AGENCY: Federal Aviation Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: We are adopting a new airworthiness directive (AD) for all Thielert 

Aircraft Engines GmbH (T AE) T AE 125-02-99 and T AE 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].
