The AD requires that the action set out in the requirement section (being action that the delegate considers necessary to correct the unsafe condition) be taken in relation to the aircraft or aeronautical product mentioned in the applicability section: (a) in the circumstances mentioned in the requirement section; and (b) in accordance with the instructions set out in the requirement section; and (c) at the time mentioned in the compliance section.

Aerostar (Piper/Ted Smith) 600 and 700 Series Aeroplanes
AD/TSA-600/36  Engine Exhaust Systems and installation of Fire Detection System for Turbocharged Aircraft  11/2012
Amdt 4

Applicability:  Piper Models PA-60-600, PA-60-601, PA-60-601P, PA-60-602P, and PA-60-700P (all serial numbers (S/N)) airplanes, and Ted Smith Aerostar (Butler Aircraft Company) Models 600, 601, 601A, 601B, and 601P (all S/N) airplanes, certificated in any category, except those airplanes incorporating Machen Supplemental Type Certificate (STC) SA980NM.
Requirement:       1. All turbocharged models:

                  Modify the airplane by installing Piper Engine Fire Detection System Kit, Piper Part Number 764-158, in accordance with the instructions in Part II of the Aerostar Aircraft Corporation (SB) No. 920A, dated September 12, 1991, and modify the Airplane Flight Manual/Pilot's Operating Handbook by inserting the appropriate supplement provided with the above kit.

                   2. All models:

                    Remove and inspect the engine exhaust system in accordance with Aerostar Aircraft Corporation Service Bulletin Number 920A Part 1 and in accordance with Piper Aircraft 600/601/601P/602P/700P Maintenance Manual Chapter
                   5-20-01 page 5-10.  Install the engine exhaust system in accordance with Piper Aircraft 600/601/601P/602P/700P Maintenance Manual Chapter 78-11-05 page 78-05.
Compliance:         1. Unless previously accomplished; within 6 months of the effective date of this Directive.

                    2. Unless previously accomplished; within 10 hours aircraft time in service and thereafter at intervals not to exceed 50 (+5 tolerance)* hours aircraft time in service or 6 months, whichever occurs first.

                Note 1:  Accomplishment of Part III of SB 920A for Turbocharged models (installation of Bolted Flange Inconel Tailpipe kit in accordance with STC
                SA 4976NM) will relieve the repetitive 50 hour dismantling inspection requirement of Part 1 of SB 920A and the requirement 2 of this AD.  The 50 hour repetitive inspection will still be required for the non-turbocharged models.

                This Amendment becomes effective on 4 June 2012.
Background:     Note 2:  An extension to the interval for Requirement 2 of this AD (use of 5 hour tolerance) must not extend the subsequent occurrence of Requirement 2.  For example, if as a result of an extension to Requirement 2 (having an
