Narrative:

Returning deadhead to dpa where airplane is based. For practice, shot GPS runway 1L approach under ATC control. Turned over to dpa tower while about 11 mi south of field. Local controller agreed with pilot request for landing on runway 28. Told pilot to report breaking off the approach. Pilot did so about 3 mi south when entering the left downwind. Controller's only response was, 'you have traffic 1 O'clock, 1 - 1 1/2 mi, 2300 ft.' this was the same location as reporter's airplane. Controller did little to resolve the situation, virtually letting pilots separate themselves. I've been flying for over 25 yrs and have never been put in such a situation in the traffic pattern. There was no warning other than when collision was very possible. Controller needs to anticipate future locations of aircraft and advise them before separation becomes minimal. Pilot needs to remember that controllers are fallible.

Original NASA ASRS Text

Title: PLT OF BE300 HAS NMAC WITH ACFT IN TFC PATTERN BUT WITH NO ADVISORY ISSUED.

Narrative: RETURNING DEADHEAD TO DPA WHERE AIRPLANE IS BASED. FOR PRACTICE, SHOT GPS RWY 1L APCH UNDER ATC CTL. TURNED OVER TO DPA TWR WHILE ABOUT 11 MI S OF FIELD. LCL CTLR AGREED WITH PLT REQUEST FOR LNDG ON RWY 28. TOLD PLT TO RPT BREAKING OFF THE APCH. PLT DID SO ABOUT 3 MI S WHEN ENTERING THE L DOWNWIND. CTLR'S ONLY RESPONSE WAS, 'YOU HAVE TFC 1 O'CLOCK, 1 - 1 1/2 MI, 2300 FT.' THIS WAS THE SAME LOCATION AS RPTR'S AIRPLANE. CTLR DID LITTLE TO RESOLVE THE SIT, VIRTUALLY LETTING PLTS SEPARATE THEMSELVES. I'VE BEEN FLYING FOR OVER 25 YRS AND HAVE NEVER BEEN PUT IN SUCH A SIT IN THE TFC PATTERN. THERE WAS NO WARNING OTHER THAN WHEN COLLISION WAS VERY POSSIBLE. CTLR NEEDS TO ANTICIPATE FUTURE LOCATIONS OF ACFT AND ADVISE THEM BEFORE SEPARATION BECOMES MINIMAL. PLT NEEDS TO REMEMBER THAT CTLRS ARE FALLIBLE.
