On October 27, 2014, about 0740 mountain daylight time, a Mooney M20E airplane, N3539X, was substantially damaged when it impacted the ground just north of the Boulder Municipal Airport (KBDU), Boulder, Colorado. A postimpact fire ensued. The airline transport pilot was fatally injured. The airplane was registered to and operated by a private individual under the provisions of 14 Code of Federal Regulations Part 91 as a personal flight. Visual meteorological conditions prevailed for the flight, which operated without a flight plan. The flight was originating at the time of the accident and was en route to Rocky Mountain Metropolitan Airport (KBJC), Denver, Colorado. According to family and friends of the pilot, he was taking the airplane to KBJC to have routine maintenance performed on the airplane. Several witnesses reported seeing the airplane as it took off from runway 08. Shortly after liftoff, the airplane banked to the left and continued to the north in a steep bank and a nose low attitude. The airplane impacted the ground, nearly vertical, and came to rest on the north edge of Independence Road, just north of KBDU. The airplane was substantially damaged by the impact sequence and a postimpact fire. The main wreckage included the engine and propeller assembly, the fuselage, the empennage, and both wings.
