PARIS, Dec 1 (Reuters) - Airbus fleets were returning towards normal operations on Monday after the European planemaker pushed through abrupt software changes faster than expected, averting a prolonged crisis over the discovery of a space-related computer bug.
Dozens of airlines from Asia to the United States said they had carried out a snap software retrofit ordered by Airbus, and mandated by global regulators, after a vulnerability to solar flares emerged in a recent mid-air incident on a JetBlue A320.
Wrestling with safety headlines long focused on rival Boeing, Airbus said on Monday that the vast majority of around 6,000 of its A320-family fleet affected by the safety alert had been modified, with fewer than 100 jets still requiring work.
But some require a longer process and Colombia's Avianca continued to halt bookings for dates until December 8. JetBlue said it would cancel 20 flights for Monday.
Sources familiar with the matter said the unprecedented decision to recall about half the A320-family fleet was taken shortly after the possible but unproven link to a drop in altitude on the JetBlue jet emerged late last week.
Shares in Airbus were down 3% after hitting their lowest since October 15, although analysts said the financial impact may be limited. Thales, which supplies the flight computers, lost 2%.
PLANES GROUNDED DURING PART OF THANKSGIVING WEEKEND
Following talks with regulators, Airbus issued its 8-page alert to hundreds of operators on Friday, effectively ordering a temporary grounding by ordering the repair before next flight.
"The thing hit us about 9 p.m. (Jeddah time) and I was back in here about 9:30. I was actually quite surprised how quickly we got through it: there are always complexities," said Steven Greenway, CEO of Saudi budget carrier Flyadeal.
The instruction was seen as the broadest emergency recall in the company's history and raised initial concerns of disruption particularly during the busy U.S. Thanksgiving weekend.
The sweeping warning exposed the fact that Airbus does not have full real-time awareness of which software version is used given reporting lags, industry sources said.
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 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 Sunday it expected 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 how long the generally older A320-family jets that will need a new computer, rather than a mere software reset, will have to remain out of service amid global shortages of computer chips.
Thales on Friday distanced itself from the issue, saying it was not responsible for the software. Jefferies said the cost of replacing hardware on some jets would be limited.
Industry executives said the weekend furore highlighted changes in the industry's playbook since the Boeing 737 MAX crisis, in which the U.S. 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."

A software retrofit is an update or modification applied to existing software systems to improve functionality or address vulnerabilities, often mandated by regulatory authorities.
A safety alert is a notification issued by aviation authorities or manufacturers to inform operators of potential safety issues that require immediate attention or action.
A flight computer is an onboard system used in aircraft to process data related to navigation, flight control, and other operational parameters to ensure safe flight operations.
