NTSB Accidents

Probable Cause: A total loss of engine power due to fuel starvation as a result of the pilot’s modifications to the fuel system. Contributing to the accident was the pilot’s decision to continue the takeoff despite observing lower than anticipated propeller rpm, his decision to delay his precautionary landing to allow another airplane to land, and his decision to conduct flight testing of the airplane following multiple modifications.

Probable Cause: The pilot’s exceedance of the airplane’s critical angle of attack during the takeoff, which resulted in an aerodynamic stall and loss of airplane control at too low of an altitude to recover.

Probable Cause: The pilot’s exceedance of the airplane’s critical angle of attack, which resulted in an aerodynamic stall and loss of aircraft control.

Probable Cause: The stabilator trim rod assembly separated from the stabilator link assembly due to a missing connecting bolt, which resulted in the pilot’s inability to maintain pitch control of the airplane.

Probable Cause: The pilot’s failure to remove the wheel chocks before engine start which resulted in the inadvertent contact with the propeller while the engine was running.

Probable Cause: A total loss of engine power caused by fatigue cracking and fracture of the crankshaft due to severe wear of the bearings.

Probable Cause: Maintenance personnel’s failure to detect the corroded aileron cable during recent inspections, which resulted in the separation of the aileron control cable and a subsequent loss of airplane control during takeoff.

Probable Cause: The pilot’s failure to apply carburetor heat before initiating a descent in conditions conducive to the development of carburetor icing, which resulted in a partial loss of engine power due to carburetor ice.

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.
