The larger air craft was operated by Taquan Air, a company whose history is coming to light for having a few serious crashes in recent years, but the history goes back further.
NTSB reports date back to 1992 when Taquan crashed in Metlakatla with no injuries.
In 1996, another crash just 18 miles SW of Ketchikan where the passengers survived, but the pilot was found dead still in the plane.
Again in 2007, a Taquan Air pilot and four passengers were killed after another otter aircraft encountered poor weather. Investigation ruled the accident caused by pilot misjudgment.
In 2012, another small accident in Ketchikan, not injuring any passengers but causing body damage to the plane.
Last summer, Taquan Air was involved in another collision on July 10, 2018. All 10 passengers and pilot survived, but six suffered serious injuries. Reports say the pilot was flying in low visibility conditions.
At this time, all scheduled Taquan Air flights are suspended. In terms of Mountain Air Service LLC, they are believed to have had a perfect safety record up to this point.
