Narrative:

I was completing a flight from ocf to ZZZ. The flight was normal and unremarkable from takeoff to touchdown. I monitored the ZZZ AWOS and heard that winds were primary from 170 degrees at 6 KTS with at least 1 report of wind from 160 degrees and one from 180 degrees. The landing approach was normal. Touchdown was within the first 1000 ft; smooth and just slightly right of the centerline. The rollout after touchdown initially felt normal but after a few seconds and somewhere around 500-800 ft; it felt like the airplane was beginning to be pulled to the left. I started putting in right rudder to keep the airplane straight. I thought the plane was going to stay straight but it pulled harder and harder to the left. I thought the left main tire was flat. I put in more and more right rudder to try and straighten it up. The plane was now skidding with the nose going left and the tail coming around on the right. The plane spun around 180 degrees as it went off the left (east) side of the runway. The right main collapsed and the right wing and stabilizer/evaluator stuck the ground as we went off the runway. I used the radio to alert other aircraft; shut down the engine (thankfully no propeller strike); turned off the magnetos; and got out. The airport manager contacted the police; FAA; and NTSB. There were no injuries and upon initial inspection does not appear to be any structural damage. At this point I do not know what caused the airplane to pull and turn left. The sensation was as if something was causing drag on the left side such as the left brake being applied or that tire going flat. The plane has hand brakes and I had not used any brake before or during the incident.

Title: LOW TIME PRIVATE PLT OF PA24 LOSES CONTROL ON LANDING. ACFT EXITS LEFT SIDE OF RWY COLLAPSING THE RIGHT MAIN GEAR.

Narrative: I WAS COMPLETING A FLT FROM OCF TO ZZZ. THE FLT WAS NORMAL AND UNREMARKABLE FROM TKOF TO TOUCHDOWN. I MONITORED THE ZZZ AWOS AND HEARD THAT WINDS WERE PRIMARY FROM 170 DEGS AT 6 KTS WITH AT LEAST 1 RPT OF WIND FROM 160 DEGS AND ONE FROM 180 DEGS. THE LNDG APCH WAS NORMAL. TOUCHDOWN WAS WITHIN THE FIRST 1000 FT; SMOOTH AND JUST SLIGHTLY R OF THE CTRLINE. THE ROLLOUT AFTER TOUCHDOWN INITIALLY FELT NORMAL BUT AFTER A FEW SECONDS AND SOMEWHERE AROUND 500-800 FT; IT FELT LIKE THE AIRPLANE WAS BEGINNING TO BE PULLED TO THE L. I STARTED PUTTING IN R RUDDER TO KEEP THE AIRPLANE STRAIGHT. I THOUGHT THE PLANE WAS GOING TO STAY STRAIGHT BUT IT PULLED HARDER AND HARDER TO THE L. I THOUGHT THE L MAIN TIRE WAS FLAT. I PUT IN MORE AND MORE R RUDDER TO TRY AND STRAIGHTEN IT UP. THE PLANE WAS NOW SKIDDING WITH THE NOSE GOING L AND THE TAIL COMING AROUND ON THE R. THE PLANE SPUN AROUND 180 DEGS AS IT WENT OFF THE L (E) SIDE OF THE RWY. THE R MAIN COLLAPSED AND THE R WING AND STABILIZER/EVALUATOR STUCK THE GND AS WE WENT OFF THE RWY. I USED THE RADIO TO ALERT OTHER ACFT; SHUT DOWN THE ENG (THANKFULLY NO PROP STRIKE); TURNED OFF THE MAGNETOS; AND GOT OUT. THE ARPT MGR CONTACTED THE POLICE; FAA; AND NTSB. THERE WERE NO INJURIES AND UPON INITIAL INSPECTION DOES NOT APPEAR TO BE ANY STRUCTURAL DAMAGE. AT THIS POINT I DO NOT KNOW WHAT CAUSED THE AIRPLANE TO PULL AND TURN L. THE SENSATION WAS AS IF SOMETHING WAS CAUSING DRAG ON THE L SIDE SUCH AS THE L BRAKE BEING APPLIED OR THAT TIRE GOING FLAT. THE PLANE HAS HAND BRAKES AND I HAD NOT USED ANY BRAKE BEFORE OR DURING THE INCIDENT.
