What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
(-23) The pilot reported that the left main landing gear (MLG) began to slowly collapse during landing rollout on runway 04 at vrb. The airplane gradually veered left and came to a stop at the runway edge just past taxiway B1. Initial on-scene inspection of the airplane by the airport manager and a local mechanic revealed that the nose gear and right main gear were fully extended, both inboard MLG doors were in the closed position, and the cockpit control was in the down position. Preliminary on-site examination of the airplane by the FAA iic after removal from the runway revealed what appeared to be overstress failures on the left MLG extension/retraction bellcrank assembly and the gear strut trunnion: the bellcrank rod end at the down-lock support brace was bent inboard and separated into two pieces, a bellcrank pivot attach point bolt had fractured and separated from the top of the MLG trunnion, and the lower part of one of the trunnion attachment "ears" was partially missing. Unaided visual examination of the fracture surfaces revealed features typical of an instantaneous (overload) failure mode, including a dull, fibrous fracture texture, shape change, and shear lips.
As the FAA filed it
(-23) THE PILOT REPORTED THAT THE LEFT MAIN LANDING GEAR (MLG) BEGAN TO SLOWLY COLLAPSE DURING LANDING ROLLOUT ON RUNWAY 04 AT VRB. THE AIRPLANE GRADUALLY VEERED LEFT AND CAME TO A STOP AT THE RUNWAY EDGE JUST PAST TAXIWAY B1. INITIAL ON-SCENE INSPECTION OF THE AIRPLANE BY THE AIRPORT MANAGER AND A LOCAL MECHANIC REVEALED THAT THE NOSE GEAR AND RIGHT MAIN GEAR WERE FULLY EXTENDED, BOTH INBOARD MLG DOORS WERE IN THE CLOSED POSITION, AND THE COCKPIT CONTROL WAS IN THE DOWN POSITION. PRELIMINARY ON-SITE EXAMINATION OF THE AIRPLANE BY THE FAA IIC AFTER REMOVAL FROM THE RUNWAY REVEALED WHAT APPEARED TO BE OVERSTRESS FAILURES ON THE LEFT MLG EXTENSION/RETRACTION BELLCRANK ASSEMBLY AND THE GEAR STRUT TRUNNION: THE BELLCRANK ROD END AT THE DOWN-LOCK SUPPORT BRACE WAS BENT INBOARD AND SEPARATED INTO TWO PIECES, A BELLCRANK PIVOT ATTACH POINT BOLT HAD FRACTURED AND SEPARATED FROM THE TOP OF THE MLG TRUNNION, AND THE LOWER PART OF ONE OF THE TRUNNION ATTACHMENT "EARS" WAS PARTIALLY MISSING. UNAIDED VISUAL EXAMINATION OF THE FRACTURE SURFACES REVEALED FEATURES TYPICAL OF AN INSTANTANEOUS (OVERLOAD) FAILURE MODE, INCLUDING A DULL, FIBROUS FRACTURE TEXTURE, SHAPE CHANGE, AND SHEAR LIPS.
