## Discrepancy

ON TAKEOFF, IT TOOK A NOTICABLE AMOUNT OF BACK PRESSURE TO LIFT ACFT OFF RUNWAY. TRIM WAS SET TO 7.0. FLT CONTINUED WITH AUTOPILOT WITH NOTHING NOTICEABLE UNTIL LANDING. WHEN DISCONNECTING A/P AT 500',  TRIM 7.2 IN THE FLARE AT 100', ELEVATOR CONTROL WAS LOST. WAS UNABLE TO FLY ACFT TO RUNWAY.  R & R ELEVATOR PCU SHEAR PINS IAW SB 601R-55-008. OPS CHECK GOOD, NO FURTHER DEFECTS NOTED AT THIS TIME.  ACFT RETURNED TO SERVICE.
