Abstract : A recent Canadian study involving the years 1977-1982 inclusive relates engine bird strike rates to different aircraft types and to different engine locations on similar-sized aircraft. Incidents of engine damage, including simultaneous multi-engine strikes are related to aircraft types and engine locations. The data presented suggest high vulnerability to bird strikes, bird ingestion and related damage in the case of large, quiet, underwing-mounted engines. They also suggest much lower strike, ingestion and damage rates for small, noisy, rear-mounted engines. Where the same engines are used in both locations the strike rates are more than four times greater in the underwing location. The implications for modern aircraft using 2 large, quiet, underwing-mounted engines (B767,B757 and A300) are considered.
