Narrative:

Air crew arrived at airport to originate flight tvc-dtw. Conditions at tvc 1000 overcast 1/2 mi and snowing. Snow removal in progress. Braking action poor. Passenger were boarded and aircraft was de-iced. Air crew informed by ground crew that de-icing was completed. Aircraft was started, engine heat applied and takeoff accomplished within 5 mins of taxi out. During climb out passing 15000 ft left engine made popping noise, followed by minor vibration. Captain retarded power on left engine, and vibration ceased. Captain elected not to shut down engine and continued to dtw, due to poor WX conditions at tvc and en route (i.e., grr and lan). Captain made uneventful landing in dtw. Investigation on ground, discovered left engine compressor damage. On trailing edge of flap on top of wing was 2-3 ft sheet of 1/4 inch thick ice. Deplaning passenger said he saw ice fly off wing and into engine. Reason for damage: ice ingestion into turbojet engine. Contributing factor: inadequate de-icing of aircraft. Corrective action: better training for airline de-ice crews.

Original NASA ASRS Text

Title: ACR MLG ICE INGESTION DURING CLB CAUSES ENG DAMAGE.

Narrative: AIR CREW ARRIVED AT ARPT TO ORIGINATE FLT TVC-DTW. CONDITIONS AT TVC 1000 OVCST 1/2 MI AND SNOWING. SNOW REMOVAL IN PROGRESS. BRAKING ACTION POOR. PAX WERE BOARDED AND ACFT WAS DE-ICED. AIR CREW INFORMED BY GND CREW THAT DE-ICING WAS COMPLETED. ACFT WAS STARTED, ENG HEAT APPLIED AND TKOF ACCOMPLISHED WITHIN 5 MINS OF TAXI OUT. DURING CLB OUT PASSING 15000 FT L ENG MADE POPPING NOISE, FOLLOWED BY MINOR VIBRATION. CAPT RETARDED PWR ON L ENG, AND VIBRATION CEASED. CAPT ELECTED NOT TO SHUT DOWN ENG AND CONTINUED TO DTW, DUE TO POOR WX CONDITIONS AT TVC AND ENRTE (I.E., GRR AND LAN). CAPT MADE UNEVENTFUL LNDG IN DTW. INVESTIGATION ON GND, DISCOVERED L ENG COMPRESSOR DAMAGE. ON TRAILING EDGE OF FLAP ON TOP OF WING WAS 2-3 FT SHEET OF 1/4 INCH THICK ICE. DEPLANING PAX SAID HE SAW ICE FLY OFF WING AND INTO ENG. REASON FOR DAMAGE: ICE INGESTION INTO TURBOJET ENG. CONTRIBUTING FACTOR: INADEQUATE DE-ICING OF ACFT. CORRECTIVE ACTION: BETTER TRAINING FOR AIRLINE DE-ICE CREWS.
