AD/BEECH 77/13 - Engine Control Rod Safety Washers

Overview

The Civil Aviation Regulations 1998, as amended and detailed in the legislative instrument F2006B04189, were enacted to ensure the safety and efficiency of civil aviation in Australia. This specific regulation, part of the broader Civil Aviation Safety Authority (CASA) framework, addresses the requirement for installing safety washers on the engine control rods of Beechcraft 77 (Skipper) Series aeroplanes. The regulation targets aircraft with serial numbers WA-1 to WA-312, mandating compliance with Beechcraft Service Instruction No. 1243 within 100 hours of time in service following 30 September 1983. The objective is to mitigate potential safety risks associated with the engine control rod ends, thereby enhancing the overall safety of air travel. The regulation was enacted by the Australian Government to ensure adherence to stringent safety standards set by CASA.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39-105, applies to the Beechcraft 77 (Skipper) series aeroplanes, particularly those with serial numbers WA-1 to WA-312. This legislative instrument mandates compliance with Beechcraft Service Instruction No. 1243, which concerns the installation of safety washers on the engine control rod ends. The directive is to be implemented within 100 hours of time in service following 30 September 1983. This regulation is designed to enhance the safety of the specified aircraft models by ensuring that critical components are maintained to the manufacturer’s standards, thereby preventing potential mechanical failures and enhancing overall airworthiness. The scope of this legislation is confined to the specified aeroplane models, ensuring that only these aircraft are subject to the requirements outlined in the directive.

Key Provisions

The Civil Aviation Regulations 1998, specifically Part 39 - 105, detail the Airworthiness Directives (AD) concerning various aircraft, including the Beechcraft 77 (Skipper) Series Aeroplanes. This part includes AD/BEECH 77/13, which pertains to engine control rod safety washers for models 77 (Skipper) with serial numbers WA-1 to WA-312. According to section 39-105, this directive requires adherence to Beechcraft Service Instruction (SI) No. 1243, which outlines the necessary safety measures for the specified aircraft models. Section 39-105 mandates that the safety washers must be installed within 100 hours of the aircraft's time in service following 30 September 1983. This requirement is a direct response to the manufacturer's recommendation to enhance safety by installing these washers at the engine control rod ends. The directive ensures that all affected aircraft comply with these safety standards to mitigate potential risks associated with the engine control system. Compliance with AD/BEECH 77/13 imposes specific obligations on aircraft operators and owners. They must ensure that the safety washers are installed by qualified personnel, as per the instructions provided in Beechcraft SI No. 1243. Additionally, operators are required to document the installation process and maintain records of compliance, ensuring that the aircraft remains airworthy and meets the regulatory standards set forth by the Civil Aviation Safety Authority (CASA). Failure to comply with the directives outlined in section 39-105 can result in significant consequences. The regulations stipulate that non-compliance may lead to enforcement actions by CASA. This can include fines, penalties, or even grounding of the aircraft until the necessary actions are taken. The specific penalties are not detailed within this legislative instrument, but generally, non-compliance with airworthiness directives can lead to severe civil and criminal consequences, including substantial fines and imprisonment for serious breaches.
