AD/HS 125/52 - Flap Outer Hinge Assembly - Inspection

Overview

The Civil Aviation Regulations 1998, as part of Part 39 - 105, establish the Civil Aviation Safety Authority's (CASA) schedule of airworthiness directives, which are designed to address specific safety issues and ensure the continuing airworthiness of aircraft. One such directive is AD/HS 125/52, which pertains to the flap outer hinge assembly inspection of British Aerospace BAe 125 series aeroplanes. This directive was introduced to mitigate the risk of failure in the flap outer hinge assembly, which could potentially lead to severe in-flight incidents. The directive applies to all HS/DH/BH 125 series aeroplanes that have undergone modification 252670, as detailed in Hawker Siddeley SB No. 57-55. Compliance with this directive is mandatory and must be conducted in accordance with the specified requirement document to ensure safety and regulatory adherence.

Scope and Application

The Civil Aviation Regulations 1998, under Part 39 - 105, addresses the safety directives applicable to specific aircraft models, including the British Aerospace BAe 125 Series Aeroplanes. This particular legislative instrument, F2006B10491, mandates the inspection of the flap outer hinge assembly for all HS/DH/BH 125 series aeroplanes that have modification 252670 embodied, as detailed in Hawker Siddeley SB No. 57-55. Compliance with these regulations is necessary to ensure the continued airworthiness and safety of these aircraft, and must be carried out according to the specified requirement document. The regulations apply nationally, extending across all states and territories within Australia, ensuring a uniform standard of safety for civil aviation operations. There are no stated exclusions or exemptions in this particular directive, and it is enforced through the Civil Aviation Safety Authority, which may extend or restrict application through subordinate instruments as necessary.

Key Provisions

The Civil Aviation Regulations 1998, particularly Part 39 - 105 (1), outlines the requirements for maintaining the airworthiness of aircraft, including specific directives for certain aircraft models. For British Aerospace BAe 125 Series Aeroplanes, the regulation mandates a specific inspection of the flap outer hinge assembly (AD/HS 125/52). This directive, effective as of 8/78, applies to all HS/DH/BH 125 series aeroplanes that have modification 252670 incorporated, as referenced in Hawker Siddeley SB No. 57-55. The compliance requirement necessitates following the specified procedures outlined in the document to ensure the safety and airworthiness of these aircraft. The Act imposes several obligations on the operators and maintainers of the affected aircraft. Operators must ensure that all inspections of the flap outer hinge assembly are conducted in accordance with the instructions provided in the relevant document (AD/HS 125/52). This includes the need for trained and qualified personnel to carry out these inspections and any necessary repairs or replacements. Furthermore, operators are required to maintain accurate records of all inspections and any work performed on the flap outer hinge assembly, as stipulated in the regulation (Part 39 - 105(2)). Failure to comply with the provisions of the Civil Aviation Regulations 1998, particularly the requirements set out in AD/HS 125/52, can result in serious consequences. Breaches of these regulations can be considered violations of civil aviation safety standards, potentially leading to enforcement actions by the Civil Aviation Safety Authority (CASA). The penalties for non-compliance may include fines, as well as potential criminal charges if the breach is found to have contributed to an aviation accident or incident. The maximum penalties for such offences can vary, but they are designed to ensure stringent adherence to safety standards to protect passengers and crew.
