AD/PA-30/19 - Airflow Modification Kit - Installation

Overview

The Civil Aviation Regulations 1998, enacted by the Australian Parliament, provide the legal framework for ensuring the safety and efficiency of civil aviation in Australia. Part 39 of these Regulations, particularly the 105 Civil Aviation Safety Authority Schedule of Airworthiness Directives, addresses specific safety concerns and operational requirements for various aircraft types. One such directive, AD/PA-30/19, pertains to the Piper PA-30 and 39 (Twin Comanche) series aeroplanes, focusing on the installation of an airflow modification kit. This directive was introduced to address safety issues identified in certain Twin Comanche aircraft models, specifically those with serial numbers prior to 30-2000 that have not been previously modified according to Piper SL No. 558 instructions. The directive aims to ensure these aircraft meet the necessary safety standards before operating, reflecting the overarching policy objective of maintaining high safety standards in civil aviation.

Scope and Application

The Civil Aviation Regulations 1998, specifically under Part 39 - 105, mandate the installation of an Airflow Modification Kit for Piper PA-30 and PA-39 (Twin Comanche) Series Aeroplanes. This directive applies to aircraft with serial numbers prior to 30-2000 that have not been modified according to the instructions detailed in Piper Service Letter No. 558, paragraph 3. This requirement ensures that the aircraft conform to specific airworthiness standards, enhancing flight safety and compliance with national aviation regulations. The regulation is applicable across the Commonwealth of Australia, affecting aircraft owners, operators, and maintenance personnel who must adhere to these standards to legally operate the specified aircraft. The application of this directive is not limited by geographic or jurisdictional boundaries within Australia, thereby ensuring uniform safety standards are maintained nationally. The regulation does not explicitly state exclusions, exemptions, or thresholds, indicating that all applicable aircraft must comply unless otherwise specified through subordinate instruments.

Key Provisions

The main operative sections of this legislation, specifically Civil Aviation Regulations 1998, Part 39 - 105 (1)(2), establish requirements and procedures for the installation of an airflow modification kit on Piper PA-30 and 39 (Twin Comanche) series aeroplanes. The regulation applies to aircraft with serial numbers (S/Nos.) prior to 30-2000 that have not been modified as outlined in Service Letter No. 558, paragraph 3 (1)(3). Compliance with this directive must be achieved before 1 July 1972 (4). Under this legislation, the obligations and requirements imposed on the relevant parties include ensuring that the specified Piper Twin Comanche series aeroplanes are fitted with the airflow modification kit as per the instructions provided in Piper Service Letter No. 558, paragraph 3 (5). This requirement is designed to ensure that the aircraft meet specific safety standards and regulatory compliance, thereby maintaining airworthiness (6). It is imperative that the installation is conducted by authorised personnel and that documentation is kept to verify compliance with these directives (7). Should there be any breaches of these regulations, the legislation outlines potential civil and criminal consequences (8). Although the specific penalties are not detailed within the excerpt, it is common for breaches of civil aviation regulations to result in fines, suspension of aircraft operation licenses, or other regulatory actions that can impact the operational status of the aircraft (9). The severity of penalties may vary depending on the nature and extent of the breach, as well as any harm caused or potential risk posed by non-compliance (10).
