REPUBLIKA.CO.ID, JAKARTA -- Indonesia's National Transportation Safety Committee (KNKT) has worked on coordination with the US National Transportation Safety Board (NTSB) to investigate the causes of the Lion Air flight JT 610 plane crash on Monday. KNKT Chief Soerjanto stated that 16 personnel of the NTSB had arrived in the capital city to help in the investigation, as the ill-fated aircraft was manufactured by Boeing, a US multinational company.

"The aircraft manufacturer and the transportation safety board in the respective country must assist in the investigation process when its aircraft are involved in an accident," Soerjanto said at the Jakarta International Container Terminal 2 (JICT2) in Tanjung Priok Port here on Thursday.

He noted that the KNKT can access any aircraft-related data. "Boeing will help NTSB, and the NTSB will help us. That is the flow," he revealed.

Currently, three NTSB personnel have monitored the evacuation process at the JICT2 and the investigation conducted by the Indonesian authority so far. "We have shared data," Soerjanto noted.

The Lion Air flight JT 610 aircraft crashed some 13 minutes after taking off from Jakarta and en route to Pangkalpinang, Bangka Belitung Province, on Monday morning. The aircraft departed from Jakarta at 6:20 a.m. local time and was scheduled to arrive in Pangkalpinang at 7:05 a.m. local time, according to the Depati Amir airport authority in Pangkalpinang.

Before it lost contact, the aircraft had sought permission to return to Jakarta due to a problem. The aircraft carried 178 adult passengers, three infants, and six crew members as well as a pilot of Indian nationality and a co-pilot.

Meanwhile, a black box of JT 610 was found and retrieved from the waters of North Karawang, West Java, on Thursday morning. The black box was found at a depth of 25-35 meters under the sea and had drifted for some 100 meters from the initial estimated location.

The black box was sent to the Tanjung Priok seaport and then handed over to officials of the National Committee for Transportation Safety.
