The Wall Street Journal, citing documents from the company, reported that Boeing has discovered a previously unknown software bug in its 737 MAX aircraft. This glitch could cause an automated navigation 'feature' to fail on landing.

Report said that the issue was caused by a software update in the cockpit and could occur when crews change their flight plan after a missed landing.

Boeing, when asked for comment, said that it had informed 'all 737 operators' last month of the software problem under which pilots could not?have access to automated flight guidance in a certain landing scenario.

Our engineers are working on a software update to 'permanently address the issue. Boeing stated in an email that engineers were working on a permanent software update.

The Federal Aviation Administration (FAA) said that it was aware of a possible issue with a software update to the flight computers in certain Boeing 737 MAX aircrafts, and worked closely with Boeing as well as the airlines.

The FAA issued a statement saying that it would convene a Corrective Action Review Board if a safety concern was identified.

Boeing has come under heavy regulatory and safety scrutiny over the past few years, following two 'fatal 737 MAX crash incidents in 2018 and 2019, which led to a 'worldwide grounding of the aircraft. Also after a cabin panel blew out mid-air on a brand new Alaska Airlines MAX 9 in 2018.

Southwest Airlines and 'United Airlines' have requested that Boeing not deliver new 737 MAX aircraft with the affected software, and instead request an earlier version.
