthiness Directive (AD) AD/B737/132 Amendment 1 (F2006B02833) issued by the Civil Aviation Safety Authority (CASA) concerns the maintenance and safety requirements for all Boeing 737 series aircraft, specifically models 737-100, -200, -300, -400, and -500. The directive mandates actions to address unsafe conditions identified in the main landing gear tie bolts of these aircraft (s 2(a), (b), (c)). The required actions must be taken in accordance with the technical specifications outlined in FAA AD 99-19-27 Amendment 39-11314, with CASA-approved maintenance programs substituted for FAA-approved ones as per CASA's approval (s 2(a)). The directive requires compliance with the amended effective date of 30 December 1999, and the compliance period remains unchanged (s 2(c)).
Entities governed by this AD must ensure that maintenance and repair of the main landing gear tie bolts are performed in strict accordance with the specified technical requirements. This involves replacing or repairing the tie bolts to prevent failures that could lead to severe consequences, including damage to the aircraft and potential injuries to passengers and crew (s 2). Operators and maintenance personnel must adhere to the CASA-approved maintenance programs and ensure that all procedures are meticulously followed to maintain airworthiness standards (s 2). Failure to comply with these requirements can result in significant safety risks, including aircraft damage, potential accidents, and injuries.
Failure to comply with the provisions of AD/B737/132 Amendment 1 can lead to serious consequences. The Civil Aviation Safety Authority (CASA) can impose both civil and criminal penalties for non-compliance. Civil penalties can include fines up to the maximum amount prescribed by the Civil Aviation Act 1988. Additionally, criminal penalties can be applied, potentially resulting in imprisonment, fines, or both, depending on the severity of the breach and the extent of the unsafe condition (s 3). The seriousness of the potential consequences underscores the importance of strict adherence to the AD's requirements.
