Overview

The Civil Aviation Regulations 1998 (CAR 1998), specifically under Part 39 - 105, establishes the framework through which the Civil Aviation Safety Authority (CASA) can issue Airworthiness Directives (ADs) to ensure the safety of civil aviation. The AD/B737/191 issued in 2002 pertains to Boeing 737 Series Aeroplanes, particularly models 737-600, -700, and -800 within specific line numbers. This directive was introduced in response to reports of damaged engine aft strut insulation blankets on these aircraft, which could potentially lead to catastrophic outcomes such as fuel tank explosions and fires. The AD mandates corrective actions in line with the technical requirements set out by the Federal Aviation Administration (FAA) through AD 99-04-11 Amdt 39-11035. The policy objective behind this AD is to mitigate the identified safety risks by ensuring that the specified aircraft are maintained to a standard that precludes such hazardous conditions. The AD/B737/191 was issued by David Alan Villiers, a delegate of CASA, on 12 September 2002, and it became effective on 31 October 2002. This legislative instrument was subsequently notified in the Commonwealth of Australia Gazette on 9 October 2002. The enactment of this AD by the Civil Aviation Safety Authority underscores the importance of continuous monitoring and rapid response to emerging safety issues in civil aviation, ensuring that all stakeholders adhere to stringent safety standards to protect both the aircraft and those onboard.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, govern the issuance of Airworthiness Directives (ADs) by the Civil Aviation Safety Authority (CASA) to address safety concerns in aviation. The scope of this particular AD, AD/B737/191, pertains to Boeing 737 series aeroplanes, namely the Model 737-600, -700, and -800 aircraft, with line numbers ranging from 1 to 64. The AD mandates that specific action be taken to rectify the unsafe condition of damaged engine aft strut insulation blankets, as outlined in the requirement section, to prevent potential fuel ignition and fire risks. The directive applies nationwide, within the Commonwealth of Australia, and is issued in accordance with the authority granted under subregulation 39.1 (1) of the Civil Aviation Regulations 1998. Compliance with this AD is mandatory for the specified aircraft models within the designated line numbers, and failure to adhere to the outlined requirements could result in regulatory action. The AD was made effective on 31 October 2002, with a revised effective date published in the Commonwealth of Australia Gazette on 9 October 2002.

Key Provisions

The Civil Aviation Regulations 1998, specifically Part 39 - 105, includes Airworthiness Directives (ADs) issued by the Civil Aviation Safety Authority (CASA). The ADs are regulatory instruments that require certain actions to be taken to address safety concerns in aircraft or aeronautical products. Section 39.1 (1) of the Civil Aviation Regulations 1998 empowers the CASA delegate to issue these directives to ensure the continued airworthiness of the aircraft. This particular AD (AD/B737/191) pertains to Boeing 737 Series Aeroplanes, specifically models 737-600, -700, and -800 within certain line numbers. The AD mandates that the action specified in the Requirement section must be taken to address the issue of damaged engine aft strut insulation blankets. The directive requires compliance with the technical requirements outlined in FAA AD 99-04-11 Amdt 39-11035. The Boeing Alert Service Bulletin 737-54A1038 is also referenced as additional guidance material. The directive became effective on 31 October 2002. The obligations imposed by this AD require the aircraft operators and owners to follow the specified requirements and instructions to ensure the safety of the aircraft. This includes addressing the damaged engine aft strut insulation blankets in accordance with the FAA AD 99-04-11 Amdt 39-11035 and any related Boeing service bulletins. The AD also mandates that these actions be taken by the specified compliance date of 31 October 2002. Failure to comply with the AD may result in various civil and criminal consequences. While specific penalties are not detailed within the AD itself, non-compliance with CASA directives can lead to enforcement actions by CASA, which may include fines, suspension, or revocation of an aircraft's Certificate of Airworthiness. Additionally, there may be potential criminal liability for individuals or entities responsible for the non-compliance, depending on the circumstances and any relevant legislation. The exact penalties will depend on the nature and extent of the non-compliance, as well as any applicable laws and regulations.
