Boeing 737 MAX software patch expected before end-March, say sources

Boeing Co plans to release upgraded software for its 737 MAX in a week to 10 days, sources familiar with the matter said. The U.S. planemaker has been working on a software upgrade for an anti-stall system and pilot displays on its fastest-selling jetliner in the wake of the deadly Lion Air crash in Indonesia in October.

Similarities between the flight path in the Lion Air incident and Sunday`s Ethiopian Airlines crash have raised fresh questions about the system, but so far there is no evidence on whether the same software is again a potential issue.

Asked about the timeline, first reported by AFP, a Boeing spokesman referred to a statement on Monday that the upgrade would be deployed across the 737 MAX fleet in the coming weeks.
