NTSB investigators may not have traveled in support of this investigation and used data provided by various sources to prepare this aircraft accident report.

The airplane's wreckage was found in mountainous terrain. Investigators found no anomalies to preclude normal operation of the airframe or engine. The owner had recently received a check out in the airplane. However, he was told not to take passengers or fly around in the mountains until receiving training in mountain flying techniques. The toxicology report for the pilot notes the finding of tetrahydrocannabinol (THC - the primary active substance in marijuana) and tetrahydrocannabinol carboxylic acid (THC-COOH - an inactive metabolite of THC) at levels suggesting very recent use, certainly within 3 hours prior to the crash, and possibly much more recently. The pilot's judgment and/or abilities were likely impaired.

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

The pilot failed to maintain clearance from mountainous terrain. A contributing factor was the pilot's impairment from ingestion of marijuana.
