Narrative:
DURING A FORCED LANDING DUE TO LOSS OF ENGINE POWER THE AIRPLANE STRUCK A TREE WITH THE RIGHT WING. FOLLOWING THE TREE STRIKE THE AIRPLANE YAWED AND SLOWED DOWN. INITIAL GROUND CONTACT WAS WITH THE RIGHT WING, THIS CAUSED THE AIRPLANE TO ROTATE CLOCKWISE, RESULTING IN THE LANDING GEAR COLLAPSING. AN INSPECTION OF THE AIRPLANE REVEALED THAT THE NUMBER 1 CYLINDER HAD FAILED AND SEPARATED FROM THE ENGINE.
