Dozier Airstrip Airport
Aircraft Accident/Incident Report
Prescott, Washington 99348
Wednesday, July 21, 2010 6:20 PDT
NTSB Narrative Summary Released at Completion of Accident
The pilot reported that he flew into a private airstrip and encountered no problems with the airframe or engine. He loaded 375 gallons of spray mixture and reported that there was no indication of a problem until after liftoff, when the airplane settled back onto the airstrip, although the engine did not lose power. The pilot verified the power readings and determined that there was insufficient runway remaining to abort the takeoff. The airplane lifted off again and crossed a gravel road that was perpendicular to the runway before settling into a fallow field that was across the road. The pilot completed an emergency release of the spray mixture but was unsuccessful in getting airborne prior to colliding with an electric fence. After hitting the fence, he aborted the takeoff. The pilot reported that the airfield was flat, the wind was calm, and the temperature was cool. The airplane was operating below maximum gross weight during the takeoff, and the pilot’s reported instrument and visual perceptions were the same as many other takeoffs that he had made from this airstrip. During a postaccident engine examination, no anomalies were identified that would have precluded normal operation.
NTSB Probable Cause Narrative
The airplane’s inability to maintain a positive rate of climb after takeoff for undetermined reasons. Contributing to the accident was the pilot’s delayed reaction to initiate an emergency release of the spray mixture.
