The NTSB's narrative final · quoted from the NTSB record
ABOUT 30 MIN AFTER TAKEOFF, THE ENGINE LOST POWER AT ABOUT 1000 FT AGL WHEN THE PILOT ADDED POWER TO CLIMB. HE WAS UNABLE TO RESTART THE ENGINE AND ELECTED TO LAND ALONG THE SHORELINE. DURING THE APPROACH, THE AIRCRAFT COLLIDED WITH POWER LINES. REPORTEDLY, THE PILOT THEN STALLED THE PLANE WHILE AVOIDING A HOUSE, THE AIRCRAFT DROPPED INTO A MARSH AND IT SLIDE ABOUT 100 FT BEFORE COMING TO A STOP. AN OPERATIONAL CHECK OF THE ENGINE REVEALED THAT THE SLEET DUCT BETWEEN THE CARBURETOR AND CARBURETOR AIRBOX WAS WORN. ABOVE 1200 TO 1500 RPM, THE DUCT WOULD COLLAPSE AND THE ENGINE WOULD QUIT.
