What happened
A commercial pilot departed Skagway, Alaska, as part of a two-airplane air tour flight over a national park. The intended route involved flying southbound, climbing over steep mountains, and descending into Glacier Bay. During the flight, the pilot of the second aircraft observed that low clouds, rain, and fog within the mountain pass would prevent passage through the standard route.
The two pilots discussed alternative flight paths. The accident pilot decided to fly on a heading of 240 degrees to reach the other side of the terrain. The pilot of the second airplane expressed disagreement with this decision, stating he believed it was a bad idea and would not follow. The final radio transmission from the accident aircraft included the pilot stating, "...I'm sure that it's clear on the other side. I'll see you on the other side." No further communications were received.
Following an emergency locator transmitter (ELT) signal, a search began around 1600. Due to poor weather, rescue crews faced difficulties reaching the site. The wreckage was located at approximately 1859 on steep, snow-covered mountainous terrain. There were 6 fatalities resulting from the crash.
Findings
A toxicology examination of the pilot identified the presence of codeine and prescription antidepressant drugs. Use of these substances is prohibited by the FAA for pilots.
