NTSB’s coded findings. Those marked are part of the probable cause; the rest are factors or other findings. Under each, the cases with the same finding.
Sequence of events
The events NTSB coded, in order, by phase of flight. The defining event is the one that best describes the accident. Under each, the cases with the same event anywhere in their sequence.
Analysis
The airplane collided with several Mallard ducks during an instructional flight in night visual meteorological conditions. The pilot-in-command reported that, as the airplane was descending through 4,200 feet, he heard a “loud pop” and felt a “violent rush of air.” The flight instructor, seated in the right seat, sustained serious injuries when one duck penetrated the right cockpit windshield and struck his face. The pilot-in-command seated in the left seat was not injured. The flight crew decided to return to the departure airport and made an uneventful landing. A postaccident inspection revealed that the airplane had received substantial structural damage to the right wing leading edge. All observed damage to the windshield and nose cone was consistent with the airplane colliding with several birds during flight.
Factual narrative
On April 6, 2010, at 2151 central daylight time, a Beech 95-B55, N70283, sustained substantial damage when it impacted several Mallard ducks during cruise flight at 4,200 feet over Center, North Dakota. Night visual meteorological conditions prevailed at the time of the accident. The flight instructor, seated in the right seat, sustained serious injuries when one duck penetrated the right cockpit windshield and struck his face. The pilot-in-command seated in the left seat was not injured. The flight was being operated by the State of North Dakota Attorney General’s Office as a public-use flight. The instructional flight departed Bismarck Municipal Airport (KBIS), Bismarck, North Dakota, at 2025, and was enroute to Mercer County Regional Airport (KHZE), Hazen, North Dakota. After the bird strike, the pilot-in-command diverted back to the departure airport and made an uneventful landing. At the time of the bird strike, the pilot-in-command was flying while using a view-limiting device to simulate instrument meteorological conditions. He reported that as the airplane was descending through 4,200 feet, he heard a “loud pop” and felt a “violent rush of air”. After the bird strike, there were several large portions of the right windshield missing and the flight instructor was bleeding from his face. The flight crew decided to return to KBIS instead of continuing to KHZE. The PIC declared an emergency with Bismarck approach control and requested that an ambulance meet the airplane after landing. A post-accident inspection revealed that the airplane had received substantial structural damage to the right cockpit windshield, right wing leading edge, and nose cone. All observed damage was consistent with the airplane colliding with several birds during flight.
