Narrative:
I encountered a windshear on approach to landing that caused loss of control to aircraft. I had to use extreme hard right rudder on full power to prevent a stall and spin at 100 ft AGL on final. The wind had been from 10-20 KTS with gusty conditions for the previous 3 hours. Those conditions resulted in 4 changes in runway direction during that time frame. I managed to regain control and land on the main gear as a normal landing. On rollout I felt a 'tugging' on the aircraft. When it slowed down to 5-10 KTS, the plane stopped and rolled over on its propeller and spinner. After I got out of the plane I found the brakes were locked. I have heard of other C170's having similar brake problems since this incident.

Title: PLT OF A C170B LOST CTL OF THE ACFT DURING APCH TO LNDG, REGAINED CTL AND LOST IT AGAIN DURING ROLLOUT DUE TO STUCK BRAKES. THE ACFT ABRUPTLY SLOWED AND FLIPPED OVER ONTO THE PROP AND SPINNER.
Narrative: I ENCOUNTERED A WINDSHEAR ON APCH TO LNDG THAT CAUSED LOSS OF CTL TO ACFT. I HAD TO USE EXTREME HARD R RUDDER ON FULL PWR TO PREVENT A STALL AND SPIN AT 100 FT AGL ON FINAL. THE WIND HAD BEEN FROM 10-20 KTS WITH GUSTY CONDITIONS FOR THE PREVIOUS 3 HRS. THOSE CONDITIONS RESULTED IN 4 CHANGES IN RWY DIRECTION DURING THAT TIME FRAME. I MANAGED TO REGAIN CTL AND LAND ON THE MAIN GEAR AS A NORMAL LNDG. ON ROLLOUT I FELT A 'TUGGING' ON THE ACFT. WHEN IT SLOWED DOWN TO 5-10 KTS, THE PLANE STOPPED AND ROLLED OVER ON ITS PROP AND SPINNER. AFTER I GOT OUT OF THE PLANE I FOUND THE BRAKES WERE LOCKED. I HAVE HEARD OF OTHER C170'S HAVING SIMILAR BRAKE PROBS SINCE THIS INCIDENT.
