The FAA has issued Special Airworthiness Information Bulletin AIR-21-17R1 to advise owners, operators, crew, and passengers of techniques and equipment to avoid rotorcraft bird strikes as part of its new Rotorcraft Safety Promotion Concept (RSPC). According to the FAA, 90 percent of all bird strikes occur at altitudes of 3,500 feet agl and below.

Thus, the agency suggests several voluntary mitigation strategies for helicopter operators. They include installing equipment safety enhancements and flying helicopters with bird-resistant designs. Aircraft that fall into the latter category, according to the RSPC, include the Airbus H225 and BK 117 series; Leonardo AW139, AW169, and AW189; and the Sikorsky S-92A. Additionally, crews should wear helmets and visors when practical.
