THE AIRCRAFT PASSED THROUGH THE TOPS OF TREES APPROXIMATELY 150 FEET BEYOND, AND ENTERED A STALL/SPIN MANEUVER, IMPACTING A POWER LINE AND THE GROUND APPROXIMATELY 2,800 FEET SHORT OF THE RUNWAY THRESHOLD. THE FLAPS AND LANDING GEAR WERE IN A RETRACTED POSITION. POST-CRASH EXAMINATION REVEALED THE CRANKSHAFT SEPARATED IN FATIGUE WHICH ORIGINATED FROM A CIRCUMFERENTIAL GOUGE MARK ON THE AFT FACE OF THE #2 CHEEK AT AN AREA LOCATED OUTBOARD OF THE FORWARD RADIUS OF THE #1 ROD JOURNAL.
