SMA LOSES ACFT CTL ON TOUCHDOWN AND GOES OFF RWY EDGE.

Narrative

AIRPLANE HAD BEEN IN SHOP FOR 2 1/2 MONTHS FOR REFURBISHING IMMEDIATELY PRIOR TO EVENT. FLT WAS FIRST LONG XCOUNTRY SINCE RETURN TO SVC. AFTER FLT TO SYI; CHKED WX FOR RETURN TO ROA. FORECAST FOR ROA INCLUDED WIND FROM NW AT 11 KTS. UPON APCH TO ROA (AFTER 5.9 HR TOTAL IFR FLT ON BOTH LEGS); ATIS CALLED FOR WIND OF 300 DEG AT 12 KTS. APCH WAS IN MODERATE TURB. ON VISUAL TO 33; CLRED TO LAND WITH A COMMUTER #2 CLOSE BEHIND ME. TWR RPTED WIND OF 290 DEG AT 14 KTS. IN VIEW OF WIND; SELECTED APCH FLAPS ONLY AND HIGHER MANIFOLD PRESSURE (FASTER) THAN NORMAL. JUST AS I WAS FLARING; WHEN THE THROTTLE WOULD NORMALLY BE CLOSED; THE TWR DECLARED: 'THIS WON'T WORK; GAR...' I TOUCHED DOWN BOTH MAINS WITH THE THROTTLE STILL OPEN; MOMENTARILY CONFUSED BY THE TWR'S INSTRUCTION BEFORE I REALIZED IT WAS FOR THE COMMUTER BEHIND ME. AT THAT POINT; HAVING BEEN BLOWN SOMEWHAT R OF CTRLINE; THE NOSE WHEEL TOUCHED (NOSE WHEEL STEERING) AND THE PLANE VEERED SHARPLY L. AS I APCHED THE L EDGE OF THE RWY; I REGAINED CTL OF THE STEERING AT A 45 DEG ANGLE TO CTRLINE. RATHER THAN ATTEMPTING A HARD R TURN AND RISKING COLLAPSING THE GEAR; I CONTINUED OFF THE L EDGE OF THE RWY INTO SHORT GRASS. AFTER A BRIEF CONVERSATION WITH THE TWR; I WAS CLRED TO CROSS THE RWY AND TAXI TO THE RAMP. FORTUNATELY NO DAMAGE WAS DONE TO THE PLANE OR ANY OTHER PROPERTY. I PROBABLY OVER- CORRECTED UPON INITIAL TOUCHDOWN RESULTING IN THE INITIAL LOSS OF CTL. REVIEWING MY LOGBOOK AFTER THE EVENT; I NOTICED THAT I WAS CLOSE TO GOING OUT OF CURRENCY (IFR) DUE TO THE LONG STAY OF THE PLANE IN THE SHOP; THOUGH I HAD HAD SEVERAL RECENT STRONG XWIND LNDGS. OBVIOUSLY; WE CANNOT PRACTICE ENOUGH! HAD I NOT BEEN DISTRACTED AND HAD I FULLY CLOSED THE THROTTLE; I PROBABLY WOULD NOT HAVE GONE OFF THE RWY. MY NEXT FLT WILL BE WITH A CFII TO REVIEW MY LNDG TECHNIQUE AND RESTORE CURRENCY AND CONFIDENCE.
