AD/CESSNA 207/18 - Ammeter Type and Position - CANCELLED

Overview

The Civil Aviation Act 1988, enacted by the Parliament of Australia, was established to regulate civil aviation in Australia and ensure the safety of air navigation. This Act empowers the Governor-General to create regulations that promote the safety of air navigation, and these regulations are enforced by the Civil Aviation Safety Authority (CASA). The Civil Aviation Safety Regulations 1998 further detail the specific requirements and procedures for ensuring the safety of aircraft and aeronautical products, including the issuance of airworthiness directives (ADs). Regulation 39.001 allows CASA to issue ADs, which are legislative instruments that mandate safety requirements for particular aircraft types or aeronautical products. The policy objective of these regulations is to maintain the highest safety standards in civil aviation by ensuring that aircraft remain airworthy and comply with safety directives. In line with the Convention on International Civil Aviation, the State of Design has the overarching responsibility for the continuing airworthiness of aircraft types, and must provide necessary information to ensure their airworthiness. The State of Registry, in this case CASA, must assess this information and, if appropriate, issue corresponding ADs to enforce these requirements. In accordance with these obligations, CASA issued and subsequently cancelled Australian AD/CESSNA 207/18 for all models of Cessna 207 series aeroplanes, effective from 25 September 2008. No public consultation or Regulatory Impact Statement was required as the cancellation aligns with international obligations and the unsafe condition no longer exists. This AD was issued by the Manager, Systems and New Technologies, in the Airworthiness Engineering Group, on behalf of CASA, in accordance with subsection 84A(2) of the Act.

Scope and Application

The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide the framework for issuing airworthiness directives (ADs) to ensure the safety of air navigation. Specifically, regulation 39.001 of the Civil Aviation Safety Regulations 1998 empowers the Civil Aviation Safety Authority (CASA) to issue ADs for certain types of aircraft or aeronautical products. These ADs are legislative instruments that are subject to disallowance and are made under the authority conferred by the Civil Aviation Act 1988. They are issued to address issues that impact the continuing airworthiness of aircraft and are in compliance with international standards set forth in Annex 8 to the Convention on International Civil Aviation. The State of Design has the primary responsibility for the airworthiness of aircraft types, while the State of Registry, in this case CASA, must ensure that any issued ADs are appropriately assessed and, if necessary, adopted as Australian ADs. In the case of the Cessna 207 series aeroplanes, CASA assessed an existing AD and decided to cancel it, effective from 25 September 2008, as the unsafe condition it addressed no longer exists. No public consultation or regulatory impact statement was required for this action.

Key Provisions

The Civil Aviation Act 1988 provides the legal framework for aviation safety in Australia, with specific reference to airworthiness directives under section 98. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives for specified aircraft or aeronautical products. These directives are legislative instruments, as outlined in subregulation 39.001(5), and they are critical tools for ensuring the continuing airworthiness of aircraft. Under international standards set by Annex 8 to the Convention on International Civil Aviation, the State of Design is responsible for the airworthiness of a particular aircraft type, while the State of Registry (in this case, Australia) is tasked with ensuring the ongoing airworthiness of individual aircraft. CASA, as the national airworthiness authority, must assess any airworthiness directives issued by the State of Design and, if necessary, issue corresponding directives for Australian-registered aircraft. For instance, CASA issued and subsequently cancelled Australian AD/CESSNA 207/18 for all models of Cessna 207 series aeroplanes, reflecting the resolution of the unsafe condition that initially prompted the directive. The obligations imposed by the Civil Aviation Safety Regulations 1998 on CASA and other entities primarily revolve around the assessment, issuance, and monitoring of airworthiness directives. CASA must rigorously evaluate information provided by the State of Design and determine whether Australian-registered aircraft are affected. If the unsafe condition identified in the directive is applicable to Australian aircraft, CASA must issue a corresponding airworthiness directive. Furthermore, CASA is obligated to maintain continuous communication with the State of Design and other relevant international authorities to ensure that Australian aviation safety standards are aligned with international best practices. The cancellation of Australian AD/CESSNA 207/18 due to the resolution of the unsafe condition exemplifies CASA's commitment to these obligations. In terms of consequences for non-compliance, the Civil Aviation Safety Regulations 1998 do not explicitly outline specific offences or penalties related to the issuance or failure to comply with airworthiness directives. However, non-compliance with CASA directives can lead to significant legal and operational repercussions. For example, operating an aircraft that does not meet the requirements of an applicable airworthiness directive can result in enforcement actions, including fines, suspension or revocation of air operator certificates, and potential criminal charges if the non-compliance leads to an accident or serious incident. The overarching goal is to ensure that all parties adhere to the safety standards set forth to maintain the highest level of aviation safety.
