N817BT (525-0635) was operating from KSNA to KIWA on 2026-09-04. SkyMeter recorded a 7700 transponder transmission at 02:27 UTC. Code 7700 indicates a general emergency declaration (e.g. engine, medical, smoke). A sustained transmission is normally accompanied by ATC priority handling. Trace data at the event: 9413 ft AGL, 206 kt GS. Approach stability score: 49/100. 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 13 kt wind, 12 kt crosswind component. Detection algorithm and known limitations: see SkyMeter methodology.

SkyMeter cross-referenced this flight against FAA-published TFRs that were active during its window and within its geographic bounding box. Overlap doesn't necessarily mean violation — the aircraft may have been outside the TFR’s precise polygon or flying under air-traffic-control coordination.

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.
