Boeing has conducted a final test flight of a 737 MAX model with an updated anti-stall system prior to its certification by aviation authorities, the aerospace manufacturer has said.
CEO Dennis Muilenberg on Wednesday tweeted a video where he said the test flight was carried out on Tuesday, adding that test pilots have completed 120 flights totalling more than 203 hours of airtime with the software fix for the Maneuvering Characteristics Augmentation System (MCAS).
Investigators have zeroed in on the system as a factor behind the Lion Air and Ethiopian Airlines crashes in October and in March respectively, killing nearly 350 people in total.
