Narrative:

Aircraft was cleared direct keating (etg) VOR. Pilot read back 'beauty,' which turns out to be a fix along the arrival after etg. Radar controller caught bad readback and tried to correct pilot, but pilot did not acknowledge correction. Route discrepancy was not noticed until well across ZOB airspace. Rptedly, separation was never lost with other aircraft, but workload greatly increased at sector where error was noticed.

Original NASA ASRS Text

Title: ZID CTLR CORRECTS INCORRECT READBACKS BUT DOES NOT OBTAIN PLT VERIFICATION OF INCORRECT CLRNC. RTE DEV OBSERVED AND CORRECTED IN ZOB AIRSPACE.

Narrative: ACFT WAS CLRED DIRECT KEATING (ETG) VOR. PLT READ BACK 'BEAUTY,' WHICH TURNS OUT TO BE A FIX ALONG THE ARR AFTER ETG. RADAR CTLR CAUGHT BAD READBACK AND TRIED TO CORRECT PLT, BUT PLT DID NOT ACKNOWLEDGE CORRECTION. RTE DISCREPANCY WAS NOT NOTICED UNTIL WELL ACROSS ZOB AIRSPACE. RPTEDLY, SEPARATION WAS NEVER LOST WITH OTHER ACFT, BUT WORKLOAD GREATLY INCREASED AT SECTOR WHERE ERROR WAS NOTICED.
