Synopsis
Light transport jet flight crew reported runway excursion during landing due to gusty winds. Flight crew shut down aircraft and exited.
Narrative
Uneventful flight and approach into ZZZ. We grabbed ASOS roughly 50 miles out; which we reviewed wind as 250 @ 13. Before being released to CTAF; Center mentioned bird activity but no other remarks for ZZZ. I made a 12 mile position report for [Runway] XX; and a 5 mile position report. Wind appeared calm; and the clouds were 8000 when we broke out. After discussion with the Captain; and landing was assured; we agreed to cancel IFR in air and continue in VFR conditions. The Captain was stable at 1000 ft and 500 ft. Airspeed was on V APP and touched down initially in touchdown zone and on V REF speed. Before the front wheel could come to ground; we experienced a heavy gust that caused the plane to balloon up and down the runway. Captain had wings level; idle thrust; and did his best to maintain directional control; but was unable to get the plane back on wheels for a momentary period. After recovering from the unexpected weather event and with wheels on ground; Captain called for ground flaps. I recall noticing our indicated airspeed didn't decrease nearly at all after ground flaps were put in. I called out remaining runway distance as the Captain applied full brake pressure. We rolled on centerline; off the runway. After exiting the aircraft; we could feel the wind swirling aggressively around in every direction. In my professional opinion; I determined the unexpected weather event was wind shear that caused the balloon after landing. It was the safest course of action to maintain centerline and continue to landing. Cause: Wind shear.
Second reporter narrative
After breaking out of the clouds and making visual contact with the runway and landing was assured; the First Officer called ZZZ Approach and canceled our IFR flight plan. We continued in VFR conditions to Runway XX. The ASOS reported winds 250 @ 13. The approach was stable and touchdown was at V ref in the touchdown zone. Shortly after touchdown; a significant wind event caused the aircraft to balloon even though main gear struts had compressed and the nose was coming down. I did everything I could to maintain directional control. The aircraft floated a considerable distance with the throttles at idle before touching down a second time. I considered a rejected landing but considering the wind shear I decided in my best judgment the safest course of action was to stop straight ahead. I called for ground flaps; and applied maximum brake pressure. The First Officer was calling runway remaining. I maintained directional control on the runway centerline; but ran out of available runway. After accomplishing the Shutdown Checklist; we exited the airplane into gusty winds. Ten minutes after landing; ASOS winds were reported out of the south at 10 gusting to 43 knots with light rain.Cause: Wind shear
