Narrative:
I was landing on runway 32 with a light right crosswind. The landing was very smooth with the right main touching first, followed by the left main. I was holding the nose off when the aircraft, without warning, began to skid left of the centerline. At the same time, the left wing dropped. I kept the aircraft on the runway using a combination of right brake and hydraulic nose steering. The aircraft came to rest at intersection C on the left side of the runway. I inspected the aircraft prior to it being moved off the runway. The left main had rotated 90 degrees. The shock had fully compressed. The scissors collar had failed allowing the tire to rotate perpendicular to the longitudinal axis. The tire did not burst. After completing my before landing checklist, I visually checked the position of the left main as matter of habit. It looked normal.

Title: PLT OF A PA60-600 AEROSTAR HAS LOSS OF ACFT CTL ON LNDG AS ACFT SKIDS TO THE SIDE. THE L MAIN GEAR ROTATED 90 DEGS AND THE SHOCK FULLY COMPRESSED.
Narrative: I WAS LNDG ON RWY 32 WITH A LIGHT R XWIND. THE LNDG WAS VERY SMOOTH WITH THE R MAIN TOUCHING FIRST, FOLLOWED BY THE L MAIN. I WAS HOLDING THE NOSE OFF WHEN THE ACFT, WITHOUT WARNING, BEGAN TO SKID L OF THE CTRLINE. AT THE SAME TIME, THE L WING DROPPED. I KEPT THE ACFT ON THE RWY USING A COMBINATION OF R BRAKE AND HYD NOSE STEERING. THE ACFT CAME TO REST AT INTXN C ON THE L SIDE OF THE RWY. I INSPECTED THE ACFT PRIOR TO IT BEING MOVED OFF THE RWY. THE L MAIN HAD ROTATED 90 DEGS. THE SHOCK HAD FULLY COMPRESSED. THE SCISSORS COLLAR HAD FAILED ALLOWING THE TIRE TO ROTATE PERPENDICULAR TO THE LONGITUDINAL AXIS. THE TIRE DID NOT BURST. AFTER COMPLETING MY BEFORE LNDG CHKLIST, I VISUALLY CHKED THE POS OF THE L MAIN AS MATTER OF HABIT. IT LOOKED NORMAL.
