AD/B767/65 - Bulk Cargo Ventilation Valve

Overview

The Civil Aviation Regulations 1998, as amended, are fundamental in regulating and ensuring the safety and efficiency of civil aviation within Australia. Specifically, Part 39 - 105 under the Civil Aviation Safety Authority's Schedule of Airworthiness Directives addresses the safety of Boeing 767 Series aeroplanes. This legislative instrument, issued by the Civil Aviation Safety Authority, was enacted to address a safety concern regarding the bulk cargo ventilation system of the Boeing 767 Series. The problem it sought to resolve was the potential for the bulk cargo ventilation flapper valve to fail to close properly, leading to the risk of loss of extinguishing agent and subsequent fire hazards. The directive mandates the removal of the bulk cargo ventilation flapper valve in compliance with Boeing Alert SB 767-21A0098, with the objective of enhancing aviation safety by mitigating the risk of fire in the cargo compartment. The compliance requirement is set within 4000 hours of time in service after 2 March 1992, aligning with international safety standards set by the Federal Aviation Administration (FAA).

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, applies to the Boeing 767 Series aeroplanes, as detailed in the Schedule of Airworthiness Directives. The regulations mandate the removal of the bulk cargo ventilation flapper valve in compliance with Boeing Alert SB 767-21A0098, with reference to FAA AD 92-02-12 Amendment 39-8148. The requirement necessitates compliance within 4000 hours of time in service after 2 March 1992, aimed at addressing a reported incident where a cargo compartment flapper valve failed to close during a functional check of the bulk cargo compartment fire extinguishing system. This could potentially lead to the loss of extinguishing agent through an open flapper valve. The regulations are enforced by the Civil Aviation Safety Authority (CASA), ensuring that the specified modifications are implemented to maintain the safety standards of aircraft operations across Australia.

Key Provisions

The Civil Aviation Regulations 1998, particularly Part 39 - 105 concerning Airworthiness Directives, includes provisions for ensuring the safety and airworthiness of aircraft in Australian airspace. Specifically, the Boeing 767 Series Aeroplanes are subject to Airworthiness Directive AD/B767/65, which mandates actions related to the bulk cargo ventilation valve (Section 1). This directive requires the removal of the bulk cargo ventilation flapper valve in accordance with Boeing Alert Service Bulletin SB 767-21A0098, referencing FAA AD 92-02-12 Amendment 39-8148 (Section 2). The directive applies to the Model 767 Series as specified in the Requirement Document and mandates compliance within 4000 hours of time in service after 2 March 1992 (Section 3). The obligations imposed by this directive on the parties and entities it governs are clear and specific. Operators and maintenance providers of Boeing 767 aircraft must ensure that the bulk cargo ventilation flapper valve is removed and replaced or otherwise dealt with as per the Boeing Alert Service Bulletin SB 767-21A0098. This requirement aims to prevent the risk of the flapper valve not closing during functional checks, which could lead to a loss of extinguishing agent in the cargo compartment, thereby compromising the safety of the aircraft (Section 4). Non-compliance with the AD/B767/65 directive can lead to significant legal and operational consequences. Under the Civil Aviation Act 1988, failure to adhere to Airworthiness Directives can result in enforcement actions by the Civil Aviation Safety Authority (CASA). Depending on the severity and circumstances of the breach, penalties may include substantial fines, suspension or revocation of an operator's certificate, and potential criminal charges against individuals or corporate entities responsible for the non-compliance. The specific penalties are determined by CASA and can vary based on the nature and extent of the violation, but they are designed to ensure that safety standards are strictly maintained within the aviation industry (Section 5).
