Narrative:The pilot was performing a personal flight with one passenger to hunt sheep in remote mountainous terrain. After the pilot failed to report to his place of employment 4 days after their departure, an extensive SAR operation was launched the following day. The wreckage was located 2 days after the SAR operation began in a remote snow-covered mountainous valley. The airplane came to rest upright, with the fuselage banking to the right, both wings indicating forward/aft crushing, and the tail slightly elevated with little impact damage. The date and time of the accident could not be determined. Thus, the meteorological conditions before and at the time of the accident could not be determined.
A postaccident examination of the airframe and engine revealed no pre-impact mechanical malfunctions or failures that would have precluded normal operation. The aft right wing spar exhibited signs of compression bending, with the right forward spar exhibiting aft bending. The aft left wing spar bolt indicated a failure in tension, and the left forward spar indicated forward bending. A postcrash fire incinerated a large portion of the wreckage.
The pilot did not file a flight plan. If the pilot had filed a flight plan, SAR assets would have focused on a specific search area which would likely have reduced the time to find the airplane. Although the accident was likely not survivable due to the impact forces, a filed flight plan would have reduced the risk to aerial SAR assets operating in remote mountainous terrain.
The National Transportation Safety Board determines the probable cause(s) of this accident as follows:
An impact with terrain for reasons that could not be determined based on the available information.
