FAR 21.213 — Provisional Airworthiness Eligibility
FAR 21.213 sets eligibility for Class I and Class II provisional airworthiness certificates, covering U.S. manufacturers, Part 121 carriers, and engine modifiers.
FAR 21.213 spells out who can apply for a provisional airworthiness certificate — a special certificate issued for aircraft that aren't yet fully type certificated but need to operate for testing or limited service. Three groups of U.S. citizens are eligible:
- U.S. manufacturers building aircraft inside the United States may apply for a Class I or Class II provisional airworthiness certificate for those aircraft.
- Part 121 air carriers (scheduled airlines) may apply for a Class II provisional airworthiness certificate for transport category aircraft, but only if the aircraft has either:
- A current Class II provisional type certificate (or amendment), or
- A current provisional amendment to a type certificate that was preceded by a Class II provisional type certificate.
- Aircraft engine manufacturers who install their own different type certificated engines on an existing type certificated aircraft may apply for a Class I provisional airworthiness certificate, provided the original aircraft was certificated in the normal, utility, acrobatic, commuter, or transport category.
This matters operationally because provisional certificates let manufacturers and airlines begin limited operations and crew training before final certification is complete.
