Overview
- The FAA, which announced the review on Monday, said it will decide on 737 Max 10 certification only after a Corrective Action Review Board assesses the newly disclosed software fault.
- Boeing says the bug can make automated vertical navigation (VNAV) unavailable on further approaches after a go‑around, forcing pilots to use a lower automation mode or fly manually until the system is reactivated.
- Boeing told operators about the problem last month, advised crews to follow existing procedures for handling reduced automation, and is developing a permanent software update.
- Major carriers have pushed back: reporting shows some airlines asked Boeing not to accept new aircraft with the current software and to install an earlier or fixed version instead, and it is not yet clear how many delivered Max jets carry the affected build.
- The Max 10’s delayed certification matters commercially because the variant holds roughly 1,400–1,500 orders and any hold or delivery slips could affect Boeing’s backlog and its competition with Airbus while regulators renew scrutiny of the wider 737 Max program.
