Overview

The Civil Aviation Regulations 1998, as amended, form the legislative framework governing civil aviation safety in Australia, and are enforced by the Civil Aviation Safety Authority (CASA). One of the key legislative instruments under this framework is the AD/B727/79, which pertains to Boeing 727 Series Aeroplanes. Enacted in 1998, the Civil Aviation Regulations were introduced to establish a comprehensive set of safety standards and requirements for civil aviation in Australia, with the overarching objective of ensuring the safety of the public and promoting efficient and safe air transport. AD/B727/79 specifically addresses the modification of static sensing holes on model B727-100 and -200 aircraft, ensuring that these aircraft comply with safety directives within a specified timeframe to mitigate any risks associated with the static sensing holes of.047 inch diameter. Compliance with this directive is mandatory within 3000 hours of time in service after 30 June 1977, in alignment with either the FAA AD 77-02-02 or Boeing SB No. 727-34-94.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, establish the requirements for the airworthiness directives concerning Boeing 727 Series aeroplanes. This legislation applies to all model B727-100 and -200 aircraft equipped with static sensing holes of a 0.047-inch diameter. The directive mandates compliance within 3000 hours of time in service following 30 June 1977, referencing either the FAA AD 77-02-02 or Boeing SB No. 727-34-94 document. This regulation is designed to ensure the safety of aircraft operations by addressing specific technical modifications. The application of these regulations is overseen by the Civil Aviation Safety Authority, enforcing compliance across all relevant operators within Australia’s jurisdiction. While the regulation focuses on specific aircraft types and modifications, it does not explicitly state exclusions or exemptions, implying a broad application unless otherwise specified through subordinate instruments.

Key Provisions

The Civil Aviation Regulations 1998, particularly in Part 39 - 105, includes an Airworthiness Directive (AD) targeting Boeing 727 series aeroplanes. Specifically, AD/B727/79 focuses on the modification of static sensing holes on model B727-100 and -200 aircraft (Section 1). This AD applies to all such aircraft that have static sensing holes with a diameter of 0.047 inches (Section 2). Compliance with this directive is mandated through adherence to either the Federal Aviation Administration (FAA) AD 77-02-02 or Boeing Service Bulletin No. 727-34-94 (Section 3). The directive stipulates that the required modifications must be completed within 3000 hours of time in service after 30 June 1977 (Section 4). Under this legislation, the primary obligation for aircraft operators is to ensure that the specified modifications to the static sensing holes are carried out within the prescribed timeframe. This involves either following the FAA AD 77-02-02 or Boeing SB No. 727-34-94, whichever is applicable. The modifications are intended to enhance the safety and airworthiness of the aircraft by addressing potential issues associated with the original static sensing hole design. Operators must verify that these modifications are documented and that the aircraft meets all specified requirements before continuing operations beyond the 3000-hour threshold. Failure to comply with the provisions outlined in AD/B727/79 can lead to significant legal consequences. Operators who do not complete the required modifications within the stipulated timeframe may face penalties under the Civil Aviation Act 1988. The severity of the consequences depends on the extent of the non-compliance and any resultant safety risks. Although specific penalties are not detailed in the AD itself, non-compliance with airworthiness directives generally can result in fines, operational restrictions, or other enforcement actions by the Civil Aviation Safety Authority (CASA). In extreme cases, continued operation of a non-compliant aircraft may lead to more severe penalties, including potential grounding of the aircraft or even prosecution under aviation safety laws.
