AD/PA-23/5 - Main Landing Gear Attachment Points - Modification

Overview

The Civil Aviation Regulations 1998, enacted by the Parliament of the Commonwealth of Australia, form a comprehensive framework governing civil aviation safety and operations within Australia. Among these regulations, Part 39 specifically addresses airworthiness directives, which are critical in ensuring that aircraft maintain the necessary standards for safe operation. The 1998 Regulations were introduced to provide a cohesive and legally binding set of rules to address safety concerns and operational standards in civil aviation, thereby protecting the public and ensuring the integrity of the aviation industry. Within this framework, AD/PA-23/5 is an airworthiness directive that targets the Piper PA-23 (Apache and Aztec) Series Aeroplanes, specifically addressing modifications to the main landing gear attachment. This directive applies to aircraft with serial numbers 23-1 to 23-109 and mandates compliance with Piper Service Bulletin No. 134. The directive aims to rectify safety issues by requiring immediate action to ensure that the aircraft meet the required airworthiness standards, thereby enhancing overall aviation safety.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, under the Civil Aviation Safety Authority, applies to the Piper PA-23 series aeroplanes, more precisely those with serial numbers (S/Nos.) ranging from 23-1 to 23-109. This legislation mandates modifications to the main landing gear attachment points of the affected aircraft to ensure compliance with the standards set by the authority. The requirement is to be fulfilled immediately, as stipulated in the Piper Service Bulletin No. 134. The regulation extends across the Commonwealth of Australia, enforcing compliance nationwide. There are no specific exclusions or exemptions detailed in the document, and compliance must be achieved without delay to maintain airworthiness standards. Subordinate instruments or additional clarifications may be issued to elaborate on the compliance process or address any arising issues.

Key Provisions

The Civil Aviation Regulations 1998, under PART 39 - 105, outlines specific airworthiness directives for certain aircraft models, including the Piper PA-23 (Apache and Aztec) series aeroplanes. One such directive, AD/PA-23/5, focuses on the modification of the main landing gear attachment NK points for these aircraft. The directive applies to aircraft with serial numbers ranging from 23-1 to 23-109, and it mandates compliance without delay as indicated by the "Forthwith" requirement. The directive refers to Piper Service Bulletin No. 134 for detailed instructions on the necessary modifications. The main obligation imposed by this directive is for the aircraft operators or owners to ensure that the specified modifications to the main landing gear attachment NK points are carried out promptly. This requirement is crucial to maintain the airworthiness of the aircraft and to comply with safety standards set by the Civil Aviation Safety Authority (CASA). The directive leaves no room for delay in implementing these modifications, emphasising the urgency and importance of adherence to the specified procedures. Failure to comply with the airworthiness directive AD/PA-23/5 can result in serious consequences. According to the regulations, non-compliance can lead to potential safety hazards that may compromise the integrity of the aircraft during flight. While the specific penalties for breach of these directives are not detailed in the referenced text, non-compliance generally can result in enforcement actions by CASA, including fines, suspension of airworthiness certificates, and other regulatory penalties. The severity of the penalties may depend on the extent of non-compliance and the risk posed to aviation safety.
