What happened
On September 4, 20 5, at approximately 11:05 CDT, a Beech K35, registration N6021E, was involved in an accident near Cambridge, Minnesota. The aircraft was being operated under 14 CFR Part 91 for personal use.
According to ADS-B data, the pilot departed from Anoka County/Blaine Airport (ANE) at 10:52. The flight was intended for Cambridge Municipal Airport (CBG), a non-towered facility. The aircraft was traveling north toward the approach end of runway 34 when the ADS-B signal terminated approximately 2.38 miles south of that runway. The aircraft eventually came to rest upright in a grass field located about 0.37 miles from the approach end of runway 16. The impact resulted in 1 fatal injury to the pilot.
The investigation
The aircraft sustained substantial damage to the fuselage and both wings. An onsite examination of the airframe confirmed that flight control cables were continuous. The flaps and main landing gear were found in the retracted position, and the pitch trim was set at 10 degrees with the trim tab down.
The fuel selector valve was positioned to the auxiliary fuel tank. Investigators recovered approximately 18 gallons of fuel from the right wing main tank and about one gallon from the right wing auxiliary tank. No fuel could be recovered from the left wing tanks due to impact damage. The fuel strainer contained no debris or water contamination.
An examination of the Continental Motors IO-470-C engine revealed that the fuel hose supplying fuel from the firewall to the fuel pump was fractured at the fitting. However, the pump drive coupling was intact, and the fuel metering valve and finger screen showed no signs of contamination. No fuel leaks or loose b-nuts were observed on the engine, and the fuel manifold was found to be free of debris.
