AD/GOV/4 - Flyweight Pin Retainer - Modification

Overview

The Civil Aviation Regulations 1998, as amended and incorporated in the Australian legislative framework, play a crucial role in maintaining the safety standards within the civil aviation sector. One particular legislative instrument, F2006B10311, specifically addresses the issue of propeller governors by introducing Airworthiness Directives. This legislative instrument was enacted to ensure that aircraft propeller governors, particularly the Woodward governors P/N 8210-020, adhere to specified safety standards to prevent mechanical failure and enhance flight safety. The directive was issued by the Civil Aviation Safety Authority and is aimed at ensuring compliance with the requirements set forth in Allison Commercial Engine Bulletin 250-B17/B17B TP CEB-1051, with all modifications to be implemented before the installation of the governor in an aircraft after 30 June 1976. This policy objective underscores the commitment to maintaining rigorous safety standards within the aviation industry.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 – 107 concerning the Civil Aviation Safety Authority's Schedule of Airworthiness Directives, mandates compliance with the directive AD/GOV/4 concerning the flyweight pin retainer modification for all Woodward governors with part number 8210-020. This applies universally to these particular types of governors installed in aircraft. The directive necessitates compliance with the requirements outlined in Allison Commercial Engine Bulletin 250-B17/B17B TP CEB-1051 and must be adhered to before these governors are installed in any aircraft after 30 June 1976. The regulations are enforced by the Civil Aviation Safety Authority, which has the jurisdiction to oversee compliance with airworthiness standards within the Commonwealth of Australia. This legislation applies to aircraft operators and maintenance personnel who must ensure that the specified modifications are implemented in accordance with the outlined directives to maintain the safety and airworthiness of the aircraft.

Key Provisions

The Civil Aviation Regulations 1998, particularly within Part 39 - 107, include specific Airworthiness Directives (ADs) designed to ensure the safety of aviation operations. One such directive, AD/GOV/4, pertains to the modification of the flyweight pin retainer for Woodward governors P/N 8210-020 (section 1). This directive is intended to be complied with before any installation in an aircraft following 30 June 1976 (section 2). The directive references Allison Commercial Engine Bulletin 250-B17/B17B TP CEB-1051 as the document detailing the required modifications (section 3). The obligations under this AD are clear and specific. Operators of aircraft equipped with the specified Woodward governors must ensure that the flyweight pin retainer is modified in accordance with the requirements outlined in Allison Commercial Engine Bulletin 250-B17/B17B TP CEB-1051. This modification is mandatory for compliance with airworthiness standards, and any non-compliance could lead to operational issues or safety hazards. The directive aims to address known issues related to the flyweight pin retainer to prevent potential failures that could compromise aircraft safety (section 4). Breaching the requirements set forth in AD/GOV/4 can have serious consequences. Under the Civil Aviation Regulations 1998, non-compliance with ADs is considered an offence. Operators who fail to adhere to these directives may face civil penalties, including fines and potential grounding of the affected aircraft. In severe cases, where non-compliance results in an unsafe condition that leads to an accident, criminal charges could be pursued. The maximum penalties for such offences can include substantial fines and imprisonment, reflecting the gravity of ensuring aviation safety (section 5).
