FAA enforcement actions

FAA enforcement records haven't been loaded into GroundCheck yet, so none can be shown — a gap in our data, not evidence of a clean enforcement history.

Maintenance disclosure history

Service Difficulty Reports are self-reported maintenance findings. The NUMBER of reports is not a measure of reliability — diligent operators file more, not fewer. These are shown for transparency, not as a negative signal.

1 report on file.
