Where is the FAA registration number located on an aircraft?

The FAA registration number, also known as the N-number, is located on both sides of the fuselage near the tail of the aircraft. This placement is important for visibility and identification purposes, as it allows for easy recognition from the ground or from other aircraft. The registration number serves as a unique identifier for each aircraft, enabling authorities and agencies to track ownership, maintenance history, and compliance with aviation regulations.

Being situated near the tail facilitates quick identification by air traffic control and during inspections, ensuring that the aircraft can be easily registered and monitored throughout its operational life. It's critical for both safety and regulatory compliance, making this location particularly effective.

The other suggested locations, such as the wings, cockpit, or under the tail section, do not typically comply with FAA requirements for the registration number’s visibility and accessibility, which is why they are not correct options.
