   COMMENTS:  AWS 8907 HAD CEASED OPERATING ON AUGUST 22 1983.  INSPECTION SHOWED THAT WATER FROM MELTING SNOW HAD CORRODED ONE EDGE OF THE CPU BOARD.  THE DAMAGE ACTUALLY BROKE ONE OF THE TRACES ON THE BOARD.  THE BOARD WAS CLEANED AND REPAIRED.  ALSO, THE AWS BOX WAS SECURED SO THAT SNOW COULD NOT AS EASILY GET INTO THE BOX.
