Aircraft Accident/Incident Report
Mckinney, Texas 75069
Sunday, December 25, 2005 16:30 CST
NTSB Narrative Summary Released at Completion of Accident
The 3,500-hour private pilot departed Runway 36, (a 1,850-feet long by 75-feet wide grass/turf runway) and made a sharp right turn to avoid the airspace of an airport located 4 miles to the south. During the turn, the pilot's new helmet and goggles were blown away from his face by the airstream. The biplane then stalled, spun to the right, and impacted terrain. The airplane came to rest on its nose, inverted, with the tail of the airplane leaning against a telephone pole. The pilot disconnected his harness and egressed the airplane as a post-impact fire ensued. The pilot was uninjured. In the recommendation section of the Pilot/Operator Aircraft Accident Report (NTSB Form 6120.1/2), the pilot recommended that the accident could have been prevented had an adequate preflight been performed, and had he maintained an appropriate angle of attack to avoid the stall.
NTSB Probable Cause Narrative
The pilot's failure to maintain directional control and airspeed, which resulted in an inadvertent stall. A contributing factor was the pilot's helmet and goggles shifting while maneuvering.
