What action is required when an aircraft is not in a condition for return to service?

When an aircraft is not in a condition for return to service, obtaining a special flight permit is required. This permit allows an aircraft that is not airworthy to be flown under specific conditions to a location where necessary repairs or inspections can be made. The special flight permit ensures that the aircraft can be operated safely and legally, taking into account potential limitations and safety measures that must be followed during the flight.

This requirement is critical because operating an aircraft that is not in a condition for return to service without proper authorization could pose serious safety risks to the pilot, passengers, and others on the ground. The special flight permit serves as a legal framework that acknowledges the aircraft's condition while providing a route to rectify the situation. The scope of the permit typically specifies the permissible flight conditions, which may include limitations on flight routes, altitude, or the presence of certain equipment necessary for safe operation.

Other options do not meet the regulatory requirements or safety standards necessary for operating an aircraft that is not airworthy.
