What happened
During cruise flight over a river, the pilot experienced a sudden failure of the aircraft's windshield. The event occurred without prior warning, resulting in the immediate loss of the forward glazing. The pilot initially suspected that the failure was caused by a bird strike, though no avian impact was confirmed.
Following the structural breach, the airplane became directionally unstable. The aerodynamic forces acting on the airframe made controlled flight increasingly difficult. Recognizing the severity of the situation and the inability to maintain stable heading, the pilot decided to execute an emergency ditching in the river below.
The investigation
Post-accident examination of the site revealed significant environmental factors that may have contributed to the incident. Local sheriff's department personnel located a downed wire running across the river in the vicinity of the accident site.
The presence of this wire suggests it could have been involved in the windshield failure, either through direct impact or by creating an electrical discharge hazard. The investigation focused on determining whether the wire was struck by the aircraft or if the windshield failed independently.
Findings
The primary finding was the catastrophic loss of the windshield during flight. This led directly to directional instability, forcing the pilot to abandon the aircraft in a river environment. The discovery of the downed wire provides a critical clue regarding the cause of the initial failure.
