What must an aircraft owner do if the aircraft was not approved for return to service after an annual inspection?

When an aircraft is not approved for return to service after an annual inspection, the owner must obtain a special flight permit. This permit is necessary because it allows the aircraft to be operated under specific conditions despite not meeting the normal airworthiness standards. It is typically issued for the purpose of ferrying the aircraft to a location where necessary repairs can be made or for conducting test flights after work has been performed.

The special flight permit ensures that the flight can be conducted safely, while also adhering to regulatory requirements. It is crucial for operating an aircraft that has not received a standard return to service approval to ensure compliance with safety regulations and maintain the integrity of the aviation system.

In contrast, flying without approval, performing repairs on-site without addressing the underlying issues found during the inspection, or simply waiting for the next inspection are neither legally nor safely advisable options. Therefore, securing a special flight permit is the correct and responsible action to take in this situation.
