## Discrepancy

(CAN) DURING FLIGHT, THE ENGINE POWER ROLLED BACK UNCOMMANDED, AN ALTITUDE CHANGE FROM FL380 TO FL360 CORRECTED THE PROBLEM.  SOON AFTER, ENGINE ROLLED BACK AGAIN, BUT TO A LESSER DEGREE AND RECOVERED.  TROUBLESHOOTING IS FOCUSING ON THE FUEL CONTROL WHICH WILL BE REPLACED. MFG RECOMMENDS THE SDR BE CLOSED ON THE BASIS OF THE FOLLOWING INFORMATION.
