Overview

The Civil Aviation Regulations 1998, under Part 39 - 105, incorporate the Civil Aviation Safety Authority Schedule of Airworthiness Directives, specifically addressing Boeing 747 Series Aeroplanes. Enacted by the Australian Government, this legislation was introduced to address the safety concerns associated with the deployment of off-wing slides on the Boeing 747, particularly those equipped with B.F. Goodrich slides. The directive aims to ensure that the mechanical restraints of the slides are modified to enhance their reliability, thereby minimising the risk of deployment failures during emergency evacuations. This legislative instrument reflects the commitment to maintaining the highest safety standards in civil aviation, aligning with international safety protocols set forth by the Federal Aviation Administration (FAA) and other relevant authorities. The policy objective behind this legislation is to mandate specific modifications to the mechanical restraints of off-wing slides on Boeing 747 aeroplanes to prevent deployment failures. By referencing FAA AD 80-25-03, Amendment 39-3982, and B.F. Goodrich SB No. 25-054, the directive ensures that operators comply with internationally recognised safety requirements. This legislative measure was enacted to protect the safety of passengers and crew by ensuring that the mechanical restraints of the slides are reliable and function correctly during emergency situations.

Scope and Application

The Civil Aviation Safety Authority Schedule of Airworthiness Directives under the Civil Aviation Regulations 1998 applies specifically to all models of Boeing 747 aircraft that are equipped with B.F. Goodrich off-wing slides. This directive mandates the modification of mechanical restraints on these slides to ensure the reliability and safety of the deployment mechanism. The applicability of the directive is governed by the FAA AD 80-25-03, Amendment 39-3982, or the B.F. Goodrich SB No. 25-054, both of which outline the specific requirements and procedures for compliance. The modifications to the shear pin mechanical restraints aim to enhance the reliability of the slide deployment system, which is crucial for ensuring passenger safety in emergency situations. Compliance with these directives is mandatory for all affected aircraft within the Commonwealth of Australia, with the Civil Aviation Safety Authority overseeing adherence to the specified standards. There are no stated exclusions or exemptions within the scope of this directive, and compliance is enforced across the entire national jurisdiction.

Key Provisions

The Civil Aviation Regulations 1998, specifically Part 39 - 105, includes a Schedule of Airworthiness Directives (AD) for Boeing 747 series aeroplanes, which mandates modifications to the off-wing slides mechanical restraints (Section 39 - 105). This directive applies to all Boeing 747 models equipped with B.F. Goodrich off-wing slides. The requirement is to follow either FAA AD 80-25-03, Amendment 39-3982, or B.F. Goodrich Service Bulletin No. 25-054 (Section 39 - 105). Compliance with these directives is necessary to ensure the modified shear pin mechanical restraints are installed, thereby enhancing the reliability of the slide deployment system. Entities governed by these regulations, such as aircraft operators and maintenance organisations, must adhere to the specified modifications to the off-wing slides mechanical restraints. This includes ensuring that the shear pin mechanical restraints are modified as per the FAA or B.F. Goodrich requirements. Operators must keep accurate records of compliance and ensure that any modifications are completed by authorised personnel. Maintenance organisations must ensure that their technicians are trained and certified to perform these modifications. Failure to comply with the airworthiness directive can result in serious safety implications, as the off-wing slides are a critical emergency evacuation system. The regulations do not explicitly state penalties for non-compliance, but they do indicate that non-compliance can lead to serious safety risks. The Civil Aviation Safety Authority (CASA) can take enforcement action against operators and maintenance organisations that fail to comply with the AD, which may include grounding of the aircraft until compliance is achieved, fines, or other regulatory sanctions. The severity of the consequences depends on the extent of non-compliance and the impact on aviation safety.
