What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
Aircraft landed on top of a building, partially through the roof. (-4)the pilot said the airplane was difficult to start after numerous fuel priming actions and two start attempts. It started on the third attempt after using what he described as a flooded engine start. Ten minutes after takeoff the engine sputtered and RPM dropped to 1,500. The pilot applied carburetor heat, chose alternate magneto positions, turned on the electric fuel pump, and adjusted the mixture to no avail. He said the power fluctuated before the engine lost all its power. A witness observed a fluid coming from the airplane as it flew overhead. The fluid landed on his windshield and evaporated. During the forced landing, the airplane impacted the roof of an abandoned two-story building. The engine, fuel, and ignition systems examination revealed no anomalies that would prevent power production. Soot and carbon-like deposits were on the carburetor's venturi and spark plugs. A carburetor icing probability chart showed carburetor icing was not probable.
As the FAA filed it
AIRCRAFT LANDED ON TOP OF A BUILDING, PARTIALLY THROUGH THE ROOF. (-4)THE PILOT SAID THE AIRPLANE WAS DIFFICULT TO START AFTER NUMEROUS FUEL PRIMING ACTIONS AND TWO START ATTEMPTS. IT STARTED ON THE THIRD ATTEMPT AFTER USING WHAT HE DESCRIBED AS A FLOODED ENGINE START. TEN MINUTES AFTER TAKEOFF THE ENGINE SPUTTERED AND RPM DROPPED TO 1,500. THE PILOT APPLIED CARBURETOR HEAT, CHOSE ALTERNATE MAGNETO POSITIONS, TURNED ON THE ELECTRIC FUEL PUMP, AND ADJUSTED THE MIXTURE TO NO AVAIL. HE SAID THE POWER FLUCTUATED BEFORE THE ENGINE LOST ALL ITS POWER. A WITNESS OBSERVED A FLUID COMING FROM THE AIRPLANE AS IT FLEW OVERHEAD. THE FLUID LANDED ON HIS WINDSHIELD AND EVAPORATED. DURING THE FORCED LANDING, THE AIRPLANE IMPACTED THE ROOF OF AN ABANDONED TWO-STORY BUILDING. THE ENGINE, FUEL, AND IGNITION SYSTEMS EXAMINATION REVEALED NO ANOMALIES THAT WOULD PREVENT POWER PRODUCTION. SOOT AND CARBON-LIKE DEPOSITS WERE ON THE CARBURETOR'S VENTURI AND SPARK PLUGS. A CARBURETOR ICING PROBABILITY CHART SHOWED CARBURETOR ICING WAS NOT PROBABLE.
