Accident investigation
Swiss Transportation Safety Investigation Board (STSB) investigators recently released a report on the crash of a vintage Junkers Ju 52 aircraft, operated by Ju-Air.(1)
On 4 August 2018 the aircraft took off from Locarno Airport for a commercial sightseeing flight across the Swiss Alps. After 40 minutes, the aircraft dived nearly vertically into the ground near Piz Segnas in the mountains of eastern Switzerland. None of the 20 passengers or crew survived.
The report found that the aircraft had stalled after the pilots navigated it in a high-risk manner into a narrow valley at a low altitude and a dangerously low airspeed with its centre of gravity out of limits.
