Bird Ingestion Requirements

To obtain certification of a turbofan engine, the FAA is proposing that manufacturers must show that the engine core of newly designed engines can continue to operate after ingesting a medium-sized bird while operating at a lower fan speed associated with climb or landing. Current FAA regulations ensure bird ingestion capability of only the engine fan blades. The European Aviation Safety Agency (EASA) has notified the FAA that it intends to incorporate requirements similar to those proposed into its engine bird ingestion rule. Comments are due by September 4.
