## Abstract

This rule will amend the aircraft turbine engine rotor overspeed type certification standards. This action establishes uniform rotor overspeed design and test requirements for aircraft engines and turbochargers certificated by the FAA and the European Aviation Safety Agency (EASA). The rule also establishes uniform standards for the design and testing of engine rotor parts in the United States and in Europe, eliminating the need to comply with two differing sets of requirements.
