Narrative:
Approach controller was very busy when he cleared us for the river visual to 18 to dca. He then cleared an small transport for a visual to runway 15 at dca to parallel our course. The small transport was higher than we were but had us in sight. Approach then told us about the small transport which the first officer had in sight. As we continued the approach the small transport kept getting closer and was still high. After the first officer finished the checklist he looked outside just in time to see the small transport, still higher than us, go directly over our airplane. At this point I started a descent from 1200 to 900 ft per the approach and the tower issued a 250 heading to the small transport when the first officer saw him pull away on the 250 degree heading we were at 1000 ft and he was at 1100 to 1200 ft. The rest of the approach was uneventful.

Title: CLOSE PROX ACR-MLG GA-SMT 4 NW OF DCA ON RIVER VISUAL APCH.
Narrative: APCH CTLR WAS VERY BUSY WHEN HE CLRED US FOR THE RIVER VISUAL TO 18 TO DCA. HE THEN CLRED AN SMT FOR A VISUAL TO RWY 15 AT DCA TO PARALLEL OUR COURSE. THE SMT WAS HIGHER THAN WE WERE BUT HAD US IN SIGHT. APCH THEN TOLD US ABOUT THE SMT WHICH THE FO HAD IN SIGHT. AS WE CONTINUED THE APCH THE SMT KEPT GETTING CLOSER AND WAS STILL HIGH. AFTER THE FO FINISHED THE CHKLIST HE LOOKED OUTSIDE JUST IN TIME TO SEE THE SMT, STILL HIGHER THAN US, GO DIRECTLY OVER OUR AIRPLANE. AT THIS POINT I STARTED A DSCNT FROM 1200 TO 900 FT PER THE APCH AND THE TWR ISSUED A 250 HDG TO THE SMT WHEN THE FO SAW HIM PULL AWAY ON THE 250 DEG HDG WE WERE AT 1000 FT AND HE WAS AT 1100 TO 1200 FT. THE REST OF THE APCH WAS UNEVENTFUL.
