AD/S-76/2 - Engine Oil Filler Service Door - Modification

Overview

The Civil Aviation Regulations 1998 (Cth) were enacted to provide a comprehensive regulatory framework for civil aviation in Australia, ensuring safety and operational standards are met across the industry. Within this legislative instrument, Part 39 - 105 specifically addresses Airworthiness Directives, including AD/S-76/2 concerning the Sikorsky S-76 Series Helicopters. This directive was introduced to address a safety concern related to the engine oil filler service door of certain S-76 models, specifically those with serial numbers within the ranges indicated. The Civil Aviation Safety Authority, under the authority of the Commonwealth Parliament, issues these directives to mandate compliance, ensuring that modifications are implemented to mitigate potential safety risks. The policy objective behind AD/S-76/2 is to enhance the reliability and safety of the aircraft by requiring a backup method for securing the engine oil filler service door, as recommended by the manufacturer in Sikorsky CSB No. 76-53-3. Compliance with this directive must be achieved within 100 hours of the helicopter being in service after 30 September 1979.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, mandates the implementation of airworthiness directives through the Civil Aviation Safety Authority (CASA) to ensure the safe operation of aircraft within Australian airspace. The legislative instrument F2006B06702, concerning AD/S-76/2 for Sikorsky S-76 series helicopters, applies to all models within the specified serial numbers. These regulations apply to the aircraft owners, operators, and maintenance personnel, ensuring that they adhere to the outlined requirements for the engine oil filler service door modification. The directive requires compliance within 100 hours of time in service after 30 September 1979, as specified in Sikorsky CSB No. 76-53-3, and is subject to the jurisdiction of the Commonwealth of Australia. While the primary focus is on enhancing safety, there are no stated exclusions or exemptions within this directive, making it a mandatory requirement for the specified Sikorsky S-76 helicopters operating in Australian airspace. The scope of this directive is further extended or refined through subordinate instruments as necessary, ensuring that the regulations remain current and effective.

Key Provisions

The Civil Aviation Regulations 1998, Part 39 - 105, specifically addresses the requirements for the airworthiness of aircraft, including the Sikorsky S-76 Series Helicopters. In this context, AD/S-76/2 pertains to the engine oil filler service door modification for certain serial numbers of the Sikorsky S-76 series helicopters (section 1). This directive, Sikorsky CSB No. 76-53-3, mandates that the engine oil filler service door must be modified to provide a backup method of securing it, as advised by the manufacturer. Compliance with this directive is required within 100 hours of time in service after 30 September 1979 (section 2). Operators and owners of the specified Sikorsky S-76 helicopters must ensure that the engine oil filler service door modification is carried out as per the requirements set out in the directive. This involves implementing a backup method of securing the door to prevent any potential hazards associated with the door being left unsecured (section 3). The responsibility for compliance falls on the operator or owner, who must ensure that the modification is performed by qualified personnel and that the aircraft is kept in a state of airworthiness at all times (section 4). Failure to comply with the provisions of AD/S-76/2 can result in significant consequences. Under the Civil Aviation Act 1988, non-compliance with airworthiness directives is an offence. The penalties for such offences can include fines and imprisonment. Specifically, for corporations, the maximum penalty can be substantial, often up to several thousand Australian dollars, depending on the severity and frequency of the offence (section 5). Additionally, continued operation of a non-compliant aircraft can result in the aircraft being grounded, which can have serious operational and financial repercussions for the operator (section 6).
