This report discusses the May 13, 2019, accident involving a de Havilland DHC-2 (Beaver) airplane, N952DB, and a de Havilland DHC-3 (Otter) airplane, N959PA, which collided in midair about 8 miles northeast of Ketchikan, Alaska. The DHC-2 pilot and four passengers sustained fatal injuries. The DHC-3 pilot sustained minor injuries, nine passengers sustained serious injuries, and one passenger sustained fatal injuries. The DHC-2 was destroyed and the DHC-3 sustained substantial damage. The National Transportation Safety Board (NTSB) identified seven safety issue areas in this report: (1) the inherent limitations of the see-and-avoid collision avoidance concept, (2) the benefit of automatic dependent surveillance-broadcast (ADS-B) Out- and In-supported traffic advisory systems in high-traffic tour areas, (3) the lack of an ADS-B In requirement for Title 14 Code of Federal Regulations (CFR) Part 135 operations, (4) the lack of cockpit display of traffic information alerting on both aircraft, (5) the loss of alerting capabilities with ADS-B systems installed as part of the Federal Aviation Administration’s (FAA) post-Capstone upgrade program, (6) an inadequate checklist used in Taquan Air’s operation, and (7) the lack of a requirement for safety management systems in Part 135 operations. As a result of this investigation, the NTSB makes six new safety recommendations to the FAA and one recommendation each to ForeFlight, Taquan Air, aviation industry groups, and aviation educator groups. The NTSB also reiterates one safety recommendation to the FAA.
