Airbus A320 Software Glitch Triggers Alerts; IndiGo, Air India Brace for Disruptions

Flight schedules of major Indian carriers — including IndiGo, Air India and Air India Express — may face delays and cancellations as airlines begin addressing a potential flight-control software issue in Airbus A320 family aircraft. The alert follows an incident earlier this month in which 15 passengers aboard a JetBlue-operated A320 were injured after the aircraft suddenly lost altitude and made an emergency landing in Florida.

Airbus SE has informed operators that over half of its active A320 jetliner fleet will require a software update. Indian carriers operate about 560 A320-family aircraft, of which more than 200 will need software changes or hardware adjustments, sources told PTI.

Operational Impact

With aircraft undergoing mandatory updates, several planes will be temporarily grounded, leading to expected operational disruptions. The A320 family includes the A319, A320 (ceo and neo variants), and A321 (ceo and neo).

Indian airlines have begun notifying passengers:

• IndiGo said it is coordinating with Airbus and working to minimise disruptions during inspections.

• Air India Express said it has taken “immediate precautionary action,” warning of potential delays or cancellations despite most of its fleet being unaffected.

• Air India said the directive would require realignment on part of its fleet, causing longer turnaround times and delays.

What Airbus Reported

Airbus said the issue appears linked to “intense solar radiation,” which may corrupt data used by flight-control systems. The company estimates more than 6,500 jets globally could be affected. Importantly, the update must be completed before the aircraft’s next scheduled flight, according to its advisory.

The A320 family is one of the world’s most widely used single-aisle aircraft and a direct competitor to Boeing’s 737 series.

DGCA Issues Mandatory Order

India’s aviation regulator, the DGCA, has issued a directive instructing operators of Airbus A318, A319, A320 and A321 aircraft to fly only those jets that comply with the required modification or applicable airworthiness directives.

The notice states that no aircraft covered by the mandatory modification criteria may operate until the software fix or inspection is completed. Airlines have been asked to confirm compliance as per airworthiness procedures.
