## Analysis

A PASSENGER IN THE ACFT REPORTED THE PLT MADE MORE THAN ONE PASS OVER 'A SALT LICK', EACH TIME COMING CLOSER AND CLOSER TO THE TREES. ON THE LAST PASS THE ACFT 'JUST FELL OUT OF THE SKY', HIT THE TREES, AND LANDED UPSIDE DOWN. FIRE BROKE OUT ALMOST IMMEDIATELY WHILE THE TWO PASSENGERS AND PLT WERE STILL IN THE BURNING ACFT. THE PLT AND TWO PASSENGERS ALL RECEIVED SEVERE BURNS BEFORE GETTING OUT.THE ACFT WAS DESTROYED. ONE BURN VICTIM LATER DIED.
