C180 TIPPED UP ON PROP; NOSE AND WINGTIP AFTER THE L BRAKE SEIZED UP DURING LNDG ROLL CAUSING MINOR DAMAGE TO THE ACFT.

Narrative

LNDG AT MALIN; OR; MUNICIPAL ARPT TO THE NW. A 3-POINT LNDG WAS PERFORMED; WITH AIRSPD INDICATING ABOUT 57 MPH. WIND AND WX WAS NOT A FACTOR. AFTER APPROX 175-200 FT OF ROLLOUT; A VERY VIOLENT VIBRATION WAS FELT ON THE L SIDE OF THE ACFT. AFTER A SHORT PERIOD OF TIME THE ACFT PULLED A LITTLE L. R RUDDER AND A SMALL AMOUNT OF BRAKES (R SIDE) WERE APPLIED TO CTR THE ACFT. AS THE ACFT DECELERATED ALMOST TO A STOP ON THE RWY; IT TIPPED UP ON THE NOSE AND ALMOST WENT OVER ON ITS BACK. AFTER THE SUDDEN PROP STOPPAGE; THE ACFT ENDED UP ON ITS NOSE (SPINNER/PROP); R MAIN GEAR; AND R WINGTIP; WITH THE TAIL ABOUT 75 DEGS VERT. RWY MARKS INDICATED THAT THE L BRAKE SEIZED AND STARTED THE CHAIN OF EVENTS. THE VIOLENT VIBRATION WAS ACTUALLY THE L WHEEL JUMPING ON THE GND; AND WHEN IT STOPPED VIBRATING; IT WAS ACTUALLY DIGGING A TRENCH IN THE DIRT. HUMAN PERFORMANCE FACTORS: I FEEL THAT I SOMEWHAT CONTRIBUTED TO THE TIP-UP BY RUDDERING AND BRAKING ON THE R SIDE WHILE TRYING TO CTR THE PLANE ON THE RWY. I HAD NO WAY OF KNOWING THAT THE L SIDE WAS LOCKED UP; AND EVEN WITH THAT KNOWLEDGE; I'M NOT SURE WHAT I WOULD DO DIFFERENTLY. ON INVESTIGATION; ROCKS WERE FOUND IN THE L BRAKE ASSEMBLY.
