What happened
A surface-protection deviation involving insufficient anti-corrosion primer on forward-fuselage stringers affects approximately 500 A321neos. Operators can accept aircraft and schedule a nine-day repair within two years; Airbus describes the issue as a durability concern rather than an immediate safety risk.
Why it matters: The arrangement preserves near-term capacity but shifts a large maintenance burden from Airbus and suppliers to airline MRO networks.
