National Committee on Transportation Safety (KNKT) published the final investigation report on the Sukhoi plane crash, Thursday (18/12), which occurred during a test flight on 9 May 2012 at Mount Salak, Bogor, Jawa Barat.

Tatang Kurniadi, Chief of KNKT, concluded that there was no system error during the flight. This information derived from the plane Cockpit Voice Recorder (CVR) and Flight Data Recorder (FDR).

Tatang further explained that Terrain Awareness Warning System (TAWS) was operating well. TAWS warned the pilot once on the “terrain ahead” and six times to “avoid terrain”.

“Plane crash might have been avoided if the pilot reacted within 24 seconds after the first TAWS warning,” said Tatang via the KNKT website.

Investigation, which was led by Professor Mardjono, concluded that the following are some of the factors that contributed to the crash: 1. Pilot was not aware of the mountainous area and ignored the warning from TAWS; 2. Jakarta Radar was not provided with the Minimum Safe Altitude Warning (MSAW) information on Mount Salak route; and 3. Pilot was engaged in a long conversation with a prospective buyer.

Russia and Indonesia cooperated with various experts during the investigation, including, among others, Inter-Country Aviation Committee from JSC firm, Russian Trade Ministry, and KNKT.

“The cooperation was effective and constructive and was carried out in mutual support,” said Mikhail Yurievich Galuzin, Russian Ambassador in Indonesia.

Mikhail confirmed that the investigation report is objective and balanced. “It was conducted in accordance with the International Civil Aviation Organization (ICAO) standard,” noted Mikhail.

The investigation report has been received by all parties involved and Mikhail stated that he hopes that it will be used to improve aviation safety systems.

“We send our deepest condolences to the victims of the Sukhoi Superjet 100 plane crash,” expressed the Russian Ambassador.

For background information, the incident resulted in 45 deaths, including two pilots, one navigator, one flight test engineer, and 41 passengers. Among the passengers, there were 4 employees of Sukhoi Civil Aircraft Company (SCAC), one employee of plane engine company (SNECMA), 34 Indonesian citizens, one American citizen, and one French citizen.

Mikhail concluded that he hopes that the cooperation on the investigation between Russia and Indonesia will promote and develop good bilateral relations between the two countries, especially in transportation sector, such as the civil aircraft trade.
