AD/PA-31/52 - Replacement of Radio Power Relay Cover Spacer Bushings

Overview

The Civil Aviation Regulations 1998, enacted by the Parliament of Australia, were established to regulate the safety standards of civil aviation in the country. The 1998 Regulations included amendments to address evolving safety concerns and technological advancements in the aviation industry. Part 39, specifically 105, of these regulations pertains to the Civil Aviation Safety Authority (CASA) Schedule of Airworthiness Directives, which mandate safety improvements and compliance for specific aircraft types. This legislation is integral to maintaining the safety and reliability of aircraft operating within Australia's airspace. The policy objective of these regulations is to ensure that all civil aviation activities comply with stringent safety standards to protect passengers, crew, and the general public. One specific example is the Airworthiness Directive AD/PA-31/52 concerning the Piper PA-31 series aeroplanes, which requires the replacement of radio power relay cover spacer bushings for certain serial numbers. This directive was issued to address identified safety risks and ensure the continued airworthiness of affected aircraft. Compliance with such directives is mandatory and must be achieved within specified timeframes to maintain operational safety.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, establish the Civil Aviation Safety Authority (CASA) Schedule of Airworthiness Directives concerning Piper PA-31 Series aeroplanes. This directive mandates the replacement of radio power relay cover spacer bushings for certain models and serial numbers of Piper PA-31 aircraft. The directive applies to all model PA-31, PA-31-325, and PA-31-350 aeroplanes with the specified serial numbers. The requirement to comply with this directive must be fulfilled within 10 hours of time in service after the effective date of 18 January 1977, as referenced in Piper Service Bulletin No. 535. This legislation applies to the specific identified aircraft models within the Commonwealth of Australia, ensuring compliance with CASA standards for airworthiness and safety.

Key Provisions

The Civil Aviation Regulations 1998, particularly Part 39, Section 105, includes an Airworthiness Directive (AD) relating to the Piper PA-31 series aeroplanes (sections 39-105). Specifically, AD/PA-31/52 mandates the replacement of radio power relay cover spacer bushings for certain model aeroplanes. This directive applies to all model PA-31, PA-31-325, and PA-31-350 with specific serial numbers, as detailed in the document. The compliance requirement is that these modifications must be completed within 10 hours of time in service following 18 January 1977. The AD imposes specific obligations on the operators or owners of the affected aircraft. These obligations include ensuring that the specified modifications are carried out by a licensed aircraft maintenance engineer within the stipulated timeframe. Failure to comply with these requirements could result in the aircraft being deemed unairworthy, potentially leading to grounding and further regulatory scrutiny. Breach of the AD/PA-31/52 requirements can have significant consequences. Civil aviation regulations are stringent, and non-compliance can lead to enforcement actions by the Civil Aviation Safety Authority (CASA). The penalties for not adhering to an AD can include fines, suspension or revocation of aircraft operating certificates, and in severe cases, criminal charges. The exact penalties depend on the severity and frequency of the non-compliance, but they can be substantial, reflecting the importance of maintaining airworthiness standards for public safety.
