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.

N520NE encountered deep snow on the runway surface at Canyonlands Field Airport, Moab Utah. Aerolynx was the operator of the aircraft. Instrument meteorologial conditions prevailed, and a company flight plan had been filed. The pilot reported that prior to departure he received the latest weather report via the internet. He taxied to runway 21 and preformed the appropriate pre takeoff procedures, which included the lastest weather from ASOS. He noted that the runway had a thin snow covering and light show continued to fall. During the takeoff roll, he observed that about 1/4 down the runway the snow was deeper than it had been at the depature. He additionally noticed a large snow bank (windrow) was perpendicular to the runway, stretching across its entire width. The airplane collided with the perpendicular snow, resulting in a loss of foward momentum and veering tendency to the left of the runway centerline. The pilot attempted to correct but was unable to bring the aircraft back to the centerline. At that point the pilot made the determination to abort the takeoff. The airplane came to rest on the snow covered ground left of the runway, with its nose pointed about 90 degrees from the runway heading. Weather at 1653 (7 minutes prior to the accident) stated: 0.75 miles,; 1,500 foot overcast, with few clouds at 800 feet; light snow and mist; temperature 23 degrees fahrenheit; dew point 20 degrees fahrenheit; and altimeter 29.62" hg. At 1723, the report was updated toreflect visibility had increased to 1.5 miles with the overcast layer at 2,200 feet and broken clouds at 1,500 feet.

As the FAA filed it

N520NE ENCOUNTERED DEEP SNOW ON THE RUNWAY SURFACE AT CANYONLANDS FIELD AIRPORT, MOAB UTAH. AEROLYNX WAS THE OPERATOR OF THE AIRCRAFT. INSTRUMENT METEOROLOGIAL CONDITIONS PREVAILED, AND A COMPANY FLIGHT PLAN HAD BEEN FILED. THE PILOT REPORTED THAT PRIOR TO DEPARTURE HE RECEIVED THE LATEST WEATHER REPORT VIA THE INTERNET. HE TAXIED TO RUNWAY 21 AND PREFORMED THE APPROPRIATE PRE TAKEOFF PROCEDURES, WHICH INCLUDED THE LASTEST WEATHER FROM ASOS. HE NOTED THAT THE RUNWAY HAD A THIN SNOW COVERING AND LIGHT SHOW CONTINUED TO FALL. DURING THE TAKEOFF ROLL, HE OBSERVED THAT ABOUT 1/4 DOWN THE RUNWAY THE SNOW WAS DEEPER THAN IT HAD BEEN AT THE DEPATURE. HE ADDITIONALLY NOTICED A LARGE SNOW BANK (WINDROW) WAS PERPENDICULAR TO THE RUNWAY, STRETCHING ACROSS ITS ENTIRE WIDTH. THE AIRPLANE COLLIDED WITH THE PERPENDICULAR SNOW, RESULTING IN A LOSS OF FOWARD MOMENTUM AND VEERING TENDENCY TO THE LEFT OF THE RUNWAY CENTERLINE. THE PILOT ATTEMPTED TO CORRECT BUT WAS UNABLE TO BRING THE AIRCRAFT BACK TO THE CENTERLINE. AT THAT POINT THE PILOT MADE THE DETERMINATION TO ABORT THE TAKEOFF. THE AIRPLANE CAME TO REST ON THE SNOW COVERED GROUND LEFT OF THE RUNWAY, WITH ITS NOSE POINTED ABOUT 90 DEGREES FROM THE RUNWAY HEADING. WEATHER AT 1653 (7 MINUTES PRIOR TO THE ACCIDENT) STATED: 0.75 MILES,; 1,500 FOOT OVERCAST, WITH FEW CLOUDS AT 800 FEET; LIGHT SNOW AND MIST; TEMPERATURE 23 DEGREES FAHRENHEIT; DEW POINT 20 DEGREES FAHRENHEIT; AND ALTIMETER 29.62" HG. AT 1723, THE REPORT WAS UPDATED TOREFLECT VISIBILITY HAD INCREASED TO 1.5 MILES WITH THE OVERCAST LAYER AT 2,200 FEET AND BROKEN CLOUDS AT 1,500 FEET.
