AD/AA-5/10 Amdt 1 - Carburettor Mixture Control - Modification

Overview

The Civil Aviation Regulations 1998, amended in 2006, were enacted to establish and maintain a robust regulatory framework governing civil aviation in Australia. This legislative instrument, part of the broader regulatory system overseen by the Civil Aviation Safety Authority (CASA), aims to ensure that all aspects of civil aviation operations, including aircraft airworthiness, safety standards, and compliance with international conventions, are met to protect public safety and national security. One specific amendment, F2006B02042, pertains to the Gulfstream (Grumman American/ American Aviation) AA-5 Series Aeroplanes and addresses issues related to the modification of the carburettor mixture control as detailed in Grumman American Aviation Service Bulletin No. 150A. The policy objective of this directive is to mandate compliance within 100 hours’ time in service after 20 February 1976 for specific model AA5B aircraft with serial numbers AA5B-0001 to AA5B-0215, thereby enhancing operational safety and reliability.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, pertains to the Airworthiness Directives issued by the Civil Aviation Safety Authority (CASA) and applies to all aircraft within the Commonwealth of Australia. This particular legislation focuses on Gulfstream (Grumman American/American Aviation) AA-5 Series aeroplanes, with the amendment AD/AA-5/10Amdt 1 addressing modifications to the Carburettor Mixture Control for model AA5B with serial numbers ranging from AA5B-0001 to AA5B-0215. Compliance with this directive is mandatory and must be achieved within 100 hours of time in service following 10 February 1976, as outlined in Grumman American Aviation Service Bulletin No. 150A. The regulation is directly applicable to the specified aircraft models and serial numbers, ensuring adherence to safety standards set by CASA. The directive underscores the importance of timely modifications to maintain airworthiness and safety in accordance with Australian aviation laws.

Key Provisions

The primary sections of the AD/AA-5/10 Amendment 1 address the modification of the carburettor mixture control for the Gulfstream (Grumman American/ American Aviation) AA-5 Series Aeroplanes, specifically for the Model AA5B with serial numbers AA5B-0001 to AA5B-0215 (Section 1). This directive mandates that the specified modification must be completed within 100 hours of time in service after 10 February 1976 (Section 2). Compliance with this directive is documented through the Grumman American Aviation Service Bulletin No. 150A (Section 3). This legislative instrument imposes several obligations on the relevant parties, including aircraft operators and maintenance organisations. Operators of the affected Gulfstream AA-5B aircraft must ensure that the required modification to the carburettor mixture control is carried out in accordance with the specifications outlined in Grumman American Aviation Service Bulletin No. 150A. Maintenance organisations are required to perform the modification within the stipulated timeframe, adhering to the regulatory standards to ensure the airworthiness of the aircraft. The Civil Aviation Safety Authority (CASA) will monitor compliance with this directive, ensuring that all necessary actions are taken to maintain safety standards (Section 4). Failure to comply with the provisions of AD/AA-5/10 Amendment 1 may result in significant consequences. Under the Civil Aviation Act 1988, non-compliance with airworthiness directives can lead to civil penalties. For natural persons, the maximum penalty is up to $200,000, while for bodies corporate, the penalty can be up to $1,000,000 (Section 5). Additionally, continued operation of the aircraft without the required modification may result in CASA taking enforcement actions, including grounding the aircraft, imposing fines, or pursuing legal proceedings against the operator or maintenance organisation responsible for the non-compliance (Section 6). It is imperative that all parties adhere strictly to the directives to avoid these serious repercussions.
