AD/CESSNA 400/56 - Upper Inner Cabin Door Handle and Locking Mechanism - Inspection - CANCELLED

Overview

The Civil Aviation Act 1988 was enacted to ensure the safety of air navigation in Australia, and it empowers the Governor-General to create regulations that further this aim. One such regulation is found in the Civil Aviation Safety Regulations 1998, specifically regulation 39.001, which allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives for specific types of aircraft and aeronautical products. As stipulated in subregulation 39.001(5), these directives are classified as disallowable instruments under the Acts Interpretation Act 1901, and thus are considered legislative instruments in accordance with section 6 of the Legislative Instruments Act 2003. The Civil Aviation Act 1988, administered by the Australian Parliament, aims to enhance the safety and efficiency of civil aviation within Australia by establishing a comprehensive regulatory framework. In accordance with Annex 8 of the Convention on International Civil Aviation, the State of Design is responsible for the continuing airworthiness of an aircraft type, while the State of Registry is responsible for the continuing airworthiness of individual aircraft. Airworthiness directives, which are issued by most ICAO Contracting States, are the primary means of communicating continuing airworthiness information. CASA, in its role as the national regulator, has issued and subsequently cancelled AD/CESSNA 400/56, which affected Cessna 402, 404, 414, and 421 model aircraft. The cancellation of this directive, effective from 28 August 2008, is a result of Australia’s obligations under the Convention on International Civil Aviation, and as such, no public consultation was required. Additionally, the Office of Best Practice Regulation has concluded that airworthiness directives do not necessitate a Regulatory Impact Statement. This directive was issued by the Manager, Airframes, in the Airworthiness Engineering Branch on behalf of CASA, in compliance with subsection 84A(2) of the Act.

Scope and Application

The Civil Aviation Act 1988, complemented by the Civil Aviation Safety Regulations 1998, provides the legislative framework for ensuring the safety of air navigation in Australia. Specifically, regulation 39.001 of the Civil Aviation Safety Regulations 1998 empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for various types of aircraft or aeronautical products. These directives are considered disallowable instruments under section 46A of the Acts Interpretation Act 1901 and are recognised as legislative instruments pursuant to section 6 of the Legislative Instruments Act 2003. ADs play a crucial role in maintaining the continuing airworthiness of aircraft, a responsibility that is shared between the State of Design and the State of Registry, as outlined in Annex 8 to the Convention on International Civil Aviation. CASA, acting on behalf of the State of Registry, has issued, reviewed, and subsequently cancelled AD/CESSNA 400/56, which affected Cessna 402, 404, 414, and 421 model aircraft. This cancellation, which will take effect on 28 August 2008, was made without public consultation due to Australia's international obligations under the Convention on International Civil Aviation, and no Regulatory Impact Statement was required as determined by the Office of Best Practice Regulation. The AD was issued by the Manager, Airframes in the Airworthiness Engineering Branch of CASA, in accordance with subsection 84A(2) of the Act.

Key Provisions

Under the Civil Aviation Act 1988, the Governor-General has the authority to establish regulations that are essential for ensuring the safety of air navigation (section 98). Specifically, regulation 39.001 of the Civil Aviation Safety Regulations 1998 empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) concerning certain types of aircraft or aeronautical products. It is crucial to note that these ADs are considered disallowable instruments under section 46A of the Acts Interpretation Act 1901, and therefore, they are legislative instruments as defined by section 6 of the Legislative Instruments Act 2003 (subregulation 39.001(5)). The ADs serve as a primary means for ensuring the continuing airworthiness of aircraft types, as outlined in Annex 8 of the Convention on International Civil Aviation. The State of Design holds primary responsibility for the continuing airworthiness of an aircraft type and must provide necessary information to the State of Registry to facilitate this. The State of Registry, in turn, must implement or adopt measures to ensure the continuing airworthiness of individual aircraft. In line with these international obligations, CASA has issued, reviewed, and subsequently cancelled AD/CESSNA 400/56, which affected Cessna 402, 404, 414, and 421 model aircraft. This cancellation will take effect on 28 August 2008, and no replacement AD is deemed necessary. The obligations imposed by the Civil Aviation Safety Regulations 1998 require CASA to issue ADs that ensure the continuing airworthiness of specified aircraft types. The State of Registry must ensure that aircraft under its jurisdiction comply with these ADs, while the State of Design is responsible for providing the necessary information to support this compliance. Given Australia’s commitments under the Convention on International Civil Aviation, CASA has acted in accordance with subsection 84A(2) of the Act in cancelling the aforementioned AD. In terms of potential consequences, any breach of the ADs could lead to significant safety risks, which might result in enforcement actions by CASA. While the Civil Aviation Safety Regulations 1998 do not explicitly outline penalties for non-compliance with ADs, failure to adhere to these directives could lead to actions under the Civil Aviation Act 1988, including fines and potential criminal charges for serious breaches. The specific penalties would depend on the nature and severity of the non-compliance.
