On May 13, 2019, a de Havilland Canada DHC-2 Beaver floatplane operated by Mountain Air Service collided with a Taquan Air de Havilland Canada DHC-3 Turbine Otter floatplane over George Inlet, Alaska, United States. The DHC-2 broke up in mid-air with the loss of all four passengers and the pilot. The DHC-3 pilot was able to maintain partial control – enough to perform a forced landing on George Inlet – but the aircraft sustained substantial damage in the collision and the landing; the pilot suffered minor injuries, nine passengers suffered serious injuries, and one passenger was killed. Both aircraft were conducting sightseeing flights under visual flight rules, which state that the pilot of each aircraft is responsible for visually ensuring adequate separation from other air traffic, commonly known as "see and avoid". In April 2021, the National Transportation Safety Board (NTSB) attributed the accident to "'the inherent limitations of the see-and-avoid concept, along with the absence of alerts from both airplanes' traffic display systems." Due to the angle of approach, the DHC-2 pilot's view was obscured by the aircraft structure and the passenger sitting in the right-hand seat, while the DHC-2 was blocked from the DHC-3 pilot's view by the left front window post. Both aircraft were equipped with Automatic Dependent Surveillance–Broadcast (ADS–B) traffic alert systems, but the DHC-3 automatic alert feature had been disabled by an equipment change, while the alert features of the DHC-2 system did not trigger because avionics in the DHC-3 were not broadcasting the aircraft's altitude. The NTSB also identified Taquan's inadequate preflight checklist and the Federal Aviation Administration's failure to require Taquan to implement a safety management system as contributing factors.
