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.

The airman reported that he and a passenger had topped off the aircraft with fuel prior to departing slidell, LA (asd) on an IFR flight plan at 1300 local and flew to destin, FL (dts) and picked up one passenger in destin and departed on an IFR flight plan for vidalia, LA (0R4) at 1500 local. One passenger was dropped-off at vidalia; they then departed VFR for slidell at 1715 local. Approximately 25-30 minutes later while cruising at 2500 MSL the plane lost power on the left hand engine. The plane then lost 1000 feet of altitude; he elected to continue to his destination of slidell on one engine. Approximately 10 minutes later while cruising at 1500 MSL, the plane lost power in the right hand engine and the pilot picked out an open field to land in. The plane had an uneventful touch-down in an open field. Upon roll-out, the plane struck a tree with the left hand wing and the wingtip and LH aileron was ripped away causing substantial damage to the LH wing.

During the on-site, post-accident inspection of the aircraft by FAA safety inspectors; the fuel gauges indicated there zero fuel in any of the tanks, no damage to the fuel tanks, no evidence of leaking fuel, and no anomalies of the airframe, engines, or systems to hinder normal operation. While checking for fuel contaminants, the stream of fuel from the sumps was slow. No water or other contaminants were observed in the sumped fuel. Upon recovery, the salvage team reported to inspectors that prior to removal of the wings for ground transport, that the most fuel drained from any one tank was half-a-gallon.

It should also be noted that although the pilot reported to inspectors that he had feathered the LH propeller after its failure, inspectors found the propeller to be in the normal position. Additionally; both throttles, prop controls, and mixture levers were in the normal position for a normal landing and shut down.

As the FAA filed it

THE AIRMAN REPORTED THAT HE AND A PASSENGER HAD TOPPED OFF THE AIRCRAFT WITH FUEL PRIOR TO DEPARTING SLIDELL, LA (ASD) ON AN IFR FLIGHT PLAN AT 1300 LOCAL AND FLEW TO DESTIN, FL (DTS) AND PICKED UP ONE PASSENGER IN DESTIN AND DEPARTED ON AN IFR FLIGHT PLAN FOR VIDALIA, LA (0R4) AT 1500 LOCAL. ONE PASSENGER WAS DROPPED-OFF AT VIDALIA; THEY THEN DEPARTED VFR FOR SLIDELL AT 1715 LOCAL. APPROXIMATELY 25-30 MINUTES LATER WHILE CRUISING AT 2500 MSL THE PLANE LOST POWER ON THE LEFT HAND ENGINE. THE PLANE THEN LOST 1000 FEET OF ALTITUDE; HE ELECTED TO CONTINUE TO HIS DESTINATION OF SLIDELL ON ONE ENGINE. APPROXIMATELY 10 MINUTES LATER WHILE CRUISING AT 1500 MSL, THE PLANE LOST POWER IN THE RIGHT HAND ENGINE AND THE PILOT PICKED OUT AN OPEN FIELD TO LAND IN. THE PLANE HAD AN UNEVENTFUL TOUCH-DOWN IN AN OPEN FIELD. UPON ROLL-OUT, THE PLANE STRUCK A TREE WITH THE LEFT HAND WING AND THE WINGTIP AND LH AILERON WAS RIPPED AWAY CAUSING SUBSTANTIAL DAMAGE TO THE LH WING.

DURING THE ON-SITE, POST-ACCIDENT INSPECTION OF THE AIRCRAFT BY FAA SAFETY INSPECTORS; THE FUEL GAUGES INDICATED THERE ZERO FUEL IN ANY OF THE TANKS, NO DAMAGE TO THE FUEL TANKS, NO EVIDENCE OF LEAKING FUEL, AND NO ANOMALIES OF THE AIRFRAME, ENGINES, OR SYSTEMS TO HINDER NORMAL OPERATION. WHILE CHECKING FOR FUEL CONTAMINANTS, THE STREAM OF FUEL FROM THE SUMPS WAS SLOW. NO WATER OR OTHER CONTAMINANTS WERE OBSERVED IN THE SUMPED FUEL. UPON RECOVERY, THE SALVAGE TEAM REPORTED TO INSPECTORS THAT PRIOR TO REMOVAL OF THE WINGS FOR GROUND TRANSPORT, THAT THE MOST FUEL DRAINED FROM ANY ONE TANK WAS HALF-A-GALLON.

IT SHOULD ALSO BE NOTED THAT ALTHOUGH THE PILOT REPORTED TO INSPECTORS THAT HE HAD FEATHERED THE LH PROPELLER AFTER ITS FAILURE, INSPECTORS FOUND THE PROPELLER TO BE IN THE NORMAL POSITION. ADDITIONALLY; BOTH THROTTLES, PROP CONTROLS, AND MIXTURE LEVERS WERE IN THE NORMAL POSITION FOR A NORMAL LANDING AND SHUT DOWN.
