Overview
The Civil Aviation Regulations 1998, enacted by the Australian Government, contain provisions designed to ensure the safety and reliability of aircraft operating within Australia. One such provision, specifically AD/CESSNA 180/73, addresses the safety concerns arising from discrepancies in repairs carried out by Capricorn Aircraft Repair of Thangool, Queensland, between 2 December 1985 and 29 November 1990, on Cessna 180, 182, and Wren 460 Series aeroplanes. This directive was introduced to rectify issues identified in the structural repair data and replacement components used in the repairs, ensuring compliance with approved data and specifications. The policy objective of this directive is to maintain the airworthiness of the affected aircraft by requiring inspections and rectifying any deficiencies before further flights, thus ensuring the safety and reliability of the aircraft in operation.
Scope and Application
The Civil Aviation Regulations 1998, specifically Part 39 - 105, addresses the safety and airworthiness of aircraft repaired by designated entities within defined periods. For the Cessna 180, 182, and Wren 460 series aeroplanes, the Airworthiness Directive AD/CESSNA 180/73 pertains to aircraft repaired by Capricorn Aircraft Repair, located in Thangool, Queensland, between 2 December 1985 and 29 November 1990. The directive requires an inspection to ascertain if these repairs were conducted in accordance with approved data and whether the replacement components used match the originals or are approved alternatives. Aircraft failing to meet these standards must rectify any deficiencies before further flight. Additionally, the Civil Aviation Safety Authority must be notified of any inspections conducted pursuant to this directive. Compliance is mandatory at the next scheduled maintenance inspection following 21 March 1991. This legislation underscores the importance of maintaining stringent safety standards in the aviation industry by ensuring that repairs are performed with approved data and components.
Key Provisions
The Civil Aviation Regulations 1998, specifically in Part 39, Section 105, establish Airworthiness Directives (ADs) aimed at ensuring the safety and airworthiness of certain aircraft. In this case, AD/CESSNA 180/73 targets Cessna 180, 182, and Wren 460 Series Aeroplanes that have undergone repairs by Capricorn Aircraft Repair in Thangool, QLD, between 2 December 1985 and 29 November 1990. This directive mandates that all affected aircraft must be inspected to verify whether the repairs were conducted in accordance with approved data, and if so, whether the replacement components used were either identical to the original components or approved as replacements.
The obligation imposed by this directive requires the inspection and assessment of the aircraft to determine compliance with the approved repair data and component specifications. This inspection must be performed on all aircraft that were repaired by Capricorn Aircraft Repair during the specified period. Notably, any aircraft found to have been repaired using unapproved data or non-identical, non-approved components must have these deficiencies rectified before further flight. Additionally, the Civil Aviation Safety Authority (CASA) must be informed of any inspections conducted as a result of this directive. This compliance is to be achieved at the next scheduled inspection for Maintenance Release following 21 March 1991.
The directive carries potential consequences for non-compliance. If an aircraft is found not to meet the requirements stipulated in AD/CESSNA 180/73, it must be brought into compliance by rectifying any deficiencies identified during the inspection. Failure to comply with these directives can result in the aircraft being grounded until the necessary repairs and inspections are completed. Additionally, CASA must be notified of the inspection outcomes, and any discrepancies must be addressed promptly to ensure the continued airworthiness of the aircraft. The regulations underscore the importance of adhering to approved data and component specifications to maintain the safety and integrity of the aircraft in operation.
