AD/PC-6/2 - Propeller Pitch Control - Inspection

Overview

The Civil Aviation Regulations 1998, enacted by the Australian Government, serve as a comprehensive regulatory framework for ensuring the safety and efficiency of civil aviation activities within Australia. Among the various parts of these regulations, Part 39 - 105, which pertains to the Civil Aviation Safety Authority's (CASA) Schedule of Airworthiness Directives, plays a crucial role in maintaining aircraft safety standards. One such directive, AD/PC-6/2, specifically targets Pilatus Porter PC-6 Series Aeroplanes by mandating inspections of the propeller pitch control system. This directive was introduced to address safety concerns related to the propeller pitch control in these aircraft models, ensuring that all PC-6/A and PC-6/A-H2 aircraft comply with stringent safety standards as outlined in Pilatus Service Bulletin No. 45. The policy objective of this regulation is to enhance aviation safety by proactively identifying and rectifying potential issues in the aircraft's critical systems.

Scope and Application

The Civil Aviation Regulations 1998, as amended, under Part 39 - 105, establish the Civil Aviation Safety Authority (CASA) schedule of airworthiness directives, which includes specific directives for aircraft models such as the Pilatus Porter PC-6 Series Aeroplanes. This particular legislation applies to all models of the PC-6/A and PC-6/A-H2 series, mandating compliance with airworthiness directives to ensure safety standards are met. The legislation encompasses all entities operating these aircraft within Australian airspace, thereby enforcing strict regulatory measures to maintain air safety. The directive in question, AD/PC-6/2, pertains specifically to the inspection of the propeller pitch control system, referencing Pilatus Service Bulletin No. 45 for compliance details. While the regulations are comprehensive, certain exclusions or exemptions may be detailed in subordinate instruments or specific CASA directives, which further refine the scope and application of these safety measures.

Key Provisions

The Civil Aviation Regulations 1998, under Part 39 - 105, specifically address the airworthiness directives for Pilatus Porter PC-6 Series aeroplanes. Section 3/66 of this regulation concerns the inspection of propeller pitch control for models PC-6/A and PC-6/A-H2 (39-105.3/66). This directive mandates that all relevant aircraft must undergo inspections as specified in Pilatus Service Bulletin No. 45 (39-105.3/66). Compliance with these inspections is crucial to ensure the safe operation of the aircraft, as the directive requires adherence to the detailed requirements outlined in the referenced document. The obligations imposed by this directive are straightforward but critical. Owners and operators of the specified Pilatus Porter models must ensure that the propeller pitch control system is inspected according to the instructions provided in Pilatus SB No. 45 (39-105.3/66). This includes performing the necessary checks and maintenance tasks to ensure that the propeller pitch control operates correctly and safely. Failure to comply with these inspection requirements can lead to significant safety issues, potentially resulting in the grounding of the aircraft until the necessary inspections and repairs are completed. Failure to adhere to the inspection requirements outlined in the directive can lead to serious consequences. Under the Civil Aviation Act 1988, non-compliance may result in enforcement actions by the Civil Aviation Safety Authority (CASA). For individuals, this could mean fines of up to $16,500 for each flight conducted in non-compliance (39-105.3/66). For corporations, the fines can be significantly higher, with penalties up to $82,500 for each flight. Additionally, non-compliance may result in operational restrictions, such as the suspension of an operator’s certificate or the grounding of the affected aircraft until the required inspections are satisfactorily completed. These penalties and consequences underscore the importance of strict adherence to the airworthiness directives to maintain safety standards in aviation.
