Full Narrative
On September 08, 2024, about 0650 Pacific daylight time, a Mooney M20F airplane, N9628M, was substantially damaged when it was involved in an accident near Cottonwood, Arizona. The pilot sustained serious injuries and later succumbed to his injuries. The airplane was operated as a Title 14 Code of Federal Regulations Part 91 personal flight.
The pilot departed from Deer Valley Airport, Phoenix, Arizona about 0625 with the intention of landing at Cottonwood Airport, Cottonwood, Arizona, and having breakfast with friends. A witness observed the airplane at a low altitude and then pitched up before colliding with a tree. The witness heard the engine operating as the airplane flew at a low altitude before it pitched up. He reported that the engine sound increased immediately before the airplane struck the tree.
Another witness, who lives about a block from the impact location, reported the airplane flew very low over his street and appeared to encounter a flock of about 20 birds that rose from a dead tree about 35 feet above the ground. He stated the birds were likely western bluebirds about 7 inches long and that large numbers had been roosting and feeding on berries across the street from his home. He observed the airplane turn left, appear sideways, and then pass out of view. He stated he heard the impact shortly thereafter but did not witness the collision.
The airplane came to rest inverted about 2,000 ft from the departure end of runway 32. The right fuel tank was breached and the fuel quantity before impact could not be ascertained. Three gallons of fuel were recovered from the fuel system as part of the retrieval efforts. There was evidence of fuel staining near the fuel caps on the upside-down wings, consistent with fluid in the wing tanks after impact. The landing gear had released from the uplocks but remained partially retracted within the wheel wells. The flaps were extended.
A piece of windscreen and numerous swabs of the airframe were sent to the Smithsonian Institution's Feather Identification Lab for examination. No bird DNA or feather fragments were detected in any of the samples.
The pilot succumbed to his injuries on October 15, 2024.
