## Analysis

THE AIRCRAFT TOUCHED DOWN IN A 3-POINT LANDING ATTITUDE AT NORTH CANAAN, CONNECTICUT. THE LEFT LANDING GEAR WHEEL ROTATED 90 DEGREES AND THE LEFT GEAR WAS DRAGGED 144 YARDS BEFORE THE AIRCRAFT BECAME INVERTED. IT WAS REVEALED THAT THE BRAZE JOINT AT THE TOP OF THE INNER TUBE FAILED CAUSING THE STRUT TO EXTEND PAST THE FULL EXTENSION STOP ALLOWING THE WHEEL TO ROTATE. THE ONLY PART HOLDING THE WHEEL ASSEMBLY TO THE STRUT AT THIS POINT WAS THE FLEXIBLE BRAKE LINE.
