AD/PC-6/15 - Aileron Cable Pulley - Modification

Overview

The Civil Aviation Regulations 1998, enacted by the Commonwealth Parliament, form a fundamental component of Australia's aviation safety framework. One specific aspect of this legislation is the Airworthiness Directives (ADs) which ensure that aircraft are maintained in a safe and airworthy condition. AD/PC-6/15, issued under Part 39, pertains specifically to the Pilatus Porter PC-6 Series Aeroplanes, targeting a critical issue with the aileron cable pulley for all models prior to serial number 633. The directive mandates compliance before 31 March 1967, as outlined in Pilatus Service Bulletin No. 68, aiming to address potential safety risks associated with the identified component. This regulatory measure underscores the Civil Aviation Safety Authority's commitment to maintaining the highest safety standards in the aviation industry.

Scope and Application

The Civil Aviation Regulations 1998, specifically PART 39 - 105, pertains to the Civil Aviation Safety Authority's (CASA) Schedule of Airworthiness Directives for Pilatus Porter PC-6 Series Aeroplanes. This regulation applies to all models of the Pilatus Porter PC-6 Series aeroplanes with serial numbers prior to 633, mandating a modification to the aileron cable pulley as outlined in Pilatus Service Bulletin No. 68. Compliance with this directive is mandatory and must be achieved before 31 March 1967. The regulation ensures that all applicable aircraft meet specific safety standards set forth by CASA, impacting the operational safety and airworthiness of these aircraft within Australia's jurisdiction. The regulation is enforceable across the Commonwealth, ensuring uniform safety standards are adhered to by all entities operating these aircraft within Australian airspace.

Key Provisions

The main operative sections of the Civil Aviation Regulations 1998 (CAR) pertaining to the Pilatus Porter PC-6 Series Aeroplanes focus on ensuring the airworthiness of these aircraft models through specific directives. Section 39-105 of the CAR, which pertains to Airworthiness Directives, mandates that the specified models of the Pilatus Porter must comply with the directive AD/PC-6/15. This directive, documented as Pilatus SB No. 68, requires the modification of the aileron cable pulley for all models prior to serial number 633 to be completed before 31 March 1967. The directive is critical in addressing potential safety issues and ensuring the continued safe operation of these aircraft. The obligations imposed by the CAR on the parties or entities governed by this legislation are quite specific. Operators of the Pilatus Porter PC-6 Series Aeroplanes must ensure that the aileron cable pulley modifications are carried out as per the requirements set out in the directive. This involves adhering to the timeline provided, ensuring that the necessary modifications are completed before the specified date. Operators must also maintain records of compliance with this directive, which may be required for inspection by the Civil Aviation Safety Authority (CASA). Failure to comply with these requirements can result in significant repercussions for the operator. Breaching the requirements of the CAR can lead to various consequences, including both civil and criminal penalties. Under section 91 of the Civil Aviation Act 1988, any person who fails to comply with an Airworthiness Directive may be subject to enforcement action. Civil penalties for non-compliance can include fines, and in more severe cases, criminal penalties may apply. The maximum penalties for such breaches are detailed within the Act and can include substantial fines or imprisonment, depending on the severity and frequency of the violation. It is crucial for operators to adhere to the directives to avoid these potential legal consequences.
