JAKARTA - Indonesia's air accident investigator will brief relatives of the 62 victims of last month's Sriwijaya Air crash in Jakarta on Wednesday morning (Feb 10) ahead of the release of a preliminary report in the afternoon, a family member told Reuters.

The briefing follows one held for families on Tuesday in Pontianak, the doomed flight's destination, and comes as divers search for the missing memory unit from the plane's cockpit voice recorder.

The 26-year-old Boeing Co 737-500 jet crashed into the Java Sea shortly after take-off from Jakarta, marking Indonesia's third major airline crash in just over six years and shining a spotlight on the country's poor air safety record.

Sriwijaya Air Flight 182

Sriwijaya Air Flight 182 was a scheduled domestic passenger flight from Jakarta to Pontianak, Indonesia. Five minutes after departing from Soekarno–Hatta International Airport on 9 January 2021, the Boeing 737-500 flying the route experienced an upset and crashed into the Java Sea off the Thousand Islands, killing all 62 people aboard. A search of the area recovered wreckage, human remains, and items of clothing, but no survivors. On 21 January, the search for survivors was halted and all are presumed dead. The flight data recorder was recovered on 12 January, whereas the data storage module of the cockpit voice recorder was recovered nearly three months after the crash.

During the search, the National Transportation Safety Committee used the engines and available data from Flightradar24, and hypothesised that the plane had been still responsive upon impact, where it had ruptured. Investigators announced a focus on the aircraft's autothrottle due to its previous malfunctions.


The aircraft involved was a Boeing 737-524, registered as PK-CLC . It was equipped with two CFMI CFM56-3B1 engines. At the time of the accident, the aircraft had accumulated 62,983 hours and 40,383 cycles.

The aircraft was manufactured in 1994, and had its maiden flight on 13 May 1994. It was first delivered to Continental Airlines on 31 May 1994 under the registration N27610. The aircraft was transferred to United Airlines in 2010 after Continental and United merged. On 15 May 2012, the aircraft was sold to Sriwijaya Air. It was the first of a total of fifteen 737-500s received by Sriwijaya Air in 2012 to replace their 737-200s. Sriwijaya Air named the aircraft Citra. Between 23 March and 23 October 2020, the aircraft was stored at Surabaya Juanda International Airport for repair. The Ministry of Transportation stated that it inspected the aircraft on 14 December 2020 and issued a new certificate of airworthiness on 17 December 2020. It resumed service on 19 December 2020

Passengers and crew

There were 62 people on board, of which 50 were revenue passengers . Of the remaining 12 crew members, six were operating crew on the flight, while the other six were deadheading as passengers. The majority of the passengers were residents from West Kalimantan. Among the passengers was Mulyadi Tamsir, a politician from the People's Conscience Party .

The active crew consisted of Captain Afwan, First Officer and four flight attendants. Afwan was a former pilot in the Indonesian Air Force.

The six deadheading crew and several revenue passengers had transferred to Flight 182 from an earlier NAM Air flight that did not operate.

The Associated Press, BBC News, HuffPost, The New York Times, The Wall Street Journal, and other media have reported that all people on board had been killed. At least 58 victims, including the captain, have been identified by the police.


The first report of the crash was made at 14:30 WIB , in which a fisherman said that an aircraft had crashed and exploded in the sea. The head of the Indonesian National Search and Rescue Agency , reported that the crash site was located 11 nmi from Soekarno-Hatta International Airport.

Personnel from a vessel provided by the Ministry of Transportation reported that body parts, fragments of clothing, electronics, personal belongings and wreckage had been recovered from the sea in waters near the Thousand Islands, with aviation fuel also reported around the location. The water near the crash site has a depth of around 15–16 m .

BASARNAS immediately deployed personnel to the crash site while the Indonesian National Police and the Ministry of Transportation set up crisis centres in Port of Tanjung Priok and Soekarno–Hatta International Airport. The Indonesian Navy deployed a number of vessels for the search and rescue operations, in addition to helicopters and KOPASKA personnel.

The Indonesian government requested assistance from the South Korean government with the search. Through the Korea - Indonesia Marine Technology Cooperation Research Center , the South Korean Ministry of Oceans and Fisheries deployed a research vessel equipped with a detector to Indonesia. At least 15 personnel from MTCRC were also sent. The Singaporean government also offered to provide assistance in the search which the Indonesian government later accepted.

On 10 January, the Indonesian Navy announced that the exact coordinates of the crash site had been pinpointed.


Rescuers managed to recover a life vest, pieces from the aircraft's fuselage, and a destroyed wheel rim of the Boeing 737. Most of the wreckage was found at a depth of 17–23 metres . On the night of 9 January, an emergency slide of the aircraft was recovered from the waters near Lancang Island, Thousand Islands. The scattered debris and the small pieces of the wreckage indicated a high-speed impact. Much more wreckage was found over the next few days.

On 10 January, the National Transportation Safety Committee reported that they had located the position of the cockpit voice recorder and the flight data recorder, but after the flight data recorder was retrieved at 16:00 WIB on 12 January, it was reported that beacons on both flight recorders were dislodged in the impact and the cockpit voice recorder would need to be found without the assistance from underwater guidance signals. The casing of the cockpit voice recorder was recovered on 15 January but the data storage module inside was missing. BPPT stated that the data storage module of the CVR was thought to be buried under the aircraft's wreckage. In the afternoon of 17 January, the CVR components and its casing, but without the data storage module, were handed over to the NTSC for further examination. The next day on 18 January, the search for the CVR, wreckage, and victims was extended for three more days.

On 21 January BASARNAS announced the search for victims and aircraft debris had been halted. A total of 122 pieces of debris had been recovered from the crash site, including one of the aircraft engines' turbines. As of 10 February, the search for the data storage module of the CVR was ongoing.

On 30 March, nearly 3 months after the crash, BASARNAS recovered the missing CVR component using a hopper dredger, at a depth of 14 meters, with coordinates of 5°57'51?S 106°34'31?E; the search operation was officially ended.
