FAR 61.403 — Sport Pilot CFI Eligibility
FAR 61.403 sets the age, English language, and pilot certificate requirements to qualify for a flight instructor certificate with a sport pilot rating.
FAR 61.403 lists the basic eligibility requirements you must meet before you can earn a flight instructor certificate with a sport pilot rating (often called a CFI-S). These are the gateway requirements — you'll need to satisfy them before any training, knowledge test, or practical test counts toward the rating.
To be eligible, you must:
- Be at least 18 years old.
- Be able to read, speak, write, and understand English. If a medical condition prevents this, the FAA may issue your certificate with operating limitations as needed for safety.
- Hold at least a sport pilot certificate with the category and class ratings or privileges appropriate to the flight instructor privileges you're seeking.
Why it matters operationally: as a CFI-S, you'll be giving instruction and signing off student pilots, so the FAA requires you already have demonstrated competence in the same category and class you intend to teach. The English requirement ensures you can communicate effectively with students, ATC, and other pilots — a safety-critical skill in any instructional environment.
