Overview
The Civil Aviation Regulations 1998, enacted by the Parliament of Australia, represent a comprehensive framework designed to regulate civil aviation operations within the country, ensuring the safety and efficiency of air travel. One specific legislative instrument, F2006B09568, addresses the critical issue of ensuring the airworthiness of aircraft, specifically targeting the Enstrom F-28 Series Helicopters. This instrument was introduced to mitigate risks associated with the main rotor hub retention lock washer, requiring its replacement to enhance safety. The policy objective is clearly stated as ensuring that all affected models comply with the directive within a specified timeframe, thereby maintaining the highest safety standards for air operations. This legislative measure underscores the Civil Aviation Safety Authority's commitment to enforcing stringent safety protocols to protect both the aviation industry and the public.
Scope and Application
The Civil Aviation Regulations 1998, specifically Part 39 - 105, mandates the application of Airworthiness Directives for particular aircraft models, as exemplified by the Enstrom F-28 Series Helicopters. This directive, AD/ENST 28/13, concerns the replacement of the main rotor hub retention lock washer and applies to all models F-28A with serial numbers ranging from 4 to 275, 277, 278, 280 to 283, and models 280 with serial numbers from 1001 to 1006. This legislation targets the specified helicopter models, necessitating compliance from operators of these aircraft. The directive is to be adhered to within 25 hours of the aircraft's time in service following 30 April 1976. This regulation ensures that the aircraft meet the necessary safety standards outlined in the referenced Enstrom Service Note No. 0025A or the FAA AD 75-22-10. The scope of the regulation is limited to the specified models and serial numbers, ensuring that only the affected helicopters are required to comply with the directive.
Key Provisions
The Civil Aviation Regulations 1998, specifically within Part 39 - 105 and the Civil Aviation Safety Authority Schedule of Airworthiness Directives, address the maintenance and airworthiness of the Enstrom F-28 Series Helicopters, particularly focusing on the Main Rotor Hub Retention Lock Washer replacement (AD/ENST 28/13 4/76). This directive applies to all models F-28A with serial numbers ranging from 4 to 275, 277, 278, 280 to 283, and models 280 with serial numbers 1001 to 1006 (section 39-105). Compliance with this directive must be achieved within 25 hours of time in service after 30 April 1976.
To comply with this directive, the operators of the specified Enstrom F-28 Series Helicopters must ensure the Main Rotor Hub Retention Lock Washer is replaced as outlined in either Enstrom Service Note No. 0025A or FAA AD 75-22-10 (section 39-105). This requirement mandates that the specified models undergo the necessary maintenance to rectify potential safety issues associated with the Main Rotor Hub Retention Lock Washer, ensuring the continued airworthiness and safety of the aircraft.
The obligations imposed by this directive are clear and specific. Operators must adhere to the outlined compliance timeframe, ensuring the replacement of the Main Rotor Hub Retention Lock Washer is completed within the stipulated 25 hours of time in service following 30 April 1976. Failure to comply with this directive may result in significant legal and safety repercussions, as it is crucial to maintain the integrity and safety of the aircraft's operation.
Failure to comply with the requirements of AD/ENST 28/13 4/76 may result in various consequences. While the specific penalties are not detailed in the excerpt, non-compliance with airworthiness directives typically attracts severe penalties under civil aviation law. These may include fines, the grounding of non-compliant aircraft, and potential criminal charges if the non-compliance leads to safety incidents or accidents. The severity of the penalties underscores the importance of adhering to these directives to ensure the safety and regulatory compliance of the aircraft.
