## Summary

We propose to adopt a new airworthiness directive (AD) for certain Continental Motors, Inc. (CMI) TSIO-550-K, TSIOF-550-K, TSIO- 550-C, TSIOF-550-D, and TSIO-550-N reciprocating engines. This proposed AD was prompted by a report of an uncommanded in-flight shutdown (IFSD) resulting in injuries and significant airplane damage. This proposed AD would require replacing the oil cooler cross fitting assembly. We are proposing this AD to prevent failure of the oil cooler cross fitting and engine, IFSD and loss of the airplane.
