A pilot on approach to CMA Runway 26 reported a near miss with an aircraft which ATC claimed they reported but the transmission was not heard or acknowledged by the reporter or his passenger.

Narrative

I was handed off to Mugu by SOCAL east of COOGA Intersection. They told me to cross COOGA at 4;000 FT and cleared me for the approach; contact Tower at CECEE. Then I think they told me to go to Tower before CECEE; which I did. I was on final approach to CMA; talking with the Tower; and was cleared to land. I saw the other airplane; I believe a high-wing Cessna; in what appeared to be a climbing right turn; about 50 FT ahead. He may have just looked like he was climbing because I was descending; or he may have been in level flight turning base to final. I don't know where he went; but I continued the approach. I spoke with the Tower Supervisor after landing; he said he would listen to the tape and get back to me; which he did. It seems the pilot of the other airplane had been issued traffic (me) at about 2 miles; but it wasn't until we got really close; that the Controller called the traffic for me. I didn't hear it; and neither did my passenger (also an IFR pilot); but to be fair; it's possible that we both could have missed it. Also; after listening to the tape; the Tower Supervisor said the Controller called traffic on my left -- this guy came from the right. I didn't take any corrective action - didn't have time - and I don't know if the other guy did or not. Maybe we just got lucky. I can't speak for anyone else's physical condition; but I had gotten plenty of sleep the night before; I wasn't hungry; we'd had a pleasant hour's flight; I wasn't distracted and I wasn't in a hurry to get anywhere special. CMA is hugely busy on weekends because there's a great restaurant on the field. I don't know how much experience the controllers have; but I would think that the most experienced ones should be working at those times.
