The aircraft has so far not turned up anywhere else. A search is underway. Debris and body parts were located in waters of about 15 meters depth near Lancang Island. There are no signs of survivors.

Soekarno Airport confirmed radar and radio contact with the aircraft was lost. Data review is underway, further communication to be expected from the Ministry of Transport.

Indonesia's Ministry of Transport confirmed contact with the aircraft was lost. A search and rescue operation is in progress under the coordination of Basarnas. First units of Basarnas arriving at the crash site between Laki Island and Lancang Island have located debris. The Ministry subsequently confirmed the aircraft has crashed. The aircraft had departed Soekarno Airport at 14:36L, climbing through 1700 feet the aircraft was cleared to climb to FL290. Departure control subsequently noticed that the aircraft was not on its assigned heading of 075 degrees, but tracking northwesterly and queried the crew about the heading at 14:40L, but received no reply, within second the aircraft disappeared from radar.

On Jan 12th 2021 the Ministry reported the aircraft had last undergone examination for airworthiness in November 2020 and had received a certificate of airworthiness until Dec 17th 2021 having met all conditions of airworthiness. The Ministry also followed up with Airworthiness Directive AD 2020-14-03 released by the FAA on July 24th 2020 regarding fatigue cracking on the left nacelle support overwing fitting flange fastener hole, and ensured within the November 2020 examination that this AD had been followed. The Ministry stated: "it was confirmed that the Sriwijaya Air SJ 182 aircraft was in an airworthy condition before flying."

In the evening of Jan 12th 2021 the Ministry of Transport reported one of the black boxes was recovered by Navy divers and taken ashore. The black box was subsequently identified as the flight data recorder. The read out of the FDR is expected to take between 2 and 5 days.

Basarnas reported they have deployed resources to the crash site and at the moment focus on locating the aircraft, hoping to be able to establish the position of the aircraft by monring of Jan 10th 2021. Several pieces of debris have been recovered already, however, it has not yet been established they are from the aircraft. The ELT transmitters of the aircraft did not and do not transmit any signals.

On Jan 10th 2021 Rescue and Recovery Services found additional body and wreckage parts, amongst them a part of about 1 meter/3 feet length. Signals believed to originate from the pingers of the black boxes were located at two locations, these signals are going to be further investigated.

On Jan 10th 2021 Basarnas reported a specialist research ship is being dispatched to investigate the ping signals and recover the black boxes. The commander of the ship believes they have successfully determined and marked the position of one of the black boxes. There is hope that the black box can be recovered until evening of Jan 10th. Ships and divers recovered body parts, clothings of victims and metallic pieces amongst them pieces of the fuselage. Body parts as well as debris from the crash site were handed over to local authorities for further handling. In the evening (local time) Basarnas stated: "Basarnas and KNKT to find the exact coordinates of the 2 blackboxes. The two aircraft blackbox emergency signals are believed to have been detected, within 150 to 200 meters of the crash site."

On Jan 11th 2021 Basarnas stated they are still looking for the black boxes, top priority is still on recovering victims however. They believe divers have located the shattered main wreckage buried in mud on the sea floor at a depth of 23 meters.

On Jan 12th 2021 Basaranas reported multiple bags with human remains and aircraft debris were handed over to authorities. Ships with cranes are being brought in to lift larger pieces of the wreckage from the sea floor.

On Jan 13th 2021 Basarnas reported recovery works have been suspended temporarily due to the weather conditions and 2.5m waves at the crash site.

On Jan 14th 2021 Basarnas reported the search for the cockpit voice recorder (CVR) is still ongoing with the assistance by an underwater robot. 34 locations of aircraft debris have been located, one of them is assumed to be the cockpit, another one the tail of the aircraft. The search is still hampered by rain and winds of 20 knots.

On Jan 15th 2021 the Indonesian Navy reported that the pinger of the CVR was found and recovered, however, the CVR's memory unit is still missing. The search for the memory unit is still ongoing.

The airline stated they are in contact with aviation authorities and seeking more information. A statement will be issued once all necessary details have been established.

Singapore have offered assistance for the search for the black boxes, which has been accepted. The US NTSB have accredited a representative who joins the investigation.

On Jan 12th 2021 the KNKT stated according to radar data the aircraft reached a maximum of 10900 feet MSL and appeared to be intacted until hitting the water being capable of transmitting data. The KNKT suspects the engines were running until impact with water based on these data. The positions of the blackboxes have been estimated based on the receiver pinger signals, a team of divers is searching the estimated position, however, have not yet found the blackboxes until afternoon of Jan 12th 2021 (local time).

In the evening of Jan 12th 2021 KNKT confirmed that the chairman of Basarnas handed the flight data recorder (FDR) over to KNKT.

A passenger booked onto the crashed flight reported, that he had to miss the flight due to his Covid-19 PCR Test results not yet having arrived. Only after the aircraft had already departed the (negative) test results arrived which would have permitted him to board the flight.

Residents of the islands nearby (Thousand Islands) were out on the sea in two boats when they heard two explosions, then found debris afloat at the sea. It was raining at that time. The residents returned one of the boats to their islands about 2 hours later and reported to police. The other boat is still at the scene holding position using an anchor. Thesse residents have so far recovered seats, cables, pockets and jeans.

The captain of a ship with 28 crew, that was located about 6nm from the impact site near Lancang Island, reported they were observing an object fall into the waters and set course towards the site. They found flight jackets, body parts and debris of an aircraft. The ship is currently holding position about half a mile off the observed crash site until rescue and recovery services (of Basarnas) arrive. The water is about 15 to 16 meters deep at the crash site.

According to ADS-B data the aircraft had departed Soekarno's runway 25R at 07:36Z, was climbing through 10,600 feet at 284 knots over ground at 07:39:50Z about 11nm north of Soekarno Airport and was at 07:40:11Z at 1400 feet at 307 knots over ground about 1.6nm northnortheast of that position (average sink rate 26,300 fpm).
