The Indonesian jet which crashed shortly after take‑off yesterday had suffered instrument problems the day before.
This is according to a technical log obtained by the BBC.
A technical log from a flight from Bali to Jakarta said an instrument was "unreliable" and the pilot had to hand over to the first officer.
The Boeing 737 airliner crashed into the sea with 189 people on board.
It went down after taking off from Jakarta. There is no sign of survivors.
Rescuers have recovered some bodies and personal items, including baby shoes. Families are being told to go to a hospital to identify the dead.
The incident is reported to be the first major accident involving a Boeing 737 Max ‑ an updated version of the 737.
