The Sriwijaya Air plane had crashed into the sea on Saturday with having 62 people on board.
Officials said that the plane had passed an airworthiness inspection last month.
According to details,Flight SJ182, which was grounded between March and December last year, resumed commercial flights on 22 Dec. Initial findings showed that the aircraft was still functioning and intact before the tragedy happened.
Okky Bisma, a 29-year-old flight attendant on the plane was recognized on Monday by Indonesian police.
Indonesia’s Transport Ministry on Tuesday said the Boeing 737 had been grounded during the pandemic, and passed an inspection on 14 December.
The National Transportation Safety Committee (KNKT) said that preliminary findings showed the aircraft reached the height of 10,900ft (3.3km) at 14:36 local time on Saturday (07:36 GMT), then made a steep drop to 250ft at 14:40, before it stopped transmitting data.
KNKT head Soerjanto Tjahjono added that the plane’s turbine disc with a damaged fan blade had been found – ruling out the theory that the plane exploded mid-air.
“The damaged fan blade indicates that the machine was still functioning when it crashed. This [is] also in line with the belief that the plane’s system was still functioning when it reached 250ft,” said Mr. Soerjanto in a written statement.
Search teams have said that they have identified the position of the plane’s black boxes. They have been putting effort to find it.
However, KNKT on Tuesday said that a device used to locate black boxes had experienced “technical problems or equipment damage”.
Authorities also said that they were waiting for a new “ping locator” to arrive from Singapore.
Black boxes store data about planes and can provide information regarding accident investigations. They are officially known as the flight data recorder and cockpit voice recorder.
