## Discrepancy

NR 2 ENG FAULT HISTORY SHOWS MAINTENANCE MSG MORE THAN ONCE IN 5 LEGS.  NR 1 BEARING ACCELEROMETER SIGNAL OUT OF RANGE. 
WITH THIS MSG OCCURING IN DESCENT, IT IS A NUISANCE, NO ACTION  IS REQUIRED.  ALSO, 483-0058 NR 1 BRG ACCELEROMETER IS AN INTERNAL ENGINE PART.  NOT LRU.  OK FOR SERVICE PER MT77-005.
