## Analysis

THE PRIVATE PLT WAS SPRAYING CROPS DURING AN AERIAL APPLICATION FLIGHT. DURING A RIGHT TURN AT THE END OF A SPRAY RUN, HE SAID HE DIVERTED HIS ATTENTION INTO THE COCKPIT TO CHECK THE METERING RATE, AND MAY HAVE INADVERTENTLY PUSHED THE CONTROL STICK FORWARD. WHEN HE LOOKED OUT AGAIN, HE SAW THAT THE LOW RIGHT WING WAS ABOUT TO HIT TREES. HE SAID HE TRIED TO LEVEL THE AIRCRAFT BUT THE RIGHT WING STRUCK THE TREES AND THE ACFT CARTWHEELED INTO A DIRT ROAD.
