Parowan, Utah 84761
Thursday, September 27, 2001 9:00 MDT

NTSB Narrative Summary Released at Completion of Accident

The pilot said that he completed an application pass, and turned his head to look for his flagman. He said there was rising terrain in front of him, and he immediately applied full power. The airplane began losing airspeed, and he was unable to increase the climb rate. The airplane impacted the ground in a rough ravine. The left wing spar was bent up and the fuselage was wrinkled. The calculated density altitude was 9,736 feet.

NTSB Probable Cause Narrative

the pilot's failure to maintain adequate airspeed which resulted in an inadvertent stall/mush into terrain. Contributing factors were the pilot's diverted attention, the rising terrain, and the high density altitude weather condition.
