A C210 PLT EXPERIENCED LNDG GEAR COLLAPSE ON LNDG.

Narrative

ON OCT/TUE/01 I WAS FLYING FROM OWENSBORO ARPT TO PADUCAH ARPT. THE WX IN THE VICINITY AND ALONG THE ROUTE OF FLT WAS CALLING FOR SEVERE TSTMS AROUND WEST KENTUCKY; SOUTHERN OHIO; AND SOUTHERN INDIANA. WX CONDITIONS AT PADUCAH WAS 2000 FT SCATTERED; 3500 FT OVERCAST. WIND WAS OUT OF THE SOUTHWEST AT 18 KTS AND GUSTING 26 KTS. IT WAS A 45 MIN FLT. IN THAT FLT I HAD 2 ELECTRIC FAILURES. FIRST WAS FOR 3 MINS AND SECOND WAS FOR 5 MINS. APROX 25 MILES NE OF THE ARPT; MEM CENTER ADVISED ME THAT I WAS NUMBER TWO AND ASSIGNED ME AN ALT OF 2500 FT. WHEN I WAS 5 MI AWAY FROM THE ARPT I RPTED THAT I HAD THE ARPT IN SIGHT; BUT CENTER ASKED ME TO STAND BY AND TOLD ME HE WILL HAND ME TO TWR SHORTLY. WHEN I WAS 2 MI AWAY; I CALLED CENTER TO MAKE SURE HE DIDN'T FORGET ABOUT ME. WHEN CENTER GAVE ME A CLRNC TO CHANGE TO TWR FREQ; I WAS APROX 1.5 MI AWAY FROM THE RWY. AT THAT MOMENT MY RADIO PWR START BLINKING AND I MISSED A RADIO CALL FROM TWR 1 OR 2 TIMES. I HAD THE SAME PROBS A FEW DAYS AGO. FINALLY THE LANDING GEAR ABOUT 1/4 TO 1/2 MI AWAY FROM RWY AND HEARD THE LANDING GEAR PWR PACK GO OFF. HOWEVER IT WAS A REALLY SHORT TIME SO I DIDN'T HAVE A CHANCE TO CHECK FOR A LNDG GEAR GREEN LIGHT. I THOUGHT IT WAS SMOOTH LNDG. I FELT THE LEFT GEAR TOUCH THE GND; AND THEN I NOTICED THAT THE ACFT STARTED TILTING TO THE RIGHT. MY FIRST REACTION WAS TO APPLY LEFT AILERON AND RUDDER TO CORRECT FOR WHAT I THOUGHT WAS DRIFT. AFTER 1 OR 2 SECS; I HEARD A BANGING SOUND WITH BREAKING NOISE FROM ACFT. AT THAT INSTANT; I REALIZED THAT MY RIGHT MAIN GEAR MAY NOT HAVE BEEN DOWN. SO I ADDED FULL PWR TO INITIATE A GAR; BUT BY THAT TIME THE ACFT WAS BADLY DAMAGED. SO I REDUCED THROTTLE TO IDLE AND CUT THE MIXTURE. I TRIED TO STABILIZE THE ACFT AS MUCH AS POSSIBLE. THE ACFT SLID DOWN THE RWY AND CAME TO REST ON THE GRASS NEXT TO THE RWY.
