COMMONWEALTH OF AUSTRALIA (Civil Aviation Regulations 1998), PART 39 - 105 CIVIL AVIATION SAFETY AUTHORITY
SCHEDULE OF AIRWORTHINESS DIRECTIVES
Boeing 747 Series Aeroplanes
AD/B747/87 Aural and Master Fire Warning Systems 3/91
Applicability: All model 747-400 series aeroplanes listed in the Requirement Document. Requirement: Action in accordance with the technical requirements of FAA AD 90-26-08.
Note: Boeing Alert SB 747-26A2171 also refers.
Compliance: As specified in the Requirement Document with an effective date of 21 March 1991. Background: Reports indicate that with certain Integrated Display System (IDS) software installed,
the aural and master caution systems of the fire detection system are inoperative.
This failure cannot be identified during normal system checks, and if not corrected, could result in the failure of the system to annunciate a fire in the APU, engines, wheel wells or cargo compartments.
Overview
The Civil Aviation Regulations 1998 (Cth) are a comprehensive set of regulations enacted by the Australian Parliament, governing all aspects of civil aviation within Australia. This legislative instrument, particularly PART 39 - 105 CIVIL AVIATION SAFETY AUTHORITYSCHEDULE OF AIRWORTHINESS DIRECTIVES, was introduced to ensure the safety and airworthiness of aircraft operating in Australian airspace. The specific directive AD/B747/87, dated 3 March 1991, targets Boeing 747 Series aeroplanes, aiming to address issues with the aural and master fire warning systems. This directive was implemented to rectify a problem where the fire detection system's aural and master caution systems could become inoperative with certain Integrated Display System (IDS) software installed. If left unaddressed, this issue could result in the failure to detect and warn of fires in critical areas such as the Auxiliary Power Unit (APU), engines, wheel wells, or cargo compartments, thereby posing significant safety risks.
The policy objective behind these regulations is to maintain the highest standards of aviation safety by ensuring that all aircraft meet stringent airworthiness requirements. This is achieved through detailed directives that mandate specific actions to be taken by aircraft operators, ensuring that identified safety issues are promptly and effectively addressed. The directive for the Boeing 747 Series aeroplanes underscores the commitment to continuous safety improvements and the proactive measures taken to mitigate potential hazards in civil aviation.
Scope and Application
The Civil Aviation Regulations 1998, specifically PART 39 - 105, issued by the Civil Aviation Safety Authority, pertain to airworthiness directives concerning Boeing 747 Series aeroplanes. This particular legislative instrument, AD/B747/87, focuses on the aural and master fire warning systems of all model 747-400 series aeroplanes. The directive applies to all aircraft within the specified model series, mandating compliance with the technical requirements of FAA AD 90-26-08. This compliance ensures the aircraft meet safety standards by addressing inoperative aural and master caution systems when certain Integrated Display System (IDS) software is installed. Failure to adhere to these directives could result in undetected fire-related failures, thereby compromising safety. The directive is effective as of 21 March 1991, and Boeing Alert SB 747-26A2171 also references relevant information regarding the issue.
Key Provisions
The Civil Aviation Regulations 1998, specifically Part 39, Section 105, addresses the Airworthiness Directives for Boeing 747 Series Aeroplanes, detailing the technical requirements for maintaining safe operational standards. For the Boeing 747-400 series aeroplanes, AD/B747/87 mandates action concerning the aural and master fire warning systems (Section 3/91). This directive requires operators to comply with the technical specifications outlined in FAA AD 90-26-08, and additionally, Boeing Alert SB 747-26A2171 may be referenced for further guidance. Compliance with these directives must be achieved as specified in the Requirement Document, with an effective date of 21 March 1991.
The obligations imposed on the parties governed by this Act include ensuring that the aural and master fire warning systems on Boeing 747-400 series aeroplanes are operational and correctly configured. Operators must adhere to the technical requirements set forth by FAA AD 90-26-08, which may involve inspections, modifications, or replacements of system components to address the identified inoperability issues. Additionally, operators must keep abreast of any updates or changes to the directives as specified in the Requirement Document and Boeing Alert SB 747-26A2171. Failure to comply with these directives can lead to significant safety risks, as the fire detection system may fail to announce a fire in critical areas such as the Auxiliary Power Unit (APU), engines, wheel wells, or cargo compartments, which could have dire consequences during flight.
Failure to comply with the requirements set forth in AD/B747/87 can result in severe consequences. Section 3/91 outlines the potential for non-compliance to lead to serious safety deficiencies. Civil Aviation Safety Authority (CASA) may take enforcement action against operators who do not meet these requirements. The potential penalties for non-compliance include fines, which can be substantial, as well as other regulatory actions such as grounding of the aircraft until compliance is achieved. In extreme cases, failure to address these safety directives can lead to criminal charges, especially if negligence results in accidents or loss of life. The specific penalties for breaches are not detailed in the provided text but generally, severe penalties are imposed to ensure the highest safety standards are maintained.
