An air carrier MD88 flight was diverted because the left engine ingested ice during takeoff and continued to surge on climb out and in-flight. Preflight inspection had revealed heavy clear ice and 1/4 inch of snow. The captain believes that clear ice may have escaped ground crew detection after deicing procedure was accomplished.

Narrative:
Ingested ice on takeoff, after deicing in cvg. Aircraft was covered with heavy coat of clear ice and about 1/4 inch of snow. I believe that while all the snow was removed, some clear ice remained after deice, and was not seen by deice crews. At rotation, the #1 engine surged and compressor stalled. After climb out from the icing conditions, the aircraft was diverted to atlanta. #1 engine continued to surge and stall at higher power settings, but ran ok at reduced thrust. Landing at atl uneventful.

Narrative: INGESTED ICE ON TKOF, AFTER DEICING IN CVG. ACFT WAS COVERED WITH HVY COAT OF CLR ICE AND ABOUT 1/4 INCH OF SNOW. I BELIEVE THAT WHILE ALL THE SNOW WAS REMOVED, SOME CLR ICE REMAINED AFTER DEICE, AND WAS NOT SEEN BY DEICE CREWS. AT ROTATION, THE #1 ENG SURGED AND COMPRESSOR STALLED. AFTER CLBOUT FROM THE ICING CONDITIONS, THE ACFT WAS DIVERTED TO ATLANTA. #1 ENG CONTINUED TO SURGE AND STALL AT HIGHER PWR SETTINGS, BUT RAN OK AT REDUCED THRUST. LNDG AT ATL UNEVENTFUL.
