AD/CESSNA 150/25 - Engine to Mount Attachment

Overview

The Civil Aviation Regulations 1998, as part of the broader framework of aviation safety regulations in Australia, address critical issues concerning the maintenance and operation of aircraft, ensuring they meet specific safety standards to protect passengers and crew. Enacted by the Australian Parliament, this legislation establishes a comprehensive set of rules governing civil aviation, including specific airworthiness directives that aim to mitigate risks associated with aircraft operations. One such directive, AD/CESSNA 150/25, pertains to the Cessna 150, F150, 152, and F152 series aeroplanes, focusing on the attachment of the engine to the mount. This directive was introduced to address identified safety concerns, ensuring that certain Reims models comply with specified structural modifications within a defined timeframe to enhance overall aircraft safety. The policy objective behind these regulations is to maintain a high standard of airworthiness across all civil aviation activities in Australia. By setting mandatory compliance timelines and specific actions, such as those outlined in Cessna SL SE76-2, the Civil Aviation Regulations 1998 aim to prevent potential hazards and ensure the continued safety and reliability of aircraft operations. This legislative instrument is crucial in enforcing adherence to safety directives, thereby protecting the integrity of Australia's civil aviation sector.

Scope and Application

The Civil Aviation Regulations 1998, as amended, apply to the aviation industry across Australia, regulating various aspects of civil aviation safety, including the airworthiness of aircraft. Specifically, Part 39 - 105 of the Civil Aviation Regulations 1998 pertains to airworthiness directives issued by the Civil Aviation Safety Authority (CASA). This particular legislative instrument, AD/CESSNA 150/25, focuses on the Cessna 150, F150, 152, and F152 series aeroplanes, addressing the attachment of the engine to its mount. The directive applies to all Reims models 150 with specified serial numbers, namely FRA1500121 to 0269, FRA1500273 to 0276, FRA1500278, and FRA1500279. The requirement mandates compliance with Cessna Service Letter SE76-2, with the action to be completed within 200 hours of time in service after 31 May 1976. This regulation ensures that the specified aircraft meet necessary safety standards, thereby maintaining the integrity and safety of air travel within the Australian jurisdiction.

Key Provisions

The Civil Aviation Regulations 1998 (C1998L04923), under Part 39 - 105, specifically address the safety directives for certain Cessna aeroplanes, notably the Cessna 150, F150, 152, and F152 series. These provisions are contained in the Airworthiness Directives (AD) issued by the Civil Aviation Safety Authority (CASA). One such directive, AD/CESSNA 150/25, pertains to the engine to mount attachment of Reims models 150 with specific serial numbers (Section 5/76). The directive applies to all Reims models 150 with serial numbers ranging from FRA1500121 to 0269, FRA1500273 to 0276, FRA1500278, and FRA1500279. Under this directive, the primary requirement is that the engine to mount attachment must be addressed in accordance with Cessna Service Letter SL SE76-2. This action is mandatory and must be completed within 200 hours of the aeroplane's time in service after 31 May 1976. This timeframe is crucial for ensuring the continued airworthiness and safety of the specified aircraft models. The compliance must be strictly observed by the aircraft owners or operators, as it directly impacts the safety standards set forth by CASA. The obligations imposed by this Act are clear and precise. Aircraft owners or operators must ensure that the specified Cessna 150 models undergo the required modifications to the engine to mount attachment as outlined in Cessna Service Letter SL SE76-2. Failure to comply with this directive within the stipulated timeframe can lead to significant consequences. Non-compliance with the Airworthiness Directives can result in the aircraft being deemed unairworthy, which can prevent it from taking off or continuing a flight. Additionally, there are potential legal ramifications for breaches of these directives. CASA has the authority to impose penalties for non-compliance. These penalties can include fines and other enforcement actions as deemed appropriate by CASA. In severe cases, CASA may also suspend or revoke the aircraft’s certificate of airworthiness, which can prevent the aircraft from being operated until the required compliance is achieved. The maximum penalties for such breaches are determined by CASA and can vary depending on the severity and nature of the non-compliance.
