Location: Blairsville, Georgia 
Accident Number: GAA19CA373
Date & Time: May 19, 2019, 13:00 Local
Registration: N153SW
Aircraft: Flight Design CTSW
Aircraft Damage: Substantial
Defining Event: Loss of control in flight 
Injuries: 2 None
Flight Conducted Under: Part 91: General aviation - Personal

Analysis

The pilot reported that, while on approach for landing on runway 26, the wind was reported to be from 240º at 8 knots. One second later, the wind shifted and was from 180º at 6 knots. The pilot flew the final approach with a left crosswind and crossed the threshold at 50 knots. As he leveled the airplane and was about to touch down at 45 knots, the airplane lifted about 7 ft, and the nose pitched up 20º. The pilot pushed the control stick forward and began to add power, but the airplane "violently slammed" onto the runway, and the left main landing gear collapsed. He added full right rudder and aileron to keep the airplane on the runway, but it veered left into tall grass. The airplane sustained substantial damage to the firewall and engine mount.

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 airplane control during landing in gusting crosswind conditions, which resulted in a hard landing and landing gear collapse. 

Findings

Personnel issues Aircraft control - Pilot
Aircraft (general) - Not attained/maintained
Environmental issues Gusts - Effect on operation
Environmental issues Crosswind - Effect on operation
