NTSB narrative
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.
Probable cause
The inadvertent in-flight collision with several Mallard ducks.

- Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
- Filled from the NTSB case API where the bulk record had no value: local date, investigation status. Values present in the bulk record are kept.
- The date is the local date; the NTSB stores the UTC date 2010-04-07.
