Additional Participating Entity:
Federal Aviation Administration / Flight Standards District Office; Lincoln, Nebraska

Aviation Accident Factual Report - National Transportation Safety Board:

Investigation Docket - National Transportation Safety Board:

Location: Grand Island, NE
Accident Number: GAA18CA577
Date & Time: 09/18/2018, 1730 CDT
Registration: N811YD
Aircraft: Aviat A1
Aircraft Damage: Substantial
Defining Event: Loss of control on ground
Injuries: 1 None
Flight Conducted Under: Part 91: General Aviation - Personal 

The pilot of the tailwheel-equipped airplane reported that, during the second flight of the day, which was a 3 hour 30 minute flight, the tower controller at the destination airport instructed him to land on runway 35. During the landing roll, he lost directional control, the airplane ground looped to the right, and the left wing impacted the ground.

The pilot added that he believed the accident was a result of fatigue. He added that he should have requested runway 13, which would have reduced the crosswind component, rather than accept the runway assigned.

The airplane sustained substantial damage to the left wing and left aileron.

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

The automated weather observation station located on the airport reported that, about 37 minutes before the accident, the wind was from 100° at 12 knots. The same automated station reported that, about 23 minutes after the accident, the wind was from 100° at 12 knots, gusting to 22 knots. The airplane landed on runway 35.
