AD/B767/22 Amdt 2 - Engine Overheat, Fire Detection and Fire Extinguishing Systems

Overview

The Civil Aviation Regulations 1998, as part of Part 39 - 105 Civil Aviation Safety Authority Schedule of Airworthiness Directives, address issues pertaining to the safety of aviation systems, particularly focusing on the prevention of engine overheat, fire detection, and fire extinguishing systems in Boeing 767 series aircraft. This legislation was enacted to ensure that all Boeing 767 series aircraft are equipped with properly functioning fire detection and extinguishing systems, thereby mitigating the risks associated with potential engine fires. The Civil Aviation Safety Authority, under the authority of the Commonwealth of Australia, issued this directive to address the identified problem of improperly installed wiring and/or plumbing in the fire protection systems, which could lead to significant safety hazards. The policy objective of this directive is to enforce mandatory functional checks and maintenance of specified systems to ensure airworthiness and passenger safety.

Scope and Application

The Civil Aviation Safety Authority Schedule of Airworthiness Directives under the Civil Aviation Regulations 1998 applies to all Boeing 767 series aircraft. This regulatory requirement focuses on the engine overheat, fire detection, and fire extinguishing systems within these aircraft, aiming to ensure their safety and compliance with aviation standards. The directive mandates functional checks of the engine fire/overheat detection and warning systems, engine fire extinguishing system wiring and plumbing, lower cargo compartment smoke/fire detection system, and cargo compartment fire extinguishing system wiring and plumbing, as specified in the referenced Boeing telexes and FAA amendments. Compliance with these directives is mandatory, with specific timelines set for initial and subsequent checks, particularly following any maintenance work that could affect these critical systems. The directive extends to all operators of Boeing 767 series aircraft, ensuring that these safety measures are uniformly applied across the industry. There are no stated exclusions or exemptions in this directive, thereby ensuring a comprehensive approach to addressing potential fire hazards in these aircraft. The application of this Act is reinforced through subordinate instruments, which provide detailed guidance and updates to the compliance requirements, ensuring that the safety directives remain current and effective.

Key Provisions

The Civil Aviation Regulations 1998, under Part 39, specify the airworthiness directives (AD) for certain aircraft, including the Boeing 767 series aeroplanes. AD/B767/22 Amendment 2 addresses the engine overheat, fire detection, and fire extinguishing systems of all Boeing 767 aircraft. This directive requires operators to conduct functional checks on the engine fire/overheat detection and warning systems, the engine fire extinguishing system wiring and plumbing, the lower cargo compartment smoke/fire detection system, and the cargo compartment fire extinguishing system wiring and plumbing (Sections 1-4). The checks must be performed in accordance with specific Boeing Telex and FAA AD documents, dated between 31 January and 13 February 1989. Operators of Boeing 767 series aircraft are required to comply with the AD by performing the necessary functional checks within 25 days from 28 December 1989, and before the next flight following any maintenance actions involving engine overheat, fire detection, or fire extinguishing systems that could result in cross-connection or mis-connection of any system wiring or plumbing (Compliance). If the required checks have already been completed in accordance with previous Boeing Telex or FAA AD documents, they are considered to meet the current requirements. Failure to comply with the AD/B767/22 Amendment 2 may result in potential safety hazards, including engine fires or smoke in the cargo compartment, which could compromise the safety of the aircraft and its occupants. While the Civil Aviation Regulations 1998 do not explicitly state specific penalties for non-compliance, breaches of airworthiness directives can lead to enforcement actions by the Civil Aviation Safety Authority (CASA). These actions may include fines, suspension or revocation of air operator certificates, and potential criminal charges for individuals responsible for non-compliance, depending on the severity of the breach and any resulting harm.
