Federal Aviation Administration / Flight Standards District Office; Lubbock, Texas

Aviation Accident Final Report - National Transportation Safety Board:

Investigation Docket - National Transportation Safety Board:

Location: Paducah, TX
Accident Number: GAA19CA317
Date & Time: 06/05/2019, 1120 CDT
Registration: N78641
Aircraft: Piper PA 11
Aircraft Damage: Substantial
Defining Event: Loss of control on ground
Injuries: 1 None
Flight Conducted Under: Part 91: General Aviation - Positioning 


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. 

Probable Cause and Findings

The National Transportation Safety Board determines the probable cause(s) of this accident to be:
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.


Directional control - Not attained/maintained (Cause)

Personnel issues
Use of equip/system - Pilot (Cause)

Environmental issues
Crosswind - Effect on operation (Cause)
