AD/PA-30/22 - Landing Gear and Flap Assemblies - Inspection

Overview

The Civil Aviation Regulations 1998, enacted by the Parliament of Australia, serve to regulate civil aviation safety within the country, addressing the need for stringent and consistent safety standards. One specific aspect of these regulations is the Civil Aviation Safety Authority Schedule of Airworthiness Directives, which includes detailed safety requirements and compliance measures for various aircraft types. This legislative instrument, F2006B05664, pertains to Piper PA-30 and PA-39 series aeroplanes and mandates inspections of the landing gear and flap assemblies to ensure continued airworthiness. The policy objective behind such directives is to mitigate risks associated with mechanical failures by enforcing regular inspections and maintenance, thereby enhancing the safety of air travel. Enacted under the Civil Aviation Act 1988, these regulations were introduced to fill critical gaps in ensuring the safety of civil aviation operations. The specific directive AD/PA-30/22 for Piper PA-30 and PA-39 aeroplanes was designed to address known issues with the landing gear and flap assemblies. Compliance with this directive is required within 100 hours of time in service after 31 December 1973, as outlined in Piper Service Letter No. 650 and its addendum. This legislative measure aims to maintain the highest standards of aviation safety by ensuring that aircraft are regularly inspected and maintained according to stringent criteria set forth by the Civil Aviation Safety Authority.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, under the authority of the Civil Aviation Safety Authority, pertain to the airworthiness directives for Piper PA-30 and 39 (Twin Comanche) Series Aeroplanes. This legislation applies to all models PA-30 and PA-39 with serial numbers within the range 30-1 to 30-2000 and 39-1 to 39-156. The directive mandates that inspections of the landing gear and flap assemblies be conducted within 100 hours of time in service after 31 December 1973. This requirement is supported by Piper Service Letters No. 650 and Addendum 1. The regulations encompass the entire Commonwealth of Australia and are enforced through the Civil Aviation Safety Authority, ensuring compliance across the national jurisdiction. There are no specific exclusions, exemptions, or thresholds outlined within the directive itself, although further clarification or conditions may be established through subordinate instruments or additional civil aviation safety notices issued by the authority.

Key Provisions

The main operative sections of the Civil Aviation Regulations 1998, particularly Part 39 - 105, focus on ensuring the airworthiness of specific aircraft models, including the Piper PA-30 and PA-39 series aeroplanes. Section 39.105 pertains to the specific Airworthiness Directive (AD) for the landing gear and flap assemblies of these models. This directive mandates detailed inspections to be conducted within 100 hours of time in service after 31 December 1973, as outlined in the Piper Service Letter (SL) No. 650 and its Addendum 1. These sections require that the aircraft models PA-30 and PA-39, with serial numbers ranging from 30-1 to 30-2000 and 39-1 to 39-156, undergo thorough inspections to ensure their continued airworthiness. The obligations and requirements imposed by the Act on the parties or entities it governs are stringent and focused on maintaining safety standards. Aircraft operators and owners are mandated to comply with the AD/PA-30/22, ensuring that the landing gear and flap assemblies are inspected within the specified timeframe. This involves a detailed examination of these components as per the Piper SL No. 650 and its Addendum 1, which provides guidance on the inspection process and the criteria for determining airworthiness. Operators must ensure that the inspections are carried out by qualified personnel and that any findings are appropriately addressed before the aircraft can return to service. Failure to comply with the AD/PA-30/22 can result in significant legal and safety repercussions. Under the Civil Aviation Regulations 1998, non-compliance with airworthiness directives is considered an offence. The potential civil and criminal consequences for breaching these provisions can be severe. For instance, operators found to be in breach of the AD may face fines and other penalties as stipulated by the regulations. In serious cases, where the non-compliance leads to safety incidents or accidents, criminal charges could be brought against the responsible parties, with potential maximum penalties including substantial fines and imprisonment. These measures underscore the importance of adhering to the mandated inspection schedules and maintaining the airworthiness of the aircraft.
