The Federal Aviation Administration has ordered US airlines to quickly fix a safety issue on certain Airbus A320 family jets after a JetBlue A320 suddenly dropped in altitude and diverted to Tampa in October. Regulators say a recent software change in the elevator and aileron computer can, in rare cases, let intense solar radiation corrupt flight control data and trigger brief uncommanded pitch changes. The FAA’s emergency directive mirrors Europe’s order and requires affected A319, A320 and A321 aircraft to install a software rollback or updated version before carrying passengers.
By today, US airlines say they are essentially done. American Airlines, the largest A320 operator, says all 209 of its affected jets have now been updated and are back in normal service after Tech Ops teams worked through the night. Delta reports it has fully complied with the directive on its A321neos with no schedule impact, and United says the same for the six aircraft in its fleet that needed the change, with only minor delays along the way.
JetBlue, the carrier involved in the original incident, has been among the most affected, canceling about 70 flights on Sunday as it cycled the last of its A320 and A321 jets through the fix, while Spirit, Frontier and other A320 operators report they are wrapping up remaining work between flights and overnight. For travelers, that has meant scattered delays, aircraft swaps and some cancellations over a busy holiday weekend, but regulators and airlines say the heavy lifting on the recall is now largely behind them and the software gap tied to solar radiation is closed on almost all US Airbus narrowbodies.
