Sukhoi Superjet 100 Demonstration Flight

Flight Number


Date of Crash


Location of Crash

Jakarta, Indonesia

A demonstration flight departing from and returning to Halim Perdanakusuma Airport in Jakarta, Indonesia violently crashed in Mount Salak in 2012. Though the crash was attributed to pilot error, further investigation provided insight as to how a mechanical malfunction had led to the disaster. The Terrain Avoidance Warning System alarms the pilots when the aircraft is in an area of dangerous terrain. However, that system was prone to give nuisance or false warnings. Shockingly, the system could be disabled so that nuisance warnings no longer sounded. As a result, the system did not provide adequate warnings and the aircraft crashed into a mountain and all aboard perished upon impact.
