Narrative:

Entered the downwind behind an small aircraft. There was a number of aircraft in the class D airspace and the tower frequency was extremely busy. While following the small aircraft and waiting to communicate with tower to report established on the downwind, a low wing, reciprocating engine aircraft overtook our aircraft, passing directly below. Estimated separation 200 ft. Our aircraft was flying at 85 KIAS. The other aircraft was probably cruising at over 100 KIAS. After passing our aircraft, the aircraft climbed to traffic pattern altitude (1100 ft MSL). At republic airport, near misses are common. Unfortunately, they are not reported by pilots or ATC. Republic is mainly utilized by GA and the bulk of traffic is training. Many times during the day, controllers are overwhelmed by traffic demands. Increased controled procedures must be implemented to prevent a midair incident. Perhaps, implementing a TRSA program and educating local pilots of the hazards.

Original NASA ASRS Text

Title: NMAC OCCURS IN TFC WHEN ONE SMA OVERTAKES ANOTHER.

Narrative: ENTERED THE DOWNWIND BEHIND AN SMA. THERE WAS A NUMBER OF ACFT IN THE CLASS D AIRSPACE AND THE TWR FREQ WAS EXTREMELY BUSY. WHILE FOLLOWING THE SMA AND WAITING TO COMMUNICATE WITH TWR TO RPT ESTABLISHED ON THE DOWNWIND, A LOW WING, RECIPROCATING ENG ACFT OVERTOOK OUR ACFT, PASSING DIRECTLY BELOW. ESTIMATED SEPARATION 200 FT. OUR ACFT WAS FLYING AT 85 KIAS. THE OTHER ACFT WAS PROBABLY CRUISING AT OVER 100 KIAS. AFTER PASSING OUR ACFT, THE ACFT CLBED TO TFC PATTERN ALT (1100 FT MSL). AT REPUBLIC ARPT, NEAR MISSES ARE COMMON. UNFORTUNATELY, THEY ARE NOT RPTED BY PLTS OR ATC. REPUBLIC IS MAINLY UTILIZED BY GA AND THE BULK OF TFC IS TRAINING. MANY TIMES DURING THE DAY, CTLRS ARE OVERWHELMED BY TFC DEMANDS. INCREASED CTLED PROCS MUST BE IMPLEMENTED TO PREVENT A MIDAIR INCIDENT. PERHAPS, IMPLEMENTING A TRSA PROGRAM AND EDUCATING LCL PLTS OF THE HAZARDS.
