Key Takeaways:

A routine flight tragically crashed due to a catastrophic bird strike (Canada goose) at 4,500 feet, highlighting that wildlife strikes are a common, costly, and potentially fatal hazard for aviation, often going unreported.
Wildlife collisions are frequent, with an estimated 25 strikes daily in the U.S., causing significant aircraft damage, downtime, injuries, and fatalities annually.
Pilots can mitigate risks by using online tools like the Bird Avoidance Model (BAM) and Avian Hazard Advisory System (AHAS) to assess strike probabilities and adjust flight plans, times, or altitudes; reporting all strikes is crucial for data collection and safety improvements.

It was a routine flight in every way. A University of North Dakota flight instructor took off from Grand Forks, North Dakota, at 5:45 p.m. with a private pilot who was in the university’s commercial/instrument flight program, for a three-leg, cross-country night flight in a twin-engine Piper PA-44-180 Seminole. It was a clear night with winds out of the northwest at 10 to 15 knots, plus an airmet for possible moderate turbulence below 8,000 feet. The pilot had carefully planned the flight, utilizing DUAT to assess the weather and filing two VFR flight plans with flight service.

After an intermediate stop at Hutson Field Airport in Grafton, North Dakota, they arrived at St. Paul Downtown Airport in St. Paul, Minnesota, at 8 p.m. and used a crew car to go for dinner. Before their departure the pilots had the airplane fuel tanks filled with 42 gallons of 100LL aviation fuel, which was more than enough to get them back to Grand Forks with adequate reserves.
