In-flight engine shutdowns have led the FAA to issue an emergency airworthiness directive (AD)[http://download.aopa.org/epilot/2008/20080652ad.pdf] 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.

Mission Statement

Every month: news, facts, and comments on the coming revolution for piston-engines aircrafts between 130 and 400 HP: Retrofitting a diesel engine to run on Jetfuel or Kerosene, reduce Gallons/Hour by some 30%, eliminate ignition systems (magnetos, spark plugs) and their problems, eliminate mixture control, increase TBO to 2,400-3,000 hours, increase performance between 6,000 and 12,500 ft., and drastically reduce Operating Costs.

The letter is intended for piston engines aircraft owners, manufacturers, fleet operators and FBOs, re-manufacturers of engines for these aircrafts, manufacturers of engine components and ancillaries, and all professionals acting in decisions of engine exchange or refitting at TBO, in North and South America, Pacific Rim, African continent, and all parts of the world were Avgas, Mogas, Kerosene and Jetfuel are available.
