Probable cause

The pilot's failure to maintain directional control during the landing on a road in crosswind conditions, which resulted in the airplane exiting the road and subsequently nosing over.

Findings · 4

NTSB’s coded findings. Those marked are part of the probable cause; the rest are factors or other findings. Under each, the cases with the same finding.

Sequence of events

The events NTSB coded, in order, by phase of flight. The defining event is the one that best describes the accident. Under each, the cases with the same event anywhere in their sequence.

Analysis

The pilot of the tailwheel-equipped airplane reported that he was concerned about the condition of the landing and taxi surfaces of the private, grass airstrip due to heavy rainfall. He overflew the field but was unable to determine the condition. He determined that it would be safer to land on a road perpendicular to the runway. Upon landing on the road, the airplane suddenly veered right. The pilot applied opposite rudder, but the airplane exited the road and nosed over. The airplane sustained substantial damage to the left wing lift strut and rudder. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation. The pilot reported that the wind was from 360° at 7 knots. The pilot was landing the airplane to the west.

Factual narrative

The pilot of the tailwheel-equipped airplane reported that he was concerned about the condition of the landing and taxi surfaces of the private, grass airstrip due to heavy rainfall. He over flew the field but was unable to determine the condition. He determined it would be safer to land on the "Farm Road" perpendicular to the runway. Upon landing on the road, the airplane suddenly veered to the right, he applied opposite rudder, but the airplane exited the road, and nosed over. The airplane sustained substantial damage to the left wing lift strut and rudder. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation. The pilot reported that the wind was from 360° at 7 knots. The airplane was landing to the west.
