AD/CESSNA 400/13 - Propeller De-Ice Bolts - Inspection - CANCELLED

Overview

The Civil Aviation Act 1988 was enacted to regulate the safety of civil aviation within Australia and to ensure compliance with international standards set by the International Civil Aviation Organization (ICAO). It empowers the Governor-General to make regulations to maintain the safety of air navigation. Under this legislative framework, the Civil Aviation Safety Regulations 1998 were also established, allowing the Civil Aviation Safety Authority (CASA) to issue airworthiness directives for specific kinds of aircraft or aeronautical products to ensure their continued safety and airworthiness. The Civil Aviation Act 1988 and associated regulations reflect Australia's commitment to maintaining the highest safety standards in civil aviation, both domestically and in alignment with international obligations. In accordance with the provisions of the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998, CASA issued an airworthiness directive (AD) concerning Cessna 411 and 421 model aircraft, which has subsequently been reviewed and cancelled due to Australia's obligations under the Convention on International Civil Aviation. This cancellation was made by the Manager, Systems and New Technologies in the Airworthiness Engineering Branch on behalf of CASA, and it aligns with the requirement that ADs are legislative instruments subject to disallowance under the Acts Interpretation Act 1901. The cancellation of the AD reflects the State of Registry's responsibility for ensuring the continuing airworthiness of aircraft, and it was implemented without the need for a Regulatory Impact Statement or public consultation, as determined by the Office of Best Practice Regulation.

Scope and Application

The Civil Aviation Act 1988, in conjunction with the Civil Aviation Safety Regulations 1998, governs the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA). Specifically, regulation 39.001 allows CASA to issue ADs concerning specific types of aircraft or aeronautical products, thereby ensuring the safety of air navigation. The ADs are legislative instruments subject to disallowance under the Acts Interpretation Act 1901. The scope of these directives is grounded in international obligations under the Convention on International Civil Aviation, where the State of Design retains responsibility for the continuing airworthiness of an aircraft type, while the State of Registry must ensure the aircraft's ongoing airworthiness within its jurisdiction. CASA, acting within its regulatory authority, has the capacity to issue, review, and cancel ADs, as demonstrated by the cancellation of AD/CESSNA 400/13 concerning Cessna 411 and 421 models, effective from 28 August 2008. This cancellation reflects Australia's adherence to international civil aviation standards, obviating the need for public consultation or a Regulatory Impact Statement. The AD cancellation was authorised by the Manager, Systems and New Technologies in the Airworthiness Engineering Branch on behalf of CASA, in accordance with subsection 84A(2) of the Act.

Key Provisions

The Civil Aviation Act 1988, through section 98, empowers the Governor-General to establish regulations that serve the interests of air navigation safety. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 specifically authorises the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) concerning types of aircraft or aeronautical products. This regulatory framework ensures that aviation safety standards are maintained and enforced across the industry. Subregulation 39.001(5) further clarifies that ADs are considered disallowable instruments under section 46A of the Acts Interpretation Act 1901, thus qualifying them as legislative instruments in accordance with section 6 of the Legislative Instruments Act 2003. The obligations imposed by these regulations are primarily aimed at ensuring the continuing airworthiness of aircraft. Under 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, which includes providing necessary information to States of Registry to ensure compliance with airworthiness standards. Conversely, the State of Registry is tasked with developing or adopting specific requirements to maintain the airworthiness of individual aircraft registered within its jurisdiction. This division of responsibilities is integral to the global framework for aviation safety and ensures that both design and operational aspects of airworthiness are rigorously managed. CASA, as the governing body under these regulations, has issued and subsequently cancelled AD/CESSNA 400/13, which previously affected Cessna 411 and 421 model aircraft. The cancellation of this AD, effective from 28 August 2008, was necessitated by Australia's international obligations under the Convention on International Civil Aviation. As a result, there was no public consultation required on this cancellation, and the Office of Best Practice Regulation has determined that ADs do not necessitate a Regulatory Impact Statement. The decision to cancel the AD was made by the Manager, Systems and New Technologies in the Airworthiness Engineering Branch of CASA, in accordance with subsection 84A(2) of the Act. Regarding the consequences of breaching these regulations, it is important to note that ADs are legally binding. Failure to comply with an airworthiness directive can lead to severe civil and criminal penalties. Under the Civil Aviation Act 1988, non-compliance may result in fines and imprisonment, with the specific penalties varying depending on the severity and nature of the breach. Additionally, the operational certification of the aircraft may be revoked, which can have significant financial and operational repercussions for the aircraft operator. The stringent enforcement of these regulations underscores the critical importance of maintaining airworthiness to ensure the safety of all aviation activities.
