NTSB Accidents

Probable cause: The structural failure of both wings’ leading-edge slats, which resulted in a loss of airplane control.

Probable cause: A loss of engine power for reasons that could not be determined based on the available information.

The pilot’s failure to maintain an adequate glidepath during landing, which resulted in an unintended touchdown before the chosen landing area.

Probable cause: The pilot’s fuel mismanagement, which resulted in fuel starvation to both engines and their subsequent loss of engine power.

Probable cause: The student pilot’s failure to maintain an appropriate descent rate and runway alignment during the landing flare, which resulted in the airplane touching down left of the runway and hitting a ditch.

Probable cause: The failure of the second airplane’s pilot to see and avoid the first airplane as he was overtaking the first airplane.

Probable cause: The pilot/mechanic’s failure to maintain airspeed following a loss of engine power, which resulted in the airplane exceeding its critical angle of attack and experiencing an aerodynamic stall. Also causal was the pilot/mechanic’s failure to service the engine with oil following maintenance, which resulted in the total loss of engine power.

Probable cause: The failure of the landing gear system to either fully retract or extend due to a cracked hydraulic fitting flare, which resulted in the loss of hydraulic pressure.

Probable cause: The pilot’s failure to maintain adequate separation and visual lookout during landing, which resulted in his airplane colliding with the airplane ahead of it on the runway.
