AD/SC7/3 - Flap - Aileron Shroud Attach Lugs - Modification

Overview

The Civil Aviation Regulations 1998 (Cth) were enacted to ensure the safety and efficiency of civil aviation within Australia. This legislative framework was introduced to address the need for a comprehensive regulatory system that governs all aspects of civil aviation, including the maintenance and operation of aircraft, to safeguard public safety and maintain a high standard of airworthiness. The Regulations were enacted by the Australian Parliament, reflecting a policy objective to provide robust safety standards and regulatory oversight to mitigate the inherent risks associated with aviation activities. One specific aspect of these Regulations is Part 39, which includes the 105 Civil Aviation Safety Authority Schedule of Airworthiness Directives. This particular legislative instrument, AD/SC7/3, pertains to the modification of flap-aileron shroud attach lugs for Short SC7 (Skyvan) Series Aeroplanes, aiming to ensure that these aircraft continue to meet required safety standards. The directive was introduced to address specific safety concerns identified in the operation of these aircraft, mandating compliance within a specified timeframe to maintain airworthiness and ensure the safety of all passengers and crew.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105 concerning the Civil Aviation Safety Authority Schedule of Airworthiness Directives, applies to all models of the Short SC7 (Skyvan) Series 3 aeroplanes. This legislation mandates compliance with AD/SC7/3, which pertains to the modification of flap - aileron shroud attach lugs. The directive requires compliance within 100 hours of time in service following 23 January 1970, as documented in Short SB No. 57-51. The regulations are applicable to these particular aircraft models within the Commonwealth of Australia, overseen by the Civil Aviation Safety Authority, ensuring adherence to safety standards mandated by this legislation. The scope of this directive is strictly limited to the specified aeroplanes, and no exclusions or exemptions are stated within the text provided. The application of these regulations may be extended or further defined through subordinate instruments, which may offer additional clarifications or detailed procedural guidelines.

Key Provisions

The Civil Aviation Regulations 1998, particularly under Part 39 - 105, outline specific requirements for ensuring the airworthiness of certain aircraft models. One such directive is AD/SC7/3, which pertains to Short SC7 (Skyvan) Series Aeroplanes (1). This directive addresses the modification of flap - aileron shroud attach lugs, as detailed in Short SB No. 57-51 (2). The directive applies to all models of Series 3 and mandates compliance within 100 hours of time in service after 23 January 1970 (3). Under this legislation, operators of Short SC7 (Skyvan) Series Aeroplanes are required to ensure that the modifications to the flap - aileron shroud attach lugs are completed as per the specifications outlined in Short SB No. 57-51. This involves inspecting the aircraft and ensuring that any deficiencies are rectified to meet the airworthiness standards set by the Civil Aviation Safety Authority (CASA) (4). Compliance with this directive is crucial to maintaining the safety and operational integrity of the aircraft (5). Failure to comply with the airworthiness directive AD/SC7/3 could result in serious consequences. The Civil Aviation Regulations 1998 impose obligations on operators to adhere to these directives to ensure the safety of the aircraft and its occupants (6). Non-compliance with the requirements of this directive could lead to enforcement actions by CASA, which may include penalties for breaches of airworthiness standards (7). While specific penalties are not detailed in the directive itself, the broader regulations provide for substantial fines and other civil or criminal consequences for non-compliance with aviation safety directives (8).
