AD/PA-23/19 - Elevator Control Tube Bellcrank Attachment - Modification

Overview

The Civil Aviation Regulations 1998, as amended, address the need for stringent safety measures in the operation of civil aircraft within Australia. This legislative instrument was enacted to ensure that aircraft are maintained to a high standard of airworthiness and safety, preventing accidents and incidents that may arise from mechanical failures or design deficiencies. Part 39 of the Civil Aviation Regulations 1998 provides specific requirements and directives for ensuring the airworthiness of aircraft, including the issuance of Airworthiness Directives (ADs) for specific aircraft models. The policy objective of these regulations is to ensure the safety of the public and aviation personnel by mandating regular inspections and maintenance checks on aircraft, thereby reducing the risk of in-flight failures and accidents. One example of such an airworthiness directive is AD/PA-23/19, which pertains to the Piper PA-23 (Apache and Aztec) series aeroplanes. This directive addresses a specific issue with the elevator control tube bellcrank attachment and requires compliance at intervals not exceeding 100 hours of time in service after 30 May 1960. This regulation was introduced by the Civil Aviation Safety Authority to mitigate potential risks associated with the identified issue, ensuring that the aircraft maintain their airworthiness and safety standards. The regulations are enforced by the Commonwealth of Australia, with the Civil Aviation Safety Authority being the relevant authority responsible for the implementation and oversight of these safety measures.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, addresses the Airworthiness Directives (AD) for aircraft, including the Piper PA-23 (Apache and Aztec) Series Aeroplanes. AD/PA-23/19 pertains to modifications required to the elevator control tube bellcrank attachment for certain models of these aircraft. The directive applies to Piper PA-23 and PA-23-160 models with serial numbers ranging from 23-1 to 23-1691, necessitating compliance with the guidelines set forth in Piper Service Bulletin No. 176. The requirement is to undertake these modifications at intervals not exceeding 100 hours of time in service after 30 May 1960. This directive is a crucial component in ensuring the continued airworthiness and safety of the specified aircraft, thereby affecting the operations of owners, operators, and maintenance personnel of these aircraft within Australia and its territories. The Civil Aviation Safety Authority oversees the compliance and enforcement of this directive, ensuring that all relevant entities adhere to the specified safety standards.

Key Provisions

The Civil Aviation Regulations 1998, specifically in Part 39 - 105, include a detailed schedule of airworthiness directives (ADs) that pertain to various aircraft models. One such directive, AD/PA-23/19, applies to Piper PA-23 (Apache and Aztec) series aeroplanes. This directive mandates modifications to the elevator control tube bellcrank attachment (Section 5/60). According to the applicability criteria outlined, this directive applies to models PA-23 and PA-23-160 with serial numbers ranging from 23-1 to 23-1691. Compliance with this directive is essential and is referenced in Piper Service Bulletin No. 176. Under the Civil Aviation Regulations 1998, compliance with AD/PA-23/19 requires that the specified modifications to the elevator control tube bellcrank attachment be performed at intervals not exceeding 100 hours of time in service after the directive’s effective date of 30 May 1960. These modifications are crucial for maintaining the airworthiness of the aircraft and ensuring safety standards are upheld. The regulations place the onus on aircraft operators and maintenance personnel to ensure these modifications are completed within the specified timeframes. Failure to adhere to the requirements set forth in AD/PA-23/19 can result in severe consequences. The Civil Aviation Regulations 1998 impose penalties for non-compliance with ADs, which can include substantial fines and potential criminal charges. The exact penalties are not detailed in the provided excerpt but typically can extend to significant financial penalties and imprisonment. Ensuring compliance is not just a regulatory requirement but also a matter of safety and legal obligation to avoid these adverse outcomes. In summary, AD/PA-23/19 under the Civil Aviation Regulations 1998 mandates specific modifications to the elevator control tube bellcrank attachment of Piper PA-23 series aeroplanes within a 100-hour service interval after 30 May 1960. Compliance is mandatory, with stringent penalties for non-compliance, including fines and possible imprisonment. These provisions underscore the importance of adhering to airworthiness directives to maintain safety and regulatory standards in aviation.
