Jakarta - Lionair's crashed Boeing 737 MAX had problems with unreliable cockpit instrumentation on a previous flight BBC reports.
According to British news agency BBC, the Lion Air's 737 MAX 8 had erroneous data problem from the altitude and speed indicator systems on Sunday (October 28) during the flight from Bali to Jakarta.
Lion Air CEO Edward Sirait confirmed on Tuesday that there had been such difficulties.
But those problems were solved overnight, let's wait for the investigation, Sirait said.
Following the crash with presumably 189 dead on October 29, Indonesia's National Transportation Safety Committee (KNKT) is now investigating the accident. Divers searched for the black boxes of the aircraft in the Java Sea today (October 30).
The BBC quoted an internal report on a flight with the plane on Sunday (October 28). The report states that the Airspeed and the altitude data were unreliable after takeoff. Several versions of the maintenance document are circulating on Twitter.
According to Aviation Safety Network, there were similar problems on Monday as well. ADS-B data from tracking pages logged wild swings between 4,500 and 5,350 feet before the data stream breaks off.
The data grabbed from the flight tracking portal Flightradar24 suggest that the 737 MAX 8 crashed out of 4,850 feet in just 21 seconds. However, this information to be treated with caution," warned former NTSB chief investigator Steve Wallace. It all depends on the flight data and voice recorder now.
Lion Air's 737 MAX 8 (PK-LQP) was delivered to the Indonesian carrier in August 2018.
The plane had crashed into the sea only a few minutes after its takeoff from Jakarta on the way to the neighboring island of Bangka.
The authorities have no hope of finding any survivors. So far, it was known that the flight crew reported an emergency and wanted to return to Jakarta Airport shortly before the contact was lost with the Flight JT610.
