## Discrepancy

CREW REPORTED THAT DURING CLIMBOUT A VIBRATION AND LOW RUMBLE COULD BE HEARD AND FELT.  AFTER LEVELING OFF, THE AIRCRAFT WOULD NOT ACCELERATE PAST 0.70 MACH IN CLIMB MODE.  THE AIRCRAFT DIVERTED TO SDF AND LANDED WITHOUT INCIDENT.  MAINTENANCE REPLACED THE NOSE LANDING GEAR DOOR SOLENOID AND FLAP ELECTRONIC CONTROL UNIT AND GEAR RETRACTION TESTS CHECKED GOOD.
