AD/CESSNA 310/11 - Landing Gear Torque Tubes - Inspection

Overview

The Civil Aviation Regulations 1998, as amended and published in 1998 by the Australian Government, are a comprehensive set of rules governing all aspects of civil aviation in Australia. Part 39, specifically addressing Airworthiness Directives, ensures that aircraft are maintained to a standard that guarantees safety during operation. The legislation was enacted to maintain high safety standards in civil aviation, thereby preventing accidents and ensuring the safety of passengers, crew, and the general public. The Civil Aviation Safety Authority (CASA) is the enforcing body, with a policy objective of ensuring that all aircraft comply with stringent safety standards. This particular legislative instrument, F2006B08139, pertains to Cessna 310 series aeroplanes and mandates inspections of the landing gear torque tubes to prevent potential structural failures that could compromise safety during flight operations.

Scope and Application

The Civil Aviation Safety Authority's Schedule of Airworthiness Directives, specifically AD/CESSNA 310/11, applies to all Cessna 310C, 310D, and 310F models, mandating the inspection of landing gear torque tubes. This regulation is part of the Civil Aviation Regulations 1998, which operate under the jurisdiction of the Commonwealth of Australia and thus apply nationally. The directive necessitates that inspections of the landing gear torque tubes be performed at intervals not exceeding 100 hours of time in service, ensuring that these aircraft maintain the requisite safety standards for operation. No exclusions or exemptions are specified in the directive, thereby encompassing all aircraft of the specified models within its scope. The regulation can be further detailed or extended through subordinate instruments issued by the Civil Aviation Safety Authority, providing additional clarity or specifications as needed.

Key Provisions

The primary operative section of this legislative instrument is Section 12/62, which specifies the applicability of the Airworthiness Directive (AD) to all models 310C, 310D, and 310F of Cessna 310 Series Aeroplanes (12/62 Applicability). This section mandates that the inspection of the landing gear torque tubes be carried out in accordance with the requirements set forth in Cessna Service Letter No. 62-76. These inspections are crucial to ensure the continued airworthiness of the specified aircraft models and must be completed at intervals not exceeding 100 hours of time in service (12/62 Compliance). The obligations imposed by this Act on the parties or entities it governs include ensuring that all inspections are performed by qualified personnel following the detailed procedures outlined in the referenced Cessna Service Letter. Operators of these aircraft must maintain accurate records of all inspections conducted and ensure that any necessary repairs or replacements are carried out promptly to maintain compliance with the safety standards set by the Civil Aviation Safety Authority (CASA). Additionally, operators must ensure that all maintenance personnel are adequately trained and certified to perform these inspections and any subsequent work required. Failure to comply with the provisions of Section 12/62 may result in serious consequences, both civil and criminal. Civilly, CASA may take enforcement actions against non-compliant operators, including the issuance of directives, fines, and potential grounding of the aircraft until compliance is achieved. Criminally, operators found in breach of these safety directives may face penalties, including substantial fines and imprisonment. The exact penalties depend on the severity of the non-compliance and any resultant safety risks, but they can be severe, reflecting the critical nature of maintaining aircraft airworthiness. The Civil Aviation Regulations 1998 provide for maximum penalties for breaches, which can include significant fines and imprisonment terms for those found guilty of non-compliance.
