Airworthiness Directive 2007-16-10
one-timeAirworthiness Directives; 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
What this AD requires
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.
Which aircraft AD 2007-16-10 applies to
Applies only to engines with a Kelly Aerospace Power Systems turbocharger installed on or after March 20, 2007, with certain serial numbers: P/N 646677 for the TSIO-520-BE/TSIO-550 group, or P/N 466304-0003 for TCM IO-550-N engines modified to Engine Technologies Incorporated STC SE10589SC (Cirrus SR22 modified to STC SA10588SC).
Whether AD 2007-16-10 actually applies to your aircraft (by serial and installed parts) and whether it’s already complied with comes from that aircraft’s records.
How AD compliance is recorded
A valid compliance record (14 CFR 43.9) states:
Tailplate reads a tail number’s logbooks and matches every applicable AD — including this one — to its compliance evidence, with recurring next-due dates computed.
