US FAA: Boeing 737 MAX software bug poses no safety concern

Federal Aviation Administration'said Friday that a panel of experts determined that a'software glitch in certain Boeing 737 MAX Flight Computers pose no safety concerns, clearing the?way for approval of a broader version?of a bestselling narrow body jet.

This decision will remove a long-delayed obstacle to the certification of the MAX 10 – the largest variant in the 737 MAX Family – which had been delayed by years. This should ease the concerns of airlines who fly the MAX 7 which also uses the same software and was certified by FAA in august.

The FAA stated that the decision by the Corrective action Review Board?that?met in Seattle on?Friday was based on "pilots retaining full control of?aircraft, and the indications given to the flight crew were clear and unambiguous."

The FAA announced earlier this week that it would delay?certification for the MAX 10 until an analysis was completed of the software problem, which could prevent pilots?from?accessing automated guidance during a landing scenario.

Aviation officials believe that the MAX 10 could now be certified by the end of this month. Southwest Airlines could have also been affected by the issue, as the MAX 7 aircraft that was just certified uses the same software. The MAX 10 was also ordered by Alaska Airlines, United Airlines, and other large airlines.

Jefferies stated in a research report that the MAX '10 can be certified by the end of this year. Boeing has estimated nearly 1,500 MAX 10s are on order.

The FAA stated that one software version could increase pilot workload when a pilot "aborts" a landing, then applies power and climbs for another 'landing attempt.

A FAA official stated that Boeing would issue a bulletin on how to recognize the situation and what to do in it. The FAA will then issue a Special Information Bulletin about Airworthiness to US airlines and foreign regulators so they are aware of Boeing’s bulletin.

While the analysis was in progress, major US airlines chose not to use this version of the software.
