Overview
- Boeing told operators last month about a flight‑management software flaw that can disable automated vertical‑navigation during a go‑around and said engineers are developing a permanent update.
- The Federal Aviation Administration has opened a formal Corrective Action Review Board to assess Boeing’s findings and will review the company’s proposed software fix.
- Several major U.S. carriers have declined deliveries of new MAX jets with the affected software and asked for earlier versions while they check their fleets.
- It remains unclear how many in‑service MAX aircraft have the problematic versions because airlines are not required to notify Boeing when they install software updates.
- The issue could affect certification and delivery timing for the Max 7 and Max 10 and comes against a history of scrutiny after the 2018–19 MAX crashes and later manufacturing incidents.
