It turns out that the US Airways jet that landed in the Hudson River last week didn’t just have a problem with birds.

New reports out today say that Flight 1549 had engine compressor failure just two days before heroic pilot Chesley "Sully" Sullenberger landed the Airbus 320 in the water, saving everyone aboard.

The National Transportation Safety Board said Monday that its examination of the plane’s maintenance records show "there was an entry in the aircraft’s maintenance log that indicates a compressor stall occurred on January 13."

But NTSB investigators so far have not uncovered "any anomalies or malfunctions with Flight 1549" from the time it left LaGuardia Airport to the time Sullenberger reported a bird strike and loss of engine power, the spokesman said.

CNN reported Monday that passengers on Flight 1549 say they heard loud bangs and scrapings right before the emergency landing announcement. Such sounds are common with compressor failures. But passengers said the situation calmed down and they continued on to Charlotte, NC. Those details, however, shed new light on last week’s crash — and will surely complicate the investigation.
