Narrative:

At mgw sector at ZOB, a pit departure push was underway. Thunderstorms in the sector created many deviations and 'uret' had disabled so we were in the process of marking strips and coordinating deviating traffic and point outs. The radar controller mistakenly issued FL280 instead of FL260 as believed. I was on a landline at the time of the transmission. When air carrier X went through FL260, radar controller issued a vector to separate aircraft.

Original NASA ASRS Text

Title: ZOB RADAR CTLR ISSUED A CLB CLRNC THROUGH AN OCCUPIED ALT RESULTING IN A LOSS OF SEPARATION.

Narrative: AT MGW SECTOR AT ZOB, A PIT DEP PUSH WAS UNDERWAY. TSTMS IN THE SECTOR CREATED MANY DEVS AND 'URET' HAD DISABLED SO WE WERE IN THE PROCESS OF MARKING STRIPS AND COORDINATING DEVIATING TFC AND POINT OUTS. THE RADAR CTLR MISTAKENLY ISSUED FL280 INSTEAD OF FL260 AS BELIEVED. I WAS ON A LANDLINE AT THE TIME OF THE XMISSION. WHEN ACR X WENT THROUGH FL260, RADAR CTLR ISSUED A VECTOR TO SEPARATE ACFT.
