Type:Silhouette image of generic DH82 model; specific model in this crash may look slightly different
de Havilland DH.82A Tiger Moth
Registration: N28681
C/n / msn: PG621-81
Fatalities:Fatalities: 0 / Occupants: 2
Aircraft damage: Written off (damaged beyond repair)
Location:Peach State Airport (GA2), Williamson, GA -   United States of America
Phase: Manoeuvring (airshow, firefighting, ag.ops.)
Departure airport:Williamson, GA (GA2)
Destination airport:Williamson, GA (GA2)
Investigating agency: NTSB
According to the pilot, the airplane’s engine power and performance were “good,” and the airplane demonstrated its “gentle” handling characteristics through both left and right 30-degree banking turns. The airplane crossed the airport about traffic pattern altitude and then entered a vertical, nose-down descent. The pilot reported that he could not recall how the airplane transitioned from level flight to a nose-down descent. However, it is likely that the pilot did not maintain airspeed and that the airplane exceeded its critical angle-of-attack. During the descent, the pilot held the control stick fully aft, and the elevator gained enough authority to allow him to level the airplane just above ground level as he flew it between a parked airplane and the airport restaurant. The airplane then collided with a flagpole, the restaurant, and terrain before coming to rest upright. The pilot said that, once the airspeed increased sufficiently during the descent, he had full flight control authority. He reported that there were no mechanical deficiencies with the airplane that would have precluded normal operation.

Probable Cause: The pilot’s failure to maintain airspeed while maneuvering, which led to the airplane exceeding its critical angle-of-attack and experiencing an aerodynamic stall at an insufficient altitude to fully recover before collision with obstacles and terrain.
