Development of updated software for the Boeing 737 Max has been completed following global grounding of the aircraft after two fatal crashes within five months.
The US manufacturer revealed yesterday that it had flown the 737 Max with updated Manoeuvring Characteristics Augmentation System (MCAS) software for more than 360 hours on 207 flights.
Additional information is being provided to address US Federal Aviation Administration requests that include detail on how pilots interact with the aircraft controls and displays in different flight scenarios.
Boeing will then work with the regulator to schedule its certification test flight and submit final certification documentation.
The company has also developed enhanced training and education materials that are now being reviewed with the FAA, global regulators, and airline customers to support the Max’s return to service and longer term operations. This includes a series of regional customer conferences being conducted around the world.
FAA said earlier this week that it would hold a meeting on May 23 with aviation regulators from around the world to provide an update on reviews of Boeing’s software fix and new pilot training.
A Lion Air 737 Max crashed in Indonesia in October killing 189 people, followed by the Ethiopian Airlines disaster killing all 157 passengers and crew on board
Tui is among worldwide operators suffering the financial pain of the 737 Max grounding, warning earlier this week that it could face a hit of €200 million if the aircraft is still not operating by mid-July, rising to €300 million if not available until the end of the summer.
“We’re committed to providing the FAA and global regulators all the information they need, and to getting it right.
“We’re making clear and steady progress and are confident that the 737 Max with updated MCAS software will be one of the safest airplanes ever to fly.
“The accidents have only intensified our commitment to our values, including safety, quality and integrity, because we know lives depend on what we do.”
