AD/CESSNA 207/39 - Alternate Static Air Source Valve

Overview

The Civil Aviation Act 1988 was enacted to provide a comprehensive legislative framework for the regulation of civil aviation in Australia. It serves to ensure the safety of air navigation and the continuing airworthiness of aircraft registered in Australia. In this context, the Civil Aviation Safety Regulations 1998 were introduced to support the Act by detailing the specific regulatory requirements necessary to maintain air safety standards. Under section 98 of the Act, the Governor-General is empowered to create regulations that are in the interests of the safety of air navigation. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for certain types of aircraft or aeronautical products. These directives, which are legislative instruments subject to disallowance, aim to ensure that aircraft remain airworthy as per international standards, particularly those set by the International Civil Aviation Organization (ICAO). The policy objective is to align Australian aviation safety practices with international obligations, thereby maintaining high safety standards across the global aviation network.

Scope and Application

The Civil Aviation Safety Regulations 1998, made under section 98 of the Civil Aviation Act 1988, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for types of aircraft or aeronautical products, with the aim of ensuring the safety of air navigation. These ADs serve as legislative instruments under the Acts Interpretation Act 1901 and are mandated by Australia's commitments under Annex 8 to the Convention on International Civil Aviation, which assigns the State of Design the responsibility for ensuring the continuing airworthiness of aircraft types. CASA, as Australia's national airworthiness authority, is tasked with assessing ADs issued by the State of Design and, when necessary, issuing corresponding Australian ADs to enforce the required measures. For instance, following the issuance of AD 2008-10-02 by the United States Federal Aviation Administration for specific Cessna aircraft models, CASA has issued Australian ADs listed in Schedule 1, effective from 13 May 2008. Given the international nature of these directives and their basis in international convention, these ADs were made without public consultation and do not require a Regulatory Impact Statement. The ADs were issued by the Manager, Systems and New Technologies in the Airworthiness Engineering Branch on behalf of CASA, in accordance with the Civil Aviation Act 1988.

Key Provisions

The Civil Aviation Act 1988 (section 98) allows the Governor-General to make regulations in the interest of air navigation safety, while regulation 39.001 of the Civil Aviation Safety Regulations 1998 grants the Civil Aviation Safety Authority (CASA) the authority to issue airworthiness directives (ADs) for certain types of aircraft and aeronautical products. These ADs are legislative instruments as per section 6 of the Legislative Instruments Act 2003, and they serve as the primary means for ensuring the continuing airworthiness of aircraft types as outlined in Annex 8 to the Convention on International Civil Aviation. The State of Design has the overarching responsibility for the continuing airworthiness of an aircraft type, and must provide necessary information to States of Registry to facilitate this. The obligations imposed by these ADs primarily fall on the State of Registry of individual aircraft, which must ensure the continuing airworthiness of the aircraft within their jurisdiction. When a State of Design issues an AD against a type of aircraft registered in Australia, CASA, as the national airworthiness authority, is obligated to assess this information and, if deemed necessary, issue corresponding Australian ADs. This ensures that the safety requirements set by the State of Design are enforced in Australia. Violations of airworthiness directives can lead to significant consequences. Under section 84A(2) of the Civil Aviation Act 1988, operators of affected aircraft must comply with ADs. Failure to adhere to these directives can result in severe penalties, including fines and imprisonment, as stipulated under the Act. Additionally, non-compliance with ADs can lead to the grounding of aircraft, which can severely impact both individual operators and the broader aviation industry. CASA enforces these regulations strictly to uphold the safety standards required under international aviation laws.
