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

No maintenance difficulty reports on file. Note: SDR filing is largely voluntary, so absence is not evidence of a clean maintenance history.
