## Narrative

As the FAA filed it, in capitals; the FAA replaces private details with ^PRIVACY DATA OMITTED^.

ON MAY 5, 2020 AT APPROX. 1033 HOURS LOCAL, N22ST DEPARTED THE END OF RUNWAY 36 AT 3J1 AIRPORT. AFTER AN APPARENTLY UNEVENTFUL APPROACH, N22ST TOUCHED DOWN AND APPEARED TO FAIL TO DEPLOY SPOILERS, THUS GREATLY REDUCING BREAKING EFFECTIVITY. THE AIRCRAFT DEPARTED THE END OF THE RUNWAY, COMING TO REST IN A SWAMPY AREA APPROX. 400 FEET PAST THE END OF THE RUNWAY. NO INJURIES WERE SUSTAINED DURING THE RUNWAY EXCURSION. DAMAGE TO AC WAS SUBSTANTIAL ACCORDING TO GULFSTREAM REPRESENTATIVES WHO WERE ON LOCATION. RIGHT MAIN GEAR AND NOSE GEAR RIPPED OFF, WITH FLAP DAMAGE, LEADING EDGE AND SLAT DAMAGE, NOSE CONE DAMAGE, AND A FLOODED AVIONICS BAY.

GULFSTREAM SUBSEQUENTLY DID A SYSTEMS ANALYSIS AND FOUND A POTENTIAL THOUGH UNLIKELY PROBLEM WITH THE GROUND AIRBRAKE SWITCH SYSTEM THAT COULD POSSIBLY CONTRIBUTE TO DECREASED RUNWAY PERFORMANCE: "BASED ON THIS INFORMATION WE CANNOT CONCLUSIVELY CONFIRM IF THE SWITCH RESISTANCE WAS HIGH DURING THE EVENT OR A MANIFESTATION POST INCIDENT" BASED ON THIS, IT CANNOT CONCLUSIVELY BE STATED THAT PILOT ERROR WAS A FACTOR.

## The NTSB's investigation of this event (1)

From the NTSB's public API. Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model.

Probable cause: The flight crew’s continuation of an unstable approach and the failure of the ground air brakes to deploy upon touchdown, both of which resulted in the runway overrun. Contributing was the crew’s…
