Date & Time: 11/09/2018, 1002 PST

Aircraft: Cessna A185
Aircraft Damage: Substantial
Defining Event: Loss of control on ground

Flight Conducted Under: Part 91: General Aviation - Instructional 

Analysis 

The flight instructor was evaluating a pilot receiving instruction in a tailwheel-equipped, high‑performance airplane for a visual flight rules cross-country flight. He added that they considered the runway to be "a one-way strip." When they arrived at the private airstrip, the GPS indicated a 5-knot crosswind from the southeast.

During the approach, the airplane was about "50 ft high" when it crossed their predetermined go‑around point; they continued the landing. During the touchdown, the airplane bounced twice, and the pilot then initiated a go‑around. The instructor then "reminded" the pilot that they were committed to the landing and instructed him not to go-around, so the pilot transitioned the airplane back to landing.

During the subsequent touchdown, the airplane "quickly" veered right. The pilot attempted to correct the veer, but the airplane exited the right side of the airstrip onto soft ground, and it then nosed down and came to rest on the spinner and left wing.

The airplane sustained substantial damage to the left wing.

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

The pilot indicated that the wind at the airport was from about 140° at 5 knots. The pilot landed the airplane on runway 5.

The flight instructor recommended that he should have taken the controls sooner in the abnormal situation. 

Probable Cause and Findings

The National Transportation Safety Board determines the probable cause(s) of this accident to be:
The pilot receiving instruction's improper approach and landing flare in crosswind conditions, which resulted in a bounced landing and subsequent loss of directional control. Contributing to the accident was the flight instructor’s delayed remedial action. 

Findings

Aircraft
Landing flare - Not attained/maintained (Cause)
Directional control - Not attained/maintained (Cause)

Personnel issues
Aircraft control - Student pilot (Cause)
Delayed action - Instructor/check pilot (Factor)

Environmental issues
Crosswind - Effect on operation
