Narrative:

I was the PNF in a C172. We were told by daytona approach to 'maintain 1500 ft; report midfield downwind for runway 7R' with this instruction; we were switched over to tower and tower told us the same instruction; almost word for word. As we entered the pattern; we turned left and I called tower to report that we were on the midfield downwind. However; I didn't get an immediate response. The tower then called another aircraft and gave him instructions. About 10 seconds after the first call we were abeam the runway; and I called again. We began our descent; and were passing through approximately 1300 ft MSL when another aircraft passed below us; overtaking us; and missed us vertically about 100 ft. The tower immediately called us and told us to climb; which we were already doing. We extended our downwind as requested and landed without incident. As PNF; I think that the main contributions to this near miss were 2 factors. One; the traffic was never given to us as we were entering the pattern. If controller had said to follow the traffic; then this wouldn't have occurred. Or if controller had given us clearer instructions to not descend; then we wouldn't have had this issue either. The second cause is the other aircraft not looking for traffic in the pattern. A minor note; he was cruising about 120-130 KTS in the pattern; and was significantly faster than us in our same model cessna. Last; the tower was working about 5 or 6 aircraft in the pattern for runway 7R at daytona. Perhaps this traffic load was also a major factor in play for this. I think that this problem will continue to happen until more TA's are given.

Title: C172 PILOT REPORTS NMAC WITH ANOTHER C172 IN THE TRAFFIC PATTERN AT DAB FOR RWY 7R.

Narrative: I WAS THE PNF IN A C172. WE WERE TOLD BY DAYTONA APCH TO 'MAINTAIN 1500 FT; RPT MIDFIELD DOWNWIND FOR RWY 7R' WITH THIS INSTRUCTION; WE WERE SWITCHED OVER TO TWR AND TWR TOLD US THE SAME INSTRUCTION; ALMOST WORD FOR WORD. AS WE ENTERED THE PATTERN; WE TURNED L AND I CALLED TWR TO RPT THAT WE WERE ON THE MIDFIELD DOWNWIND. HOWEVER; I DIDN'T GET AN IMMEDIATE RESPONSE. THE TWR THEN CALLED ANOTHER ACFT AND GAVE HIM INSTRUCTIONS. ABOUT 10 SECONDS AFTER THE FIRST CALL WE WERE ABEAM THE RWY; AND I CALLED AGAIN. WE BEGAN OUR DSCNT; AND WERE PASSING THROUGH APPROX 1300 FT MSL WHEN ANOTHER ACFT PASSED BELOW US; OVERTAKING US; AND MISSED US VERTICALLY ABOUT 100 FT. THE TWR IMMEDIATELY CALLED US AND TOLD US TO CLB; WHICH WE WERE ALREADY DOING. WE EXTENDED OUR DOWNWIND AS REQUESTED AND LANDED WITHOUT INCIDENT. AS PNF; I THINK THAT THE MAIN CONTRIBUTIONS TO THIS NEAR MISS WERE 2 FACTORS. ONE; THE TFC WAS NEVER GIVEN TO US AS WE WERE ENTERING THE PATTERN. IF CTLR HAD SAID TO FOLLOW THE TFC; THEN THIS WOULDN'T HAVE OCCURRED. OR IF CTLR HAD GIVEN US CLEARER INSTRUCTIONS TO NOT DSND; THEN WE WOULDN'T HAVE HAD THIS ISSUE EITHER. THE SECOND CAUSE IS THE OTHER ACFT NOT LOOKING FOR TFC IN THE PATTERN. A MINOR NOTE; HE WAS CRUISING ABOUT 120-130 KTS IN THE PATTERN; AND WAS SIGNIFICANTLY FASTER THAN US IN OUR SAME MODEL CESSNA. LAST; THE TWR WAS WORKING ABOUT 5 OR 6 ACFT IN THE PATTERN FOR RWY 7R AT DAYTONA. PERHAPS THIS TFC LOAD WAS ALSO A MAJOR FACTOR IN PLAY FOR THIS. I THINK THAT THIS PROB WILL CONTINUE TO HAPPEN UNTIL MORE TA'S ARE GIVEN.
