AD/CESSNA 180/38 - Nose Wheel Pivot Bolt

Overview

The Civil Aviation Regulations 1998, enacted by the Australian Parliament, form a comprehensive framework governing all aspects of civil aviation within Australia. One of the specific legislative instruments under this regulation is the Airworthiness Directive issued by the Civil Aviation Safety Authority (CASA). This directive addresses specific issues relating to the maintenance and safety of particular aircraft models, including the Cessna 180, 182, and Wren 460 series aeroplanes. The policy objective of these directives is to ensure that the aircraft remain airworthy and safe for operation by mandating regular inspections and maintenance actions on identified components. The directive for the Cessna models focuses on the nose wheel pivot bolt, requiring its retirement from service under specified conditions to mitigate the risk of structural failure. This regulatory approach aims to enhance overall aviation safety by proactively addressing potential safety hazards through targeted maintenance requirements.

Scope and Application

The Civil Aviation Regulations 1998, specifically under Part 39 - 105, applies to Cessna 180, 182, and Wren 460 series aeroplanes, focusing on the airworthiness directives for nose wheel pivot bolts. This legislation targets all amphibian models equipped with Scott nose wheel assemblies, ensuring compliance with stringent safety standards. The regulations mandate the retirement of nosewheel pivot bolts from service following specific timeframes, either within 100 hours after a particular date for bolts that have already accrued 500 hours of service, or before they reach 600 hours for others, with subsequent intervals not exceeding 600 hours. This regulation is binding across the Commonwealth of Australia and applies uniformly, ensuring that aircraft maintain high safety standards. The scope of the legislation is precise, covering only the specified models and their particular components, while the applicability is geographically extensive, reaching all relevant aircraft within the Australian jurisdiction.

Key Provisions

The Civil Aviation Regulations 1998, specifically within Part 39, section 105, detail the Airworthiness Directives (AD) for various aircraft, including the Cessna 180, 182 and Wren 460 series aeroplanes. The directive AD/CESSNA 180/38 addresses the nose wheel pivot bolt for all amphibian models with Scott nose wheel assemblies (Section 105.05). This regulation requires the retirement of the nosewheel pivot bolts from service to ensure the aircraft's safety and airworthiness. The directive stipulates that for those nosewheel pivot bolts which have achieved 500 hours of time in service, they must be retired from service within 100 hours of time in service after 31 January 1974 (Section 105.05(1)). For all other nosewheel pivot bolts, they must be retired before they achieve 600 hours of time in service, and subsequently at intervals not exceeding 600 hours (Section 105.05(2)). Under these regulations, the obligations imposed on the operators and owners of these aircraft are quite specific. Operators must ensure that the nosewheel pivot bolts are retired from service within the specified timeframes. This involves keeping accurate records of the time in service for each bolt and scheduling inspections and replacements accordingly. Owners and operators must also ensure that only qualified personnel carry out these tasks to comply with the safety standards set forth by the Civil Aviation Safety Authority (CASA). Failure to adhere to these requirements can result in significant legal and safety repercussions. Violations of the Civil Aviation Regulations 1998, particularly those outlined in the Airworthiness Directives, can lead to serious consequences. CASA has the authority to enforce these regulations and can impose penalties for non-compliance. Offences under these regulations can result in both civil and criminal penalties. For instance, individuals or corporations found in breach of these directives may face substantial fines. The maximum penalties can vary, but they are designed to ensure strict adherence to safety standards and can include imprisonment for serious breaches. Ensuring compliance not only avoids these penalties but also upholds the highest standards of aviation safety.
