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.

On December 11, 2016 at approximately 1103 PST, a Beechcraft musketeer, N7998L,privacy data omitted, landed on runway 36 at Anacortes Airport, WA. This flight was being conducted under title 14 CFR part 91.

The pilot stated that a modest wind of no more than 10 KTS was blowing straight down the runway with no gust and visibility was 10 miles.

During the approach, pilot stated that he straighened his aircraft using the VASI glide path and slowed down to 70 mph by applying full flaps. As soon as he touched down he indicated that he raised the flaps and proceeded to roll out, during this time, he has not felt any vibrations or any discernible problems particularly on his landing gear.

Pilot stated that as he approached the main turn-off on the runway to the transient parking, he felt that the aircraft was slow enough to safely make a turn so he slightly turned the yoke to the right while simulteously stepping on his right brakes. But just as he stepped on his brakes he felt the aircraft sank to the left and the nose of the of the aircraft rose, at this time the pilot noticed that the aircraft is now skidding down the runway at approximately 20 degrees to the right off the centerline at the speed of approximately 30 mph. But all this time pilot indicated that the left wing did not appear to touch the ground, so he immediately took his feet off the brakes and pushed the yoke down hoping the aircraft would continue to roll down the runway and coast to a stop. Pilot noticed that the aircraft straightened momentarily but the nose never seemed to fall back, and almost immediately thereafter he felt the plane turn to the left of the runway onto the adjacent muddy grass apron. As the aircraft continue to swerve to the left, the left wing leading edge hit the airport landing counter box which could possibly caused the dangling left main landing gear held by the flexible hydraulic brake hose to completely separate from the aircraft. Left main landing gear rested approximately 40 feet from where the aircraft rested. Aircraft rested on the grassy apron facing northwest sustaining substantial damage.

As the FAA filed it

ON DECEMBER 11, 2016 AT APPROXIMATELY 1103 PST, A BEECHCRAFT MUSKETEER, N7998L,^PRIVACY DATA OMITTED^, LANDED ON RUNWAY 36 AT ANACORTES AIRPORT, WA. THIS FLIGHT WAS BEING CONDUCTED UNDER TITLE 14 CFR PART 91.

THE PILOT STATED THAT A MODEST WIND OF NO MORE THAN 10 KTS WAS BLOWING STRAIGHT DOWN THE RUNWAY WITH NO GUST AND VISIBILITY WAS 10 MILES.

DURING THE APPROACH, PILOT STATED THAT HE STRAIGHENED HIS AIRCRAFT USING THE VASI GLIDE PATH AND SLOWED DOWN TO 70 MPH BY APPLYING FULL FLAPS. AS SOON AS HE TOUCHED DOWN HE INDICATED THAT HE RAISED THE FLAPS AND PROCEEDED TO ROLL OUT, DURING THIS TIME, HE HAS NOT FELT ANY VIBRATIONS OR ANY DISCERNIBLE PROBLEMS PARTICULARLY ON HIS LANDING GEAR.

PILOT STATED THAT AS HE APPROACHED THE MAIN TURN-OFF ON THE RUNWAY TO THE TRANSIENT PARKING, HE FELT THAT THE AIRCRAFT WAS SLOW ENOUGH TO SAFELY MAKE A TURN SO HE SLIGHTLY TURNED THE YOKE TO THE RIGHT WHILE SIMULTEOUSLY STEPPING ON HIS RIGHT BRAKES. BUT JUST AS HE STEPPED ON HIS BRAKES HE FELT THE AIRCRAFT SANK TO THE LEFT AND THE NOSE OF THE OF THE AIRCRAFT ROSE, AT THIS TIME THE PILOT NOTICED THAT THE AIRCRAFT IS NOW SKIDDING DOWN THE RUNWAY AT APPROXIMATELY 20 DEGREES TO THE RIGHT OFF THE CENTERLINE AT THE SPEED OF APPROXIMATELY 30 MPH. BUT ALL THIS TIME PILOT INDICATED THAT THE LEFT WING DID NOT APPEAR TO TOUCH THE GROUND, SO HE IMMEDIATELY TOOK HIS FEET OFF THE BRAKES AND PUSHED THE YOKE DOWN HOPING THE AIRCRAFT WOULD CONTINUE TO ROLL DOWN THE RUNWAY AND COAST TO A STOP. PILOT NOTICED THAT THE AIRCRAFT STRAIGHTENED MOMENTARILY BUT THE NOSE NEVER SEEMED TO FALL BACK, AND ALMOST IMMEDIATELY THEREAFTER HE FELT THE PLANE TURN TO THE LEFT OF THE RUNWAY ONTO THE ADJACENT MUDDY GRASS APRON. AS THE AIRCRAFT CONTINUE TO SWERVE TO THE LEFT, THE LEFT WING LEADING EDGE HIT THE AIRPORT LANDING COUNTER BOX WHICH COULD POSSIBLY CAUSED THE DANGLING LEFT MAIN LANDING GEAR HELD BY THE FLEXIBLE HYDRAULIC BRAKE HOSE TO COMPLETELY SEPARATE FROM THE AIRCRAFT. LEFT MAIN LANDING GEAR RESTED APPROXIMATELY 40 FEET FROM WHERE THE AIRCRAFT RESTED. AIRCRAFT RESTED ON THE GRASSY APRON FACING NORTHWEST SUSTAINING SUBSTANTIAL DAMAGE.
