PLT OF A SMA SEL LOSS CTL OF ACFT DURING LNDG ROLL DUE TO A FLAT MAIN GEAR TIRE.

Narrative

UPON LNDG AT (PSF) PEASE INTL TRADESPORT ON RWY 16; I TOUCHED DOWN WITH MY L MAIN GEAR FIRST; R MAIN GEAR SECOND; AND I THEN HELD THE NOSE WHEEL OFF THE GND (WITH PWR AT IDLE) FOR APPROX 50 FT. ONCE THE NOSE OF THE ACFT TOUCHED THE RWY; I RETRACTED MY FLAPS. AT THIS TIME THE ACFT WAS AT A SPD OF 60 KTS AND SLOWING UNDER ITS OWN WT (I HAD NOT YET APPLIED THE BRAKES). AT THIS TIME I WAS EXPERIENCING A SEVERE YAW TO THE R. APPLYING FULL L RUDDER TO COMPENSATE THE ACFT DID NOT RESPOND. I THEN APPLIED FULL L BRAKE TO DRAG THE L MAIN WHEEL TO WIDEN THE ACFT'S ABRUPT TURN TO THE R (THIS PREVENTED THE ACFT FROM ROLLING ONTO ITS L WING). THE PLANE HAD COMPLETED IT'S TURN OFF OF THE S EDGE OF RWY 16 AND STOPPED; FACING A HDG OF 340 DEGS. AN APPARENT CREASE IN THE INNERTUBE OF THE R TIRE INDUCED A SLIGHT LEAK LEAVING ENOUGH AIR IN THE TIRE TO MAKE A SMOOTH COMFORTABLE LNDG. ONCE I RETRACTED MY FLAPS ALLOWING THE ACFT'S WT TO SETTLE ON THE SPINNING MAIN GEAR WHEELS IT SQUEEZED THE REMAINING AIR OUT OF THE R TIRE (INNER TUBE). THE FLAT R TIRE CAUSED ENOUGH FRICTION/DRAG ON THE RWY TO CAUSE THE ACFT TO YAW TO THE R. BY LOCKING UP THE L WHEEL'S BRAKE ALLOWED ENOUGH FRICTION/DRAG UPON THE RWY TO PREVENT THE ACFT FROM FLIPPING/ROLLING. THERE WERE NO INJURIES TO ANYONE. THE DAMAGE TO THE ACFT WAS THE R MAIN TIRE AND INNER TUBE THAT WERE INTACT ENOUGH TO ALLOW MECHS TO FILL THE TIRE WITH AIR APPROX EVERY 1000 FT; ALLOWING MYSELF TO TAXI THE ACFT ACROSS THE FIELD TO THE MAINT HANGAR WHERE IT COULD BE PROPERLY CHANGED AND THE ACFT COULD BE THOROUGHLY INSPECTED.
