AD/HS 125/115 Amdt 1 - NLG Bay Sidewall

Overview

The Civil Aviation Regulations 1998, specifically Part 39 - 105, establishes the Civil Aviation Safety Authority Schedule of Airworthiness Directives, which includes regulations pertinent to various aircraft models, such as the British Aerospace BAe 125 Series Aeroplanes. This legislation was enacted to ensure the safety and airworthiness of aircraft operating in Australian airspace by implementing mandatory safety directives and standards. AD/HS 125/115 Amendment 1 addresses a specific issue identified with the nose landing gear sidewall of the BAe 125 Series Aeroplanes, particularly models up to and including series 800A and 800B, which had reported instances of cracks. The policy objective behind this directive is to maintain and enhance the safety standards of aircraft operations by mandating specific actions to address these structural concerns, as outlined in the Mandatory BAe 125 Service Bulletin 53-73 Revision 2. Compliance with these directives is crucial to ensure the ongoing airworthiness of the affected aircraft.

Scope and Application

The Civil Aviation Regulations 1998, specifically under Part 39 - 105, mandate that the Civil Aviation Safety Authority’s Schedule of Airworthiness Directives applies to all British Aerospace BAe 125 Series aeroplanes, up to and including series 800A and 800B. This regulation targets aircraft operators, maintenance personnel, and any entity involved in the operation or upkeep of these specific aircraft models, ensuring they adhere to stringent safety protocols to mitigate the risk of nose landing gear sidewall cracks. The directive extends its jurisdictional reach across the Commonwealth of Australia, imposing a requirement for compliance with the Mandatory BAe 125 Service Bulletin 53-73 Revision 2, which outlines the specific actions and inspections necessary to maintain airworthiness. This directive is a response to reported incidents of cracks in the nose landing gear sidewall, and it mandates that all affected aircraft must undergo the revised inspection procedures specified in the Requirement Document. The Civil Aviation Regulations 1998 do not explicitly exclude any entities or persons from this directive's applicability, nor do they specify particular thresholds that might exempt certain aircraft from compliance. However, the scope of the directive can be extended or refined through subordinate instruments issued by the Civil Aviation Safety Authority. These additional instruments may further detail procedural requirements or specify additional conditions under which the directive applies, ensuring that all stakeholders remain informed and compliant with the evolving safety standards.

Key Provisions

The key operative sections of the Civil Aviation Regulations 1998, as applied to the British Aerospace BAe 125 Series Aeroplanes, are found in Part 39, specifically under Schedule of Airworthiness Directives. Section 39-105 details the airworthiness directive (AD) for the BAe 125 series aeroplanes, with Amendment 1 (AD/HS 125/115 Amdt 1) focusing on the NLG Bay Sidewall. This section mandates compliance with the specific requirements outlined in the directive, which is applicable to all models 125 up to and including series 800A and 800B. The primary requirement (Section 39-105) is that action must be taken in accordance with the Mandatory BAe 125 Service Bulletin 53-73 Revision 2. This action involves addressing reported cracks in the nose landing gear sidewall. Compliance with this directive necessitates adherence to the specific instructions and procedures detailed in the Requirement Document, ensuring that the inspection area is properly examined and any additional checks are performed as specified. The obligations imposed by this legislation on the relevant parties, such as aircraft operators and maintenance personnel, are to conduct thorough inspections of the nose landing gear sidewall as per the updated inspection criteria in the Requirement Document. This includes identifying and rectifying any cracks or damage to ensure the continued airworthiness of the aircraft. Operators must also ensure that all maintenance and inspection activities are performed by qualified personnel and that records of these activities are kept in accordance with regulatory requirements. Failure to comply with the provisions of this airworthiness directive can result in severe consequences. While the specific penalties are not detailed in the text, non-compliance with Civil Aviation Regulations can generally lead to significant civil or criminal penalties. These can include fines, suspension or revocation of aircraft operation permits, and potential criminal charges if the non-compliance results in safety incidents. The severity of the penalties reflects the critical nature of maintaining airworthiness standards to ensure the safety of passengers and crew.
