Airworthiness Directive · Amendment 39-18685 · Continental Motors, Inc. Reciprocating Engines
Continental Motors, Inc. Reciprocating Engines
This AD applies to Continental Motors, Inc. (CMI) TSIO-550-K, TSIOF-550-K, TSIO-550-C, TSIOF-550-D, and TSIO-550-N reciprocating engines with an engine serial number below 1012296 and an oil cooler cross fitting, part number AN918-1J or AN918-2J, installed.
We are adopting 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 AD was prompted by a report of an uncommanded in-flight shutdown (IFSD) resulting in injuries and significant airplane damage. This AD requires replacing the oil cooler cross fitting assembly. We are issuing this AD to prevent failure of the oil cooler cross fitting and engine, IFSD, and loss of the airplane.
(1) Within 12 months or 100 flight hours after the effective date of the AD, whichever occurs first, replace the oil cooler cross fitting, nipple, and bushing. Use the Action Required paragraphs III.1 through III.8 of CMI Critical Service Bulletin (CSB) CSB15-2, Revision C, dated November 9, 2015 (also referred to as CMI CSB CSB15-2C, dated November 9, 2015), or the Action Required paragraphs III.1 through III.8 of CMI CSB CSB15-7, Revision B, dated April 26, 2016 (also referred to as CMI CSB15-7B, dated April 26, 2016), to perform the replacement.
(2) Reserved.
