THE COURSE HAS 3 GROUND SCARS CONSISTENT WITH 3 LANDING GEAR MAKING CONTACT WITH THE TURF. FOLLOWED BY 3 DEEPER GROUND SCARS CONSISTENT WITH THE FUSELAGE AND ENGINES IMPACTING THE TURF. SEVERAL TREES HAVE SCARS CONSISTENT WITH THE WINGS IMPACTING THE TREES AND WING DEBRIS NEARBY. THE GROUND ON THE LEFT HAS A DEEP SCAR WITH THE IMPRINT OF THE BACKSIDE OF THE PROP SHAFT. THE LEFT PROP WAS FOUND NEARBY. THE TREES ON THE RIGHT HAVE SCARS CONSISTENT WITH THE RIGHT WING IMPACT AND RIGHT WING PIECE FOUND NEARBY. THE GROUND SCARS CONTINUED ON THE TURF TO APPROXIMATELY 400 TO 700 YARDS FURTHER DOWN TO THE LOCATION OF THE AIRCRAFT. SEVERAL TREES WERE IMPACTED ALONG THE WAY. THE WINGS OUTBOARD OF THE NACELLE’S DEPARTED THE AIRCRAFT, THE LEFT PROP AND THE 3 LANDING GEAR. THE FUSELAGE WAS INTACT AND HAS MANY DENTS AND TEARS.
