AD/HU 269/54 - Collective Pitch Throttle Gear - Inspection and Replacement

Overview

The Civil Aviation Regulations 1998, enacted by the Australian Government, provide a comprehensive framework for the regulation of civil aviation activities within Australia. Part 39, in particular, focuses on airworthiness directives, which are legally enforceable rules that address safety issues identified with aircraft. The Schweizer (Hughes) 269 Series Helicopters Airworthiness Directive AD/HU 269/54 aims to ensure the continued airworthiness of models 269A and 269B by mandating the inspection and replacement of collective pitch throttle gear. This directive was introduced to address safety concerns identified through the Hughes SIN N-131 and FAA AD 75-15-02 documents. Compliance with this directive is required within 100 hours of time in service after 31 July 1976, ensuring that identified safety issues are promptly addressed, thereby enhancing the overall safety standards of civil aviation within Australia. The policy objective is to maintain and improve aviation safety by ensuring that aircraft remain in a safe and airworthy condition through the implementation of necessary maintenance actions.

Scope and Application

The Civil Aviation Safety Authority (CASA) has issued an Airworthiness Directive (AD) under the Civil Aviation Regulations 1998, specifically in Part 39, which mandates the inspection and replacement of the collective pitch throttle gear in Schweizer (Hughes) 269 series helicopters, including the models 269A and 269B. This directive applies to the operators and owners of these particular helicopter models and seeks to ensure that they comply with specific safety standards. The directive is enforceable within the jurisdiction of the Commonwealth of Australia, meaning it applies nationally and is overseen by CASA. Compliance with this AD is mandatory for those operating within the Australian aviation sector and must be carried out within 100 hours of time in service after 31 July 1976. This timeframe is referenced in the directive based on the Hughes Service Information Notice N-131 and the Federal Aviation Administration's AD 75-15-02, which this Australian directive aligns with. There are no exclusions or exemptions mentioned within the text, indicating that all operators of the specified helicopter models must adhere to the directive's requirements.

Key Provisions

The main operative sections of this legislative instrument, specifically AD/HU 269/54, pertain to the inspection and replacement of the collective pitch throttle gear on Schweizer (Hughes) 269 Series Helicopters, including models 269A and 269B. These sections mandate that the relevant parts be inspected and, if necessary, replaced in compliance with Hughes SIN N-131 and FAA AD 75-15-02. This requirement applies to helicopters that have accumulated 100 hours of time in service after 31 July 1976. The Civil Aviation Regulations 1998 impose specific obligations on the parties and entities governed by this legislation. Operators of Schweizer (Hughes) 269 Series Helicopters must ensure that the collective pitch throttle gear is inspected and maintained in accordance with the specified directives. This includes adhering to the detailed procedures outlined in Hughes SIN N-131 and FAA AD 75-15-02, ensuring that any necessary replacements are carried out by qualified personnel. The aim is to maintain the airworthiness of the aircraft and ensure the safety of all persons on board. Failure to comply with the requirements of AD/HU 269/54 can lead to serious consequences. According to the Civil Aviation Regulations 1998, non-compliance with airworthiness directives can result in civil penalties. For corporate entities, the maximum penalty is a fine of up to $1,050,000, while natural persons can face a maximum penalty of up to $210,000. Additionally, the operation of a non-compliant aircraft may lead to its grounding, further enforcement actions, and potential criminal charges if the non-compliance results in an accident or endangers safety. Therefore, adherence to these directives is not only a regulatory requirement but also a critical component of aviation safety.
