Airworthiness Standards; Continued Rotation and Rotor Locking Tests, and Vibration and Vibration Tests

This amendment revises the Federal Aviation Administration's (FAA's) continued rotation and vibration certification standards for the issuance of original and amended type certificates for aircraft engines. This amendment is the result of an effort to harmonize the Federal Aviation Regulations (FAR's) with European requirements being drafted by the Joint Aviation Authorities (JAA). This amendment will provide nearly uniform requirements that will simplify international airworthiness approval, while maintaining a level of safety equivalent to that established by the current standards.
