Definition
A written permission issued by the FAA allowing the operation of an aircraft that does not meet current airworthiness requirements, or that is being flown for a purpose outside the limits of its standard airworthiness certificate. It specifies the conditions, route, altitudes, and limitations under which the flight may be conducted.
Plain English
An official FAA approval that lets a pilot fly an aircraft in a situation where it would normally not be allowed, with specific rules attached to that flight.
Context Anchor
Seen in aircraft paperwork, FAA compliance, and non-routine flight planning, especially when a foreign-registered aircraft needs to operate in U.S. airspace.
Derivation
“Special” means outside the normal case, and “authorization” means official permission. In this term, the words point to a limited FAA permission for a particular situation, not a general right to fly the aircraft anytime.
Why Pilots Care
It enables legal movement of aircraft that would otherwise be grounded due to certification issues.
Intuition Check
Do not read “special” as meaning VIP, unusual, or simply important. Here it means the flight needs a specific FAA approval because it does not fit the normal paperwork requirements.
Example Sentence 1
Because the aircraft was overdue for its annual inspection, the owner obtained a Special Flight Authorization to ferry it to the maintenance shop.
Example Sentence 2
Without a Special Flight Authorization, the experimental aircraft could not legally depart for the airshow.
