## Discrepancy

DURING CLIMB, AFTER FLAPS RETRACTION A/C DID NOT ACCELERATE MORE THAN 235 KNOTS.  BOTH PFDS AND STANDBY AIRSPEED SHOWED THE SAME MESSAGE.  AIRCRAFT RETURNED TO SAL FOR MAINTENANCE.  AFTER LANDNG, THE WIRING ON THE VMO/MMO SWITCH WAS CHECKED AND TROUBLESHOOTING WAS PERFORMED PER TASK TSM 34-13-00-810-912, AND NR LGCIU WAS REPLACED DUE TO ERRONEOUS FAULT PER AMM 32-31-71.  NO FAULTS WERE NOTED.  A FLIGHT TEST WAS PERFORMED TO VERIFIED ALL SYSTEMS AND ITS RESULTS WERE SATISFACTORY.  AIRCRAFT RETURNED TO NORMAL OPERATION.  (M)
