Compliance: | 1. | Unless previously accomplished; within 10 hours aircraft time in service and thereafter at intervals not to exceed 55 hours aircraft time in service. |
| 2. | Unless previously accomplished; within 10 hours aircraft time in service and thereafter at intervals not to exceed 110 hours aircraft time in service or 6 months, whichever occurs first. |
| 3. | Following every disassembly of an Aerostar exhaust system. |
This Amendment becomes effective on 20 March 2003.
Background: This Directive was originally issued to address reports of Aerostar exhaust systems failing in service. Exhaust system defects can result in an engine fire. This Amendment is issued in response to a review of an Airworthiness Directive application. The application requested a 10% tolerance to the exhaust system inspection intervals.

Delegate of the Civil Aviation Safety Authority 3 February 2003
The above AD is notified in the Commonwealth of Australia Gazette on 26 February 2003.
Overview
The Civil Aviation Safety Authority Act 1998 (CASA Act) was enacted in 1998 and is administered by the Civil Aviation Safety Authority (CASA), an agency of the Australian Government responsible for regulating civil aviation safety. The CASA Act aims to provide a framework for the regulation of civil aviation safety in Australia, ensuring that air services are provided in a safe and efficient manner. The Act allows CASA to issue airworthiness directives to address identified safety issues with aircraft and aeronautical products. One such airworthiness directive, AD/TSA-600/36 Amdt 3, was issued in 2003 to address the issue of engine exhaust system failures in Aerostar (Piper/Ted Smith) 600 and 700 Series Aeroplanes. The policy objective of this directive is to ensure the continued airworthiness of affected aircraft by mandating regular inspections and repairs of the engine exhaust system.
Scope and Application
The Airworthiness Directive (AD) AD/TSA-600/36 Amdt 3 applies to Aerostar (Piper/Ted Smith) 600 and 700 Series aeroplanes, specifically the Piper and Ted Smith Aerostar Models 600, 601, 601P, 602P, and 700P. This legislation mandates specific safety requirements for the engine exhaust systems of these aircraft models to address safety concerns and mitigate risks associated with exhaust system failures, which can lead to engine fires. The AD applies to all aircraft within the specified models and is issued under the authority of the Civil Aviation Safety Authority (CASA) delegate, James Coyne. The directive revokes the previous Amendment 2 and is effective from 20 March 2003, as notified in the Commonwealth of Australia Gazette on 26 February 2003. The requirements set out in the AD must be adhered to by the operators of the affected aircraft, ensuring that inspections and maintenance actions are performed within the specified timeframes to maintain airworthiness standards.
Key Provisions
This legislative instrument outlines an Airworthiness Directive (AD) issued by the Civil Aviation Safety Authority (CASA), specifically targeting Aerostar (Piper/Ted Smith) 600 and 700 series aeroplanes. Section 1 of the AD (referred to as AD/TSA-600/36 Amdt 3) mandates that specific actions must be taken regarding the engine exhaust systems of these aircraft to address the unsafe condition of potential failure that could lead to an engine fire. The directive applies to Piper and Ted Smith Aerostar Models 600, 601, 601P, 602P, and 700P. Section 2 of the directive specifies the requirements, which vary slightly depending on the model of the aeroplane. For the 600 models, the requirement is to inspect the engine exhaust system according to Piper Aircraft's Maintenance Manual. Models 601, 601P, 602P, and 700P require the removal and inspection of the engine exhaust system, following a specific Piper Service Bulletin. All models must have their engine exhaust system installed according to Piper's Maintenance Manual.
Section 3 of the AD lays out the compliance timeline, which requires actions to be taken within specific intervals post the aeroplane's service hours. For 600 models, inspections must be performed within 10 hours of aircraft time in service and thereafter at intervals not exceeding 55 hours. For 601, 601P, 602P, and 700P models, the initial action must be taken within 10 hours of aircraft time in service and thereafter at intervals not exceeding 110 hours or six months, whichever is sooner. Additionally, the engine exhaust system must be installed following every disassembly of an Aerostar exhaust system.
The AD imposes obligations on the aircraft operators to ensure that these inspections and installations are carried out in accordance with the specified manuals and bulletins. Failure to comply with these requirements can result in significant safety risks, including the potential for engine fires. The AD is a legal mandate, and non-compliance could lead to civil or criminal consequences as stipulated by the Civil Aviation Regulations (CAR) 1998. While specific penalties are not detailed in the AD, non-compliance with CASA directives can result in substantial fines and possible suspension or revocation of the aircraft's certificate of airworthiness. Therefore, it is crucial for operators to adhere strictly to the AD's requirements to maintain the safety and airworthiness of their aircraft.
