On July 28, 2006, about 06:00 MST (Mountain Standard Time), a Robinson R44, N74780, collided with trees during an emergency landing near Flagstaff, Arizona. The pilot/operator was operating the helicopter under the provisions of 14 CFR Part 91. The private pilot sustained minor injuries; the helicopter sustained substantial damage. The cross-country personal flight departed Flagstaff Pulliam Airport, Flagstaff, Arizona, about 05:55 MST, with a planned destination of Phoenix Deer Valley Airport, Phoenix, Arizona. Instrument meteorological conditions prevailed, and no flight plan had been filed.
The pilot submitted a written report. He departed Flagstaff Pulliam Airport on the 185-degree radial of the Flagstaff very high frequency omni-directional radio range (VOR). About 9 nautical miles south of the airport, he encountered a lowering cloud layer, and could not maintain level flight. He decided to perform an autorotation into a clearing from about 100 feet above ground level. The helicopter touched down on its skids, but the landing area was slightly inclined. The tips of the rotor blades struck the ground and then hit a tree, causing the helicopter to roll over onto its right side.
The Flagstaff Pulliam Airport Automated Surface Observing System reported that the sky condition at 05:56 MST was 800 feet overcast.
The National Transportation Safety Board determines the probable cause(s) of this accident to be: the pilot's inadequate preflight planning decision to take off under a low ceiling into an area of mountainous terrain that resulted in an encounter with lowering clouds and forced the pilot to land in unfavorable terrain.
Robinson R44 N74780 was presumably repaired and returned to service, as it was sold on July 7,2007 to Charles V. Macadam of Portsmouth, New Hampshire. The registration N74780 was finally cancelled by the FAA on September 3, 2011 as "Sold to Mexico"
