What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
On February 4, 2016, N48637 a Cessna 152 (tach time 7121.5, 36.2 hours after the last 100 hr inspection) was involved in an off airport landing due to an engine failure in flight, and the flight instructors subsequent inability to restart the engine in flight. No damages to the aircraft or any crew injuries were sustained in the emergency landing. The fuel system contained an adequate supply of fuel, and all airframe sumps, drains and the strainer were found free of contaminates. The carburetor bowl was found to be free of contaminates as well. Further on site investigation revealed multiple engine maintenance issues. The engine would not start or even fire at all, after multiple starting attempts at the scene. All fuel primer lines were loose at the nozzle connections and at the distribution tee, causing fuel to be sprayed and drip within the cowling, (a fire hazard). All 4 lower spark plugs electrodes were found to be completely covered and fouled with lead clinker deposits. The upper 4 spark plugs electrodes were lead fouled as well, and externally were completely rust covered. Mechanic replaced all 8 spark plugs with new, and the engine started an ran up to full power satisfactorily. The oil cooler mounting hardware was found loose at all 4 mounting points.
