What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
Pilot stated that after a normal touchdown, the airplane started to slowly drift to the right.
The pilot then corrected with differential braking while also braking to reduce speed. The plane then started tracking slightly left. To keep the plane centered the pilot applied left and right braking. On reduction of left brake, the left main landing gear collapsed. The left-wing tip, aileron, and flap contacted the runway while the aircraft traveled gradually to the right and off of the runway. The right main landing gear striked a runway edge marking light and collapsed the right main landing gear. The aircraft came to a rest in a nose high attitude with the engine at idle. It setted in the grass near the edge of the runway. According to the pilot, upon the post incident examination of the left main landing gear, it indicates that the side brace stud on the gear leg partially separated from the gear leg at the weld.
As the FAA filed it
PILOT STATED THAT AFTER A NORMAL TOUCHDOWN, THE AIRPLANE STARTED TO SLOWLY DRIFT TO THE RIGHT.
THE PILOT THEN CORRECTED WITH DIFFERENTIAL BRAKING WHILE ALSO BRAKING TO REDUCE SPEED. THE PLANE THEN STARTED TRACKING SLIGHTLY LEFT. TO KEEP THE PLANE CENTERED THE PILOT APPLIED LEFT AND RIGHT BRAKING. ON REDUCTION OF LEFT BRAKE, THE LEFT MAIN LANDING GEAR COLLAPSED. THE LEFT-WING TIP, AILERON, AND FLAP CONTACTED THE RUNWAY WHILE THE AIRCRAFT TRAVELED GRADUALLY TO THE RIGHT AND OFF OF THE RUNWAY. THE RIGHT MAIN LANDING GEAR STRIKED A RUNWAY EDGE MARKING LIGHT AND COLLAPSED THE RIGHT MAIN LANDING GEAR. THE AIRCRAFT CAME TO A REST IN A NOSE HIGH ATTITUDE WITH THE ENGINE AT IDLE. IT SETTED IN THE GRASS NEAR THE EDGE OF THE RUNWAY. ACCORDING TO THE PILOT, UPON THE POST INCIDENT EXAMINATION OF THE LEFT MAIN LANDING GEAR, IT INDICATES THAT THE SIDE BRACE STUD ON THE GEAR LEG PARTIALLY SEPARATED FROM THE GEAR LEG AT THE WELD.
