Probable Cause: The pilot’s failure to apply carburetor heat during the landing approach, which resulted in a loss of engine power from carburetor ice.

Probable Cause: The pilot’s failure to maintain directional control during landing in a gusting crosswind.

Probable Cause: Failure of the down limit and down indicator switch and the warning horn switch assemblies, which prevented the landing gear from extending and at the same time providing a false indication that the landing gear was extended.

Probable Cause: The engine electronic ignition system became disconnected, which resulted in a partial loss of engine power.

Probable Cause: The airplane owner/builder’s inappropriate use of a lower grade fuel than that required by the airplane and engine operations manual, which resulted in engine detonation and the degradation and eventual obliteration of the Nos. 1 and 2 cylinder spark plug electrode tips.

Probable Cause: The pilot’s failure to engage the turbocharger for takeoff and his improper decision to continue the takeoff with partial power, rather than reject the takeoff.

Probable Cause: A loss of engine power due to fuel exhaustion as a result of the pilot’s inadequate preflight planning. Contributing to the accident were the unreliable fuel quantity gauges and the improperly adjusted mixture control, which increased the fuel consumption above that anticipated by the owner’s manual.
