AD/PA-23/38 - Rear Fuselage - Inspection

Overview

The Civil Aviation Regulations 1998, enacted by the Parliament of the Commonwealth of Australia, aim to ensure the safety of civil aviation within Australian airspace. This legislation is essential in regulating various aspects of civil aviation operations, including aircraft maintenance and airworthiness standards. A specific provision within this framework is the Airworthiness Directive (AD) concerning Piper PA-23 (Apache and Aztec) series aeroplanes, which addresses potential safety issues identified in the aircraft's rear fuselage. The AD mandates inspections of the rear fuselage for specified models to ensure structural integrity and compliance with safety standards, thereby mitigating risks associated with identified defects. The objective of this directive is to enhance the safety of civil aviation by ensuring that the aircraft meet necessary safety criteria before resuming flight operations. The AD/PA-23/38, introduced in 1969, is a critical measure within the Civil Aviation Regulations 1998, targeting specific model numbers of Piper PA-23 aeroplanes. This directive was established to address a particular safety concern identified in the rear fuselage of these aircraft, which could potentially compromise structural integrity and flight safety. By requiring inspections within 100 hours of time in service following the directive's issuance on 25 November 1969, the Civil Aviation Safety Authority aims to proactively manage and mitigate safety risks, ensuring that the specified aircraft remain airworthy and compliant with stringent safety regulations. This legislative action underscores the commitment to maintaining high safety standards in civil aviation.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, governs the airworthiness directives concerning the Piper PA-23 (Apache and Aztec) series aeroplanes. This legislative instrument applies to the specific models of PA-23-250 aeroplanes identified by their serial numbers, which are detailed within the schedule of airworthiness directives. The regulations mandate that compliance with the inspection requirements outlined in AD/PA-23/38 must be achieved within 100 hours of time in service after 25 November 1969, as stipulated in Piper Service Bulletin No. 296. The scope of this legislation is strictly confined to ensuring the specified aircraft meet the required safety standards, and it does not extend to other aircraft models or types unless explicitly stated in other airworthiness directives or regulations. The application of these directives is overseen by the Civil Aviation Safety Authority, ensuring that the safety standards are uniformly enforced across the Commonwealth of Australia.

Key Provisions

The Civil Aviation Regulations 1998, specifically Part 39 - 105, mandates Airworthiness Directives (ADs) that ensure the safety of aircraft operations in Australia. Section 39.105 outlines the requirement for compliance with ADs, which are issued to address safety issues identified in certain aircraft models. For the Piper PA-23 series aeroplanes, AD/PA-23/38 pertains to the rear fuselage inspection of specific models and serial numbers, as detailed in the document Piper SB No. 296. The directive requires these aircraft to undergo an inspection within 100 hours of time in service after 25 November 1969 to ensure that any potential structural issues are identified and addressed. The obligations under AD/PA-23/38 are clear and specific. Owners or operators of the affected Piper PA-23-250 aircraft must ensure that the rear fuselage inspection is conducted by an authorised individual, such as a licensed aircraft maintenance engineer. This inspection must be meticulously performed to detect any signs of structural damage, corrosion, or wear that could compromise the integrity of the aircraft. The requirement is not only to perform the inspection but also to document the findings and any corrective actions taken, ensuring that all records are kept up to date and available for review by the Civil Aviation Safety Authority (CASA) upon request. Failure to comply with AD/PA-23/38 can result in severe consequences. Section 9.05 of the Civil Aviation Act 1988 imposes penalties for non-compliance with ADs, which may include fines and potential criminal charges. The specific penalties can vary based on the severity and frequency of the breach, but they may include substantial fines for individuals and corporations. In cases where non-compliance leads to an accident or incident, the penalties can be more severe, with potential criminal charges carrying significant fines and imprisonment terms. Therefore, adherence to the AD is not only a regulatory requirement but also a critical safety measure to protect both the aircraft's occupants and the general public.
