Narrative:

Final approach runway 23 at bct, wind was 190 degrees at 10 KTS, was on stabilized approach, with the correct crosswind corrections input. Once the mains came down, I lowered the nose gear and began to apply brake pressure to slow down and exit the runway, while keeping the crosswind correction in. Suddenly the right wing of the aircraft lifted up, causing the aircraft to veer off to the left. When this happened, the aircraft went completely off the runway for a short time then I was able to bring the aircraft back onto the runway. I firmly believe that it was windshear that caused the aircraft to be blown off the runway in the opposite direction of the crosswind.

Title: C172 PVT PLT LOST CTL OF THE ACFT DURING LNDG RESULTING IN THE ACFT GOING OFF THE SIDE OF THE RWY. RPTR REGAINED CTL AND BROUGHT ACFT BACK TO THE RWY.

Narrative: FINAL APCH RWY 23 AT BCT, WIND WAS 190 DEGS AT 10 KTS, WAS ON STABILIZED APCH, WITH THE CORRECT XWIND CORRECTIONS INPUT. ONCE THE MAINS CAME DOWN, I LOWERED THE NOSE GEAR AND BEGAN TO APPLY BRAKE PRESSURE TO SLOW DOWN AND EXIT THE RWY, WHILE KEEPING THE XWIND CORRECTION IN. SUDDENLY THE R WING OF THE ACFT LIFTED UP, CAUSING THE ACFT TO VEER OFF TO THE L. WHEN THIS HAPPENED, THE ACFT WENT COMPLETELY OFF THE RWY FOR A SHORT TIME THEN I WAS ABLE TO BRING THE ACFT BACK ONTO THE RWY. I FIRMLY BELIEVE THAT IT WAS WINDSHEAR THAT CAUSED THE ACFT TO BE BLOWN OFF THE RWY IN THE OPPOSITE DIRECTION OF THE XWIND.
