Boeing Makes Progress on Aircraft Updates Amid Regulatory Scrutiny

Boeing has been making progress on various aircraft updates, but most of them are related to certification and regulatory issues rather than sweeping announcements. The company has completed planned certification flights for its latest models, including the 737-10, which finished its final test flight on July 28, 2026.

The FAA has been closely overseeing Boeing's progress, and the agency recently finalized an airworthiness directive requiring inspections of 471 Boeing 737 MAX aircraft in specified models. This directive is a reminder that certification progress and regulatory scrutiny can occur in parallel when a large aircraft programme is under close oversight.

Boeing is also working on introducing its enhanced Angle of Attack (eAoA) system for the 737 MAX, which will be introduced in production and retrofitted across the in-service fleet. This update could have significant implications for airlines, as they may need to align sensors and software across sub-fleets while updating documentation, maintenance procedures, and training.

The company is also making progress on its 777X programme, with the 777-9 test fleet logging over 4,800 flight hours across roughly 1,700 flights. Boeing continues to target first deliveries of the 777-9 in 2027.
