Cessna P337G N4CU accident near Santa Paula, California

Probable cause

The noninstrument-rated pilot's decision to conduct a visual flight in instrument meteorological conditions, which resulted in controlled flight into mountainous terrain.

NTSB analysis

The noninstrument-rated commercial pilot departed for the cross-country flight over mountainous terrain in instrument meteorological conditions. A witness observed the airplane take off from runway 22, disappear into an overcast layer at 300 ft above ground level (about 550 ft mean sea level [msl]), and then reappear heading in the opposite direction. The witness reported that the airplane departed the traffic pattern heading northeast. The wreckage was located in mountainous terrain at an elevation of 1,223 ft msl, 2.8 mi east of the departure airport. Meteorological data indicated that, at the time of the accident, a cloud layer extended over the accident site from about 550 ft msl to about 2,100 ft msl, and, at the elevation of the accident site, the terrain would have been obscured by clouds. Examination of the wreckage did not reveal evidence of any preimpact mechanical malfunctions or anomalies that would have precluded normal operation of the airframe or engine. The orientation of the wreckage indicated that, at impact, the airplane was heading south and traveling at a ground speed consistent with normal traffic pattern speeds. The damage to the airplane was consistent with controlled flight into the terrain, and the airplane's impact heading was consistent with the pilot attempting to return to the airport when the airplane collided with the rising terrain.
