        <RULE_TITLE>Medium Flocking Bird Test at Climb Condition</RULE_TITLE>
        <ABSTRACT><![CDATA[The FAA is amending certain airworthiness regulations to add a new test requirement addressing engine bird ingestion.  This rule would ensure that turbofan engines can ingest the largest medium flocking bird into the engine core at climb conditions.  This final rule requires that, to obtain certification of a turbofan engine, a manufacturer must show the engine core can continue to operate after ingesting such a bird while operating at a lower fan speed associated with climb or approach.]]></ABSTRACT>
