NTSB Identification: WPR10FA305
14 CFR Part 91: General Aviation
Accident occurred Friday, June 18, 2010 in Seligman, AZ
Probable Cause Approval Date: 05/26/2011
Aircraft: Hawker Beechcraft Corporation A36, registration: N155FT
Injuries: 1 Fatal.

NTSB investigators either traveled in support of this investigation or conducted a significant amount of investigative work without any travel, and used data obtained from various sources to prepare this aircraft accident report.

The pilot departed on a visual flight rules flight on a dark night, and family members reported that he had been drinking alcohol and was under emotional distress. Toxicological testing gave no conclusive results as to the pilot's alcohol intoxication level, if any, at the time of the accident. Radar data identified as the airplane's flight track showed a progression from east to west, with the radar targets showing a gradual descent to the altitude of the mountainous terrain in the area, and then ending in the vicinity of the accident site. Very few ground reference lights existed in the area of the accident site and the moon was in its first quarter and would not have provided any significant illumination of the terrain. The radar data was consistent with the pilot's loss of situational awareness during the dark night and the airplane gradually descending into terrain. Examination of the recovered airframe and engine components revealed no evidence of preimpact mechanical malfunction.

The National Transportation Safety Board determines the probable cause(s) of this accident to be:

The pilot's failure to maintain clearance from mountainous terrain in the dark night.
