: NTSB investigators either traveled in support of this investigation or conducted a significant amount of investigative work without any travel, and used data obtained from various sources to prepare this public aircraft accident report.
The airplane had made a dry pass on the fire zone, then circled around to make a second pass and release its load of 2,450 gallons of retardant. According to witnesses, the airplane struck trees while in a nose low, right wing low attitude. Upon ground impact, the airplane exploded and burned. Investigation revealed no evidence of preimpact airframe, engine, propeller, or flight control failure/malfunction. The first officer, an initial attack trainee pilot, was in the left seat and the captain was in the right seat. Toxicology tests of the first officer indicated 0.031 ug/ml brompheniramine, 0.011 ug/ml chlorpheniramine in kidney fluid, and 0.142 brompheniramine, 0.072 chlorpheniramine in liver fluid. Both medications are over-the-counter antihistamines with sedative effects.
The National Transportation Safety Board determines the probable cause(s) of this accident to be: Failure of the copilot to maintain both lateral and vertical clearance from the trees, and failure of the captain to provide adequate supervision of the flight. Full narrative available
