Narrative:

A commuter BE02 was en route at FL220 with TCASII. An air carrier A300 was an indianapolis departure, without TCASII. I was providing on-the-job training at the terre haute low altitude sector. The A300 was climbed to FL210, but read back FL220. I waited a few seconds to see if the trainee would catch the error, he didn't. I told the trainee to fix it. The pilot read back FL210. Next, the BE02 pilot said he had a 'TA' and was the traffic stopping at FL210. We asked the air carrier his altitude at FL214. He said he was level at FL210. Next computer update showed mode C at FL217. The BE02 pilot said 'boy that was close.' the air carrier cargo aircraft doesn't require TCASII. The BE02 may have changed altitude if they had the higher end TCASII. Management took no action because the A300 said he was level.

Title: PLTDEV WHEN CARGO A300 CLBED THROUGH ASSIGNED ALT OF FL210 AND CONFLICTED WITH A COMMUTER BE02 AT FL220. A300 FLC SAID THEY WERE LEVEL AT FL210. MODE C READOUT SHOWED AN ALT OF FL217. RPTR STATES MGMNT TOOK NO ACTION BECAUSE THE FLC SAID THEY WERE LEVEL. BE02 PLT RPTED INCIDENT AS BEING CLOSE.

Narrative: A COMMUTER BE02 WAS ENRTE AT FL220 WITH TCASII. AN ACR A300 WAS AN INDIANAPOLIS DEP, WITHOUT TCASII. I WAS PROVIDING ON-THE-JOB TRAINING AT THE TERRE HAUTE LOW ALT SECTOR. THE A300 WAS CLBED TO FL210, BUT READ BACK FL220. I WAITED A FEW SECONDS TO SEE IF THE TRAINEE WOULD CATCH THE ERROR, HE DIDN'T. I TOLD THE TRAINEE TO FIX IT. THE PLT READ BACK FL210. NEXT, THE BE02 PLT SAID HE HAD A 'TA' AND WAS THE TFC STOPPING AT FL210. WE ASKED THE ACR HIS ALT AT FL214. HE SAID HE WAS LEVEL AT FL210. NEXT COMPUTER UPDATE SHOWED MODE C AT FL217. THE BE02 PLT SAID 'BOY THAT WAS CLOSE.' THE ACR CARGO ACFT DOESN'T REQUIRE TCASII. THE BE02 MAY HAVE CHANGED ALT IF THEY HAD THE HIGHER END TCASII. MGMNT TOOK NO ACTION BECAUSE THE A300 SAID HE WAS LEVEL.
