An airworthiness certificate refers to a certificate issued by a representative of the Federal Aviation Administration which certifies that an aircraft is in a condition for safe operation.
The certificate must be displayed in the aircraft so that it is legible to passengers or crew. An airworthiness certificate is transferred with the aircraft.
The registered owner of an aircraft applies to the Federal Aviation Administration administrator for an airworthiness certificate for the aircraft. The administrator issues an airworthiness certificate when the administrator finds that the aircraft conforms to its type certificate and, after inspection, is in condition for safe operation. The administrator must register each airworthiness certificate and can include appropriate information in the certificate. The administrator can include in an airworthiness certificate terms required in the interest of safety. [49 USCS § 44704].
