AD/CESSNA 180/34 - Nosewheel Closure Collar

Overview

The Civil Aviation Regulations 1998, which were enacted by the Parliament of Australia, form a crucial part of the regulatory framework governing aviation safety within the country. Among its various provisions, Part 39, specifically AD/CESSNA 180/34, addresses the issue of ensuring the airworthiness of certain Cessna aeroplanes, including models 180, 182, and Wren 460 series. This legislative instrument was introduced to rectify gaps in the existing regulations concerning the safety of these specific aircraft models, aiming to enhance overall aviation safety by mandating certain maintenance actions. The policy objective behind this regulation is to ensure that all specified aircraft meet necessary safety standards, thereby protecting the well-being of passengers and crew, as well as maintaining the integrity of the national aviation system.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, mandates compliance with airworthiness directives issued by the Civil Aviation Safety Authority (CASA) for the specified Cessna 180, 182, and Wren 460 Series Aeroplanes. This legislation applies to all model 182 aeroplanes with serial numbers ranging from 18261427 to 18261559. The directive requires that specific maintenance actions, detailed in Cessna Service Letter SE73-2 Item 1, be undertaken to ensure the nosewheel closure collar meets the necessary safety standards. Compliance with this directive must be achieved within 100 hours of time in service following the issuance date of 28 February 1973. The regulations are enforced within the Commonwealth of Australia, and while they apply to a specific subset of aircraft models, any broader applications or exclusions are detailed in the subordinate instruments or CASA directives.

Key Provisions

The main operative sections of this legislative instrument pertain to the airworthiness directives for specific Cessna aeroplane models, namely the 180, 182, and Wren 460 series. Section 105 of the Civil Aviation Regulations 1998 outlines the applicability and requirements of these directives. For instance, AD/CESSNA 180/34 pertains to the nosewheel closure collar of model 182 with serial numbers ranging from 18261427 to 18261559. The requirement here is to comply with Cessna SL SE73-2 Item 1, which must be implemented within 100 hours of time in service after 28 February 1973. These sections impose clear obligations on the operators and owners of the affected aircraft. They must ensure that the specified maintenance actions are carried out as per the directive to maintain the airworthiness of the aircraft. This includes verifying that the nosewheel closure collar is correctly installed and functional, as per the detailed specifications provided by Cessna in their Service Letter SE73-2 Item 1. Compliance with these directives is mandatory, and failure to adhere to the prescribed timeframe can result in the aircraft being deemed unairworthy. The Civil Aviation Regulations 1998 also detail the consequences of non-compliance with these airworthiness directives. Breaching the specified requirements can lead to significant penalties. While the exact penalties are not detailed in the provided text, typically, non-compliance with airworthiness directives can result in fines, potential grounding of the aircraft, and other enforcement actions by the Civil Aviation Safety Authority (CASA). The severity of the penalties can vary depending on the nature and extent of the breach, but they are designed to ensure that all aircraft maintain the highest standards of safety and airworthiness.
