We propose to adopt a new airworthiness directive (AD) for all TAE 125-02-99 and TAE 125-02-114 reciprocating engines. This proposed AD was prompted by an in-flight shutdown of an airplane equipped with a TAE 125-02-99 engine. This proposed AD would require inspection of the oil filler plug vent hole at the next scheduled maintenance or within 110 flight hours after the effective date of this AD. If chips are found to be blocking the vent hole, additional corrective action is required before next flight. We are proposing this AD to prevent engine in-flight shutdown or power loss, possibly resulting in reduced control of the airplane.
