Investigation

The partially submerged plane was moored to a pier near the World Financial Center in Lower Manhattan, roughly 4 miles (6 km) downstream from the ditching location. The left engine, detached by the ditching, was recovered from the riverbed. On January 17 the aircraft was barged to New Jersey. The initial National Transportation Safety Board (NTSB) evaluation that the plane had lost thrust after a bird strike was confirmed by analysis of the cockpit voice and flight data recorders. Two days earlier the plane had experienced a less severe compressor stall, but the affected engine was restarted. A faulty temperature sensor was replaced, and inspection verified the engine had not been damaged in that incident.
