Probable cause: The noninstrument-rated pilot’s improper decision to continue visual flight rules flight into instrument meteorological conditions, which resulted in controlled flight into terrain.

Probable cause: The pilot’s inability to avoid a collision with an unauthorized vehicle on the runway during the landing roll and the truck driver’s decision to cross the runway in front of the airplane.

Probable cause: The flight instructor’s failure to perform a go-around during final approach, which resulted in an aerodynamic stall and a hard landing. Contributing to the accident was the flight instructor’s failure to brief the student pilot on the positive transfer of aircraft control during preflight.

Probable cause: The pilot’s improper decision to take off with a known fuel leak, which resulted in a loss of engine power due to fuel exhaustion.

Probable cause: The pilot’s failure to maintain a safe distance between the airplane and a person on the ground, which resulted in serious injuries to the person.

Probable cause: The pilot’s decision to continue to attempt to take off despite the airplane’s inability to attain a positive climb rate, which resulted in little runway remaining, and his subsequent decision to turn off the runway, whic

Probable cause: The pilot’s difficulty controlling the airplane due to his incorrect reinstallation of the wings, which led to a bounced precautionary landing. Contributing to the accident was the failure of the pilot and the mechanic to veri

Probable cause: The pilot’s failure to maintain directional control during the takeoff roll with gusting wind conditions.
