Lubbock, TX, USA
N312MB
BEECH B100
About an hour after departure, while the airplane was in cruise flight, the pilot and passenger heard a “cracking noise” and noticed that the right windshield had cracked. The windshield remained in place and pressurization was not lost. The pilot notified the air traffic controller that he had a cracked windshield and diverted to a nearby airport. The airplane landed uneventfully and examination revealed substantial cracking damage to the right-side windshield inner pane. The windshield was disposed of before further testing could be performed to determine the failure mode.
