N.C. Gen. Stat. § 76A-43

In consideration that a mutual association for pilots has been formed, is operational and is expedient for effective management, the Commission shall recognize such a proper pilot association formed for the smooth business transactions in the provision of services. However, the Commission may prescribe such reasonable rules and regulations for the governance of such associations in its direct relationship with the Commission as it deems necessary. Any licensed pilot refusing to become a member of such association shall be subject to suspension or have his license revoked, at the discretion of the Commission.
