NTSB Factual Report

The pilot reported that after landing and during the turn onto a taxiway intersection, he inadvertently raised the landing gear lever by mistake, rather than the adjacent flap lever. The left landing gear collapsed, which caused the left wing tip to strike the ground. The impact resulted in substantial damage to the left wing. The pilot stated that the accident could have been prevented had he waited until he was clear of the runway, stopped, and identified the flap switch. The pilot reported no preimpact mechanical malfunctions or failures with the airplane that would have precluded normal operation.

NTSB Probable Cause

The pilot inadvertently raised the landing gear lever rather than the adjacent flap level while exiting the runway which resulted in the retraction of the left main landing gear.
