From the FAA’s Accident/Incident Data System (AIDS), through its Aviation Safety Information Portal, as reported. The NTSB investigates accidents separately, and its record of an accident is the fuller one. The aircraft is matched to the registry by N-number and event date, checked against the reported make and model; the registry’s history has gaps, so older matches can be wrong. Compare the reported make and model.

What happened

The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.

Thepic departed foo enroute to F-46 on 11/27/2010 at about 15:30. At about 15:50 the engine sputtered. The engine switched from RH to LH tank and turned on the boost pump. The engine temporarily increased RPM prior loss o power. Turned on carb heat (humidity was low this date- 40%) turnd off fuel and electric power and prpared for an off runway landing . After passing power lines the aircraft right wing went up dramatically from a wind gust. (Weather indicated 8 know winds with little gusting) the aircraft impacted the ground nose wheel first. The aircraft landed in a slightly sideways position. This snapped off the nose wheel at impact. The aircraft r/h main gear impacted the ground next, collapsing. The l/h wing impacted the ground causing major strustural damage. The r/h wing also had wrinkling and oil canning. The aircraft was tipped, left wing high from the collapsed r/h main gear. On inspection the next day it was determined that there as no fuel in the l/h wing- upeer, and about 3 gallons in the r/h wing- lower. The r/h fuel tank was compromised. The pilot indicated that when he landed he checked both tanks, and fuel was present. As th valve was in the center position, it would allow fuel to transfer from the raised tank to the lower tank. The aircraft was taken to the owners mechanic where it was run. An on scene inspector noted that there was no fuel in the carburetor bowl or in the screen in the bottom of the electric fuel pump. This would indicate fuel starvation. The electric boost pump was intermittent and had to be tapped to keep running. The engine was started and ran normally.

THE ENGINE TEMPORARILY INCREASED RPM PRIOR LOSS O POWER. TURNED ON CARB HEAT (HUMIDITY WAS LOW THIS DATE- 40%) TURND OFF FUEL AND ELECTRIC POWER AND PRPARED FOR AN OFF RUNWAY LANDING . AFTER PASSING POWER LINES THE AIRCRAFT RIGHT WING WENT UP DRAMATICALLY FROM A WIND GUST. (WEATHER INDICATED 8 KNOW WINDS WITH LITTLE GUSTING) THE AIRCRAFT IMPACTED THE GROUND NOSE WHEEL FIRST. THE AIRCRAFT LANDED IN A SLIGHTLY SIDEWAYS POSITION. THIS SNAPPED OFF THE NOSE WHEEL AT IMPACT. THE AIRCRAFT R/H MAIN GEAR IMPACTED THE GROUND NEXT, COLLAPSING. THE L/H WING IMPACTED THE GROUND CAUSING MAJOR STRUSTURAL DAMAGE. THE R/H WING ALSO HAD WRINKLING AND OIL CANNING. THE AIRCRAFT WAS TIPPED, LEFT WING HIGH FROM THE COLLAPSED R/H MAIN GEAR.ON INSPECTION THE NEXT DAY IT WAS DETERMINED THAT THERE AS NO FUEL IN THE L/H WING- UPEER, AND ABOUT 3 GALLONS IN THE R/H WING- LOWER. THE R/H FUEL TANK WAS COMPROMISED. THE PILOT INDICATED THAT WHEN HE LANDED HE CHECKED BOTH TANKS, AND FUEL WAS PRESENT. AS TH VALVE WAS IN THE CENTER POSITION, IT WOULD ALLOW FUEL TO TRANSFER FROM THE RAISED TANK TO THE LOWER TANK.THE AIRCRAFT WAS TAKEN TO THE OWNERS MECHANIC WHERE IT WAS RUN. AN ON SCENE INSPECTOR NOTED THAT THERE WAS NO FUEL IN THE CARBURETOR BOWL OR IN THE SCREEN IN THE BOTTOM OF THE ELECTRIC FUEL PUMP. THIS WOULD INDICATE FUEL STARVATION. THE ELECTRIC BOOST PUMP WAS INTERMITTENT AND HAD TO BE TAPPED TO KEEP RUNNING. THE ENGINE WAS STARTED AND RAN NORMALLY.
