Airworthiness Directives; Teledyne Continental Motors (TCM) IO-520, TSIO-520, and IO-550 Series Reciprocating Engines With Superior Air Parts, Inc. (SAP) Cylinder Assemblies Installed

The FAA is adopting a new airworthiness directive (AD) for certain TCM IO-520, TSIO-520, and IO-550 series reciprocating engines, with certain SAP investment cast cylinder assemblies installed. This AD requires initial and repetitive inspections and compression tests to detect cracks in those cylinders with more than 750 flight hours (FH) time-in-service (TIS). This AD results from reports of cracks in the area of the exhaust valve and separation of cylinder heads from the barrels of SAP cylinder assemblies with certain part numbers. We are issuing this AD to prevent the separation of the cylinder head, which could result in immediate loss of engine power, possible structural damage to the engine, and possible fire in the engine compartment.

Full official abstract

Airworthiness Directives; Continental Motors, Inc. (CMI) Reciprocating Engines

We are superseding an existing airworthiness directive (AD) for certain Continental Motors, Inc. (CMI) models TSIO-520, TSIO-550-K, TSIOF-550K, and IO-550-N series reciprocating engines with new or rebuilt CMI starter adapters installed between January 1, 2011 and November 20, 2011. That AD currently requires replacing affected CMI starter adapters with starter adapters eligible for installation. This AD requires the same actions, but to an expanded population of reciprocating engines. This AD was prompted by two additional reports received of fractures in starter adapter gear shafts in certain additional part number (P/N) CMI starter adapters since we issued the existing AD. We are issuing this AD to prevent starter adapter gear shaft failure which could cause oil scavenge pump failure and engine in-flight shutdown.

Airworthiness Directives; Teledyne Continental Motors O-470, IO-470, TSIO-470, IO-520, TSIO-520, IO-550, and IOF-550 Series Reciprocating Engines; Correction

The FAA is correcting airworthiness directive (AD) 2009-19-06, which published in the Federal Register on September 22, 2009. That AD applies to Teledyne Continental Motors O-470, IO-470, TSIO-470, IO-520, TSIO-520, IO-550, and IOF-550 series reciprocating engines. The two references to the AD number are incorrect due to a software problem with the automated AD number assignment system. This document corrects those references. In all other respects, the original document remains the same.

This document corrects or clarifies a previously issued AD of the same number — it is not a separate, additional requirement. Its "Effective" date above may predate its own "Published" date because it restates the original AD's effective date.
