Under what condition is a holder of a commercial pilot certificate restricted from operating under BasicMed?

A holder of a commercial pilot certificate is restricted from operating under BasicMed at any time because BasicMed is designed for private pilots and does not apply to commercial operations. This means that commercial pilots are required to hold a valid medical certificate, typically a second-class or first-class certificate, depending on the type of operation they are conducting.

The BasicMed regulations allow private pilots to fly without a medical certificate as long as they meet specific requirements, such as having a state-issued driver's license and completing a medical self-assessment. However, since the commercial pilot certificate encompasses more advanced privileges and responsibilities, it necessitates adherence to the more stringent medical standards set forth by the FAA. Thus, regardless of the situation—whether flying solo, at night, or even when carrying passengers for hire—a commercial pilot cannot operate under BasicMed.
