Aircraft; Human Factors
While on visual approach to Runway 09R at 2;000 MSL on right downwind per clearance; I was instructed to extend my downwind by the Tower Controller and that he would call my base turn. He called traffic to me at 3 miles; 2 o'clock position at same altitude and converging from right to left. I did not immediately establish visual contact with the traffic. The Controller called the other aircraft 3 times to alert him as to my position. The other aircraft never gained visual contact with me. Almost immediately after another call to me to point out the traffic I gained visual contact and received the RA to 'monitor vertical speed.' I informed ATC that I had traffic and was immediately descending to avoid conflict. Controller called the other aircraft and instructed them to maintain 2;000. I passed approximately 300 feet below the other aircraft. I resumed my assigned heading and upon clearance to land resumed visual approach and landed without incident.
