NTSB Narrative Summary Released at Completion of Accident

On October 20, 2014, about 1045 Pacific daylight time, an experimental amateur-built Sonex Tri-gear, N91922, collided with terrain near Fawnskin, California. The pilot/owner was operating the airplane under the provisions of 14 Code of Federal Regulations (CFR) Part 91. The private pilot sustained fatal injuries. The airplane sustained substantial damage during the accident sequence. The cross-country personal flight departed Big Bear, about 1035, with a planned destination of Mesa, Arizona. Visual meteorological conditions (VMC) prevailed, and no flight plan had been filed. Witnesses observed the airplane about 200 above ground level over Big Bear Lake, but noted that this was below the level of surrounding terrain. As the airplane approached a cove, it banked left to almost 90 degrees. The nose dropped to a nearly vertical attitude until ground impact. The National Transportation Safety Board investigator-in-charge (IIC) and inspectors from the Federal Aviation Administration (FAA) examined the wreckage on site. The nose of the airplane and the wing's leading edges exhibited up and aft crush damage. The engine partially separated, but maintained its position on the airframe. One of the wooden propeller's blades splintered near the hub, and the pieces were buried in the ground; the other blade splintered about halfway to the tip. All flight control remained in place. The wreckage was recovered to a secure location for further examination.
