## Analysis

THE PLT STATED THE ENG QUIT AT ABOUT 100-200 FT AGL AFTER TAKEOFF. HE EXECUTED A DESCENDING RIGHT TURN TO REMAIN WITHIN THE ARPT BOUNDARY & THE ACFT STRUCK THE GROUND. THE UPPER PORTION OF THE MAGNETO MOUNT FLANGE WAS BROKEN & THE MAGNETO WAS HANGING BY THE IGNITION WIRES. THE MAGNETO UPPER FLANGE HAD A RECTANGULAR WEAR PATTERN CORRESPONDING TO THE MOUNT BLOCK ABOUT 1/8 INCH DEEP. THE FLANGE HAD CRACKED AWAY AT THAT POINT. THE LOWER MOUNT BLOCK & NUT WERE MISSING. IT APPEARED THAT EITHER THE BOTTOM NUT WAS LEFT OFF OR HAD VIBRATED OFF.
