Location: Yakima, WA
Accident Number: GAA19CA167
Date & Time: 03/15/2019, 1630 PDT
Registration: N767CC
Aircraft: Cub Crafters CC18
Aircraft Damage: Substantial
Defining Event: Loss of control on ground
Injuries: 2 None
Flight Conducted Under: Part 91: General Aviation - Instructional 


The pilot receiving instruction in the tailwheel-equipped airplane reported that, during the landing roll of a touch-and-go landing, he added slight right correction followed by left correction. The airplane veered left, and the pilot added full right rudder, but the airplane ground looped to the left. The right main landing gear collapsed, and the right wing struck the ground.

The airplane sustained substantial damage to the right wing.

The flight instructor 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 23 minutes after the accident, the wind was from 170° at 6 knots. The pilot landed the airplane on runway 27.

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 landing, which resulted in a ground loop, and the flight instructor's delayed remedial action.


Aircraft Directional control - Not attained/maintained
Personnel issues Delayed action - Instructor/check pilot
Personnel issues Use of equip/system - Student/instructed pilot
