Requirement: Clamp the turbocharger oil supply hose in accordance with the instructions, Piper SB 815.
Compliance: Within 10 hours time in service after 31st January 1986.
Background: Due to loosening or breakage of the ties securing the turbocharger oil supply hose to the turbo charger support bracket the hose is being burnt. If this condition is not rectified the hose may fail resulting in an inflight fire, oil loss and/or engine failure.
Overview
The Civil Aviation Regulations 1998, enacted by the Parliament of Australia, are designed to ensure the safety of civil aviation within Australian airspace. A particular regulation within this legislative framework, F2006B07499, pertains to the Aerostar (Piper/Ted Smith) 600 and 700 Series Aeroplanes, addressing a critical safety issue related to the turbocharger oil supply hose. The regulation was introduced to rectify a problem where the turbocharger oil supply hose could loosen or break, leading to potential in-flight fires, oil loss, and engine failure. The policy objective behind this regulation is to mandate compliance with specific instructions to secure the turbocharger oil supply hose, as outlined in Piper Service Bulletin No 815, to mitigate these risks and ensure the safe operation of the affected aircraft. Compliance with this regulation is required within 10 hours of time in service after 31 January 1986.
Scope and Application
The Civil Aviation Regulations 1998, specifically Part 39 - 105, issued by the Civil Aviation Safety Authority, mandates specific safety directives for certain types of aircraft. This particular directive, AD/TSA-600/35, applies to all Aerostar 600 and 700 Series aeroplanes equipped with automatic waste gate controllers and a specific turbo oil supply hose replacement kit, as identified by Piper Part No. 764-951V and installed as per Piper Service Bulletin No. 761. The affected aircraft models include the PA-60-601 Aerostar 601 with certain serial number ranges, the PA-60-601P Aerostar 601P, the PA-60-602P Aerostar 602P, and the PA-60-700P Aerostar 700P within specific serial number ranges. The directive requires these aircraft to clamp the turbocharger oil supply hose according to Piper Service Bulletin No. 815 to prevent potential in-flight hazards such as hose burning, in-flight fires, oil loss, and engine failure. Compliance with this directive must be achieved within 10 hours of time in service after 31st January 1986. The regulation’s scope is explicitly defined to ensure that only the specified aircraft models and configurations are subject to these safety requirements.
Key Provisions
The Civil Aviation Regulations 1998, specifically under Part 39, 105, outlines the Civil Aviation Safety Authority's schedule of airworthiness directives, including AD/TSA-600/35 concerning the Aerostar (Piper/Ted Smith) 600 and 700 series aeroplanes. This directive focuses on securing the turbocharger oil supply hose (section 3/86). The applicability of this directive is for all Aerostar aircraft equipped with automatic waste gate controllers and a turbo oil supply hose replacement kit, Piper Part NO 764-951V, installed as per Piper Service Bulletin No 761. The affected aircraft include specific serial numbers of the PA-60-601, PA-60-601P, PA-60-602P, and PA-60-700P models.
The main requirement of AD/TSA-600/35 is to clamp the turbocharger oil supply hose in accordance with the instructions provided in Piper Service Bulletin No 815. This action is essential to prevent issues such as the hose becoming loose or breaking, which could result in severe consequences including an inflight fire, oil loss, and engine failure. Compliance with this directive must be achieved within 10 hours of time in service after 31 January 1986.
Entities governed by this regulation, primarily aircraft owners and operators, are required to ensure that the specified modifications and checks are performed on the affected aircraft. This involves following the detailed instructions provided in Piper Service Bulletin No 815 to secure the turbocharger oil supply hose properly. It is critical that these steps are completed within the specified timeframe to maintain the airworthiness of the aircraft and ensure safety during operation.
Failure to comply with the requirements of AD/TSA-600/35 may result in serious legal and safety consequences. While the Civil Aviation Regulations do not explicitly state the penalties for non-compliance in this instance, breaches of airworthiness directives can lead to significant civil or criminal liabilities. Potential consequences may include fines, penalties, and legal actions against the aircraft owner or operator. Additionally, the aircraft may be grounded until the required modifications are made, impacting the operational readiness and potentially leading to further financial losses. It is therefore imperative for all parties involved to adhere strictly to the provisions of this directive.
