  1. US Airways Flight 1549 Ditching on the Hudson River January 15, 2009Mark George Wildlife Factors

  2. Identification of Biological Remains • Smithsonian Institute Feather Lab • DNA and feather analysis: migratory Canada geese

  3. Improbable Bird Strike • Higher and farther from airport • 94% at or below 150 ft • Season with fewest strikes • January is second lowest month for strikes • Two engines damaged • One engine damaged - 30 times more likely • Migratory birds • Resident birds more numerous

  4. Airport Responsibility • Part 139.337 – wildlife hazard assessment (WHA), required if: • Multiple strikes have occurred • Damaging strike occurs • Engine ingestion • Hazardous wildlife is observed on or near the airport • LGA had a WHA and Wildlife Hazard Management Plan (WHMP)

  5. Airport Responsibility • Inside the perimeter fence • Hazardous species are: • Physically removed • Harassed from the area • Limited off-airport mitigation • US Airways 1549 strike occurred beyond LGA’s area of responsibility

  6. Airport Responsibility • 94% of wildlife strikes occur below 150 feet above ground level • On-airport mitigation has best chance of reducing strikes • Currently, about half of Part 139 airports • Have not had a WHA • Do not have a WHMP

  7. Research Activities • Birds not suicidal (Dolbeer) • Airplane-based systems • Aircraft lighting • Pulse lights • Lasers • Weather radar • USDA and FAA collaboration
