NTSB

Probable Cause: A loss of engine power due to the formation of carburetor ice that resulted from the pilot’s delayed use of carburetor heat during the landing approach.

Probable Cause: The pilot’s failure to maintain control of the airplane while initiating a low-altitude aerobatic maneuver, which resulted in impact with trees and terrain. Contributing to the accident was the pilot’s high-risk behavior.

Probable Cause: The premature retraction of the flaps by the student pilot, while just above the airplane’s stall speed. Contributing to the accident was the flight instructor’s inadequate supervision and failure to regain aircraft control from the student pilot.

Probable Cause: The pilot’s failure to properly adjust the propeller’s pitch angle, which resulted in a loss of thrust and an inability to maintain altitude.

Probable Cause: The pilot’s loss of directional control during landing rollout due to interference from the pilot’s foot/shoe with the airplane structure that resulted in a runway excursion and impact with terrain.

Probable Cause: The pilot’s unsafe inflight operation of the airplane and failure to maintain clearance from a person on the ground, which resulted in a serious injury.

Probable Cause: Maintenance personnel’s failure to properly torque and inspect the magneto hardware, which resulted in a partial loss of engine power.

Probable Cause: The pilot’s decision to attempt an unfamiliar takeoff technique, his failure to maintain pitch control during takeoff, and his subsequent decision to retract flaps at a low altitude, which resulted in a descent into a building.
