JAKARTA—The Lion Air jet that crashed into the Java Sea last month was not in an airworthy condition even on its second-to-last flight, when pilots experienced similar problems to those on its doomed last journey, Indonesian investigators said on Nov. 28.
In a preliminary report, Indonesia’s transport safety committee (KNKT) focused on the airline’s maintenance practices and pilot training and a Boeing Co anti-stall system but did not give a cause for the crash that killed all 189 people on board.
