Ocotillo Airport
Aircraft Accident/Incident Report

Ocotillo Wells, California 92259
Wednesday, May 4, 1994 12:28 PDT

NTSB Narrative Summary Released at Completion of Accident

The aircraft was known to be susceptible to accumulated water in its tanks and the pilot had experienced previous engine stoppage during takeoff as a result of water in the fuel. The flight before the accident terminated in a precautionary landing at Ocotillo after experiencing a rough running engine. The pilot removed the carburetor, had it serviced, and then reinstalled it himself. After reinstallation, the pilot performed a ground run-up and the aircraft reportedly ran normally. On the day of the accident, the pilot performed a normal preflight. He drained 1 gallon of fuel from the aircraft's gascolator, since there are no quick-drain sumps on either main fuel tank. Immediately on takeoff, the aircraft's engine began to sputter and lose power. The pilot told a ground observer by radio that he wanted to try to gain some altitude and see if the problem would clear up. While in a turn near the ground, the aircraft stalled and crashed next to the runway. Water was found in the carburetor bowl.

NTSB Probable Cause Narrative

the failure of the pilot to maintain flying speed after experiencing a partial power failure while maneuvering. A factor in the accident was the failure of the pilot to drain accumulated water from the aircraft fuel system during the preflight inspection.
