## Discrepancy

AIRCRAFT WAS GROUNDED: AN EMERGENCY WAS DECLARED AND THE AIRCRAFT RETURNED TO LAX DUE TO THE FLIGHT CREW REPORTING THAT DURING CLIMB OUT WHILE PASSING 10000 FEET, #2 ENGINE INDICATED HIGH ENGINE VIBRATION OF N1 8.0-9.0 INTERMITTENTLY AND THEN STAYED CONSTANT FOR 15-20 MINUTES. THE FLIGHT CREW REPORTED THAT CABIN VIBRATIONS WERE FELT IN THE FORWARD AND AFT CABIN MEASURING 5 OUT OF 10. THE AIRCRAFT LANDED SAFLEY AT LAX WITHOUT FURTHER INCIDENT.  MAINTENANCE REPLACED #2 ACCELEROMETER AND ACCOMPLISHED A SATISACTORY OPS CHECKED WITH NO ISSUES NOTED.
