AD/CESSNA 210/50 Amdt 1 - Engine and Turbocharger Installation - Checks and Modification

Overview

The Civil Aviation Regulations 1998, under Part 39 - 105 of the Civil Aviation Safety Authority (CASA) Schedule of Airworthiness Directives, include specific directives for aircraft safety, particularly focusing on the Cessna 210 Series Aeroplanes. This legislative instrument was enacted to address safety concerns related to engine overheating and detonation, which could occur due to excessively lean mixtures during high power operations. The policy objective is to mitigate these risks through mandatory checks and modifications, ensuring the airworthiness of affected aircraft. The directive AD/CESSNA 210/50 Amendment 1 pertains to the Cessna 210N series with specific serial numbers and requires compliance within 200 hours of time in service after 31 October 1981. It was originally introduced to enhance safety by preventing engine issues and was later amended to cover a broader range of serial numbers. The modifications aim to reduce the likelihood of detonation and improve climb performance. The directive is enforced by CASA to maintain stringent safety standards within the aviation industry.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, outlines the Civil Aviation Safety Authority's (CASA) schedule of airworthiness directives for various aircraft types, including the Cessna 210 series aeroplanes. This particular directive, AD/CESSNA 210/50 Amendment 1, applies to the model P210N series with serial numbers ranging from P21000001 to P21000690 that do not incorporate Cessna Service Kit No. SK210-98B. This legislation mandates compliance within 200 hours of time in service after 31 October 1981, targeting issues such as engine overheating, detonation, and the improvement of climb performance. The directive references CESSNA SIL No. SE 81-35 and Supplement No. 1 or FAA AD 81-15-05, Amendment No. 39-4168, for the necessary checks and modifications. The directive's scope is limited to the specified serial numbers of the P210N series and does not apply to other Cessna models or serial numbers outside this range. The directive extends its application through the cited references and amendments, ensuring continuous improvement and compliance with safety standards.

Key Provisions

The main operative sections of the Civil Aviation Regulations 1998, Part 39 - 105, specifically AD/CESSNA 210/50 Amendment 1, mandate that all Model P210N series Cessna 210 aeroplanes with serial numbers P21000001 to P21000690 that have not incorporated Cessna Service Kit No. SK210-98B must undergo certain checks and modifications (section 10/81). The directive outlines the necessary actions to address engine overheating and detonation issues, which primarily stem from excessively lean mixtures during high power operation. It also includes modifications to improve climb performance. The obligations imposed by this Airworthiness Directive include the requirement for compliance within 200 hours of time in service following 31 October 1981 (section 10/81). Specifically, the directive mandates that affected aircraft must incorporate CESSNA SIL No. SE 81-35 and its supplements or FAA AD 81-15-05, Amendment No. 39-4168. This ensures that the aircraft meet the safety standards set forth to prevent engine overheating and detonation, as well as to enhance overall performance. Failure to comply with the directives stipulated in AD/CESSNA 210/50 Amendment 1 can result in significant consequences. The Civil Aviation Safety Authority can impose penalties on any party or entity that fails to adhere to the requirements. While the specific penalties are not detailed in the directive itself, non-compliance generally results in regulatory enforcement actions, which may include fines or other administrative measures. It is crucial for operators and owners of the affected aircraft to ensure timely and accurate compliance to avoid any legal repercussions.
