Narrative:
Takeoff was in rain with outside air temperature 7 degrees C, engine bleeds and packs on, engine anti-ice on. Upon gear retraction right engine compressor stalled and egt exceeded limit (maximum egt reached was 695 degrees). ATC was notified of engine failure and that company emergency takeoff procedure was being followed. Returned to field for overweight landing (12000 ft runway). I think compressor stall was induced by gear retraction (gear on center hydraulic system which is pressurized by air demand pump). Power was reduced and engine operated normally afterward. Comments regarding ATC: in a high workload situation ATC communication is a distraction. ATC should know that we have an emergency takeoff procedure for terrain avoidance and should leave us alone until we ask for help. Callback conversation with reporter revealed the following information: the reporter stated the aircraft was a B767-300 powered with P&west JT9D-7r4 engines. The reporter said the exact cause of the engine failure was unknown as maintenance has not reported their findings.
Original NASA ASRS Text
Title: A B767-300 ON TKOF AT 50 FT DECLARED AN EMER AND DIVERTED DUE TO A #2 ENG COMPRESSOR STALL AND EXHAUST GAS TEMP LIMIT EXCEEDED RESULTING IN THE ENG BEING SHUT DOWN.
Narrative: TKOF WAS IN RAIN WITH OUTSIDE AIR TEMP 7 DEGS C, ENG BLEEDS AND PACKS ON, ENG ANTI-ICE ON. UPON GEAR RETRACTION R ENG COMPRESSOR STALLED AND EGT EXCEEDED LIMIT (MAX EGT REACHED WAS 695 DEGS). ATC WAS NOTIFIED OF ENG FAILURE AND THAT COMPANY EMER TKOF PROC WAS BEING FOLLOWED. RETURNED TO FIELD FOR OVERWT LNDG (12000 FT RWY). I THINK COMPRESSOR STALL WAS INDUCED BY GEAR RETRACTION (GEAR ON CTR HYD SYS WHICH IS PRESSURIZED BY AIR DEMAND PUMP). PWR WAS REDUCED AND ENG OPERATED NORMALLY AFTERWARD. COMMENTS REGARDING ATC: IN A HIGH WORKLOAD SIT ATC COM IS A DISTR. ATC SHOULD KNOW THAT WE HAVE AN EMER TKOF PROC FOR TERRAIN AVOIDANCE AND SHOULD LEAVE US ALONE UNTIL WE ASK FOR HELP. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE RPTR STATED THE ACFT WAS A B767-300 POWERED WITH P&W JT9D-7R4 ENGS. THE RPTR SAID THE EXACT CAUSE OF THE ENG FAILURE WAS UNKNOWN AS MAINT HAS NOT RPTED THEIR FINDINGS.
