## Discrepancy

(CAN) THE CREW REPORTED AN UNCOMMANDED POWER LOSS ON THE NR 2 ENGINE OF APPROXIMATELY 30 PERCENT TORQUE.  THERE WERE NO INDICATIONS TO EXPLAIN THE POWER LOSS.  LIGHTS WERE TESTED, FAULT CHECK LISTS CARRIED OUT WITH NOTHING FOUND. THE POWER MANAGEMENT SELECTOR WAS RECYCLED AND THE ENGINE SLOWLY RECOVERED POWER. THE FLIGHT CONTINUED TO DESTINATION WHERE IT LANDED SAFELY.  TROUBLESHOOTING IS ON-GOING.
