2016 East Java mid-air collision

* Garuda Indonesia Flight 471
* Lion Air Flight 710

## Garuda Indonesia Flight 471

**Garuda Indonesia Flight 471** and **Lion Air Flight 710** were passenger flights between Jakarta and Denpasar for Flight 471 and Denpasar to Palembang for Flight 710 when the Bombardier CRJ100 and Boeing 737-800 collided above Mount Argopuro, East Java, Indonesia, The upturned wingtip of the CRJ sliced off about half of the 737's Tail and right horizontal stabilizer. The 737 later crashed into an area of dense rainforest, killing all 170 passengers and crew on board. Despite sustaining serious damage to its left wing and left horizontal stabilizer, the CRJ jet safely landed at Surabaya with its 60 occupants uninjured.

## Investigation

The accident was investigated by the NTSC (or National Transportation Safety Committee) and the U.S. National Transportation Safety Board (NTSB), and a final report was issued in 2017. NTSC concluded that the accident was caused by air traffic control (ATC) errors, combined with mistakes made by the Maintenance team of Garuda Indonesia, including a failure to recognize that their traffic collision avoidance system (TCAS) was not activated, while the NTSB determined that both flight crews acted properly and were placed on a collision course by ATC, deeming the CRJ pilots' of a malfunction of their TCAS system to be only a contributing factor rather than a direct cause.

## CVR

the FDR wasn't released to the public but the CVR was, the CVR appears to have both Indonesian and English.
