Austral DC-9 in 1997

[Stubenfliege]

Hi,

in 1997 a DC-9 from the argentine airline Austral crashed near Nuevo Berlin/Uruguay, killing all 75 occupants.
While diverting storms on their way to Buenos Aires, the a/c dived from FL257 into a swamp.

In a article in the Aviation Week, a failure of the pitot heater was cited as contributed cause of the crash.

Is there more information about this crash? Is there a official report out there?

The accident was investigated by urguayan authorties.

Thanks in advance,
