India’s aviation regulator has mandated urgent modifications across Airbus A320-family aircraft. This action follows a recent in-flight episode where an A320 briefly experienced an uncommanded pitch-down. Officials noted that the autopilot stayed engaged, the loss of altitude was minimal, and the flight continued normally.
A preliminary assessment by Airbus suggests a possible malfunction in an Elevator Aileron Computer (ELAC). Airbus issued an Alert Operators Transmission (AOT A27N022-25 Rev 00) on 28 November 2025. They advised operators to carry out a software update. Alternatively, operators should replace the affected ELAC units. The European Union Aviation Safety Agency (EASA) also released an Emergency Airworthiness Directive (2025-0268-E) the same day.
The Directorate General of Civil Aviation (DGCA) acted on these advisories. They issued a Mandatory Modification notice on 29 November 2025. This applies to all Indian-registered A318, A319, A320 and A321 aircraft. Around 250 aircraft in India fall under this directive, while nearly 6,000 aircraft worldwide are expected to be impacted.
Airlines begin Rapid Compliance
IndiGo, the country’s largest operator of the A320 family, confirmed swift progress. “We are pleased to confirm that the required actions are completed on 160 aircraft. This was done by 12:00 IST,” the airline said. Inspections on the remaining aircraft are underway. They will be finished within the mandated timeline.
Air India, which operates nearly half of its fleet in A320 variants, is also carrying out updates.
Expert Flags Temporary Travel Impact
Aviation and tourism expert Subhash Goyal is the Chairman of the Aviation & Tourism Experts Committee, Indian Chamber of Commerce. He said the directive could cause short-term disruption.
“Newer aircraft may take a day or two for upgrades, while older jets could take longer. IndiGo and Air India will feel the biggest operational impact. Airlines must collaborate — even sharing vacant seats — to protect passengers from excessive inconvenience and financial strain. A temporary spike in fares is possible as schedules adjust. This is the first known instance where external radiation seems to interfere with flight control systems. The industry is responding on a war footing.”
Despite the challenges, regulators and airlines maintain that safety remains fully under control. The mandated fixes are moving rapidly toward completion.
