## Discrepancy

APPROXIMATELY 40 MINUTES INTO FLIGHT WITH 2 PASSENGERS, AT 16,000 FT  THE COPILOT SIDE WINDOW OUTER LAYER CRACKED.   WE WERE IN IMC CONDITIONS FOR THE ENTIRE FLIGHT WITH SOME RAIN AND LIGHT SNOW.  THE CRACKING WAS PRECEEDED BY SOME ELECTRICAL ARCING ON THE CRACKED WINDSHIELD SIDE.  THE DECISION WAS MADE TO DECLARE AN EMERGENCY AND DIVERT TO THE CLOSEST AIRPORT.  DESCENDED AND FLEW THE ILS 6 APPROACH INTO AIRPORT 
UNEVENTFULLY.
