What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
(-23) On June 22, 2009 N735BB at 1909Z at kgkj Port Meadville Airport. N735BB a Beechcraft J-35 sn D5557 owned and operated by privacy data omitted private pilot 3070386 received incident damage limited to the propeller, tip tanks, landing gear doors and belly skin. On 6-22-2009 the pilot and one passenger were interviewed. Both stated the gear was down and landing was normal then during rollout the landing gear collapsed. During our assessment of the aircraft damage I noticed an unapproved repair to the landing gear up and down switch. On 6-26-2009 I returned to gkj assisted by inspector hochendoner, placed aircaft on jacks and checked gear operation, found nose gear actuator bent and right main would not go completely down and the main gear struts would not compress. The fact that the main struts would not compress did not let the landing gear safety switch work, this coupled with the unapproved cockpit repair allowed the gear to retract on the ground. Further the bent nose gear actuator and the right main not able to go full down are consistent with trying to extend the gear after realizing the error.

THE FACT THAT THE MAIN STRUTS WOULD NOT COMPRESS DID NOT LET THE LANDING GEAR SAFETY SWITCH WORK, THIS COUPLED WITH THE UNAPPROVED COCKPIT REPAIR ALLOWED THE GEAR TO RETRACT ON THE GROUND.
