Accident Details

The accident occurred during a night takeoff from runway 28, which is 2501 feet long. The pilot, who was not instrument rated, reported a fog layer 60 to 100 feet thick at the airport. A witness and one passenger also reported heavy fog during the takeoff.

Sequence of Events

The pilot initiated the takeoff with the flaps set at 10 degrees. During the takeoff roll, he noted that the engine tachometer did not exceed 2300 rpm and the venturi-operated attitude indicator did not activate. After liftoff, the pilot climbed at 65 knots and retracted the flaps when he realized the airplane lacked sufficient climb performance. He then observed trees in his path and was unable to climb above them. He pitched the airplane up, and the tail struck the trees.
