Self-Endorsement Prohibition

FAR 61.421 Self-Endorsement Prohibition

FAR 61.421 prohibits flight instructors with a sport pilot rating from giving themselves any endorsement required under Part 61. Learn what this means.

In Plain English

FAR 61.421 answers a simple but important question: if you're a flight instructor with a sport pilot rating (CFI-S), can you sign off your own endorsements? The answer is no — never.

The rule prohibits you from endorsing yourself for any of the following required under Part 61:

  • A certificate or rating
  • A privilege (such as a new aircraft category or class)
  • A flight review
  • An authorization
  • A practical test (checkride)
  • A knowledge test
  • A proficiency check

Why it matters operationally: endorsements exist to confirm that a qualified, independent instructor has evaluated your skills and readiness. Allowing self-endorsements would defeat that safety check. If you're a CFI-S who needs an endorsement — for example, to take a flight review or add a privilege — you must seek out another authorized instructor to evaluate you and provide the logbook signature. This keeps the training and testing system honest and ensures every pilot meets an objective standard before exercising new privileges.
