NTSB Accidents

Probable cause: The pilot’s selection of an empty fuel tank for takeoff, which resulted in fuel starvation and the subsequent total loss of engine power.

Probable cause: The pilot’s failure to properly secure his seat before initiating the takeoff, which resulted in the seat sliding back as the airplane accelerated during takeoff, his inability to reach the pedals, and the subsequent loss of directional control and impact with trees and shrubs.

Probable cause: An impact with terrain for reasons that could not be determined based on the available information.

Probable cause: Maintenance personnel’s improper installation of the muffler attachment hardware, which resulted in the muffler separating in flight, thermal damage that interrupted the magnetos’ function, and the subsequent total loss of engine power.

Probable cause: The inability of the pilot of the Piper and the student pilot and flight instructor of the Diamond to see and avoid the other airplane. Contributing to the collision was the Piper pilot’s failure to use the correct common traffic advisory frequency to announce his airplane’s position.

Probable cause: Fatigue failure of the No. 1 cylinder intake valve, which resulted in the loss of engine power.

Probable cause: The accumulation of carburetor ice before takeoff, which resulted in a partial loss of engine power on initial climb and a forced landing on unsuitable terrain.

Probable cause: The total loss of engine power for reasons that could not be determined based on the available evidence.

Probable cause: A fuel leak from the carburetor float bowl due to a missing plug, which resulted in excessive fuel consumption and a total loss of engine power due to fuel exhaustion. Contributing to the accident was the pilot’s decision to depart on the accident flight leg after noting the airplane’s unexpectedly high fuel consumption during the previous leg.
