        <RULE_TITLE>Part 121--Activation of Ice Protection</RULE_TITLE>
        <ABSTRACT><![CDATA[This rulemaking would amend the regulations applicable to operators of certain airplanes used in air carrier service and certificated for flight in icing conditions.  The 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 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.]]></ABSTRACT>
