Action
Notice of proposed rulemaking (NPRM).
Summary
This action would amend the regulations applicable to operators of certain airplanes used in Title 14 Code of Federal Regulations part 121 operations and certificated for flight in icing conditions. The proposed standards would require either the installation of ice detection equipment or changes to the Airplane Flight Manual to ensure timely activation of the airframe ice protection system. This proposed regulation is the result of information gathered from a review of icing accidents and incidents, and it is intended to improve the level of safety when airplanes are operated in icing conditions.
