Analysis
During level off at 16,000 ft with a sea level cabin pressure (6 PSI differential pressure), the crew heard a 'pop', then the coplt's window blew out. Debris, including the glareshield, exited the cockpit & injured the copilot. The window was a single thickness acrylic, manufactured by ppg (pn 26-2L 383-006). The window was in service 12,158 hrs since new in 1979. Fatigue originated near the lower rear corner under the edge of the window retainer strip. Cause of the fatigue was not determined. White paint & sealant material were at the fatigue origin. A scribe line was in close proximity to the origin.
