Boeing conducts final test flight of 737 MAX with software fix

WASHINGTON: 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 last year and in March respectively, killing nearly 350 people in total.

In both cases, the planes nosedived shortly after takeoff, signalling a problem in a system that was deployed to correct for an aerodynamic issue that tended to cause the plane’s nose to pitch up.

“More than 85 per cent of the 50-plus MAX operators around the globe also have had the opportunity to see the update in action during simulator sessions,” added Muilenberg.

All 737 MAX aircraft have been banned from the world’s skies since days after the Ethiopian Airlines crash on March 10.

All the Boeing 737 Max of SpiceJet will be grounded before 4 pm on Wednesday. However, flight tracking sites showed several SpiceJet B737 Max were still operating flights on Wednesday morning. Jet Airways has five B737 Max but they are on the ground for a very long time, much before Sunday’s crash of Ethiopian, due to non-payment of lease rentals.

The Federal Aviation Administration on Tuesday said a portion of the proposed modifications were “operationally suitable” but said it would not rush towards approval.
