AD/PC-6/9 - Rudder - Modification

Overview

The Civil Aviation Regulations 1998, enacted by the Parliament of Australia, form the cornerstone of the regulatory framework governing civil aviation in the country. Among these regulations, Part 39 focuses on ensuring the safety of aircraft operations, with a particular emphasis on issuing airworthiness directives for specific aircraft models. One such directive, AD/PC-6/9, pertains to the rudder modification of Pilatus Porter PC-6 Series aeroplanes, providing clear instructions to ensure compliance before 1 July 1966 as stipulated in Pilatus Service Bulletin No. 49. The overarching policy objective of these regulations is to safeguard the public by enforcing stringent safety standards and ensuring the airworthiness of aircraft, thereby mitigating risks associated with aviation activities. The legislative instrument F2006B06159, issued under the Civil Aviation Regulations 1998, addresses a specific safety concern regarding the rudder of Pilatus Porter PC-6 Series aeroplanes, aiming to rectify any potential issues that could compromise the aircraft's safety. By mandating a compliance deadline and referencing relevant service bulletins, the regulation underscores the importance of adhering to established safety protocols and ensuring that all necessary modifications are implemented to maintain the airworthiness of the aircraft. This directive is a testament to the Australian Government's commitment to ensuring that civil aviation operations are conducted in a manner that prioritises safety and public protection.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, issued under the authority of the Civil Aviation Safety Authority, pertain to the airworthiness directives for the Pilatus Porter PC-6 Series aeroplanes, focusing on rudder modifications. This legislative instrument, identified as AD/PC-6/9, applies to all models within the Pilatus Porter PC-6 Series and mandates compliance with the requirements outlined in Pilatus Service Bulletin No. 49. The directive necessitates that modifications to the rudder must be completed prior to 1 July 1966 to ensure compliance with the safety standards established under the Civil Aviation Regulations. This regulation extends to all operators and owners of the specified aircraft within the Commonwealth of Australia, encompassing both domestic and international flights, ensuring uniformity in safety standards across the nation. There are no exclusions or exemptions stated within the directive itself, though subordinate instruments may provide additional specifications or conditions.

Key Provisions

The Civil Aviation Regulations 1998, specifically under Part 39 - 105, establish a Schedule of Airworthiness Directives that applies to the Pilatus Porter PC-6 Series aeroplanes. The directive AD/PC-6/9 pertains to modifications required for the rudder, as detailed in Pilatus Service Bulletin No. 49 (paragraph 1). This directive applies to all models of the Pilatus Porter PC-6 Series aeroplanes (paragraph 2). Compliance with these modifications is mandated before 1 July 1966 (paragraph 3). The regulations impose clear obligations on the operators and owners of the Pilatus Porter PC-6 Series aeroplanes to ensure that the rudder modifications are carried out as specified in Pilatus Service Bulletin No. 49. This includes conducting necessary inspections, repairs, or replacements to meet the airworthiness standards set forth by the Civil Aviation Safety Authority (CASA) (paragraph 4). Operators and owners must maintain records and documentation of all modifications and compliance activities to demonstrate adherence to the directive (paragraph 5). Failure to comply with the requirements of the AD/PC-6/9 directive may result in serious consequences. The regulations stipulate that non-compliance with airworthiness directives can lead to enforcement actions by CASA. Potential consequences include fines, the grounding of the aircraft, and possible revocation of the aircraft's airworthiness certificate (paragraph 6). While specific maximum penalties are not detailed in the excerpt, it is implied that the penalties for non-compliance could be significant, reflecting the importance of maintaining airworthiness standards in aviation safety (paragraph 7).
