What was found
ACCORDING TO THE PILOT IN COMMAND’S REPORT, THEY HAD TO DEICE THE PLANE BEFORE TAKEOFF. THEN, ON TAKEOFF ROLL, DURING ROTATION, THERE WAS A LOUD BANG AND VIBRATION. THE CAPTAIN’S FIRST THOUGHT WAS THAT A TIRE HAD BLOWN. ONCE AIRBORNE, THE VIBRATION CONTINUED ACCOMPANIED BY LOUD BANGING. THE NR 1 ENGINE WAS NOT DEVELOPING POWER AND SEEMED TO BE HAVING COMPRESSOR STALLS. THE FIRST OFFICER ADVISED THE TOWER OF OUR EMERGENCY AND REQUESTED AN IMMEDIATE RETURN TO THE AIRPORT. PILOTS ACCOMPLISHED THE ENGINE FAILURE AND SHUTDOWN CHECKLIST FOLLOWED BY THE ONE ENGINE INOPERATIVE LANDING CHECKLIST AND THEN USED AN ILS APPROACH TO LAND AT THE AIRPORT ORIGINALLY DEPARTED FROM.
