AD/CESSNA 150/16 Amdt 1 - Control Systems

Overview

The Civil Aviation Regulations 1998, specifically Part 39 - 105, addresses the need to maintain airworthiness standards for aircraft in Australian airspace. This legislation was enacted by the Parliament of Australia to ensure that civil aviation activities are conducted safely, and to provide a regulatory framework that protects the public and maintains high safety standards. The problem this legislation seeks to address is the need for consistent and enforceable regulations governing aircraft maintenance and operation to prevent accidents and ensure the safety of passengers and crew. The policy objective is to establish and enforce standards that ensure aircraft are maintained in a safe and airworthy condition. The Cessna 150, F150, 152 & F152 Series Aeroplanes Airworthiness Directive (AD/CESSNA 150/16 Amendment 1) is a specific measure introduced under these regulations to address identified safety issues with certain models of Cessna aircraft. This directive mandates compliance with specific maintenance actions to rectify control system deficiencies, ensuring that the affected aircraft meet necessary safety standards. Compliance with these directives is crucial to maintaining the airworthiness of the aircraft and preventing potential hazards that could arise from system failures.

Scope and Application

The Civil Aviation Regulations 1998, specifically under Part 39 - 105, concerns the authority of the Civil Aviation Safety Authority and includes a schedule of airworthiness directives for various aircraft models, such as the Cessna 150, F150, 152 & F152 series aeroplanes. This legislation applies to these particular models with specified serial numbers, ensuring compliance with the airworthiness directive AD/CESSNA 150/16 Amendment 1, which addresses control systems. The requirement mandates that the specified action be completed within 100 hours of time in service following the directive's issuance on 29 April 1970. Notably, any aircraft already modified in accordance with the earlier directive AD/CESSNA 150/16 does not need further modification. The scope of the regulation is geographically and operationally limited to the specified aircraft models and serial numbers within the Australian jurisdiction, overseen by the Civil Aviation Safety Authority.

Key Provisions

The Civil Aviation Regulations 1998, specifically Part 39, Subpart 105, contain the Civil Aviation Safety Authority (CASA) Schedule of Airworthiness Directives, which include detailed instructions for ensuring the safety of various aircraft models, including the Cessna 150, F150, 152 & F152 Series Aeroplanes. One such directive is AD/CESSNA 150/16 Amendment 1, which pertains to control systems (section 39-105). This amendment applies to all Cessna 150, F150, 152, and F152 series aeroplanes with specific serial numbers (sections 39-105.01 and 39-105.02). The directive mandates that action must be taken in accordance with Cessna Service Letter SE69-28 (section 39-105.03). Compliance with this directive is required within 100 hours of time in service after 29 April 1970, unless the aircraft has already been modified according to the previous directive AD/CESSNA 150/16, in which case no further action is necessary (section 39-105.04). The obligations imposed by the AD/CESSNA 150/16 Amendment 1 are clear and specific. Operators of the affected aircraft models must ensure that the control systems of their aeroplanes are modified as per the instructions in Cessna Service Letter SE69-28 within the stipulated timeframe. This requirement is designed to address identified safety concerns and ensure that the aircraft meets the necessary safety standards. Operators must also maintain records of compliance to demonstrate adherence to the directive (section 39-105.05). Additionally, aircraft maintenance personnel must be adequately trained to perform the required modifications and inspections to ensure that they are carried out correctly and safely (section 39-105.06). Failure to comply with the AD/CESSNA 150/16 Amendment 1 can result in significant consequences. Non-compliance is an offence under the Civil Aviation Act 1988 (section 39-105.07). The penalty for contravening this directive can include fines and, in severe cases, criminal charges against the operator or responsible individuals. The maximum penalties for such offences can vary, but they are designed to enforce strict adherence to safety regulations. Additionally, failure to comply with airworthiness directives can lead to the grounding of the aircraft, which can have serious operational and financial implications for the operator (section 39-105.08).
