AD/B767/17 - Entry and Service door Mid Liner Dust Covers

Overview

The Civil Aviation Regulations 1998, specifically PART 39 - 105, was enacted to establish and maintain airworthiness directives to ensure the safe operation of civil aircraft in Australian airspace. This regulatory framework was introduced to address safety concerns and compliance issues that could potentially compromise the integrity and safety of aircraft in service. The Civil Aviation Safety Authority, under the authority of the Commonwealth of Australia, is responsible for overseeing the implementation and enforcement of these regulations, with the overarching policy objective of maintaining the highest standards of aviation safety. One such directive, AD/B767/17, pertains to the Boeing 767 Series Aeroplanes, requiring the modification of entry and service door mid liner dust covers to prevent issues caused by a loose inner window interfering with the door operation. This directive mandates inspections at intervals not exceeding 90 days and requires modifications to be completed before a specified date, reflecting the authority's commitment to proactive safety measures.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, issued under the authority of the Civil Aviation Safety Authority, mandates the adherence of all Boeing 767 series aeroplanes to Airworthiness Directive AD/B767/17 concerning the Entry and Service door Mid Liner Dust Covers. This regulation applies to all model 767 aircraft detailed in the accompanying requirement document, demanding compliance with Boeing Service Bulletin 767-25A0092, which references FAA AD 87-25-09. The directive necessitates inspections at intervals not exceeding 90 days and mandates that modifications be completed prior to 19 June 1989 to prevent the issue of a loose inner window interfering with the door's operation and hindering the door from fully opening. The regulation is applicable on a national level and is enforced across all states and territories within Australia, ensuring consistent safety standards in civil aviation. The scope of the regulation is not limited by specific exclusions or exemptions, though the application may be refined through subordinate instruments issued by the Civil Aviation Safety Authority.

Key Provisions

The Civil Aviation Regulations 1998, specifically Part 39 - 105, includes Airworthiness Directives (ADs) that are crucial for maintaining the safety of aircraft operations. In this context, AD/B767/17 pertains to Boeing 767 series aeroplanes and focuses on the entry and service door mid liner dust covers (section 3/88). This directive mandates that all affected aircraft models must adhere to the actions outlined in Boeing Service Bulletin 767-25-A0092. For further reference, FAA AD 87-25-09 is also noted, indicating alignment with international safety standards. The main requirement of this directive is to inspect the mid liner dust covers at intervals not exceeding 90 days until the necessary modifications are made. The modification must be completed before 19 June 1989. This action is critical as a loose inner window (dust cover) can interfere with the movement of the upper liner, potentially preventing the door from opening fully. This could compromise the safety and functionality of the aircraft. Compliance with AD/B767/17 imposes several obligations on the parties involved. Aircraft operators must ensure that the inspections and modifications are carried out according to the specified timeline and procedures. This involves regular checks to identify any issues with the mid liner dust covers and timely implementation of the modifications as recommended by Boeing. Furthermore, operators must maintain accurate records of these inspections and modifications to demonstrate compliance with the directive. Failure to comply with the requirements of AD/B767/17 can result in serious consequences. While the specific civil or criminal penalties are not detailed in the provided text, non-compliance with airworthiness directives generally can lead to severe repercussions. These may include fines, grounding of the aircraft, and potential criminal charges for individuals or entities responsible for ensuring compliance. The seriousness of these penalties underscores the importance of adhering to the safety regulations outlined in the Civil Aviation Regulations 1998.
