What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
(-23) Pilot was leading a formation flight of four aircraft. After landing and making a 180 degree turn to back-taxi to exit the runway, pilot was distracted and while reaching for what he thought was the flap control, grabbed the gear handle by mistake and the landing gear was retracted. The aircraft sustained minor damage to the wing tip and right outboard portion of the flap as well as damage to the propeller.
