NTSB events (1)

Accident · substantial damage

Jul 23, 2016 · Zamora, CA

The failure of both pilots to maintain an adequate visual lookout, which resulted in a midair collision. Also causal was the pilot's use of two sedating antihistamines and two impairing medication and the effect of sun glare on his visual lookout, which likely led to his inability to successfully see and avoid the other airplane.
