AD/PA-46/13 - Flap Actuator Tube

Overview

The Civil Aviation Regulations 1998, specifically within Part 39, include a directive addressing the airworthiness of Piper PA-46 (Malibu) series aeroplanes. Enacted by the Commonwealth of Australia, this legislation aims to ensure that specific models of these aeroplanes meet essential safety standards. This is evident in the Airworthiness Directive AD/PA-46/13, which targets a critical issue identified in certain PA-46-310P models concerning the flap actuator tube. The directive mandates compliance with Piper Service Bulletin No 862 to rectify a potential failure due to insufficient weld penetration after machining. The objective is to maintain and enhance aviation safety by requiring action within 100 hours of time in service after 31 July 1987 or at the next scheduled inspection for Maintenance Release, whichever is later. This legislative instrument is part of a broader regulatory framework overseen by the Civil Aviation Safety Authority, reinforcing the commitment to ensuring that all civil aviation activities within Australia adhere to stringent safety standards. The directive is a proactive measure to address identified risks and maintain the integrity of aircraft operations.

Scope and Application

The Civil Aviation Regulations 1998, specifically under PART 39 - 105, pertains to the application of Airworthiness Directives (AD) for various aircraft types, including the Piper PA-46 (Malibu) series aeroplanes. This regulation applies to all model PA-46-310P aeroplanes with serial numbers ranging from 46-8608001 to 46-8608067 and 4608001 to 4608064. The AD requires compliance with Piper Service Bulletin No 862 to address the reported failure of a flap actuator tube, which was found to be due to insufficient weld penetration following machining. Compliance with this directive must be achieved within 100 hours of the aeroplane's time in service after 31 July 1987 or at the next scheduled inspection for maintenance release after that date, whichever is later. This regulation enforces specific safety measures on designated aeroplanes to ensure continued airworthiness and safety in Australian airspace.

Key Provisions

The Civil Aviation Regulations 1998, specifically under Part 39 - 105, includes Airworthiness Directives that govern the maintenance and operation of certain aircraft. For Piper PA-46 Malibu series aeroplanes, Airworthiness Directive (AD) PA-46/13 (section 39-105) pertains to the flap actuator tube of specific model numbers. This directive applies to all model PA-46-310P with serial numbers (S/Nos) 46-8608001 to 46-8608067 and 4608001 to 4608064. The requirement outlined in this directive mandates that action must be taken in accordance with Piper Service Bulletin (SB) No 862. This action must be completed within 100 hours of time in service after 31 July 1987, or at the next scheduled inspection for Maintenance Release issue after 31 July 1987, whichever is later. This Airworthiness Directive imposes specific obligations on aircraft operators and maintenance personnel. It is essential that the action required by Piper SB No 862 be performed within the specified timeframe to ensure compliance with safety regulations. Failure to comply with this directive can result in serious safety risks, as the directive addresses a reported failure of a flap actuator tube attributed to insufficient weld penetration after machining. The directive aims to prevent potential structural failures that could compromise the aircraft's safety during flight. Breaching the requirements set out in AD PA-46/13 can lead to severe consequences. The Civil Aviation Safety Authority (CASA) has the authority to enforce compliance and may impose penalties for non-compliance. While the specific penalties are not detailed in the text, it is understood that violations of Airworthiness Directives can result in significant fines, enforcement actions, or even grounding of the aircraft until compliance is achieved. The potential for such consequences underscores the importance of adhering to the directive's requirements to maintain airworthiness standards and ensure the safety of all passengers and crew. The directive also highlights the need for thorough record-keeping and regular inspections to ensure that the specified maintenance actions are completed within the required timeframe. Operators and maintenance personnel must be diligent in monitoring the aircraft's service hours and scheduled inspections to ensure timely compliance with AD PA-46/13. This proactive approach not only helps in avoiding potential safety issues but also ensures that the aircraft remains in a compliant and airworthy condition, thereby fostering a culture of safety and reliability in aviation operations.
