On January 15 , 2009 , US Airways Flight 1549 , an Airbus A320 , ditched in the Hudson River about five minutes after takeoff . The apparent cause was compressor stall in both CFM International CFM56-5B engines after flying through a flock of birds about 90 seconds after takeoff . This same aircraft may have suffered a compressor stall on the right engine two days earlier . After an incident in which an Airbus A321-200 experienced compressor stalls on both engines during initial climbout on December 15 , 2008 , an EASA Emergency Airworthiness Directive 2008-228 requested operators of CFM56-5B engines to monitor exhaust gas temperatures ( EGT ) for deterioration and make sure that at least one engine shows less than 80 °C deterioration in its EGTs . The FAA have issued the same requirements as Airworthiness Directive AD 2009-01-01 with immediate effect
