What is a special flight permit used for?

A special flight permit, also known as a ferry permit, is issued by aviation authorities to allow an aircraft that does not currently meet all the airworthiness requirements to fly under specific conditions. This permit is typically used for situations where an aircraft needs to be relocated for repairs, alterations, or to a maintenance facility after an issue has been identified.

For example, an aircraft may have incurred damage but is safe to operate for a short distance to a repair station. The special flight permit outlines the conditions under which the flight can be conducted, ensuring that any risks are mitigated while still enabling necessary operations. The permit does not provide indefinite authority for operation, as it is temporary and tied to the specific circumstances of the aircraft's airworthiness status.
