AN ACR MD-88 GOT WAKE TURB BEHIND AN ACR B-767.

Narrative

ON DSCNT INTO ATL FROM SE; ABOUT 30 MI OUT; THE RWY/APCH WAS AN ILS 8L. APCH SLOWED US TO 160 KTS AND SEQUENCED US IN BEHIND A HVY B767 (ABOUT 5 MI INTRAIL). AT ABOUT 8 MI OUT (FROM RWY) WE WERE BOTH SLOWED TO 150 KTS. SHORTLY THEREAFTER WE STARTED TO ENCOUNTER THE 767'S WAKE TURB. AT CATTA WE WERE TOLD TO DISCONTINUE THE APCH AND TOLD TO TURN TO 360 DEGS AND CLB TO 4000 FT. WE ACCOMPLISHED AN UNEVENTFUL GAR AND WERE SUBSEQUENTLY CLRED FOR AN UNEVENTFUL ILS TO RWY 8L. APCH WAS TRYING TO SEQUENCE TOO MANY ACFT INTO THE APCH STREAM AT THE SAME TIME. SUPPLEMENTAL INFO FROM ACN 263458: WE WERE POSITIONED 5 MI BEHIND A HVY 767 AT 160 KIAS. WE WERE AT 160 KIAS AS WELL. WE WERE CLRED FOR THE APCH AT 5000 FT MSL; 5 MI BEHIND THE HVY. APCH THEN TOLD THE HVY TO SLOW 10 KIAS TO 150 KIAS AND WE ALSO SLOWED TO 150 KIAS. OUR SPACING BEGAN TO DETERIORATE TO AROUND 3 MI. AT THAT TIME WE BEGAN FEELING THE HVY'S WAKE TURB. AT CATTA THE TWR DECIDED THAT SPACING WAS INSUFFICIENT AND ORDERED US TO CUT OFF THE APCH AND TURN L TO 360 DEGS AND CLB TO 4000 FT MSL. I BELIEVE THAT APCH HAD TRIED TO SQUEEZE US IN TOO CLOSELY. THERE WAS NO MARGIN FOR DIFFERENT AIRSPDS BTWN US AND THE 767.
