NTSB

Probable cause: The pilot’s inadvertent landing gear retraction during approach.

Probable cause: The pilot’s diverted attention to his phone while maneuvering at a low altitude, which resulted in collision with terrain.

Probable cause: The pilot’s improper wind correction inputs while taxiing with a quartering tailwind.

Probable cause: The control stick handgrip separation from the control stick resulting in the airplane pitching forward, which resulted in hard landing.

Probable cause: The pilot’s decision to takeoff in gusting wind conditions with insufficient rotor rpm.

Probable cause: The ground vehicle driver’s decision to drive on an active taxiway at night and failure to yield to taxiing aircraft, resulting in a collision with a taxiing aircraft.

Probable cause: The pilot’s inadequate preflight fuel planning and in-flight fuel monitoring and his decision to take off with an unverified amount of fuel, which resulted in fuel exhaustion and a subsequent impact with trees during an attempted forced landing.

Probable cause: The total loss of engine power for reasons that could not be determined.

Probable cause: The student pilot’s failure to maintain directional control during landing.
