AD/CESSNA 170/3 - Nose Wheel Strut

Overview

The Civil Aviation Regulations 1998, enacted by the Parliament of the Commonwealth of Australia, constitute a comprehensive regulatory framework designed to ensure the safety and efficiency of civil aviation operations within the country. One specific legislative instrument, F2006B04961, addresses the safety of certain aircraft models by issuing Airworthiness Directives. This particular directive pertains to the Cessna 170, 172, F172, FR172, and 175 series aeroplanes, aiming to address identified safety issues by mandating specific actions, such as compliance with manufacturer service letters. The overarching policy objective of these regulations is to enhance aviation safety by ensuring that aircraft meet stringent airworthiness standards. The enactment of this directive under the Civil Aviation Regulations 1998 is a response to identified safety gaps and risks associated with the specified models of Cessna aeroplanes. By issuing this Airworthiness Directive, the Civil Aviation Safety Authority seeks to mitigate potential hazards through the enforcement of compliance deadlines and the specification of corrective actions, thereby safeguarding the integrity and reliability of civil aviation activities.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, mandates the Civil Aviation Safety Authority's Schedule of Airworthiness Directives, which includes detailed safety measures and operational requirements for various aircraft models. For the Cessna 170, 172, F172, FR172, and 175 series aeroplanes, Airworthiness Directive AD/CESSNA 170/3 outlines stringent measures concerning the nose wheel strut. This directive applies to Model 172 aeroplanes prior to serial number 28332 and mandates compliance with Cessna Service Letter No 170-5, with the requirement that any necessary actions be completed before 1 September 1971. These regulations are applicable across the Commonwealth of Australia and are enforced by the Civil Aviation Safety Authority, ensuring that the specified aircraft meet safety standards that are critical for operational safety and airworthiness. This legislation does not explicitly state any exclusions, exemptions, or thresholds, and the application can be further refined through subordinate instruments that may provide additional detail or clarification on compliance requirements.

Key Provisions

The primary operative sections of the Civil Aviation Regulations 1998, as amended, under PART 39 - 105, pertain to the Civil Aviation Safety Authority's (CASA) Schedule of Airworthiness Directives. Specifically, AD/CESSNA 170/3 targets the nose wheel strut of certain Cessna aircraft models. This directive applies to the Cessna Model 172 prior to serial number 28332 (section 1). The requirement is for the aircraft to be serviced according to Cessna Service Letter No 170-5, with compliance expected before 1 September 1971 (section 2). Under these regulations, the parties or entities governed, primarily the owners and operators of the affected Cessna aircraft, must ensure that the specified maintenance action is carried out on the nose wheel strut. This involves following the detailed instructions laid out in Cessna Service Letter No 170-5. The regulation mandates that this maintenance must be completed before the specified deadline of 1 September 1971 to maintain the airworthiness of the aircraft. Failure to comply with the requirements set out in AD/CESSNA 170/3 can result in severe consequences. Civil Aviation Regulations 1998 impose significant penalties for non-compliance. The breach of these airworthiness directives can lead to the grounding of the aircraft, which in turn may result in administrative fines, legal action, and potential criminal charges against the aircraft owners or operators. The exact penalties are not specified in the text but are generally substantial under civil aviation law, reflecting the importance of adhering to airworthiness standards for safety reasons.
