Overview

The Civil Aviation Regulations 1998, amended by the Legislative instrument F2006B04869, was enacted to ensure the safety and compliance of civil aviation operations within Australia. This particular legislative amendment, introduced by the Civil Aviation Safety Authority (CASA), addresses the need for rigorous inspection protocols for the flap control systems in CASA 212 series aeroplanes. The primary objective is to maintain the structural integrity of these systems, mitigating risks associated with damage tolerance as identified in prior analyses. The requirement is to inspect the flap control system in accordance with CASA document COM. 212-206 Revision 1, ensuring compliance by conducting inspections before accumulating 20,000 flights or within 2,000 flights after 5 October 1989, and subsequently at intervals specified in the requirement document. This legislative update rectifies an inspection interval error in the original Airworthiness Directive, underscoring the commitment to safety through precise and timely maintenance procedures. The regulatory framework aims to prevent potential failures in the flap control system, thereby enhancing the overall safety standards of civil aviation operations in Australia.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, governs the safety and airworthiness of aircraft operating within Australia. The legislative instrument F2006B04869, which amends AD/CASA/13, applies to all models of Casa 212 Series Aeroplanes. The regulation mandates inspections of the flap control system to ensure continued safety and compliance with airworthiness standards. This requirement applies to any person or entity operating Casa 212 Series Aeroplanes within Australian airspace or under the jurisdiction of the Civil Aviation Safety Authority. The scope of the regulation is confined to the specified models of aeroplanes and does not extend to other aircraft types or components outside the flap control system. The inspections must be carried out in accordance with the specified Casa document and the procedures outlined in the C212 Non Destructive Inspection Manual, with a specific emphasis on meeting the inspection timelines and intervals detailed in the Requirement Document. Compliance is necessary prior to reaching 20,000 flights or within 2,000 flights after 5 October 1989, whichever is later, and then at the intervals prescribed in the Requirement Document. The regulation does not explicitly mention any exclusions, exemptions, or thresholds beyond the specified inspection requirements.

Key Provisions

The Civil Aviation Safety Authority (CASA) has issued an airworthiness directive (AD) under Part 39 of the Civil Aviation Regulations 1998 (section 39-105) to ensure the safety of CASA 212 Series Aeroplanes. This directive mandates specific inspections of the flap control system, as outlined in CASA document COM. 212-206 Revision 1, dated 20 May 1988, and further detailed in the C212 Non Destructive Inspection Manual (sections 27-50-01 to 27-50-05). These inspections are essential for maintaining the structural integrity of the aeroplanes, especially as they approach and exceed their original design life. The AD requires that the flap control system be inspected prior to reaching 20,000 flights or within 2,000 flights after 5 October 1989, whichever occurs later. Subsequent inspections must then follow the intervals specified in the Requirement Document. This directive applies to all models within the CASA 212 Series. Compliance with these inspection requirements is mandatory, and failure to adhere to the prescribed schedule can result in significant safety risks. Operators of CASA 212 Series Aeroplanes must ensure that all inspections are conducted by qualified personnel following the specified procedures. This includes using the acceptable methods detailed in the C212 Non Destructive Inspection Manual. It is crucial that records of all inspections are maintained and readily available for review by CASA inspectors. The directive also necessitates that any identified issues are promptly addressed and rectified according to the procedures outlined in the CASA documents. Failure to comply with the requirements of this airworthiness directive can result in serious safety implications. CASA has the authority to take enforcement actions against operators who do not adhere to the inspection schedule and procedures. Potential consequences include grounding of the aircraft, fines, and other regulatory actions. The severity of these penalties reflects the importance of maintaining the structural integrity of the flap control system as a critical safety measure. The directive also highlights that damage tolerance analyses have identified the flap control system as potentially critical. Thus, regular and rigorous inspections are necessary to ensure continued airworthiness. Amendment 1 to the original AD corrects an error in the inspection intervals, underscoring the need for precision in following the mandated procedures. Operators must remain vigilant and proactive in their compliance efforts to avoid any breaches that could lead to enforcement actions.
