Narrative:
Just prior to turning right to join the friant transit of the frogo 5 degree the outer pane of the center windshield shattered. We overflew the transition slightly due to more pressing circumstances and then turned once we completed our abnormal procedures checklist. Callback conversation with reporter revealed the following information. Reporter states flight manual does not consider a windshield failure (outer pane) to be an emergency. Requires crew to assure heat is turned off and indicates not to exceed 300 KTS below 20000'. Captain chose to descend to lower altitude and depressurize a bit. Talked with maintenance to be sure of proper procedures and where they wanted the aircraft. Felt failure to turn was not the major problem under the circumstances. On inspection, it was found that most of the screws holding the windshield were stripped. Possible over torquing.

Title: MLG FLT CREW DEPARTING ON SID HAS OUTER PANE OF CENTER WINDSHIELD SHATTER. OVERFLEW TURN TO TRANSITION ROUTE.
Narrative: JUST PRIOR TO TURNING R TO JOIN THE FRIANT TRANSIT OF THE FROGO 5 DEG THE OUTER PANE OF THE CTR WINDSHIELD SHATTERED. WE OVERFLEW THE TRANSITION SLIGHTLY DUE TO MORE PRESSING CIRCUMSTANCES AND THEN TURNED ONCE WE COMPLETED OUR ABNORMAL PROCS CHKLIST. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO. RPTR STATES FLT MANUAL DOES NOT CONSIDER A WINDSHIELD FAILURE (OUTER PANE) TO BE AN EMER. REQUIRES CREW TO ASSURE HEAT IS TURNED OFF AND INDICATES NOT TO EXCEED 300 KTS BELOW 20000'. CAPT CHOSE TO DSND TO LOWER ALT AND DEPRESSURIZE A BIT. TALKED WITH MAINT TO BE SURE OF PROPER PROCS AND WHERE THEY WANTED THE ACFT. FELT FAILURE TO TURN WAS NOT THE MAJOR PROB UNDER THE CIRCUMSTANCES. ON INSPECTION, IT WAS FOUND THAT MOST OF THE SCREWS HOLDING THE WINDSHIELD WERE STRIPPED. POSSIBLE OVER TORQUING.
