## Discrepancy

DURING PHASE INSPECTIONS, BOTH LT AND RT ELEVATOR TRIM ACTUATORS WERE FOUND OUT OF FREE-PLAY LIMITS PER BEECH E90 MM.  ACQUIRED 2 NEW ACTUATORS.  BOTH INSTALLED WITH ALL NEW BUSHINGS AND BOLTS IN SYSTEM.  AFTER FINAL RIGGING, ANOTHER FREE-PLAY CHECK WAS MADE.  THE RT ACTUATOR WAS IN LIMITS BY .001 INCH, LT OUT OF LIMITS BY .009 INCH.  ANOTHER OVERHAULED LT ACTUATOR WAS ACQUIRED AND INSTALLED.  FINAL FREE-PLAY CHECK SHOWED IT TOO WAS OUT OF LIMITS.  ALL 3 ACTUATORS OVERHAULED BY SAME FACILITY.  ANOTHER SET OF LT AND RT ACTUATORS WERE FOUND, BUT SENT BACK TO O/H FACILITY TO BE RE-CHECKED FOR PROPER O/H LIMITS.  SUBMITTER RECOMMENDED ALL BEECH E90 ELEVATOR TRIM ACTUATOR CHANGES HAVE A FINAL FREE-PLAY CHECK MADE.
