Revised performance and handling requirements for normal- (Part 27) and transport-category (Part 29) rotorcraft have been proposed. The FAA said the proposals are prompted by “advances in design and operational trends.” Some current Part 27 and 29 regulations do not reflect “safety levels attainable by modern rotorcraft.” Areas targeted for revision are weight limits; minimum operating speeds; high-speed envelope; controllability and maneuverability; and stability. Comments are due October 23. Contact the FAA at (817) 222-5135.
