## Discrepancy

ELEVATOR WAS VERY STIFF, BOTH NOSE DOWN & NOSE UP, ON THE GND & IN THE AIR.  IT SEEMED TWICE THE NORMAL ELEVATOR PRESS WAS REQUIRED, BOTH IN FLIGHT & ON GND.  R & R ELEVATOR LOAD FEEL DUPLEX ACTUATOR, CLEANED & LUBED ELEVATOR ACTUATORS & TENSION REGULATORS.  TESTED PUSH PULL LIMITS & FOUND TO BE ON THE HIGH SIDE, BUT STILL WITHIN LIMITS IAW AMM 27-32-01-4, 12-24-04-3-0 & 27-30-00-5.  OK FOR SERVICE.
