Narrative:

I was cleared visual to runway 24. Told of light twin to left and saw him briefly. At that time, aircraft was slightly ahead of me. I flew a tight right base and gained a 1/2 mi final. Landed without incident. Captain gets call from tower to call pilot of light twin. Was told captain saw him at all times. Captain never advised me if I had any conflict with twin. I never did see aircraft in my descent on base. In my opinion, tower did a poor job of control as light twin asked, on his own, for runway 30 to solve any conflict.

Narrative: I WAS CLRED VISUAL TO RWY 24. TOLD OF LIGHT TWIN TO L AND SAW HIM BRIEFLY. AT THAT TIME, ACFT WAS SLIGHTLY AHEAD OF ME. I FLEW A TIGHT R BASE AND GAINED A 1/2 MI FINAL. LANDED WITHOUT INCIDENT. CAPT GETS CALL FROM TWR TO CALL PLT OF LIGHT TWIN. WAS TOLD CAPT SAW HIM AT ALL TIMES. CAPT NEVER ADVISED ME IF I HAD ANY CONFLICT WITH TWIN.
