Aviation Accident Summary LAX00LA233

COLEVILLE, CA, USA

Aircraft #1

N8578L

Piper PA-25-260

Analysis

The commercial pilot was attempting to tow a sailplane out from a field. The sailplane pilot had lost lift and made a precautionary landing, and contacted the tow plane company for assistance. After landing the tow plane in the open field, both pilots paced off about 15/1,600 feet, which the tow pilot estimated would be sufficient for takeoff at 5,300 feet msl. The density altitude was calculated to be about 7,903 feet msl. During the takeoff climb the tow plane collided with a fence. The sailplane released, overflew the tow plane about 2 to 4 feet, and collided with another fence.
