FAA issues emergency AD for Thielert engines
By AOPA ePublishing staff

In-flight engine shutdowns have led the FAA to issue an emergency
airworthiness directive (AD) for model TAE 125-02-99 engines from
Thielert. The shutdowns were the result of cracks in the high-pressure
fuel lines caused by excessive vibration.

The March 12 AD affects engines with serial numbers from 02-02-1500
through 02-02-2279. The engines are installed on Cessna 172, Diamond
DA42, and other aircraft.

Before the next flight, owners must install a new high-pressure fuel
line and bracket. Special flight permits are allowed for a single VFR
flight of up to two hours to the nearest maintenance station.
