A TWIN ENG ACR IS SUBJECTED TO THE WAKE TURB OF A PRECEDING; CLBING MD11; 10 MI AHEAD. NO ATC ADVISORY; 2 FLT ATTENDANTS AND SOME PAX INJURED ENRTE TO SFO; CA.

Narrative

IN FLT CRUISE FROM LAX-SFO. FLT LEVEL AT FL240 APPROX 310 KIAS. WE WERE RESTR TO FL240 DUE TO SINGLE PACK OP. TKOF AND CLB TO ALT WERE NORMAL. I HAD JUST TURNED OFF THE FASTEN SEATBELT SIGN AND MADE AN ANNOUNCEMENT. WHEN IN THE VICINITY OF RZS; WITH THE AUTOPLT ON; WE STARTED TO ENCOUNTER A LIGHT BUFFET. THE ACFT NOSE THEN PITCHED UP SLIGHTLY AND ROLLED TO THE L AND THEN PITCHED DOWN. THE CAPT (PF) IMMEDIATELY DISENGAGED THE AUTOPLT; ROLLED WINGS LEVEL; AND STARTED A GRADUAL CLB BACK TO ALT. IT FELT AS IF WE ROLLED ABOUT 45 DEGS AND WE LOST 200-300 FT OF ALT. ONCE THE ACFT WAS BACK IN STABLE FLT; THE CAPT ASKED ATC WHO WAS AHEAD OF US AND HOW WERE THE RIDES? ATC SAID THERE WAS A HVY MD11 ABOUT 10 MI AHEAD WHO HAD CLBED UP THROUGH OUR ALT. AT THIS POINT WE CALLED BACK TO THE FLT ATTENDANTS. THE CHIEF FLT ATTENDANT SAID THE OTHER 2 FLT ATTENDANTS WERE HURT; AND THERE WERE MULTIPLE INJURIES TO PAX. WE GOT AS MUCH INFO FROM THE FLT ATTENDANT AS POSSIBLE AND DECLARED OURSELVES A LIFEGUARD/EMER ACFT WITH ATC. AT THIS POINT WE WERE ABOUT 1/2 WAY TO SFO AND WITH THE CONCURRENCE OF 2 DOCTORS ON BOARD; WHO WERE ASSISTING; WE DECIDED TO CONTINUE ON TO SFO. THE DSCNT AND LNDG WERE UNEVENTFUL. WE WENT TO THE GATE WHERE THE ACFT WAS MET BY PARAMEDICS AND ARPT OFFICIALS. PERFORMANCE CONSIDERATIONS: DUE TO THE FACT THAT 2 OUT OF THE 3 FLT ATTENDANTS WERE HURT; IT WAS HARD TO GET TIMELY COMPLETE INFO IN THE FLT STATION AS TO WHAT WAS HAPPENING IN THE BACK. THIS SLOWED UP THE DECISION MAKING PROGRESS.
