Probable cause

The pilot's failure to check for fuel contamination during the preflight inspection, which resulted in a loss of engine power shortly after takeoff due to water contamination. Contributing factors to the accident included the rough/uneven field and the collapse of the main landing gear.

Sequence of events

NTSB’s coding before 2008: each occurrence and phase of flight, and the causes and factors under it. The codes are defined in NTSB’s coding manual.

Analysis

The agricultural airplane was substantially damaged during a forced landing. The pilot reported that after liftoff the engine began to experience a loss of power. The pilot initiated a turn back toward the airport as the engine continued to lose power. The pilot elected to dump the airplane's chemical load prior to executing a forced landing in a field. The main landing gear separated from the airplane during the landing which resulted in wing and propeller damage. Subsequent to the accident, water contamination was found in the service tank used to fuel the accident airplane. Additionally, water contamination was found in the airplane's fuel system.
