AD/CESSNA 150/10 Amdt 2 - Plastic Control Wheel

Overview

The Civil Aviation Regulations 1998 (Cth), under Part 39 - 105, introduces the Civil Aviation Safety Authority's Schedule of Airworthiness Directives, addressing safety concerns related to the operation of specific aircraft. This legislative instrument aims to ensure that aircraft remain in airworthy condition by mandating compliance with specific service bulletins and safety directives, particularly for the Cessna 150, F150, 152, and F152 series aeroplanes. The Civil Aviation Safety Authority, as the enforcing body, has identified the need for regular checks and maintenance on plastic control wheels of these aircraft models to prevent potential operational failures. The overarching policy objective is to enhance aviation safety by ensuring that aircraft meet necessary safety standards and are maintained in accordance with manufacturer recommendations.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, governs the airworthiness of various aircraft types within Australia. The Cessna 150, F150, 152 & F152 Series Aeroplanes fall under this regulation, particularly concerning the AD/CESSNA 150/10 Amendment 2 for plastic control wheels. This directive applies to all models of the aforementioned aircraft series that are fitted with plastic control wheels, mandating compliance with specific Service Letters issued by Cessna. The regulation requires compliance at specified intervals, with Cessna Service Letter No. 62-44 necessitating action within 100 hours of time in service, and Cessna Service Letter No. 64-8 requiring compliance within 500 hours of time in service. These regulations are applicable across Australia, as they are part of the overarching framework established by the Commonwealth of Australia. The scope of these directives ensures that the maintenance and inspection of plastic control wheels are conducted consistently to maintain the airworthiness of the specified aircraft models.

Key Provisions

The Civil Aviation Regulations 1998, specifically Part 39 - 105 under the Civil Aviation Safety Authority Schedule of Airworthiness Directives, mandate critical safety measures for certain Cessna aeroplanes. For the Cessna 150, F150, 152, and F152 series, Amendment 2 to Airworthiness Directive AD/CESSNA 150/10 pertains to the plastic control wheel (section 5/69). This directive applies to all models equipped with plastic control wheels (section 5/69). The primary requirement is for the action to be taken in accordance with Cessna Service Letters (SL) No. 62-44 and No. 64-8 (section 5/69). Compliance with these service letters must occur at specific intervals: for document 1(a), compliance is required at intervals not exceeding 100 hours of time in service, and for document 1(b), compliance must be achieved at intervals not exceeding 500 hours of time in service. The obligations imposed by these regulations are stringent, ensuring that the plastic control wheels on these aircraft are maintained and inspected according to the specified service letters. This involves regular checks and actions as detailed in the service letters to ensure the integrity and safety of the control wheel, which is a critical component for aircraft operation. The directive ensures that operators and owners of these aircraft adhere to the manufacturer's guidelines to prevent any potential failure that could compromise flight safety. Failure to comply with the directives and service letters can lead to severe consequences. While the specific offences and penalties are not detailed in the provided text, it is understood that non-compliance with Civil Aviation Regulations can result in both civil and criminal penalties. Typically, civil penalties can include fines, and in severe cases, criminal penalties could involve imprisonment. The exact penalties would be determined based on the specific regulations and the nature of the breach, but the overarching intent is to enforce strict adherence to ensure the safety and reliability of aircraft operations.
