Location: Heber, UT
Accident Number: GAA19CA301
Date & Time: 06/01/2019, 1645 MDT
Registration: N2689K
Aircraft: Luscombe 8
Aircraft Damage: Substantial
Defining Event: Aerodynamic stall/spin
Injuries: 1 None
Flight Conducted Under: Part 91: General Aviation - Personal 

The pilot of the tailwheel-equipped airplane reported that, during the landing roll in a gusting crosswind, the airplane veered to the left. He added right rudder, which slowed the veer, but observed that the airplane was going to depart the runway. He added full power and right rudder to abort the landing. The airplane became airborne, but "stopped the climb, and slid tail first onto the ground." The right main landing gear collapsed, and the propeller and the right wing struck the ground.

The airplane sustained substantial damage to the right wing.

The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.

The airport's automated weather observation station reported that, about 10 minutes before the accident, the wind was from 010° at 10 knots. The same automated station reported that, about 10 minutes after the accident, the wind was from 340° at 14 knots. The pilot landed the airplane on runway 04.

It is likely that during the aborted landing, the pilot aerodynamically stalled the airplane.
