Boeing says it has completed 96 flights so far, with a total of 160 hours’ flying time, with its software fix for the grounded 737 MAX.
Boeing says it has completed 96 flights so far that have tested the performance of the grounded 737 MAX with updated software for the flight control system, CNBC reports.
The tests accumulated a total of around 160 hours of flying time with the updated software, Boeing CEO Dennis Muilenburg revealed at the George W Bush Presidential Centre in Dallas.
Muilenburg himself took one of the test flights last week as the company makes progress developing a fix for the aircraft’s MCAS flight control software and improving pilot training.
These are two problems reported to have been behind two disasters five months apart that killed 346 people and grounded the planes worldwide.
“We continue to demonstrate that we’ve identified and met all certification requirements,” the chief executive said.
The company is also keeping airlines updated, allowing representatives – including Bjørn Kjos of Norwegian – into its flight simulators to show them how the alterations in the control system feel in the cockpit.
Boeing says that executives from two-thirds of the 50 airlines with MAX aircraft in their fleets have paid a visit to experience the new software in this way.
“We want everyone to be confident in it and the additional training and educational resources we’re developing and deploying,” Muilenberg said.
He added that the last few weeks have been the most “heart-wrenching” period of his career. Last week he said he was sorry for the lives lost in the two crashes.
The company is expected to submit its fix to the Federal Aviation Administration and other regulators within the next two weeks, CNBC cites insiders as saying. The regulators’ approval will then take several more weeks.
