A320 crash in the Hudson River - history of stalls?
(OP)
Has there been confirmation that this very aircraft was involved in an inflight engine stall during climb that precipitated an AD? Geraldo Rivera talked about it a few days ago.

if there was this sort of "serious" event in the past, don't you think the engines would have been changed out ?
if the cause of the Hudson River ditching was bird strike, how would the previous event have affected this one ?
of course what they're chasing is the chance that the earlier event was "waved off" by Airbus, EASA, and the FAA (even though there was and AD issued for some underlying problem) and that the plane was affected in some way and this exasperated the recent bird strike.
of course too, there is the possibility that if this did happen then the earlier event allowed the plane to survive the bird strike (creating a "leak-before-burst" situation) but nobody would claim credit for that lucky chance.

There is a lot of chatter about the A321 that crashed into the Hudson had a stall history, but nothing from an official source (doing a quick search)

For the non engine guys: The Stall event is characterized by an instantaneous and severe reduction air flow while the compressor is still running at speed – at a certain pressure ratio. The pressure recovery is sudden (read loud bang) as the flow is restored.
Note to Plasgears... Sorry, just having a bit of fun at GE's expense. GE engines tend to have better fuel efficiencies than PW and RR.

For single birds, the engine just has to tolerate the impact without endangering the aircraft, but can fail completely.
The critical bit is what the certifying authorities dictate a flocking bird weighs. 20 years ago, the limit was 1.5lb, with the single bird tested at 4lb. Later, the goal was shifted to a 2.5lb flocking bird and an 8lb singleton. I beleive that there is at least talk, if it hasn't made it into the certification requirements already, of the flocking bird test going at 4lb and the singleton up round 12lb somewhere.
Now some will comment that canda geese flock, but the engine manufacturers will design and test to what the FAA and JAA say are the limits, so if you want to blame anyone, blame them.

NTSB Update On Hudson River Ditching: Feather Found
From : AVWEB
The NTSB on Wednesday afternoon released new factual information in connection with its continuing investigation of US Airways Flight 1549, the Airbus 320 that ditched into the Hudson River in New York on Jan. 15. Factual updates from the board are generally considered preliminary information and no conclusions are drawn from the findings. The right engine has been externally examined and documented, the safety board said. An examination of the first-stage fan blades revealed evidence of soft body impact damage. Three of the variable guide vanes are fractured and two are missing. The engine's electronic control unit is missing and numerous internal components of the engine were significantly damaged. What appears to be organic material was found in the right engine and on the wings and fuselage. Samples of the material have been provided to the U.S. Department of Agriculture for a complete DNA analysis. A single feather was found attached to a flap track on the wing. It is being sent to bird identification experts at the Smithsonian. The left engine has been located in about 50 feet of water near the area of the Hudson River where the aircraft ditched. The NTSB is working with federal, state and local agencies to recover the engine, which is expected to occur sometime on Thursday.
The NTSB also learned that the right engine experienced a surge during a flight on Jan. 13, and a temperature probe was subsequently replaced. The NTSB's Survival Factors group is interviewing passengers to learn more about the events surrounding the ditching and the emergency evacuation and rescue, and the Operations and Human Performance group is interviewing US Airways flight operations training personnel. The on-scene documentation of the airplane is expected to be completed by the end of the week. The aircraft will then be moved to a more permanent storage site where more detailed documentation of the damage can be performed at a later date.
Now, somebody know what happened with the LEFT engine ? any
NTSB preliminary report about it ?
