AD/PA-31/19 - Flap Track and Rudder Tip Rib Assemblies - Inspection

Overview

The Civil Aviation Regulations 1998, amended by the legislative instrument F2006B05724, address safety concerns in civil aviation by specifying requirements for maintaining aircraft airworthiness. Enacted by the Commonwealth of Australia, these regulations are overseen by the Civil Aviation Safety Authority (CASA), aiming to ensure that aircraft operations meet safety standards. The specific Airworthiness Directive AD/PA-31/19 targets Piper PA-31 series aeroplanes, focusing on the inspection of flap track and rudder tip rib assemblies to prevent potential structural failures that could compromise flight safety. This directive applies to aircraft models PA-31 and PA-31-300 with specific serial numbers, mandating inspections within 100 hours of time in service after 31 December 1971, thereby enhancing overall aviation safety and compliance with regulatory standards.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, pertains to the safety directives issued by the Civil Aviation Safety Authority, focusing on maintaining the airworthiness of aircraft within Australia's jurisdiction. This legislation applies to the Piper PA-31 Series aeroplanes, encompassing model PA-31 with serial numbers prior to 31-172 for Part 1, and models PA-31 and PA-31-300 with serial numbers prior to 31-460 for Part 2, as outlined in Schedule of Airworthiness Directives AD/PA-31/19. The directive mandates a thorough inspection of the flap track and rudder tip rib assemblies within 100 hours of time in service following 31 December 1971, ensuring compliance with safety standards and mitigating potential risks associated with these components. The regulations extend throughout the Commonwealth, enforcing these safety measures across all states and territories to maintain uniform standards of aviation safety. The applicability of these regulations is confined to the specified Piper PA-31 Series aeroplanes, ensuring that only those aircraft meeting the outlined criteria are subject to the inspection requirements. The Civil Aviation Safety Authority enforces these standards to maintain the highest levels of safety within the Australian aviation industry. The scope of the Act does not include any explicit exclusions or exemptions, meaning that all affected aircraft must comply with the inspection mandates. Any further detailing or extensions of the application are addressed through subordinate instruments, which may provide additional specifications or clarifications as necessary.

Key Provisions

The Civil Aviation Regulations 1998, specifically Part 39 - 105, contain detailed provisions related to airworthiness directives for certain aircraft models. One such directive, AD/PA-31/19, pertains to the inspection of flap track and rudder tip rib assemblies for Piper PA-31 series aeroplanes. According to section 12/71, this directive applies to Part 1 of SL No. 594, which covers Model PA-31 aeroplanes with serial numbers prior to 31-172, and Part 2 of SL No. 594, which covers Models PA-31 and PA-31-300 with serial numbers prior to 31-460. The directive mandates that compliance must be achieved within 100 hours of time in service after 31 December 1971. Essentially, this means that the specified aircraft must undergo a thorough inspection of the flap track and rudder tip rib assemblies to ensure they meet the required safety standards. This requirement ensures that the critical structural components of these aeroplanes are regularly checked and maintained, reducing the risk of in-flight failures. Entities governed by these regulations, including aircraft manufacturers, operators, and maintenance providers, have specific obligations under this directive. They must ensure that the specified aeroplanes are inspected according to the timelines outlined in the directive. This involves scheduling and performing the required inspections, documenting the findings, and ensuring any necessary repairs or modifications are carried out to maintain the airworthiness of the aircraft. Failure to comply with these airworthiness directives can lead to severe consequences. The Civil Aviation Regulations impose both civil and criminal penalties for non-compliance. Civil penalties may include fines, while criminal penalties could involve imprisonment, depending on the severity of the breach. The exact penalties are detailed in the broader Civil Aviation Act 1988, which provides a framework for enforcing compliance with airworthiness directives. It is crucial for all parties involved to adhere strictly to these requirements to avoid facing legal repercussions.
