The NFCT directed reporter to join with other aircraft in right traffic while numerous aircraft were flying left traffic. The NFCT lost track of his sequencing resulting in calling the left base in conflict with a right base. When within 500 ft horizontal with the merging traffic the reporter recognized the conflict and broke out of the pattern to be resequenced for landing.

Narrative:
I had reported as instructed on a right downwind for runway 22. There were 2 or 3 aircraft in left closed traffic for the same runway. Additional traffic was a C172 ahead on a right base and a navajo and guard helicopter entering behind me. Per tower instruction, I extended my downwind and indicated that the C172 I was following was not in sight. When a C172 passed by on final, I asked if this was my traffic, and I received no answer. I continued the downwind. I asked tower to call my base, which they did. After turning final, the tower indicated to another aircraft 'you are #1 for the runway.' I looked up and saw a low wing single converging at my altitude. I exited the final, and was resequenced for landing. The nonstandard procedure at this NFCT is to use both right and left traffic simultaneously. This, coupled with a greater than normal traffic load, led to the controller losing track of his sequencing, and the subsequent near miss.
Original NASA ASRS Text
Title: THE NFCT DIRECTED RPTR TO JOIN WITH OTHER ACFT IN R TFC WHILE NUMEROUS ACFT WERE FLYING L TFC. THE NFCT LOST TRACK OF HIS SEQUENCING RESULTING IN CALLING THE L BASE IN CONFLICT WITH A R BASE. WHEN WITHIN 500 FT HORIZ WITH THE MERGING TFC THE RPTR RECOGNIZED THE CONFLICT AND BROKE OUT OF THE PATTERN TO BE RESEQUENCED FOR LNDG.
Narrative: I HAD RPTED AS INSTRUCTED ON A R DOWNWIND FOR RWY 22. THERE WERE 2 OR 3 ACFT IN L CLOSED TFC FOR THE SAME RWY. ADDITIONAL TFC WAS A C172 AHEAD ON A R BASE AND A NAVAJO AND GUARD HELI ENTERING BEHIND ME. PER TWR INSTRUCTION, I EXTENDED MY DOWNWIND AND INDICATED THAT THE C172 I WAS FOLLOWING WAS NOT IN SIGHT. WHEN A C172 PASSED BY ON FINAL, I ASKED IF THIS WAS MY TFC, AND I RECEIVED NO ANSWER. I CONTINUED THE DOWNWIND. I ASKED TWR TO CALL MY BASE, WHICH THEY DID. AFTER TURNING FINAL, THE TWR INDICATED TO ANOTHER ACFT 'YOU ARE #1 FOR THE RWY.' I LOOKED UP AND SAW A LOW WING SINGLE CONVERGING AT MY ALT. I EXITED THE FINAL, AND WAS RESEQUENCED FOR LNDG. THE NONSTANDARD PROC AT THIS NFCT IS TO USE BOTH R AND L TFC SIMULTANEOUSLY. THIS, COUPLED WITH A GREATER THAN NORMAL TFC LOAD, LED TO THE CTLR LOSING TRACK OF HIS SEQUENCING, AND THE SUBSEQUENT NEAR MISS.
