A Lion Air jet that crashed into the sea off Indonesia last month was not in an airworthy condition on its second-to-last flight, when pilots experienced similar problems to those on its doomed last journey, investigators said on Wednesday.
Contact with the Boeing 737 MAX jet was lost 13 minutes after it took off on Oct. 29 from Jakarta, heading north to the tin-mining town of Pangkal Pinang.
In a preliminary report, Indonesia's transport safety committee (KNKT) focused on the airline's maintenance practices and pilot training and a Boeing anti-stall system but did not give a cause for the crash that killed all 189 people on board.
