On February 22, 1994, about 1630 eastern standard time, a Cessna 150, N1665Q, registered to Vandenberg Airport Inc., operating as a 14 CFR Part 91 instructional flight, crashed on final approach for landing. Visual meteorological conditions prevailed at the time and no flight plan was filed. The airplane sustained substantial damage. The student pilot was not injured. The flight originated from Vandenberg Airport, Tampa, Florida, about 5 minutes before the accident. The student pilot stated he took off from runway 36 at about 1625, and remained in left closed traffic. A before landing check was completed on downwind, and flaps were extended to 30 degrees. He turned on base leg and extended the flaps to the full down position, and continued the turn to final approach. The airplane started to settle and the airspeed decreased. Throttle was increased and aft pressure was applied on the control yoke. The airplane stalled, pitched down, and collided with the terrain.
