AD/CESSNA 400/48 - Main Landing Gear Down Lock Pin and Set Screw - Inspection - CANCELLED

Overview

The Civil Aviation Act 1988 was enacted to provide a legal framework for civil aviation in Australia, ensuring the safety and efficiency of air navigation. This Act empowers the Governor-General to create regulations that align with the Act's safety objectives, as demonstrated by the Civil Aviation Safety Regulations 1998. These regulations empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. ADs are legislative instruments under the Acts Interpretation Act 1901, and they serve as a primary means of maintaining the continuing airworthiness of aircraft types, in line with the Convention on International Civil Aviation. The AD/CESSNA 400/48, affecting certain Cessna models, was issued by CASA but has since been cancelled due to Australia’s obligations under international aviation conventions, reflecting CASA's commitment to international safety standards. The cancellation of this AD did not require public consultation or a Regulatory Impact Statement, and it will take effect on 28 August 2008.

Scope and Application

The Civil Aviation Act 1988, together with the Civil Aviation Safety Regulations 1998, empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) that are applicable to kinds of aircraft or aeronautical products. These regulations are made in the interests of ensuring the safety of air navigation and are legislative instruments under the Legislative Instruments Act 2003. ADs, which serve as the primary means of communicating continuing airworthiness information, are issued in accordance with Annex 8 to the Convention on International Civil Aviation, where the State of Design holds overall responsibility for the continuing airworthiness of an aircraft type, while the State of Registry must ensure the continuing airworthiness of individual aircraft. CASA, or its predecessors, had previously issued an AD/CESSNA 400/48 affecting specific Cessna models, which has now been cancelled effective 28 August 2008, due to Australia's obligations under the Convention. This cancellation was made without public consultation and does not require a Regulatory Impact Statement, as determined by the Office of Best Practice Regulation. The AD was issued by the Manager, Airframes in the Airworthiness Engineering Branch, on behalf of CASA, in accordance with the Act.

Key Provisions

The key operative sections of the Civil Aviation Safety Regulations 1998, specifically regulation 39.001, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific kinds of aircraft or aeronautical products. These directives are instrumental in ensuring that the aircraft meet the required safety standards (39.001(5)). The ADs are considered legislative instruments under section 6 of the Legislative Instruments Act 2003, and they are subject to disallowance under section 46A of the Acts Interpretation Act 1901. The AD/CESSNA 400/48, which affected Cessna 401, 402, 411, 414 and 421 model aircraft, was issued by CASA or its predecessors. This directive has now been reviewed and cancelled, with the cancellation effective from 28 August 2008, and no replacement AD is required. Under the obligations set out in the Civil Aviation Safety Regulations 1998, CASA has the responsibility to issue ADs to ensure the continuing airworthiness of aircraft types. The State of Design has the overarching responsibility for the continuing airworthiness of an aircraft type, and must provide necessary information to the States of Registry. The State of Registry, in turn, must develop or adopt requirements to ensure the continuing airworthiness of the aircraft registered within its jurisdiction. This regulatory framework ensures that both the design and registry states play a role in maintaining the safety and airworthiness of aircraft. The cancellation of AD/CESSNA 400/48 is a result of Australia’s obligations under the Convention on International Civil Aviation, and as such, no public consultation has taken place. Additionally, the Office of Best Practice Regulation has determined that ADs do not require a Regulatory Impact Statement. The AD was made by the Manager, Airframes in the Airworthiness Engineering Branch, on behalf of CASA, in accordance with subsection 84A(2) of the Civil Aviation Act 1988. In terms of consequences, any breach of the regulations set out in the Civil Aviation Safety Regulations 1998 could lead to both civil and criminal liabilities. While the specific penalties are not outlined in the text, breaches of aviation safety regulations can result in significant penalties, including fines and imprisonment. The exact penalties would depend on the nature and severity of the breach, as well as any relevant case law. Failure to comply with ADs can result in severe consequences, including the potential grounding of aircraft and denial of access to Australian airspace. It is imperative for all parties involved to adhere to the ADs and other safety regulations to ensure the safety and airworthiness of aircraft. CASA's role in issuing and managing these directives is crucial in maintaining the highest safety standards in Australia's aviation industry.
