Event Summary

A significant number of Airbus A320 family aircraft worldwide, including 338 operated by Indian airlines, require a software upgrade to address a potential flight control issue. This issue, identified by Airbus, is linked to intense solar radiation corrupting critical flight control data, which could lead to uncommanded elevator movements. The European Union — European Union Aviation Safety Agency (EASA) and the India — Directorate General of Civil Aviation (India) (DGCA) in India have issued directives for airlines to install serviceable Elevator Aileron Computers (ELACs) or perform software modifications. IndiGo, India, and Air India — Air India Express have commenced these upgrades, resulting in widespread flight delays and some cancellations, though most upgrades are expected to be completed by November 30. The event highlights a critical safety concern and the proactive measures taken by manufacturers and regulators to mitigate risks, while also causing temporary operational challenges for the affected airlines.
