Which two aircraft certificates does rule 91.203 require to be on board?

The airworthiness certificate and the registration certificate.

  1. Engine logbook and weight and balance
  2. Airworthiness and registration certificates ✔
  3. Pilot logbook and medical certificate

Why: Rule 91.203(a) requires a current airworthiness certificate and an effective US registration certificate inside the aircraft. The airworthiness certificate must be displayed where passengers or crew can read it.

Huh, didn't know that: A US aircraft registration certificate expires seven years after the last day of the month it was issued.

The dad joke
Why did the airplane carry its registration? It wanted to be recognized.
