The investigation found that neither pilot adequately detected the other aircraft in time to prevent the collision, indicating a breakdown in visual scanning and situational awareness.

Another significant finding was the high volume of air traffic in the vicinity of the accident site. Ketchikan is a popular destination for sightseeing flights, particularly during the tourist season, which leads to congested airspace. The investigation noted that the high density of air traffic increased the complexity of the operational environment and placed additional demands on pilots to maintain vigilance and avoid conflicts. Furthermore, the investigation examined the role of communication procedures between the aircraft and air traffic control (ATC). While the area was not under active ATC control, the investigation considered whether improved communication protocols or air traffic management strategies could have enhanced safety in the area. The NTSB also assessed the weather conditions at the time of the accident, noting that while the weather was generally good, certain atmospheric conditions might have affected visibility or contributed to visual illusions that made it more difficult for the pilots to detect each other's aircraft.

Moreover, the NTSB's investigation delved into the operational practices of the air tour operators involved. This included a review of their training programs, safety management systems, and adherence to regulatory requirements. The investigation sought to identify any deficiencies in these areas that might have contributed to the accident. The NTSB also evaluated the regulatory oversight provided by the Federal Aviation Administration (FAA) to determine whether there were any gaps in the surveillance or enforcement of safety regulations. By examining these broader systemic factors, the NTSB aimed to develop comprehensive safety recommendations that address not only the immediate causes of the accident but also the underlying conditions that contributed to it. The ultimate goal of the investigation was to prevent similar accidents from occurring in the future by improving aviation safety practices and regulations.
