## Analysis

DURING A DESCENT OF 400-500 FPM AT 120-125 MPH THE WINDSHIELD BLEW INTO THE AIRCRAFT. A PORTION OF THE WINDSHIELD REMAINED ATTACHED TO THE ACFT, FOLDED UP SO AS TO JUT ABOVE THE CABIN ROOF AND ACTED AS A SPOILER. LEVEL FLIGHT COULD NOT BE MAINTAINED DUE TO THE INCREASED DRAG AND A FORCED LANDING WAS MADE IN A PLOWED FIELD. THE PASSENGER REPORTED THATTHERE WAS A PRE-EXISTING CRACK IN THE WINDSHIELD 8 TO 10 INCHES IN LENGTH FROM THE RIGHT CORNER TOWARD THE CENTER. THE ENDS OF THE CRACK WERE STOP DRILLED AND BOLTS INSTALLED IN THE DRILLED HOLES.

From the NTSB's public API. Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model.
