Airworthiness Directive · Amendment 39-15149 · Teledyne Continental Motors Reciprocating (TCM) Engine Models IO-550-N, TSIO-520-BE, TSIO-550-A, TSIO-550-B, TSIO-550-C, TSIO-550-E, and TSIO-550-G
Teledyne Continental Motors Reciprocating (TCM) Engine Models IO-550-N, TSIO-520-BE, TSIO-550-A, TSIO-550-B, TSIO-550-C, TSIO-550-E, and TSIO-550-G
This AD applies to:
(1) Teledyne Continental Motors (TCM) models TSIO-520-BE, TSIO-550-A, TSIO-550-B, TSIO-550-C, TSIO-550-E, and TSIO-550-G reciprocating engines with a Kelly Aerospace Power Systems turbocharger, TCM part number (P/N) 646677, with certain serial numbers (SNs), installed on or after March 20, 2007. These engines are installed on, but not limited to, Adam Aircraft A500, Columbia Aircraft Manufacturing LC41-550FG, Mooney Airplane Company M20TN (Acclaim), and Piper Aircraft Incorporated PA-46-310P (Malibu) airplanes.
(2) TCM IO-550-N reciprocating engines modified to Engine Technologies Incorporated supplemental type certificate (STC) SE10589SC to install turbocharger, P/N 466304-0003, with certain SNs, installed on or after March 20, 2007. These engines are installed on, but not limited to, Cirrus Design Corporation Aircraft Model SR22 modified to Engine Technologies Incorporated STC SA10588SC.
The FAA is adopting a new airworthiness directive (AD) for TCM IO-550-N, TSIO-520-BE, TSIO-550-A, TSIO-550-B, TSIO-550-C, TSIO-550-E, and TSIO-550-G reciprocating engines. This AD requires removing before further flight, certain Kelly Aerospace Power Systems turbochargers, part number (P/N) 466304-0003, listed by serial number in this AD. This AD results from four incidents of the turbine rotor separating from the shaft of the turbocharger. We are issuing this AD to prevent the turbine rotor from separating from the shaft of the turbocharger due to a machining defect in the turbocharger compressor. This condition could result in full engine power loss, loss of engine lubricant, or smoke in the airplane cabin.
You are responsible for having the actions required by this AD performed before further flight unless the actions have already been done.
(f) If your engine has a turbocharger that was installed before March 20, 2007, no further action is required.
Before further flight, for engines modified to Engine Technologies Incorporated STC SE10589SC on or after March 20, 2007, with a turbocharger that has a SN listed in Kelly Aerospace Service Bulletin (SB) No. 026, Revision B, dated July 27, 2007, replace the turbocharger.
Before further flight, for engines with a Kelly Aerospace Power Systems turbocharger, TCM P/N 646677 installed on or after March 20, 2007, with a turbocharger SN listed in Kelly Aerospace SB No. 027, dated July 25, 2007, replace the turbocharger.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
