THE AIRCRAFT WAS FOUND UPRIGHT IN ON A 320 DEGREES HEADING WITH ALL COMPONENTS PRESENT WITHIN THE ACCIDENT AREA. THE PROPELLER HAD 2 BLADES HIDDEN FROM VIEW WITH ONE REMAINING BLADE SHOWING LEADING EDGE DEFORMITY INDICATIVE OF BEING UNDER POWER ON IMPACT. ALL THREE BLADES REMAINED ATTACHED TO THE PROPELLER HUB. THE PROPELLER GOVERNOR WAS FOUND FRACTURED DUE TO IMPACT FORCES. THE ENGINE AND HOPPER SECTION OF THE AIRCRAFT WERE FOUND HIGHLY FRAGMENTED AND COVERED IN FUNGICIDE. THE ENGINE WAS BROKEN IN TWO AT THE TURBINE BLADE SECTION. ALL MOTOR MOUNTS AND BRACING WERE BROKEN FORWARD OF THE COCKPIT. THE COCKPIT AREA SHOWED BREACHING AT THE WINDSHIELD DUE TO FUSELAGE TWISTING ON IMPACT. THE COCKPIT FLOOR WAS CRUSHED AND MOVED UPWARD INTO THE CREW AREA. THE INSTRUMENT PANEL REMAINED RELATIVELY INTACT. THE FUSELAGE SHOWED SIGNS OF LEFT SIDE COMPRESSION AND TWISTING. BOTH WINGS SHOWED LEADING EDGE CRUSHING AND DEFORMITY OF APPROXIMATELY 45-DEGREE NOSE DOWN IMPACT. BOTH AILERONS WERE DAMAGED BY IMPACT FORCES WITH FLAPS SHOWING APPROXIMATELY 10 DEGREES OF DEPLOYMENT AT TIME OF IMPACT. BOTH MAIN LANDING GEAR WERE HIDDEN FROM VIEW AND FOLDED UNDER THE WINGS. CONTROL CONTINUITY COULD NOT BE ESTABLISHED AT THE TIME OF INVESTIGATION DUE TO EXTENSIVE FLOOR AND FLIGHT CONTROL DAMAGE.

Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model. - [NTSB CEN18FA339](https://openairdocs.org/ntsb/CEN18FA339), Aug 18, 2018: Air Tractor AT502 (N502RL), Bronson, MI, destroyed, 1 fatal. Probable cause: The pilot's failure to maintain airspeed while maneuvering, which resulted in exceedance of the airplane's critical angle of attack, an aerodynamic stall, and loss of control at an altitude too low… From the FAA Accident/Incident Data System.
