From the Wikipedia article
On 11 March 2018, a Bombardier Challenger 604 private jet, owned by Turkish group Başaran Holding, crashed in the Zagros Mountains near Shahr-e Kord, Iran, while returning to Istanbul from Sharjah. All three crew members and eight passengers on board were killed.
Investigation and cause
Investigation
The aircraft's two flight recorders (the flight data recorder and the cockpit voice recorder) were recovered for analysis.
In September 2018, the Aircraft Accident Investigation Board of the Iranian civil aviation authority published a preliminary report indicating that, shortly before reaching cruise altitude, a discrepancy between the airspeed indications shown to the two pilots became apparent, with one indicating an overspeed condition. Engine power was reduced, and shortly after the stick-shaker activated. The aircraft subsequently stalled and entered a steep descent during which both engines flamed out. Control was not regained and the aircraft eventually struck a mountainside. In March 2020, the AAIB issued its final report, concluding that the accident was caused by insufficient training for airspeed indication failure and poor crew resource management.
