The 150 passengers, including a lap-held child, and 5 crewmembers evacuated the airplane via the forward and overwing exits. One flight attendant and four passengers were seriously injured, and the airplane was substantially damaged. The scheduled, domestic passenger flight was operating under the provisions of 14 Code of Federal Regulations Part 121 on an instrument flight rules flight plan. Visual meteorological conditions prevailed at the time of the accident.

The size and number of the birds ingested by the accident engines well exceeded the current bird-ingestion certification standards

The National Transportation Safety Board determines that the probable cause of this accident was the ingestion of large birds into each engine, which resulted in an almost total loss of thrust in both engines and the subsequent ditching on the Hudson River. Contributing to the fuselage damage and resulting unavailability of the aft slide/rafts were
– the Federal Aviation Administration’s (FAA) approval of ditching certification without determining whether pilots could attain the ditching parameters without engine thrust,
– the lack of industry flight crew training and guidance on ditching techniques, and
– the captain’s resulting difficulty maintaining his intended airspeed on final approach due to the task saturation resulting from the emergency situation.

Contributing to the survivability of the accident was :
– the decision-making of the flight crewmembers and their crew resource management during the accident sequence;
– the fortuitous use of an airplane that was equipped for an extended overwater flight, including the availability of the forward slide/rafts, even though it was not required to be so equipped;
– the performance of the cabin crewmembers while expediting the evacuation of the airplane; and
– the proximity of the emergency responders to the accident site and their immediate and appropriate response to the accident.
