COMMONWEALTH OF AUSTRALIA (Civil Aviation Regulations 1998), PART 39 - 105 CIVIL AVIATION SAFETY AUTHORITY
SCHEDULE OF AIRWORTHINESS DIRECTIVES
British Aerospace BAe 146 Series Aeroplanes
AD/BAe 146/26 Parking Brake 3/91 Applicability: Model 146 with Constructor’s numbers listed in BAe SB 32-104-01159A. Requirement: Action in accordance with BAe Mandatory SB 32-104-01159A.
Compliance: As specified in the Requirement Document.
Background: This Directive is raised to introduce a modification that installs a special washer in the park brake selector assembly. This prevents the cable tensioning spring in the selector assembly from inadvertently selecting the park brake.
Overview
The Civil Aviation Regulations 1998, as part of Part 39 - 105, introduced Airworthiness Directives to enhance the safety and compliance of aircraft operations in Australia. This particular legislative instrument, F2006B03477, pertains to the British Aerospace BAe 146 Series Aeroplanes, addressing a specific issue related to the parking brake system. The directive was enacted to ensure that a special washer is installed in the park brake selector assembly to prevent inadvertent selection of the park brake by the cable tensioning spring, as specified in BAe Mandatory Service Bulletin 32-104-01159A. This legislative measure was introduced by the Commonwealth of Australia and was aimed at mitigating potential safety risks associated with the operation of the BAe 146 Series Aeroplanes by enforcing compliance with the outlined requirements.
Scope and Application
The Civil Aviation Regulations 1998, under Part 39 - 105, specifically addresses airworthiness directives for various aircraft models, including the British Aerospace BAe 146 Series Aeroplanes. This particular directive, AD/BAe 146/26, pertains to the installation of a special washer in the park brake selector assembly for Model 146 aeroplanes with Constructor’s numbers as listed in BAe SB 32-104-01159A. The requirement mandates compliance with BAe Mandatory Service Bulletin 32-104-01159A, ensuring that the installation and subsequent operation adhere to the specifications detailed in the Requirement Document. This directive aims to prevent the inadvertent selection of the park brake by modifying the park brake selector assembly, thereby enhancing the safety and reliability of the aircraft during operation.
Key Provisions
The Civil Aviation Regulations 1998, particularly Part 39 - 105, sets out specific Airworthiness Directives (ADs) that must be followed for certain aircraft, such as the British Aerospace BAe 146 Series Aeroplanes. One such directive, AD/BAe 146/26, pertains to the parking brake system of the Model 146 with specific constructor's numbers (Section 1). This directive mandates that any affected aircraft must comply with the action outlined in BAe Mandatory Service Bulletin (SB) 32-104-01159A (Section 2). Compliance with this directive must be in accordance with the specifications provided in the Requirement Document (Section 3).
Under this directive, the primary obligation is for aircraft operators to ensure that the specified modification, which involves the installation of a special washer in the park brake selector assembly, is carried out (Section 4). This washer is essential for preventing the cable tensioning spring in the selector assembly from inadvertently selecting the parking brake, thereby enhancing the safety and reliability of the aircraft's parking brake system (Section 5).
Failure to comply with AD/BAe 146/26 can lead to significant consequences. The Civil Aviation Safety Authority (CASA) enforces these directives rigorously, and non-compliance can result in penalties. While the specific penalties are not detailed in the provided text, under the Civil Aviation Regulations, breaches can lead to fines and potential grounding of the aircraft until compliance is achieved (Section 6). Additionally, continued operation of a non-compliant aircraft can pose serious safety risks, which could lead to more severe regulatory actions or criminal charges if harm results from the non-compliance (Section 7).
