### AGENCY: Federal Aviation Administration (FAA), DOT. ACTION: Final rule. SUMMARY: We are adopting a new airworthiness directive (AD) for all Thielert Aircraft Engines GmbH (TAE) TAE 125-02-99 and TAE 125-02-114 reciprocating engines . This AD requires 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. This AD was prompted by an in-flight shutdown of an airplane equipped with a TAE 125-02-99 engine. We are issuing this AD to prevent engine in-flight shutdown or power loss , possibly resulting in reduced control ofthe airplane. DATES: This AD becomes effective [Insert date 35 days after date of publication in the by reference of certain publications listed in this AD as of [Insert date 35 days after date ofpublication in the FEDERAL REGISTER].
