Overview
The Civil Aviation Regulations 1998, specifically Part 39 - 105, which pertains to the Civil Aviation Safety Authority's Schedule of Airworthiness Directives, was enacted to ensure the safety of civil aviation operations in Australia. This legislative instrument, which includes the AD/CESSNA 400/87 directive concerning Cessna 400 Series Aeroplanes, addresses specific safety concerns identified in these aircraft models. The primary issue it was introduced to resolve is the enlargement and elongation of aileron yoke assembly attach holes and corresponding holes, which could compromise the structural integrity and performance of the aircraft. This directive was issued by the Civil Aviation Safety Authority, aiming to mandate inspections and modifications within a specified timeframe to mitigate these risks.
The enactment of these regulations by the Australian Parliament underscores the commitment to maintaining stringent safety standards within the civil aviation sector. The policy objective is to ensure that aircraft remain airworthy and safe for operation by addressing potential structural issues proactively. Compliance with these directives is mandatory for the specified Cessna models, requiring inspections and necessary modifications within 200 hours of time in service after the directive was issued on 30 April 1983.
Scope and Application
The Civil Aviation Regulations 1998, specifically Part 39 - 105 concerning the Civil Aviation Safety Authority's Schedule of Airworthiness Directives, applies to the inspection and modification of the aileron yoke mounting bracket attachment for specific models of Cessna 400 series aeroplanes. This regulation applies to all models 402C with serial numbers ranging from 402C0292 to 402C0528, all models 414A with serial numbers ranging from 414A0498 to 414A0680, all models 421C with serial numbers ranging from 421C0872 to 421C1115, and all models 425 with serial numbers ranging from 425-0002 to 425-0118, excluding serial numbers 425-0107 and 425-0112. This directive mandates compliance within 200 hours of time in service after April 30, 1983, addressing issues such as enlargement and elongation of the aileron yoke assembly attach holes and corresponding holes. The regulation is part of the broader framework established by the Civil Aviation Safety Authority to ensure the safety and airworthiness of aircraft operating within Australian airspace.
Key Provisions
The Civil Aviation Regulations 1998, specifically Part 39 - 105, which governs the Civil Aviation Safety Authority (CASA) Schedule of Airworthiness Directives, includes an important directive concerning the Cessna 400 series aeroplanes. This directive, identified as AD/CESSNA 400/87, pertains to the inspection and modification of the aileron yoke mounting bracket attachment for specific models. According to section (4/83), this directive applies to all models 402C with serial numbers (S/Nos.) ranging from 402C0292 to 402C0528, all models 414A with S/Nos. 414A0498 to 414A0680, all models 421C with S/Nos. 421C0872 to 421C1115, and all models 425 with S/Nos. 425-0002 to 425-0118, except for S/Nos. 425-0107 and 425-0112. The directive references two documents: Cessna Customer Care S.I.L. ME82-57 and Cessna Customer Care S.I.L. PJ82-42, which provide detailed information and guidance on the required modifications.
The obligations imposed by this directive are clear and specific. Aircraft operators and owners must ensure that the inspection and necessary modifications to the aileron yoke mounting bracket attachment are completed within 200 hours of time in service after 30 April 1983. This requirement is aimed at addressing the issue of enlargement and elongation of the aileron yoke assembly attach holes and corresponding holes, which has been detected in the specified aircraft models. Compliance with this directive is essential to maintain the airworthiness of the aircraft and ensure safe operation.
Failure to comply with the AD/CESSNA 400/87 directive can result in significant consequences. Under the Civil Aviation Act 1988, non-compliance with airworthiness directives is an offence, which may lead to civil or criminal penalties. Civil penalties can include fines, and in severe cases, criminal penalties may apply, which can result in imprisonment. The specific penalties depend on the circumstances of the breach and the severity of the non-compliance, but the potential consequences underscore the importance of adhering to the requirements set out in the directive.
