AD/PA-23/10 - Wing Front Spar Attachment Fitting - Reinforcement

Overview

The Civil Aviation Regulations 1998, amended by the Civil Aviation Amendment (Enhancing Safety and Security) Regulations 2006, were enacted to ensure the safety and security of civil aviation within Australia. This legislative instrument, particularly PART 39 - 105, establishes the Civil Aviation Safety Authority's (CASA) schedule of airworthiness directives which are crucial in maintaining the safety standards of aircraft operating in Australia. The policy objective of these regulations is to ensure that aircraft are maintained in a safe and airworthy condition, thereby protecting the public and enhancing the overall safety of the aviation industry. One such directive, AD/PA-23/10, specifically addresses the reinforcement of the wing front spar attachment fitting for Piper PA-23 (Apache and Aztec) series aeroplanes, ensuring these aircraft meet the required safety standards to prevent potential structural failures.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, as amended, mandates certain airworthiness directives to ensure the safety and compliance of aircraft operating within Australia. One such directive, AD/PA-23/10, pertains to the reinforcement of the wing front spar attachment fitting for Piper PA-23 (Apache and Aztec) series aeroplanes. This directive applies to aircraft with serial numbers prior to 23-322, as referenced in Piper Service Bulletin No. 142 or Federal Aviation Administration Advisory Directive 55-21-2. The directive mandates that compliance must be achieved forthwith, ensuring that the specified modifications are implemented without delay to maintain the airworthiness of the affected aircraft. The geographic reach of this regulation is national, applying to all aircraft registered in Australia, regardless of the location of operation within the Commonwealth. There are no stated exclusions, exemptions, or thresholds within the text, and the application is direct and comprehensive for the specified models and serial numbers.

Key Provisions

The Civil Aviation Regulations 1998, Part 39 - 105, outlines specific airworthiness directives for certain aircraft, including the Piper PA-23 (Apache and Aztec) Series Aeroplanes, as detailed in AD/PA-23/10 (sections 39-105 and AD/PA-23/10). This directive primarily focuses on reinforcing the wing front spar attachment fitting for models with serial numbers prior to 23-322. The reinforcement requirement is specified in Piper Service Bulletin No. 142 or FAA AD 55-21-2. Compliance with this directive is mandatory and must be carried out immediately. Entities and operators of the affected Piper PA-23 aircraft must ensure that the wing front spar attachment fittings are reinforced according to the specified bulletins. This involves implementing the necessary modifications as detailed in the service bulletins to address the structural integrity of the wing attachment points. These modifications are critical for maintaining the airworthiness of the aircraft and ensuring safety during operation. Failing to comply with the requirements set out in AD/PA-23/10 can result in serious legal and safety implications. The Civil Aviation Safety Authority (CASA) may take enforcement actions against non-compliant aircraft, which can include grounding the aircraft until the necessary modifications are made. Additionally, operators may face financial penalties, and in severe cases, criminal charges could be brought against responsible individuals or entities for operating non-compliant aircraft. The exact penalties are not specified in the provided text but can include substantial fines and other regulatory sanctions under the Civil Aviation Act 1988.
