Location: Talkeetna, AK
Accident Number: ANC17CA023
Date & Time: 05/13/2017, 1730 AKD
Registration: N9726N
Aircraft: WSK-PZL WARZAWA-OKECIE PZL 104 WILGA 80
Aircraft Damage: Substantial
Defining Event: Loss of control on ground
Injuries: 1 None
Flight Conducted Under: Part 91: General Aviation - Ferry 

The pilot of a tailwheel-equipped airplane stated that during the landing roll the airplane veered slightly left of the runway centerline. To correct for the veer, the pilot applied right rudder, and the airplane subsequently veered to the right. The pilot was unable to regain directional control, and the airplane continued off the right side of the runway encountering soft gravel which resulted in a rapid right ground loop. The left landing gear leg fractured and the left wing and elevator impacted the runway surface substantially damaging the left aileron and fuselage.

The pilot stated that he had no experience flying this model of airplane on wheels. According to the airplane owner, the PZL-104 Wilga's rudder and brake system are unique and can be difficult to operate. The pilot reported no pre-impact mechanical malfunctions or anomalies that would have precluded normal operation.
