Long landing rollout — N4221S

N4221S (TRI Rotor Spray & Chemical) was operating from K0G3 to KAHQ on 2026-07-17. SkyMeter detected a long landing rollout at Wahoo Municipal Airport (KAHQ) on runway 20 at 20:07 UTC. Trace data at the event: 1220 ft AGL, 4 kt GS. Approach stability score: 32/100. Scores below 50 occur on under 10% of approaches at this runway and indicate the v2 scorer flagged the approach as highly anomalous (three or more gates exceeded the runway's P90 envelope simultaneously). METAR at the time reported 9 kt wind, 2 kt crosswind component, 16,093 m visibility. A long landing rollout is detected when ground deceleration after touchdown is below the per-runway P10 envelope. It is an observational measure of rollout efficiency, not a runway-exit incident. Detection algorithm and known limitations: see SkyMeter methodology.

Automated analysis. Events shown on this page (such as go-around, unstable approach, or runway events) are heuristic classifications produced by algorithms from publicly broadcast ADS-B data. They are intended to surface flights of interest for further review — they are not findings of fact, and they do not determine pilot fault, regulatory compliance, or the cause of any occurrence. Coverage gaps and sensor noise can affect accuracy. Only the relevant civil aviation authority or accident investigation body can make official determinations.
