The FAA proposes the addition of a new test requirement to the airworthiness regulation addressing engine bird ingestion. The current regulation ensures bird ingestion capability of the turbofan engine fan blades, but the existing test conditions do not adequately demonstrate bird ingestion capability of the engine core. This proposed rule would require that, to obtain certification of a turbofan engine, a manufacturer must show that the engine core can continue to operate after ingesting a medium sized bird while operating at a lower fan speed associated with climb or landing. This new requirement would ensure that engines can ingest the largest medium flocking bird required by the existing rule into the engine core at climb or descent conditions.
