## Discrepancy

ON GEAR RETRACTION RED GEAR LIGHTS A AND B REMAINED ON AND LT MAIN GEAR DOOR WOULD NOT SHUT.  MAINTENANCE INVESTIGATION REVELED THAT THE PN 19659 BUSHINGS IN BOTH THE LT AND RT UP-LOCK HOOK SUPPORT ASSY.  PN 19552 WERE AT MINIMUM OVERHAUL TOLERANCES.  IN COLD TEMPERATURES (-35F TO -40F) THESE CLEARANCES WERE TOO TIGHT.  BUSHINGS WERE REAMED TO THE UPPER O/H CLEARANCE LIMITS.  ASSY REASSEMBLED AND OPERATIONALY CHECKED.  AC RETURNED TO SERVICE WITH NO ADDITIONAL PROBLEMS.  (K)
