AD/BAe 146/34 - Anti-Skid Control System

Overview

The Civil Aviation Regulations 1998, which were enacted by the Parliament of the Commonwealth of Australia, constitute the regulatory framework governing civil aviation safety within the country. Among the various provisions within these regulations, Part 39 specifically addresses the airworthiness directives essential for maintaining aircraft safety. One such directive, AD/BAe 146/34, pertains to the British Aerospace BAe 146 Series Aeroplanes and specifically mandates compliance with anti-skid control system modifications. This directive was introduced to address the problem of potential braking system failures due to incorrect operation of the Anti Skid Control Box, a risk highlighted by reported incidents of loss of normal braking. The directive mandates adherence to British Aerospace Service Bulletin SB 32-124-70491A&B, which includes necessary modifications to the Anti Skid Control Boxes, a requirement classified as mandatory by the UK Civil Aviation Authority. The overarching policy objective is to ensure the continued safety and reliability of civil aviation operations by addressing critical mechanical failures proactively.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, applies to the maintenance and operation of British Aerospace BAe 146 Series aeroplanes within the Commonwealth of Australia. The regulations are administered by the Civil Aviation Safety Authority (CASA) and pertain to the airworthiness directives concerning the anti-skid control system of the BAe 146 aircraft series. These regulations apply to all operators and maintainers of BAe 146 aeroplanes within Australia, ensuring compliance with the specified directives to mitigate risks associated with potential failures in the anti-skid control system. The regulations mandate that the actions required by British Aerospace Service Bulletin (SB) 32-124-70491A&B must be followed, including modifications to the anti-skid control boxes held as spares, as classified mandatory by the UK Civil Aviation Authority (CAA). Compliance with these directives is mandatory for all BAe 146 aeroplanes that were manufactured prior to 30 June 1992. The legislation does not specify exclusions or exemptions, and its application is enforced through the issuance of airworthiness directives by CASA, with adherence overseen through regular inspections and audits.

Key Provisions

The Civil Aviation Regulations 1998, specifically in Part 39 - 105, pertain to the Civil Aviation Safety Authority's (CASA) Schedule of Airworthiness Directives for British Aerospace BAe 146 Series Aeroplanes. Section 39 - 105 AD/BAe 146/34 mandates the compliance with the Anti-Skid Control System directive. This directive is applicable as specified in the Requirement Document, and it mandates that actions be taken in accordance with BAe Service Bulletin 32-124-70491A&B. It is noted that the UK Civil Aviation Authority (CAA) classifies compliance with this service bulletin as mandatory, including the mandatory modification of Anti Skid Control Boxes that are held as spares. The directive requires compliance prior to 30 June 1992. The obligations imposed by this legislation are significant for operators of the British Aerospace BAe 146 Series Aeroplanes. Operators are required to adhere strictly to the Service Bulletin 32-124-70491A&B, which includes specific modifications to the Anti Skid Control Boxes. This ensures that these spares are modified to prevent any potential failure that could lead to a loss of normal braking capabilities. Operators must ensure that any Anti Skid Control Boxes held as spares are modified in accordance with the UK CAA's requirements, and that all modifications are completed before the specified deadline of 30 June 1992. Failure to comply with the provisions set out in the Civil Aviation Regulations 1998 could result in serious consequences. Non-compliance with the Anti-Skid Control System directive could potentially lead to safety issues, including the risk of a loss of normal braking, which could compromise the safety of the aircraft and its occupants. Under the legislation, non-compliance could be treated as an offence. While specific penalties are not detailed within the provided text, it can be inferred that penalties for non-compliance with aviation safety directives can be severe, potentially including hefty fines, suspension or revocation of aircraft operating certificates, and other regulatory actions that could affect the operational viability of the aircraft.
