A BE35 PLT LNDG AT ZZZ; US; EXPERIENCED A LNDG GEAR FAILURE DURING ROLLOUT ON RWY 17.

Narrative

THE ARPT IS A PVT AIRSTRIP. THE RWY IS RWY 17/35 AND IS 40 FT BY 3200 FT PAVED. IT IS AN UPSLOPE IN BOTH DIRECTIONS. THE LONGEST SLOPE IS ON RWY 35 (HIGH POINT IS OFF CTR TO THE N). I WAS DOING A LNDG ON RWY 17 WITH A K-MODEL BONANZA. THERE WAS A QUARTERING HEADWIND FROM THE SW. I HAD ANOTHER BONANZA PLT WITH ME AT THE TIME THAT CAN VERIFY THE FOLLOWING EVENTS. THERE WAS ALSO AN FAA ACCIDENT SAFETY PREVENTION COUNSELOR THAT WAS PRESENT ON THE FIELD. AFTER LNDG ON RWY 17 AND ROLLING OUT TO THE CREST OF THE RWY; THE LNDG GEAR COLLAPSED NEAR THE TOP OF THE HILL. IT APPEARS THE L MAIN COLLAPSED FOLLOWED BY THE NOSE THEN THE R MAIN. THERE WERE SEVERAL WITNESSES THAT SAID THEY HEARD A LOUD POPPING SOUND JUST PRIOR TO THE GEAR GIVING AWAY. THE LNDG GEAR SELECTOR AND FLAPS WERE STILL IN THE DOWN POS AFTER LNDG. THERE WAS SOME FLAP DAMAGE DURING CONTACT WITH THE GND. WE MOVED THE AIRPLANE TO A GRASS AREA TO CLR THE RWY. IN DOING SO WE RAISED THE FLAPS; SO WE COULD SLIDE THE AIRPLANE ON THE GRASS. SINCE THERE WERE NO INJURIES OR SUBSTANTIAL STRUCTURAL DAMAGE AS STATED IN THE NTSB PART 8.30; THIS IS NOT A REPORTABLE ACCIDENT. ROOT CAUSE OF THE GEAR COLLAPSE IS STILL TO BE DETERMINED. CORRECTIVE ACTIONS WILL BE TAKEN; BASED ON THE FINDINGS BY THE MECH; AFTER PLANE IS INSPECTED.
