Narrative:
Departed mem on runway 9. Clearance was climb on runway heading 090 degrees to 3000 ft. Then cleared for a right turn to intercept J66. Turned to 125 degrees and programmed the FMS to intercept the leg to woody intersection. Next call from mem center asked if we were going to intercept J66. I replied we were intercepting now. Center radar had us 4 mi south of the airway. Selected raw data, verified position south of airway, and immediately turned northeast to return to airway. Apparent map shift on FMS was not noticed during busy departure. Will make a conscious effort to doublechk all departure radials/airways in the future, instead of waiting for a warning of FMS/map failure.

Title: FLC OF AN LGT FAILED TO INTERCEPT DEP TRACK AS ASSIGNED DUE TO FMS PROGRAM PROB.
Narrative: DEPARTED MEM ON RWY 9. CLRNC WAS CLB ON RWY HDG 090 DEGS TO 3000 FT. THEN CLRED FOR A R TURN TO INTERCEPT J66. TURNED TO 125 DEGS AND PROGRAMMED THE FMS TO INTERCEPT THE LEG TO WOODY INTXN. NEXT CALL FROM MEM CTR ASKED IF WE WERE GOING TO INTERCEPT J66. I REPLIED WE WERE INTERCEPTING NOW. CTR RADAR HAD US 4 MI S OF THE AIRWAY. SELECTED RAW DATA, VERIFIED POS S OF AIRWAY, AND IMMEDIATELY TURNED NE TO RETURN TO AIRWAY. APPARENT MAP SHIFT ON FMS WAS NOT NOTICED DURING BUSY DEP. WILL MAKE A CONSCIOUS EFFORT TO DOUBLECHK ALL DEP RADIALS/AIRWAYS IN THE FUTURE, INSTEAD OF WAITING FOR A WARNING OF FMS/MAP FAILURE.
