## Factual narrative

On May 9, 2012, at 1450 local time, a Sukhoi SJ100-95, Russian registration RP97004, collided with terrain about 35 miles south of Jakarta, Indonesia. The airplane was on a demonstration flight. The 40 passengers and 4 crew were fatally injured, and the airplane was destroyed. This investigation is being conducted by the National Transportation Safety Committee of Indonesia (NTSC/KNKT). As the state of design and manufacture of the the ACSS/L3 Terrain Warning and Traffic Collision Avoidance System (T2CAS), the NTSB appointed a U.S. accredited representative upon being invited to do so by the NTSC. All inquiries should be directed to the NTSC at: National Transportation Safety Committee Ministry of Transportation Building 3rd Floor Jl. Medan Merdeka Timur No. 5 Jakarta 10110 Indonesia www.knkt.go.id
