Probable cause

A separation of the window from the airframe for undetermined reasons.

NTSB narrative

While en route the pilot reported there was a sudden explosion and the right window and portion of the right roof separated from the airplane. He performed an emergency descent and landed uneventfully. The airplane was initially documented but was repaired before a detailed postaccident examination could be completed. The airframe could not be examined, and the separated window was not located; therefore, the reason for the separation could not be determined.

Analysis

Primary failure mode
Mechanical failure
First missed decision gate
Pilot could have replaced the windows before the flight to prevent failure.
