When ferrying an airplane for engine repair, what is the requirement regarding onboard personnel?

The requirement that only required flight crewmembers may be onboard during a ferry flight for engine repair is established to ensure safety and compliance with regulatory standards. In this scenario, the primary concern is to minimize the number of people on board to reduce risk and potential complications during the flight.

In ferry flights, the primary purpose is the safe transportation of the aircraft to a maintenance facility for necessary repairs. Therefore, it is deemed essential that only those individuals who are part of the flight crew, who are necessary for the operation and safety of the flight, are present. This typically includes the pilot(s) and any other crew required for the safe operation of the aircraft.

Onboard personnel limits are in place to ensure that the flight can be conducted with optimal safety and efficiency, as well as to comply with federal regulations that govern the operation of aircraft. Including family members, additional maintenance staff, or passengers not directly involved in the functioning of the flight could increase liability and complicate the situation unnecessarily.
