## Discrepancy

AT 25,000 FEET DURING CLIMB, THE AIRCRAFT ROLLED RIGHT AND ELAC NR 1 FAULTED.  RESET WAS OK, THREE MINUTES LATER THE AIRCRAFT ROLLED AGAIN WITH FAULT DISPLAY SYSTEM INDICATING ELAC NR 2 MALFUNCTION.  AIRCRAFT RETURNED TO MSP AND LANDED WITHOUT INCIDENT.  REPLACED BOTH SIDE STICK CONTROLLERS AND NR 1 AND NR 2 FLIGHT MANAGEMENT GUIDANCE COMPUTERS AND NR 1 AND NR 2 ELEVATOR AILERON COMPUTERS.  DURING TEST FLIGHT, ALL SYSTEMS CHECKED NORMAL.
