Overview
The Civil Aviation Regulations 1998, specifically Part 39, includes the Airworthiness Directive (AD) AD/CESSNA 150/43, which was introduced to address discrepancies in repairs carried out by Capricorn Aircraft Repair on Cessna 150, F150, 152 & F152 series aeroplanes. This legislative instrument was enacted to ensure that aircraft repaired by Capricorn Aircraft Repair between 2 December 1985 and 29 November 1990 comply with approved data and specifications, particularly regarding the use of identical or approved replacement components. The policy objective of this directive is to maintain the airworthiness of affected aircraft by rectifying any deficiencies identified during inspection. Compliance with this directive must be achieved at the next scheduled maintenance inspection after 21 March 1991, with any non-compliant aircraft required to have deficiencies rectified before further flight, and the Civil Aviation Safety Authority must be informed of inspected aircraft.
Scope and Application
The Civil Aviation Regulations 1998, specifically PART 39 - 105, apply to all aircraft of the Cessna 150, F150, 152, and F152 series that have undergone repair by Capricorn Aircraft Repair in Thangool, Queensland, between 2 December 1985 and 29 November 1990. This regulation mandates that these aircraft be inspected to ascertain whether the repairs were conducted in accordance with approved data and whether the replacement components used are either identical to the original components or approved as suitable replacements. Aircraft failing to meet these criteria must have their deficiencies rectified before further flight, and the Civil Aviation Safety Authority must be notified of the inspection outcomes. Compliance with these directives must be achieved at the next scheduled maintenance inspection following 21 March 1991. This regulation is geographically confined to Australia and is enforced by the Civil Aviation Safety Authority, with the requirement extending to ensure the safety and airworthiness of the specified aircraft.
Key Provisions
The main provisions of the AD/CESSNA 150/43 under the Civil Aviation Regulations 1998 (sections referenced in parentheses) require an inspection of all Cessna 150, F150, 152 & F152 series aeroplanes that were repaired by Capricorn Aircraft Repair in Thangool, Queensland, between 2 December 1985 and 29 November 1990. The inspection must determine if these repairs were carried out using approved data and whether the replacement components used are identical to the originals or are approved replacements. Aircraft that do not meet these criteria must have any deficiencies rectified before further flight (sections 1 and 3).
The obligations imposed by this directive include conducting a thorough inspection of the specified aircraft to verify that the repairs were performed according to approved data and that the replacement parts used are approved. Additionally, any aircraft found to have deficiencies must have these issues addressed promptly to ensure continued airworthiness. It is also mandatory to inform the Civil Aviation Safety Authority (CASA) of any aircraft inspected as a result of this directive (section 3).
Failure to comply with the requirements of this directive can lead to significant consequences. If an aircraft is found to have been repaired using unapproved data or non-identical components, it may be grounded until the deficiencies are rectified. The operator of the aircraft may face penalties for non-compliance, and CASA has the authority to take enforcement actions to ensure safety standards are met. The specific penalties for non-compliance are not detailed in the directive but may include fines, suspension of operations, or other regulatory actions (section 4).
