NTSB Narrative Summary Released at Completion of Accident

THE ULTRALIGHT ENGINE LOST POWER WHILE THE PLT WAS IN A PRACTICE AREA. HE RETURNED TO THE ARPT, AND DURING THE ATTEMPT TO LAND, THE ACFT CRAHSED. AN INSTRUCTOR SAID THE ACFT SEEMED TO BE FLYING SLOWER THAN NORMAL AND THE PLT EXTENDED THE DOWNWIND TURN TO BASE LEG MORE THAN NORMAL. THE ACFT CRASHED ABOUT HALF A MILE FROM THE ARPT. THE CONTROL STICK WAS JAMMED IN THE FULL NOSE UP POSITION. THIS PARTICULAR ACFT WAS NOSE HEAVY BECAUSE OF THE INSTALLATION OF A LARGER ENGINE.AN EXAM OF THE ENGINE REVEALED THAT ONE OF THE TWO SPARK PLUG LEADS WAS LOOSE, ALLOWING MINIMAL CONTACT BETWEEN THE LEAD & THE SPARK PLUG.
