Overview

The Civil Aviation Regulations 1998, introduced by the Australian Government, were enacted to ensure the safety and efficiency of civil aviation within Australia. Specifically, Part 39 - 105 of these regulations deals with airworthiness directives, which are legally enforceable rules related to the design, production, maintenance, and operation of aircraft. The problem these regulations address is the need for stringent safety standards to prevent accidents and ensure the reliability of aircraft operations. The policy objective is to safeguard the public and promote the safe, efficient, and environmentally sustainable operation of civil aviation. These regulations are administered by the Civil Aviation Safety Authority (CASA), which is the regulatory body responsible for ensuring compliance with civil aviation safety standards in Australia.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, applies to the airworthiness directives concerning Beechcraft 55, 58 and 95-55 (Baron) Series Aeroplanes. This regulation is relevant to specific models and serial numbers of these aircraft, mandating compliance with the prescribed actions to ensure safety. The directive is applicable to the 58P and 58PA models with serial numbers ranging from TJ-46 to TJ-74, TJ-76, TJ-78 to TJ-80, TJ-82 to TJ-85, TJ-88, and TJ-89, and similarly to the 58TC and 58TCA models with serial numbers TK-7 to TK-18, TK-20, TK-21, TK-25, TK-27, TK-30, TK-32, TK-34, TK-37, and TK-38. The requirement necessitates compliance with Beechcraft Service Instruction No. 0875-038, to be executed within 100 hours of the aircraft's time in service after 31 March 1977. This directive is issued by the Civil Aviation Safety Authority (CASA) to maintain the safety standards of these particular aircraft within the Commonwealth of Australia.

Key Provisions

The Civil Aviation Regulations 1998, particularly Part 39 - 105, introduces a specific Airworthiness Directive (AD) for Beechcraft 55, 58, and 95-55 (Baron) Series Aeroplanes, focusing on the engine mount fitting attach bolts. This directive, AD/BEECH 55/49, mandates actions for certain models and serial numbers, as outlined in the legislation (Part 39 - 105). The directive requires compliance with Beechcraft Service Instruction No. 0875-038, which details the specific actions needed for the affected aircraft. The AD applies to specific Beechcraft 58P and 58PA models with serial numbers ranging from TJ-46 to TJ-74, TJ-76, TJ-78 to TJ-80, TJ-82 to TJ-85, TJ-88, and TJ-89. It also applies to Beechcraft 58TC and 58TCA models with serial numbers TK-7 to TK-18, TK-20, TK-21, TK-25, TK-27, TK-30, TK-32, TK-34, TK-37, and TK-38 (Part 39 - 105). The requirement is for these aircraft to adhere to the actions specified in Beechcraft Service Instruction No. 0875-038, and this compliance must be achieved within 100 hours of time in service after 31 March 1977. Operators and owners of the specified Beechcraft models must ensure their aircraft meet the requirements set forth in the AD. This includes reviewing the aircraft's serial number to determine applicability, reviewing and following the instructions in Beechcraft Service Instruction No. 0875-038, and ensuring that the compliance actions are completed within the stipulated timeframe of 100 hours’ time in service post 31 March 1977. Failure to comply with these directives can result in the aircraft being deemed non-airworthy, leading to potential grounding and legal consequences. Violations of the AD/BEECH 55/49 and failure to comply with the stipulated actions can result in significant penalties. The Civil Aviation Regulations 1998 impose strict obligations on aircraft operators and owners to adhere to such directives. Non-compliance may lead to enforcement actions by the Civil Aviation Safety Authority (CASA), including fines and potential criminal charges for serious breaches. The exact penalties can vary but may include substantial monetary fines and, in severe cases, imprisonment for those responsible for the non-compliance.
