What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
(-23) While practicing multiple power-off 180 degree accuracy approach and landings, the pilot failed to lower the aircraft landing gear resulting in a gear up landing. The aircraft sustained minor damage to the propeller, flaps, and gear doors. The pilot stated that the incident occurred after completing approximately eleven takeoff and landings, and believes that he was distracted by a radio call from another aircraft entering the uncontrolled airport traffic pattern just prior to completing his checklist items. The pilot stated that, due to his performing numerous traffic patterns while practicing, he had been completing the before landing checklist items by memory. The aircraft was equipped with an approved manufacturers, and approved pilot school, cockpit checklist. The pilot did not remember hearing the landing gear warning horn until just before the aircraft touched down. A microswitch in the PA-28R-201 throttle quadrant will activate the landing gear warning horn when the gear is up and power is reduced below 14 inches of manifold pressure.

THE AIRCRAFT SUSTAINED MINOR DAMAGE TO THE PROPELLER, FLAPS, AND GEAR DOORS. THE PILOT STATED THAT THE INCIDENT OCCURRED AFTER COMPLETING APPROXIMATELY ELEVEN TAKEOFF AND LANDINGS, AND BELIEVES THAT HE WAS DISTRACTED BY A RADIO CALL FROM ANOTHER AIRCRAFT ENTERING THE UNCONTROLLED AIRPORT TRAFFIC PATTERN JUST PRIOR TO COMPLETING HIS CHECKLIST ITEMS. THE PILOT STATED THAT, DUE TO HIS PERFORMING NUMEROUS TRAFFIC PATTERNS WHILE PRACTICING, HE HAD BEEN COMPLETING THE BEFORE LANDING CHECKLIST ITEMS BY MEMORY. THE AIRCRAFT WAS EQUIPPED WITH AN APPROVED MANUFACTURERS, AND APPROVED PILOT SCHOOL, COCKPIT CHECKLIST.
