Narrative:
Climbing through 17000 ft, #1 engine power began to decrease. It continued until full throttle would only yield approximately 80% N1, fuel flow indication was approximately 2000 pounds higher than #2 engine, all other engine indications were normal. Troubleshooting and checklist procedures failed to solve the problem and a decision to return to cle was made. At approximately 10000 ft the engine began to make full power, however, response time was extremely slow and fuel flow indication was significantly higher than #2 engine. An uneventful landing was accomplished in cle.

Title: ACR MLG FLC DECLARED AN EMER DUE TO PARTIAL PWR LOSS ON #1 ENG AND RETURN LAND.
Narrative: CLBING THROUGH 17000 FT, #1 ENGINE POWER BEGAN TO DECREASE. IT CONTINUED UNTIL FULL THROTTLE WOULD ONLY YIELD APPROX 80% N1, FUEL FLOW INDICATION WAS APPROX 2000 LBS HIGHER THAN #2 ENG, ALL OTHER ENG INDICATIONS WERE NORMAL. TROUBLESHOOTING AND CHKLIST PROCS FAILED TO SOLVE THE PROB AND A DECISION TO RETURN TO CLE WAS MADE. AT APPROX 10000 FT THE ENG BEGAN TO MAKE FULL PWR, HOWEVER, RESPONSE TIME WAS EXTREMELY SLOW AND FUEL FLOW INDICATION WAS SIGNIFICANTLY HIGHER THAN #2 ENG. AN UNEVENTFUL LNDG WAS ACCOMPLISHED IN CLE.
