Narrative:
On visual approach into mem on runway 27 (left base), first officer was flying. He notified me that we had no main trim. We were on a left base. We checked circuit breakers (all were in), no trim on captain's side either. Standby trim did work, but even so, my first officer had to exert some force to maintain approach pitch. We were inside FAF by now, fully configured and stabilized. We discussed my landing the aircraft, but since stable and configured, was safest to have first officer complete the landing. We discussed go around, but again were stabilized and configured, so we decided to continue. We landed without incident, cleared runway, taxied to ramp and called our maintenance with main trim inoperative.

Narrative: ON VISUAL APCH INTO MEM ON RWY 27 (L BASE), FO WAS FLYING. HE NOTIFIED ME THAT WE HAD NO MAIN TRIM. WE WERE ON A L BASE. WE CHKED CIRCUIT BREAKERS (ALL WERE IN), NO TRIM ON CAPT'S SIDE EITHER. STANDBY TRIM DID WORK, BUT EVEN SO, MY FO HAD TO EXERT SOME FORCE TO MAINTAIN APCH PITCH. WE WERE INSIDE FAF BY NOW, FULLY CONFIGURED AND STABILIZED. WE DISCUSSED MY LNDG THE ACFT, BUT SINCE STABLE AND CONFIGURED, WAS SAFEST TO HAVE FO COMPLETE THE LNDG. WE DISCUSSED GAR, BUT AGAIN WERE STABILIZED AND CONFIGURED, SO WE DECIDED TO CONTINUE. WE LANDED WITHOUT INCIDENT, CLRED RWY, TAXIED TO RAMP AND CALLED OUR MAINT WITH MAIN TRIM INOP.
