## Abstract

The FAA amends the airworthiness standards for issuance of original and amended type certificates for airplane propellers. The previous propeller requirements did not adequately address the technological advances of the past twenty years. The new standards address these advances in technology and harmonize FAA and European Aviation Safety Agency propeller certification requirements, thereby simplifying airworthiness approvals for imports and exports.
