A witness reported an aircraft with cargo filled to the ceiling experienced a short takeoff roll, nose-high attitude, and subsequent loss of control, culminating in an inverted dive into the ground.

Witness Account

According to a witness who observed the pilot and a passenger load the airplane and take off, the cargo area was completely filled up to the ceiling of the aircraft. The witness noted that the takeoff roll was short.

Takeoff and Initial Climb

Immediately after lifting off, the airplane rose with a very nose-high attitude until reaching an altitude of approximately 100 feet above the ground. The witness stated that the pilot appeared to be having trouble keeping the nose of the aircraft down.

Loss of Control and Collision
