## Analysis

PLT SAID HE WAS FLYING LOW AND CHASING BLACK BIRDS FROM HIS SUNFLOWER FIELDS. TERRAIN WAS ROLLING HILLS. PLT SAID HE MADE ONE PASS OVER FIELD AND WAS TURNING AROUND FOR ANOTHER PASS. 'I GOT MY AIRSPEED TOO LOW AND STARTED TO STALL. I BROUGHT IT OUT OF THE STALL BUT DIDN'T HAVE ENOUGH ALTITUDE TO REGAIN AIRSPEED.' ACCORDING TO AN FAA SPOKESMAN, A PLT MUST EITHER POSSESS AN AGRICULTURAL OPERATOR CERTIFICATE ISSUED UNDER 14 CFR 137 OR OBTAIN A CERTIFICATE OF AUTHORIZATION (FAA FORM 7711-1) OR WAIVER IN ORDER TO CONDUCT LOW LEVEL FLYING OR 'BIRD CHASING.' PLT DID NOT POSSESS EITHER CERTIFICATE.
