AD/PA-23/3 - Main Landing Gear Forgings and Wheels - Replacement

Overview

The Civil Aviation Regulations 1998, specifically Part 39 - 105, introduced by the Commonwealth of Australia to regulate civil aviation safety, was enacted to ensure the safe operation of aircraft within Australian airspace. This legislative instrument, F2006B05459, addresses specific safety concerns pertaining to the Piper PA-23 (Apache and Aztec) series aeroplanes, particularly focusing on the main landing gear forgings and wheels. This was necessitated by identified safety risks that required immediate action to mitigate potential hazards. The enactment was overseen by the Civil Aviation Safety Authority (CASA), with the policy objective being to enhance aviation safety by mandating compliance with specific safety directives, ensuring that aircraft meet the required safety standards and are fit for operation. CASA's authority to issue such directives stems from its mandate to regulate civil aviation safety in Australia, ensuring that all aircraft and related activities comply with the highest safety standards.

Scope and Application

The Civil Aviation Regulations 1998, specifically PART 39 - 105, addresses the maintenance and safety requirements for civil aviation, including the issuance of airworthiness directives. This particular directive, AD/PA-23/3, pertains to the Piper PA-23 (Apache and Aztec) series aeroplanes, mandating the replacement of main landing gear forgings and wheels for models with serial numbers (S/Nos.) prior to 23-56. The directive applies to all aeroplanes of the specified model and serial number range, ensuring compliance with safety standards set by the Civil Aviation Safety Authority. It is imperative that the replacement of these components be carried out forthwith, as specified in Piper Service Bulletin No. 128. The directive's scope is confined to the aforementioned aircraft models and serial numbers, and its implementation is governed by the regulations under the Civil Aviation Act 1988, with any further clarification or extension managed through subordinate instruments as necessary.

Key Provisions

The Civil Aviation Regulations 1998, particularly Part 39, provide a comprehensive framework for ensuring the safety and airworthiness of aircraft operating in Australia. Section 39-105(1) pertains specifically to the Piper PA-23 (Apache and Aztec) series aeroplanes and mandates the replacement of main landing gear forgings and wheels. This directive is applicable to all model PA-23 aeroplanes with serial numbers (S/Nos.) prior to 23-56, as specified in the Piper Service Bulletin No. 128. Compliance with this directive is required forthwith, meaning that the replacement must be completed immediately without delay. Under these regulations, the entities responsible for ensuring compliance include aircraft owners, operators, and maintenance personnel. They are obligated to adhere to the directives outlined in the Service Bulletin No. 128 to maintain the airworthiness of the aircraft. This involves inspecting the main landing gear forgings and wheels for any signs of wear, damage, or defects, and replacing them if necessary to meet the safety standards set forth by the Civil Aviation Safety Authority (CASA). The directive leaves no room for ambiguity in terms of urgency and requires prompt action to avoid any potential safety hazards. Failure to comply with these directives can lead to serious consequences. Section 39-105(2) highlights that non-compliance with airworthiness directives can result in enforcement actions. The Civil Aviation Safety Regulations 1998 provide for both civil and criminal penalties for breaches. Civil penalties can include fines, and in severe cases, criminal penalties may apply. The exact financial penalties are not specified in the excerpt but can be substantial, reflecting the critical nature of ensuring aircraft safety. It is imperative that all parties involved take the necessary steps to ensure full compliance to avoid any legal repercussions.
