AD/PA-28/16 Amdt 2 - Aileron Spar Cracking

Overview

The Civil Aviation Regulations 1998, specifically under Part 39, introduced the Airworthiness Directives to ensure the safe operation of aircraft within Australia. One such directive, AD/PA-28/16 Amendment 2, pertains to Piper PA-28 Series aeroplanes and addresses the issue of aileron spar cracking. This directive was enacted to rectify a safety gap identified in the aileron spar and doubler areas near the hinges of certain models. The Australian Government, through the Civil Aviation Safety Authority, introduced this legislation to enhance the safety standards of aircraft operations by mandating specific inspections to prevent structural failure. The policy objective is to maintain the integrity of the aircraft's control surfaces, thereby ensuring the safety of all passengers and crew. The legislative instrument F2006B05584, issued under the authority of the Civil Aviation Regulations 1998, was created by the Australian Government to address specific safety concerns related to Piper PA-28 Series aeroplanes. The directive targets all models except the PA-28-151 with serial numbers ranging from 28-7415001 to 28-7515459, requiring an inspection of the aileron spar and doubler for any signs of cracking in the radii near the hinges. This requirement must be met at each issue of a new Maintenance Release, ensuring ongoing compliance with safety standards. The directive aims to mitigate the risk of structural failure in these critical components, thereby enhancing the overall safety of air travel within Australia.

Scope and Application

The Civil Aviation Regulations 1998, as amended, pertain to all entities involved in the operation, maintenance, and repair of civil aircraft within Australia. Specifically, AD/PA-28/16 Amendment 2, which addresses aileron spar cracking in Piper PA-28 series aeroplanes, applies to all models of this aircraft series except for PA-28-151 with serial numbers ranging from 28-7415001 to 28-7515459. This directive is mandatory and must be adhered to by aircraft owners, operators, and maintenance personnel to ensure the continued airworthiness of the specified models. The requirement is to inspect the aileron spar and doubler for cracking in the radii around the hinges at each issue of a new Maintenance Release. This regulatory measure is designed to enhance safety by identifying and addressing potential structural failures, thereby ensuring compliance with safety standards set forth by the Civil Aviation Safety Authority. The geographic reach of this regulation is national, applying uniformly across Australia, given that it is a Commonwealth regulation. There are no exclusions or exemptions specified for this directive, meaning all eligible aircraft must comply regardless of their location or the nature of their operations. Subordinate instruments may further extend or clarify the application of this regulation, but the primary requirement remains the inspection and maintenance of the aileron spar as mandated.

Key Provisions

The Civil Aviation Regulations 1998, specifically under PART 39 - 105, mandate certain safety directives for the Piper PA-28 series aeroplanes, with a focus on addressing aileron spar cracking. According to AD/PA-28/16 Amendment 2, the primary requirement is to inspect the aileron spar and doubler for any signs of cracking, particularly in the radii near the hinges (section 1/86). This directive applies to all models of the Piper PA-28 series except for those with serial numbers between 28-7415001 and 28-7515459 (section 1/86). Compliance with this directive must be achieved at each instance a new Maintenance Release is issued. The obligations imposed by this legislation are clear and specific. Aircraft operators and maintenance personnel must ensure that the aileron spar and doubler are inspected meticulously for any signs of cracking, especially in the critical areas around the hinges. This inspection is mandatory at each Maintenance Release, ensuring that the aircraft remains compliant with safety standards set forth by the Civil Aviation Safety Authority. The directive is designed to prevent potential in-flight failures that could arise from undetected structural weaknesses in the aileron spars. Failure to comply with the requirements outlined in AD/PA-28/16 Amendment 2 may lead to serious consequences. Non-compliance can result in safety hazards, and potentially severe civil or criminal penalties. The exact nature and severity of these penalties are detailed in other sections of the Civil Aviation Regulations 1998, but they underscore the importance of adhering to these safety directives. Ensuring adherence to these provisions is critical for maintaining the airworthiness of the aircraft and the safety of all individuals onboard.
