Synopsis
B777 flight crew reported engine malfunction; return to departure airport; and brakes overheating due to overweight landing.
Narrative
2 man crew ZZZ-ZZZ1; runway XX ZZZZZ. With high winds and storms in the vicinity crew elected to use max EPR (Engine Pressure Ratio); and gusty wind procedures. 1.50 was full EPR; reduced was 1.46. At approx 500 feet; #2 engine EGT (Exhaust Gas Temperature) exceeded limits and display went full red. Capt (PM) manually retarded right throttle; maybe 2 knobs worth and EGT decreased within limits. Auto throttle pushed power back up and EGT again went into red band. Crew [advised ATC] and executed company runway XX procedure. Jet was cleaned up. Auto pilot was engaged and FO took flying and radio duties. Tower gave headings and vectored us in a box pattern at 9000 ft. Capt ran all normal and non normal checklist; briefed FAs; attempted to call company (no answer); ran landing data and set up box for ILS XY. Tower notified that winds and wind shear alerts were in effect and they might be stopping all arrivals. Crew elected to finish set up; checklists and briefs. Asked tower for weather update and was told runway XY winds and no current alerts. Based on the impending weather; crew elected overweight landing; flaps 20 (full power was not going to be available for a GA (Go Around)). No notable events on approach and landing. Crew cleared runway and had jet inspected by fire team and elected to taxi to Gate XX. Brake temp EICAS reported 2 tires 5+ range. Decided to get a tug from 1/2 taxiway to the gate. Flight was debriefed; FAs included. High EGT; over weight landing and brake temp. We were joined by ZZZ Chief Pilot who aided in closing out the required items.Noteworthy events. Approach and tower were excellent. Kept radio communication to a minimum and passed pertinent info. ZZZ Chief Pilot staff was a large help to bringing the event to a conclusion. Crew coming down from adrenaline spike and they advised in a helpful manner.Issues. Prior to blocking in; crew scheduling made multiple phone calls seeking an extension decision. Parking brake not even set; checklists not completed and flight events not finished.
Second reporter narrative
Flt # took off on ZZZ Rwy XX on ZZZZZ Departure. Crew used Max VR with full power for takeoff due to gusty winds and weather north of the airport. Normal takeoff parameters prior to 400 ft on climb out. Approximately 5500 ft MSL right engine on EICAS displayed full red EGT (Exhaust Gas Temperature) indicating temperature exceedance during climb. Captain called exceedance to F/O who was flying pilot. Captain manually reduced right throttle sufficiently to reduce EGT below redline. Captain released throttle to see if this occurrence was only transient. Auto throttles returned throttle to climb EPR (Engine Pressure Ratio) and EGT again registered exceedance. Captain [requested priority handling] to ZZZ tower. F/O executed the company single engine procedure for Rwy XX. F/O selected autopilot and was performing flying and radio duties. Captain began emergency procedures for EGT exceedance. Crew elected to return to ZZZ with a flaps 20 overweight landing (518k lbs). Crew did not shutdown engine as it was controllable and within limits as long as high power settings were not required. Crew notified return to airport intentions to ATC; company dispatch via ACARS (Satcom 2 attempted but was put on hold); F/A; and P/A announcement to passengers. Captain reviewed performance data per AFM Ch7 Performance; non-normal landing distance was well within parameters. Crew reviewed and briefed approach for 2 engine; flaps 20; overweight approach and landing for Rwy XY. Normal landing and rollout was executed by F/O. Emergency personnel on ground inspected aircraft and engines and had not detected damage; leaking fluids; etc. Crew elected taxiing under own power to gate. Brake temps on 2 wheels rose to yellow caution during taxi. Checklist advised minimize taxiing. Crew stopped aircraft and was subsequently towed to gate. No other abnormalities. Crew noted (1) EGT exceedance; (2) overweight landing; and (3) brake temperatures in caution range.
