Primary finding
Probable cause
The pilot's intentional low-altitude operation, which resulted in his failure to maintain clearance from unmarked utility wires.
Investigator assessment
Analysis narrative
Shortly after departing and while flying along a river, the airplane struck two of five unmarked utility wires that spanned the river. The airplane subsequently impacted water, which resulted in substantial damage to the airframe and minor injuries to the pilot and passenger. When asked how the accident could have been prevented, the pilot stated, "Increase altitude minimums by at least double to ensure adequate reaction time to avoid obstacles."
