Narrative:
My crew was scheduled to conduct a maintenance ferry flight to another airport with a company maintenance facility. Aircraft had an engine that was running excessively hot. On takeoff, captain applied takeoff power. Ailing engine was about to exceed exhaust gas temperature limit (egt) so he retarded power (on ailing engine only) to 1.8 engine pressure ratio (EPR). Approximately 2.08 EPR was normal. Captain stated he was doing this so as not to overtemp engine, but he did take off with lower than normal power on 1 engine. I do not think this was a safety violation since aircraft was empty and would easily takeoff with an engine inoperative. However, it was out of the ordinary.
Original NASA ASRS Text
Title: A B727-200 MAINT FERRY ON TKOF HAS THE CAPT REDUCE PWR ON AN EXHAUST GAS TEMP LIMITED ENG TO AVOID ENG OVERTEMP.
Narrative: MY CREW WAS SCHEDULED TO CONDUCT A MAINT FERRY FLT TO ANOTHER ARPT WITH A COMPANY MAINT FACILITY. ACFT HAD AN ENG THAT WAS RUNNING EXCESSIVELY HOT. ON TKOF, CAPT APPLIED TKOF PWR. AILING ENG WAS ABOUT TO EXCEED EXHAUST GAS TEMP LIMIT (EGT) SO HE RETARDED PWR (ON AILING ENG ONLY) TO 1.8 ENG PRESSURE RATIO (EPR). APPROX 2.08 EPR WAS NORMAL. CAPT STATED HE WAS DOING THIS SO AS NOT TO OVERTEMP ENG, BUT HE DID TAKE OFF WITH LOWER THAN NORMAL PWR ON 1 ENG. I DO NOT THINK THIS WAS A SAFETY VIOLATION SINCE ACFT WAS EMPTY AND WOULD EASILY TKOF WITH AN ENG INOP. HOWEVER, IT WAS OUT OF THE ORDINARY.
