Summary
We propose to revise an existing airworthiness directive (AD) for the products listed above. This proposed AD results from mandatory continuing airworthiness information (MCAI) issued by an aviation authority of another country to identify and correct an unsafe condition on an aviation product and from a comment received from the European Aviation Safety Agency (EASA) on AD 2010-06-12, (75 FR 12439, March 16, 2010). The MCAI describes the unsafe condition as:
As a consequence of occurrences and service experience, Thielert Aircraft Engines GmbH has introduced a new rail pressure control valve part number (P/N) 05-7320-E000702 and has amended the Airworthiness Limitation Section (ALS) of the Operation & Maintenance Manual OM-02-02 to include a replacement of the rail pressure control valve. Failure of this part could result in in- flight shutdowns of the engine(s).
TAE has also amended the ALS of the Operation & Maintenance Manual OM- 02-01 to include a replacement ofthe rail pressure valve. We are proposing this AD to prevent engine in-flight shutdown, possibly resulting in reduced control of the aircraft.
