The NTSB's narrative final · quoted from the NTSB record
THE PILOT STATED THAT DURING CRUISE FLIGHT AT 5,000 FEET ABOUT AN HOUR AFTER DEPARTURE, THE ENGINE EXPERIENCED A LOSS OF POWER. MOMENTARY APPLICATION OF CARBURETOR HEAT RESTORED ENGINE POWER BUT THE ENGINE AGAIN FAILED. DURING THE FORCED LANDING THE AIRPLANE COLLIDED WITH TREES. EXAMINATION OF THE ENGINE REVEALED CRANKSHAFT, CAMSHAFT, AND VALVE TRAIN CONTINUITY. DIFFERENTIAL COMPRESSION OF ALL CYLINDERS USING 80 PSI AS A BASE REVEALED NUMBERS GREATER THAN 70 PSI. EACH MAGNETO TO ENGINE TIMING WAS DETERMINED TO BE CORRECT AND THE MAGNETOS WERE REMOVED FOR BENCH TESTING WHICH REVEALED THAT THE RIGHT MAGNETO WAS OPERATING NORMALLY. THE LEFT MAGNETO WAS FOUND TO BE FIRING INTERMITTENTLY DUE TO PARTIAL FAILURE OF THE IGNITION COIL. EXAMINATION OF THE FUEL VENT SYSTEM REVEALED THAT A VENTED FUEL CAP WAS FOUND SECURED BY CHAIN TO THE LEFT FUEL TANK FILLER PORT AND A NON- VENTED FUEL CAP WAS SECURED BY CHAIN TO THE RIGHT FUEL TANK PORT. THE CORRECT POSITIONS FOR VENTED AND NON-VENTED FUEL CAPS IS OPPOSITE FROM THE POSITIONS IN WHICH THEY WERE FOUND. ADDITIONALLY, A MALFUNCTION OF THE VENT VALVE ASSEMBLY WAS NOTED. THE VENT VALVE ASSEMBLY WAS NOT REMOVED FOR EXAMINATION. THE AIRPLANE HAD ACCUMULATED ABOUT 3.9 HOURS SINCE AN ANNUAL INSPECTION WAS PERFORMED ON APRIL 6, 1995.

About this page
Everything above comes from the NTSB's public accident database: the narrative, probable cause and findings are the NTSB's own words, and the coded tables behind its report (pilot, aircraft, flight, weather, injuries, sequence of events) are written out in plain English. Pilots' ages, home towns and medical details are left out on purpose. The documents and photographs are the NTSB's docket, the folder of records gathered during the investigation, shown as the NTSB released them (the NTSB redacts some personal details first) and listed under the NTSB's own titles. This site's own text never names pilots, passengers or anyone else involved. A preliminary report describes what is known soon after the event and can change; the final report, with the probable cause, usually follows one to two years later and this page is refreshed when it does. Case number MIA95LA165.
