AT 800 FT; DEPARTING PHX 40 SECONDS BEHIND A B737-700; A B767 HAS A L ENG COMPRESSOR STALL FOLLOWED 8 SECONDS LATER BY A STALL IN THE R ENG.

Narrative

AFTER TKOF FROM PHX; AT APPROX 800 FT AGL; THE #1 ENG HAD A COMPRESSOR STALL. (WE FIRST THOUGHT WE HAD BLOWN A TIRE IN THE WHEEL WELL DUE TO LONG TAXI OR WE HAD COLLIDED WITH SOMETHING OR LOST AN ENG.) THEN 8 SECONDS LATER THE R ENG HAD A COMPRESSOR STALL. WE CONTINUED OUR CLBOUT AND CLEANED THE ACFT UP. I CALLED THE FIRST FLT ATTENDANT. HE CONFIRMED THEY HEARD THE 'BOOM' AND RPTED THAT PAX SAW FLAMES COME FROM THE L; THEN R ENG. WE CHKED THE ENG INSTS -- EVERYTHING WAS NORMAL. WE CONTINUED OUR CLB TO FL280. I CONTACTED COMPANY VIA COMRDO AND TALKED TO MAINT CTL. MAINT CTL CONFIRMED THAT WE HAD EXPERIENCED 2 COMPRESSOR STALLS; 1 L AND 1 R. WE WERE TOLD TO LAND AT THE NEAREST SUITABLE ARPT. WE CHOSE LAX. I TOLD ATC I WANTED A LOW FLY-BY TO ASCERTAIN THAT THERE WAS NO DAMAGE TO THE LNDG GEAR. WE MADE A NORMAL BUT DELICATE OVERWT LNDG. THE EMER EQUIP WAS STANDING BY. AFTER CLRING ALL RWYS; WE PAUSED TO ALLOW A VISUAL INSPECTION OF THE ACFT FOR FLUID LEAKS; THEN PROCEEDED TO THE GATE.CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE RPTR STATED THE TKOF WAS MADE 40 SECONDS BEHIND A B737-700 WITH WINGLETS. DURING INVESTIGATION OF THE INCIDENT IT WAS DETERMINED THAT THERE WA AN 11 PERCENT REDUCTION IN POWER ON THE L ENG AND A GREATER AMOUNT ON THE R. THE ASSUMPTION WAS THAT THERE MAY HAVE BEEN WAKE TURB FROM THE PRECEDING ACFT CAUSING AN INTERRUPTION IN AIRFLOW TO THE ENGS. THE CREW NOTICED TURB TO BE LIGHT AT THE MOST. THE RPTR NOTED THAT THE RECORDED POWER LOSS WAS ALSO AT ABOUT THE SAME TIME A NORMAL POWER REDUCTION WOULD BE MADE FOR THE PHASE OF FLT. THR RPTR STATED THE ACFT WAS BEING OPERATED IN VNAV.
