IMPACT REVISED DOWN
At first, airlines struggled to gauge the impact since the blanket alert lacked affected jets’ serial numbers. A Finnair passenger said a flight was delayed on the tarmac for checks.
Over 24 hours, engineers zeroed in on individual jets.
Several airlines revised down estimates of the number of jets impacted and the time needed for the work, which Airbus initially pegged at three hours per plane.
“It has come down a lot,” an industry source said on Sunday, referring to the overall number of aircraft affected.
The fix involved reverting to an earlier version of software that handles the nose angle. It involves uploading the previous version via a cable from a device called a data loader, which is carried into the cockpit to prevent cyberattacks.
At least one major airline faced delays because it lacked enough data loaders to handle dozens of jets in such a short time, according to an executive speaking privately.
UK’s easyJet and Wizz Air said on Monday they had completed the updates over the weekend without cancelling any flights.
JetBlue said late on Sunday it expects to have completed work to return to service 137 of 150 impacted aircraft by Monday and plans to cancel approximately 20 flights for Monday due to the issue.
SOME OLDER A320 JETS NEED NEW COMPUTER, NOT RESET
Questions remain over a subset of generally older A320-family jets that will need a new computer rather than a mere software reset. The number of those involved has been reduced below initial estimates of 1,000, industry sources said.
Industry executives said the weekend furore highlighted changes in the industry’s playbook since the Boeing 737 MAX crisis, in which the US planemaker was heavily criticised over its handling of fatal crashes blamed on a software design error.
It is the first time Airbus has had to deal with global safety attention on such a scale since that crisis. CEO Guillaume Faury publicly apologised in a deliberate shift of tone for an industry beset by lawsuits and conservative public relations. Boeing has also declared itself more open.
“Is Airbus acting with the Boeing MAX crisis in mind? Absolutely – every company in the aviation sector is,” said Ronn Torossian, chairman of New York-based 5W Public Relations.
“Boeing paid the reputational price for hesitation and opacity. Airbus clearly wants to show … a willingness to say, ‘We could have done better.’ That resonates with regulators, customers, and the flying public.”
