  1. A designated pilot examiner
  2. An FAA aviation safety inspector
  3. An authorized instructor ✔

Why: The instructor must have taught the ground training or reviewed your home study on the knowledge areas in 61.125, then certify you are prepared for the test. A second endorsement is needed before the practical test.

Huh, didn't know that: Knowledge areas include NTSB accident reporting rules and aeronautical decision making.

The dad joke
Why did the student bring a pencil to the endorsement? Everything had to be signed off.
