## Discrepancy

AFTER DEPARTURE IN CLIMB THROUGH APPROXIMATELY 12000 FT. COPILOTS SIDE WINDOW SHATTERED. FLIGHT CREW DECLARED EMERGENCY AND RETURNED TO ORIGIN AIRPORT, WHILE STILL IN FLIGHT FLIGHT CREW REPORTS SEEING SPARKS AND BURNING SMELL COMING FROM WINDOW AND WINDOW CONTINUING TO CRACK WHILE AIRCRAFT DESCENDED ON APPROACH TO AIRPORT. COPILOTS SIDE WINDOW P/N 401-384001-0010 S/N 07081H9414 HAD SAME TSN AS THE AIRCRAFT. THE ISSUE OF SHATTERING PILOTS AND COPILOTS SIDE WINDOWS IN THE HAWKER 4000 CONTINUES TO BE AN UNRESOLVED PROBLEM IN THIS MODEL AIRCRAFT. TEXTRON (TC HOLDER) AND PPG WINDOW MFG. HAVE NOT YET EXAMINED THE WINDOW OR SUGGESTED ANY NEW INSPECTIONS TO THE WINDOW OR THE WINDOW FRAME FOR THIS ONGOING HAZARD TO PILOTS SAFETY IN THE COCKPIT.
