## Discrepancy

RH ENGINE VIBE 3.9 AT CRUISE. CREW REPORTS AT CRUISE FLIGHT, VIBES REACHED 3.9 AND WAS STILL CLIMBING. CREW SHUT DOWN RH ENGINE IN FLIGHT, BUT RESTARTED TO HAVE TWO GENS. THEY LEFT THE ENGINE AT IDLE AND VIBES WERE AT 1.4. CREW DECLARED EMERGENCY AND RTF. DFW MX REPLACED THE VIBRATION ACCELEROMETER AND PERFORMED FCF. FCF FAILED. AIRCRAFT STILL CURRENTLY OOS IN DFW.
