AD/PA-24/31 - Landing Gear and Flap Assemblies - Inspection

Overview

The Civil Aviation Regulations 1998, amended through the legislative instrument F2006B05530, was enacted to ensure the safety and compliance of civil aviation operations in Australia. This specific amendment, which pertains to PART 39 - 105, focuses on establishing the Schedule of Airworthiness Directives for Piper PA-24 (Comanche) series aeroplanes. It was introduced to address the need for specific inspections on landing gear and flap assemblies to mitigate potential safety risks associated with these aircraft models. The enactment of these regulations by the Commonwealth of Australia was aimed at providing clear, enforceable directives to maintain the airworthiness of these specific aircraft models, thereby enhancing overall aviation safety. The policy objective of this regulation, as outlined in the legislative instrument, is to ensure that Piper PA-24 (Comanche) series aeroplanes are maintained in a safe and airworthy condition by mandating regular inspections of the landing gear and flap assemblies. This is achieved through the issuance of specific Airworthiness Directives, which require compliance within 100 hours of time in service after 31 December 1973, for the applicable models and serial numbers. The directive references Piper Service Letter No. 650, Addendum 1, as the document that outlines the necessary inspection procedures.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, mandates the application of the Civil Aviation Safety Authority’s (CASA) Airworthiness Directives for Piper PA-24 (Comanche) series aeroplanes, focusing on the inspection of landing gear and flap assemblies. This legislation applies to the specific models PA-24-180, PA-24-250, PA-24-260, and PA-24-400 with serial numbers ranging from 24-1 to 24-5047 and 26-2 to 26-148. Compliance is required within 100 hours of time in service following 31 December 1973. This directive, identified as AD/PA-24/31, is to be adhered to by the aircraft operators, maintenance providers, and other relevant entities involved in the operation and upkeep of these aircraft. The directive's reach is confined to the Commonwealth of Australia, overseen by CASA. The scope of this directive is limited to the inspection requirements detailed in Piper Service Letter No. 650, Addendum 1, and does not extend to other areas of aircraft maintenance unless specified in subordinate instruments.

Key Provisions

The main operative sections of the Civil Aviation Regulations 1998, specifically PART 39 - 105 AD/PA-24/31, pertain to the inspection requirements for Piper PA-24 (Comanche) Series Aeroplanes, particularly focusing on the landing gear and flap assemblies. These sections (12/73) mandate that models PA-24-180, PA-24-250, PA-24-260, and PA-24-400 with specific serial numbers must comply with the inspection directives outlined in the Piper Service Letter No. 650, Addendum 1. The compliance timeframe requires these inspections to be completed within 100 hours of the aircraft being in service after 31 December 1973. The obligations imposed by these regulations on the parties involved, particularly aircraft operators and maintenance personnel, are quite specific. They must ensure that the inspections of the landing gear and flap assemblies are conducted according to the detailed guidelines provided in the referenced service letter. This involves thorough examination and documentation to verify the airworthiness of these critical components, ensuring they meet the required safety standards set forth by the Civil Aviation Safety Authority (CASA). Failure to comply with these provisions can result in serious consequences. The Civil Aviation Regulations include various offences and penalties for non-compliance. For instance, non-compliance with airworthiness directives can result in civil penalties under Section 88 of the Civil Aviation Act 1988, which may include fines up to a significant amount determined by the court. Additionally, there could be criminal penalties if the non-compliance is deemed to have endangered safety, leading to prosecution under Section 91 of the Act, potentially resulting in imprisonment. The potential penalties underscore the importance of adhering to these regulations. Operators and maintenance personnel must ensure that all inspections are performed diligently and accurately. Any deviation from the prescribed requirements not only risks significant financial penalties but also poses a serious threat to the safety of the aircraft and its occupants. Thus, compliance is not just a legal requirement but a fundamental aspect of maintaining aviation safety standards.
