Key Takeaways:

Emergency airworthiness directives (EADs) were issued by EASA and FAA for Airbus A319, A320, and A321 aircraft after an A320 experienced an uncommanded altitude loss, potentially due to a malfunction in the Elevator Aileron Computer (ELAC) system caused by intense solar radiation.
U.S. airlines largely avoided major disruptions, with most carriers like American and Delta completing the required ELAC modifications swiftly, though JetBlue initially faced more significant groundings.
Separately, Airbus also identified a new quality issue concerning metal panels on A320-family jets, attributing it to an unnamed partner, but stated the problem has been contained.

U.S. airlines appear to have avoided major disruptions after the FAA required emergency modifications to about 545 Airbus A319, A320, and A321 models.

Airbus on Friday said that after an A320 altitude-loss event in October, a preliminary analysis found that “intense solar radiation” may have caused a malfunction of the aircraft’s elevator aileron computer (ELAC) system, which uses pilot commands to control elevators and ailerons. That prompted the European Union Aviation Safety Agency (EASA) and FAA to issue emergency airworthiness directives (EADs) grounding certain A319, A320, and A321 models until carriers completed ELAC modifications.
