Dirt Ag Strip Airport
Aircraft Accident/Incident Report

Delta, Utah 84624
Monday, July 12, 1999 8:00 MDT

NTSB Narrative Summary Released at Completion of Accident

The pilot said that this was his first season as an aerial application pilot, and this was his first takeoff from this airstrip. He was on takeoff roll with 80 gallons of applicant and 30 gallons of fuel; and, the takeoff 'seemed long to me.' He reduced the throttle to idle, and began braking. The airplane went beyond the end of the runway, hit an earthen berm, and separated the right main landing gear from the fuselage. One propeller blade and the right wing tip were bent. The pilot reported that the airstrip's elevation was 5,000 feet, the temperature was 70 degrees F., and the altimeter was 30.02 inches of mercury. The density altitude was 6,795 feet. The airplane's maximum gross weight was 2,900 pounds, and the airplane's actual weight was undetermined.

NTSB Probable Cause Narrative

The pilot's delayed aborted takeoff. A factor was the high density altitude.
