What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
During an aborted landing, the aircraft impacted a business hangar, , which was located approximately 1750 feet east of runway 18. The aircraft impacted the hangar on a heading of 180 degrees and came to rest on the roof of that structure at an approximate heading of 310 degrees. The right engine and propeller assembly were torn from the firewall and came to rest under the right wing. The left engine and propeller assembly, though damaged from the impact forces, remained intact. The accident aircraft, the business hangar, and an aircraft inside the business hangar, were all substantially damaged due to this event. There were no reported injuries to personnel working in the hangar at the time of the event. There were no visible signs of fuel in, on, or around the building that was impacted. The aircraft remained on the roof for approximately 21 hours before it could be removed by a crane operator/company. After the aircraft was removed, FAA inspectors determined all switches in the cockpit were secured in the off position, including the firewall fuel shut off valves. FAA inspectors performed a visual inspection of the fuel tanks which revealed the fuel tanks were not breached. Inspectors opened the fuel filler caps (6 total, and visibly inspected the amount of fuel in the fuel filler ports. The left wing had no visible fuel in any of the three filler ports. There was no visible fuel the right wing tip or the aux fuel tank ports . The right nacelle tank had trace amounts of what appeared to be fuel but not enough to measure. Ensuring the fuel drains were in the lowest position for each wing, the fuel tanks were drained. A total of approximately 3 oz of fuel was drained from the left wing and approximately 30 oz total was drained from the right wing.
As the FAA filed it
DURING AN ABORTED LANDING, THE AIRCRAFT IMPACTED A BUSINESS HANGAR, , WHICH WAS LOCATED APPROXIMATELY 1750 FEET EAST OF RUNWAY 18. THE AIRCRAFT IMPACTED THE HANGAR ON A HEADING OF 180 DEGREES AND CAME TO REST ON THE ROOF OF THAT STRUCTURE AT AN APPROXIMATE HEADING OF 310 DEGREES. THE RIGHT ENGINE AND PROPELLER ASSEMBLY WERE TORN FROM THE FIREWALL AND CAME TO REST UNDER THE RIGHT WING. THE LEFT ENGINE AND PROPELLER ASSEMBLY, THOUGH DAMAGED FROM THE IMPACT FORCES, REMAINED INTACT. THE ACCIDENT AIRCRAFT, THE BUSINESS HANGAR, AND AN AIRCRAFT INSIDE THE BUSINESS HANGAR, WERE ALL SUBSTANTIALLY DAMAGED DUE TO THIS EVENT. THERE WERE NO REPORTED INJURIES TO PERSONNEL WORKING IN THE HANGAR AT THE TIME OF THE EVENT. THERE WERE NO VISIBLE SIGNS OF FUEL IN, ON, OR AROUND THE BUILDING THAT WAS IMPACTED. THE AIRCRAFT REMAINED ON THE ROOF FOR APPROXIMATELY 21 HOURS BEFORE IT COULD BE REMOVED BY A CRANE OPERATOR/COMPANY. AFTER THE AIRCRAFT WAS REMOVED, FAA INSPECTORS DETERMINED ALL SWITCHES IN THE COCKPIT WERE SECURED IN THE OFF POSITION, INCLUDING THE FIREWALL FUEL SHUT OFF VALVES. FAA INSPECTORS PERFORMED A VISUAL INSPECTION OF THE FUEL TANKS WHICH REVEALED THE FUEL TANKS WERE NOT BREACHED. INSPECTORS OPENED THE FUEL FILLER CAPS (6 TOTAL, AND VISIBLY INSPECTED THE AMOUNT OF FUEL IN THE FUEL FILLER PORTS. THE LEFT WING HAD NO VISIBLE FUEL IN ANY OF THE THREE FILLER PORTS. THERE WAS NO VISIBLE FUEL THE RIGHT WING TIP OR THE AUX FUEL TANK PORTS . THE RIGHT NACELLE TANK HAD TRACE AMOUNTS OF WHAT APPEARED TO BE FUEL BUT NOT ENOUGH TO MEASURE.
