NTSB Accidents

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.

Probable Cause: The inflight failure of the propeller blade due to fatigue cracking from corrosion pits.

Probable Cause: The pilot’s failure to discontinue an unstabilized approach, resulting in an aerodynamic stall and collision with terrain.

Probable Cause: The pilot’s failure to maintain airplane control during recovery from a bounced landing, which resulted in the exceedance of the airplane’s critical angle of attack and an aerodynamic stall.

Probable Cause: A total loss of engine power as a result of fuel contamination.

Probable Cause: The pilot’s failure to use carburetor heat during an extended ground delay before takeoff, which resulted in a total loss of engine power during initial climb due to carburetor ice.
