## Discrepancy

WHILE CRUISING AT APPROX. 32,000 FT, THE RH HEATED SIDE WINDSCREEN BASICALLY SHATTERED. NO PREVIOUS SCRATCHES KNOWN. NO IMPACT MADE, SUCH AS BIRD STRIKE. PILOTS REPORTED NOTHING OUT OF THE ORDINARY GOING ON. SIMPLY AND SUDDENLY SHATTERED. WINDOW STAYED INTACT. CREW DIVERTED TO THE PHOENIX SKY HARBOR AIRPORT.
