## Discrepancy

THE RIGHT WINDSHIELD CRACKED WHILE CLIMBING THROUGH FL 200.  THE WINDHIELD HEAT HAD BEEN ON CONTINUOUSLY SINCE TAKEOFF FROM KAGC.  THE PILOT STATED HE HEARD A LOUD POPPING NOISE JUST PRIOR TO THE WINDSHIELD CRACKING.  THE PILOT FLYING DECLARED AN EMERGENCY TO ATC, REDUCED AIRSPEED, INITIATED A DESCENT TO 10,000 FEET AND ALTERED COURSE TO RETURN TO KAGC.  THE AIRCRAFT LANDED WITHOUT FURTHER INCIDENT.  INSPECTION AFTER LANDING REVEALED THE OUTER WINDSHIELD PLY ONLY WAS CRACKED IN A SPIDER WEB PATTERN ENCOMPASSING THE ENTIRE WINDSHIELD.
