Narrative:

First officer flying manually on approach ILS runway 26R atl. I called localizer capture, first officer called for gear and flaps since we were vectored in high. I was busy configuring. Then checked the FMA and noted it had dropped out of the ILS mode to heading and altitude hold. I told the first officer to immediately turn right and he complied. I looked outside for conflicting traffic on ILS runway 27L in atl. There I saw a B767 abeam and below us. About that time approach called and told us to turn to 300 degree heading to reintercept the localizer and maintain 4000 ft MSL. We recaptured the localizer and GS for an uneventful landing.

Narrative: FO FLYING MANUALLY ON APCH ILS RWY 26R ATL. I CALLED LOC CAPTURE, FO CALLED FOR GEAR AND FLAPS SINCE WE WERE VECTORED IN HIGH. I WAS BUSY CONFIGURING. THEN CHKED THE FMA AND NOTED IT HAD DROPPED OUT OF THE ILS MODE TO HDG AND ALT HOLD. I TOLD THE FO TO IMMEDIATELY TURN R AND HE COMPLIED. I LOOKED OUTSIDE FOR CONFLICTING TFC ON ILS RWY 27L IN ATL. THERE I SAW A B767 ABEAM AND BELOW US. ABOUT THAT TIME APCH CALLED AND TOLD US TO TURN TO 300 DEG HDG TO REINTERCEPT THE LOC AND MAINTAIN 4000 FT MSL. WE RECAPTURED THE LOC AND GS FOR AN UNEVENTFUL LNDG.
