AD/CESSNA 188/24 - Stub Wing Front and Rear Spars

Overview

The Civil Aviation Regulations 1998, enacted by the Australian Government, serve to regulate civil aviation safety and are enforced by the Civil Aviation Safety Authority (CASA). Specifically, Part 39 - 105 of these Regulations contains Airworthiness Directives that ensure the safety of aircraft, including the Cessna 188 (Agwagon) series aeroplanes. The directive AD/CESSNA 188/24 addresses structural integrity issues by requiring action in accordance with Rex Aviation Ltd. Tech. Memo No. TM- 46, Issue 3. This directive aims to ensure compliance within 100 hours of time in service after 31 October 1974, thereby addressing a critical safety concern for the specified aircraft models.

Scope and Application

The Civil Aviation Regulations 1998, specifically under Part 39, mandate the application of airworthiness directives for various aircraft types, including the Cessna 188 (Agwagon) Series Aeroplanes. These regulations apply universally to all models of the specified aircraft, necessitating compliance with the technical memorandum issued by Rex Aviation Ltd. The requirement involves action in accordance with Rex Aviation Ltd. Tech. Memo No. TM-46, Issue 3, which must be completed within 100 hours of time in service after 31 October 1974. This regulation is a Commonwealth requirement, thus extending its jurisdictional reach across the entirety of Australia. There are no stated exclusions or exemptions within the directive itself, though the broader regulations may include provisions for variances or waivers under specific circumstances. The detailed compliance instructions and the scope of the directive are further defined and potentially expanded upon through subordinate instruments, ensuring that the safety standards are uniformly applied across the aviation industry within Australia.

Key Provisions

The Civil Aviation Regulations 1998 (Part 39 - 105) contain the Civil Aviation Safety Authority's (CASA) Schedule of Airworthiness Directives, which include specific directives for various aircraft models, such as the Cessna 188 (Agwagon) Series Aeroplanes. One such directive is AD/CESSNA 188/24, which pertains to the stub wing front and rear spars. This directive, applicable to all models, requires action in accordance with Rex Aviation Ltd. Tech. Memo No. TM-46, Issue 3. The directive mandates compliance within 100 hours of time in service after 31 October 1974, ensuring that the aircraft's wing structures meet the specified technical standards. Under this legislation, the operators and owners of Cessna 188 (Agwagon) Series Aeroplanes are obligated to ensure that the aircraft's stub wing front and rear spars comply with the requirements set out in AD/CESSNA 188/24. This involves adhering to the technical memo issued by Rex Aviation Ltd., which provides detailed instructions and specifications for maintaining or modifying the wing spars to meet airworthiness standards. Operators must conduct the necessary inspections, repairs, or replacements within the stipulated timeframe to maintain the aircraft's airworthiness certificate and ensure the safety of the flight operations. Failure to comply with the provisions of AD/CESSNA 188/24 may result in significant legal consequences. The Civil Aviation Regulations 1998 impose penalties for non-compliance with airworthiness directives. In the case of AD/CESSNA 188/24, operators who fail to comply with the requirements may face civil penalties, which can include substantial fines. Additionally, continued operation of a non-compliant aircraft can lead to enforcement actions, such as the grounding of the aircraft until the necessary actions are taken. Such non-compliance not only jeopardises the safety of the aircraft but also poses potential risks to passengers and crew, thereby making adherence to these directives imperative.
