Incident Overview
A pilot reported that while following a company airplane approximately 3-5 miles ahead through a mountain pass, he lost sight of the lead aircraft. He subsequently flew through an incorrect pass and entered clouds. In response, the pilot initiated a 180-degree turn, reduced speed, and began a descent. Upon noticing a snow-covered glacier, he executed a landing on the surface.
The pilot stated that the intended pass was to his right, but he did not execute the turn and instead flew straight ahead into a canyon.
Company Training and Procedures
The chief pilot had conducted a training flight with the pilot, during which the correct pass and associated procedures were demonstrated. The company requires pilots to view a video that outlines policies and procedures for mountain flying and pass penetration. However, the company's training manual contains no references to training in mountainous terrain or mountain pass operations, nor does it reference the video.
Further, the company operations manual does not address minimum weather operations, mountain operations, or mountain pass operations.
Investigation Findings
No additional details regarding the aircraft, location, date, or occupants were provided in the source material. The circumstances of the event highlight a discrepancy between required training materials and documentation.
