US regulator finds Boeing 737 MAX software bug ‘not a safety concern’

On October 3, the Federal Aviation Administration (FAA) stated that a software bug found in the cockpit of Boeing's 737 MAX 10 aircraft does not pose a safety concern. The malfunction could potentially disable an automated navigation feature when planes change their approach to landing.

The FAA's investigation board concluded that the issue does not pose a safety concern because pilots maintain complete control over the aircraft, and indications for the crew are clear and unambiguous. The agency emphasized that they will reassess their stance if new information arises regarding the bug.

As a result, Boeing will dispatch a notice to airlines outlining the issue and instructing employees on identifying and responding to the situation if it occurs. The company reaffirmed its commitment to working with the FAA while engineers develop the next software update.

Boeing disclosed on Monday that it had informed all 737 MAX 10 operators about the software issue, which may prevent pilots from accessing automated flight guidance during a specific landing scenario. The company added that it is collaborating with airlines to create a procedure enabling pilots to re-establish automated flight guidance in case the glitch occurs.

Despite the FAA's review, neither the regulator nor Boeing disclosed whether the certification process for the 737 MAX 10 would be reinstated. The model is the final of four 737 MAX planes to receive regulatory approval for commercial operation. FAA Administrator Bryan Bedford affirmed that the certified MAX planes are safe but stated that the 10th model will be delayed until the issue is satisfactorily addressed.
