JAKARTA - The black box Flight Data Recorder (FDR) of the Sriwijaya Air SJ-182 plane that crashed in the Thousand Islands was found. Now it is the turn of the National Transportation Safety Committee (KNKT) to analyze the FDR black box data.
"Today we can find a flight data recorder and two pinger. But indeed the pinger is separated from the black box, but thank God we can find FDR. Please pray for the public so that the reading of the FDR data which we estimate will take two to five days will run smoothly and can immediately unravel the mystery that caused this accident, "said KNKT Chairman Soerjanto Tjahjono during a press conference at the main search post for Sriwijaya Air SJ-182 aircraft at JICT2. , Tanjung Priok, North Jakarta, Tuesday, January 12.
TNI Commander Marshal Hadi Tjahjanto said the discovery of part of the FDR was reported by the KSAL at around 16:40 WIB, Tuesday, January 12. At 14.00 WIB, according to the TNI Commander, the KSAL reported a fraction of the FDR black box Sriwijaya Air SJ-182.
"16.40 KSAL reports again that FDR has been found and it is also reported that two underwater beacons were found. This means that CVR still needs to be searched without the help of these beacons. However, we believe that all the beacons in the cockpit voice are found in the vicinity with high confidence so the cockpit voice will be found, "said Marshal Hadi Tjahjanto at the main post for the search for Sriwijaya Air SJ-182 aircraft at JICT2, Tanjung Priok, Tanjung Priok.
The black box was put into a box filled with brownish water, then taken by Sea Rider by several divers, including Kopaska and Dislambair.
Temporary Analysis of the NTSCPreviously, the Chairman of the National Transportation Safety Committee (KNKT), Soerjanto Tjahjono, said that his party had conducted a temporary analysis regarding the downing of the Sriwijaya Air SJ-182 aircraft.
The KNKT collects radar data (ADS-B) from Perum LPPNPI (Airnav Indonesia). From this data, it was recorded that the plane was airborne at 14:36 WIB, flew towards the northwest and at 14:40 WIB the plane reached an altitude of 10,900 feet.
When it experienced a flight stall or malfunction, the Sriwijaya Air SJ-182 aircraft began to descend. The latest data on the aircraft that can be recorded stopped at an altitude of 250 feet or about 76 meters.
"Data recorded up to 250 feet indicates that the aircraft system is still functioning and capable of transmitting data. From this data we suspect that the engine was on before the plane hit the water," Soerjanto said in his statement, Tuesday, January 12.
Then, based on other field data obtained by the NTSC and KRI Rigel, the wreckage distribution is 100 meters wide and 300 - 400 meters long.
"This wide distribution is consistent with the assumption that the aircraft did not experience an explosion before hitting the water," said Soerjanto.
The findings of aircraft parts that have been collected by Basarnas, one of which is the engine part, namely a turbine disc with a damaged fan blade.
"The damage to the fan blade indicates that the engine was still working during the collision. This is in line with the suspicion that the aircraft system is still functioning up to the aircraft at an altitude of 250 feet," he said.
