Narrative:

During climb through FL380, the right engine egt rose to 810 degrees C. The right throttle was reduced to keep egt within limits. Other engine parameters suggested that the engine was not capable of producing significant power without exceeding egt limits. The right engine was operated at reduced power settings as an uneventful return to sea ensued.

Title: HIGH ENG EGT DURING CLB RESULTS IN A RETURN TO DEP STATION WITH REDUCED THRUST.

Narrative: DURING CLB THROUGH FL380, THE R ENG EGT ROSE TO 810 DEGS C. THE R THROTTLE WAS REDUCED TO KEEP EGT WITHIN LIMITS. OTHER ENG PARAMETERS SUGGESTED THAT THE ENG WAS NOT CAPABLE OF PRODUCING SIGNIFICANT PWR WITHOUT EXCEEDING EGT LIMITS. THE R ENG WAS OPERATED AT REDUCED PWR SETTINGS AS AN UNEVENTFUL RETURN TO SEA ENSUED.
