WAKE TURB ENCOUNTER SHORTLY AFTER TKOF.

Narrative

DURING THE INITIAL TURN TO ON COURSE WE ENCOUNTERED WAKE TURB OF ANOTHER DEPARTING ACFT. NORMALLY ON TKOF RWY 28R WE ARE GIVEN A 360 DEG HDG AND THEN DIRECT EWC. BUT WITH THIS CLR WX WE WERE GIVEN DIRECT SLT WHICH WAS ABOUT A 060 DEG HDG. AT ABOUT 500-700 FT AGL WE ENCOUNTERED A STRONG WAKE TURB WHICH CAUSED A STRONG ROLLING MOTION TO THE OUTSIDE OF THE TURN AND ABOUT A 40 DEG ROLL (L). BEFORE WE COULD COMPLAIN TO ATC WE HEARD OUR COMPANY COMPLAIN ABOUT ENCOUNTERING WAKE TURB FROM THE ACFT IN FRONT OF HIM! WE ALSO LET ATC KNOW ABOUT OUR ENCOUNTER. THIS WAS A VERY CLR; STILL NIGHT AND WE WERE IN A BIG PUSH OUT OF PIT (LAST OF THE NIGHT) AND ATC WAS JUST SLINGING US OUT AND GETTING US ON OUR WAY. WHEN ATC HEARD OUR COMPLAINTS THEY APOLOGIZED AND SAID THEY WOULDN'T KEEP US SO CLOSE NEXT TIME. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: RPTR PARTICIPATED IN THE WAKE TURB STRUCTURED CALLBACK. RPTR WAS SURPRISED AT THE ENCOUNTER AS THERE WAS NO WARNING TO HIS ACFT APCHING ANY TURB. AS HE REFLECTED ON THE ENVIRONMENT OF THAT EVENING; THE AIR WAS STILL AND VISIBILITY VERY GOOD. ANOTHER ACFT AHEAD OF HIM COMPLAINED OF WAKE TURB DURING HIS CLBOUT; BUT HE HAD NO KNOWLEDGE OF THE LOCATION OF THE TURB. THESE 2 FACTS SHOULD HAVE ALERTED HIM THAT HE MIGHT ENCOUNTER SOME TURB AS ALL DEPS WERE TAKING OFF W WITH AN IMMEDIATE R TURN TO THE E. THE DEPS HAD CLOSE GND TRACKS. WHEN HE ENCOUNTERED THE TURB IT ROLLED HIM FROM A R BANK TO A L BANK; A TOTAL OF 40 DEGS CHANGE. HE PUT CTL INPUTS IN TO OPPOSE THE EFFECT OF THE TURB BUT IT STILL ROLLED HIM THE OPPOSITE WAY. ALTHOUGH THE TURB EFFECT ONLY LASTED 5-6 SECONDS; HE WAS BOTHERED BY THE FACT THAT THE ACFT WAS ROLLING AGAINST HIS CTL INPUTS. FULL CTL RESUMED IMMEDIATELY AFTER THE ENCOUNTER AND EVERYTHING ELSE CONTINUED NORMALLY.
