Narrative:

We were on a 5 mile final (just inside budde) to bur runway 8 descending through 2;300 ft MSL; just past the vny airport. Weather was clear with good visibility. Aircraft was configured with landing gear down; flaps 25 degrees; speed 155 KTS. We were slowing and preparing to extend flaps to 40 degrees for landing. Inside of budde; we received a TCAS TA for traffic that was depicted on the map display at 11 o'clock position less than 1 mile. Within seconds of the tower call; we received an RA with the command to 'climb.' the TCAS depicted the traffic at 12 o'clock position; inside 1 mile; and 300 ft below us. The first officer added power and complied with the RA. We climbed approximately 300 ft when the TCAS announced 'clear of conflict;' at which point we configured to flaps 40 degrees and reestablished the aircraft on the glide path. We were stabilized on the glide path by 800 ft afl. Landing was normal. I discussed the incident with the bur tower controller later. He informed me that the traffic that caused my RA was in the pattern at vny and that he had talked to the vny tower about the conflict. He said traffic conflicts between commercial traffic inbound to bur with vny pattern traffic are a common occurrence. Vny airport should discontinue traffic patterns east of the airport. There have been too many close calls in this airspace. Inexperienced VFR pilots cannot be counted on to stay within the horizontal and vertical limits of the pattern at vny; as evidenced by the high frequency of traffic conflicts in this area. If something is not changed; a midair collision is not a question of if; but when.
