Certification of Part 23 Turbofan- and Turbojet-Powered Airplanes and Miscellaneous Amendments

摘要

This action enhances safety by amending the applicable standards for part 23 turbofan- and turbojet-powered airplanes--which are commonly referred to as ``part 23 jets,'' or ``jets''--as well as turbopropeller-driven and reciprocating-engine airplanes, to reflect the current needs of industry, accommodate future trends, address emerging technologies, and provide for future airplane operations. This action is necessary to eliminate the current workload of processing exemptions, special conditions, and equivalent level of safety findings necessary to certificate jets. The effect of the changes will: Enhance safety by requiring additional battery endurance requirements; increase the climb gradient performance for certain part 23 airplanes; standardize and simplify the certification of jets; clarify areas of frequent non-standardization and misinterpretation, particularly for electronic equipment and system certification; and codify existing certification requirements in special conditions for jets that incorporate new technologies.
