Chennai, Aug. 13 – IndiGo flight 6E-723, an Airbus A321neo operating the Kolkata to Chennai route on 11 August 2026, encountered a left engine inoperative condition accompanied by an oil leak during final approach to Chennai International Airport. The technical snag prompted the flight crew to notify air traffic control immediately, resulting in a full emergency declaration at 23:29 IST. Emergency response teams, including fire tenders and medical personnel, were rapidly deployed to ensure readiness for the incoming aircraft carrying 224 passengers and crew members.
The aircraft, registration VT-IMI, executed a controlled priority landing on Runway 25 at 23:37 IST, just seven minutes after its scheduled arrival time. All individuals on board remained unharmed, and the full emergency status was formally withdrawn at 23:47 IST once the situation stabilized. Airport authorities confirmed that normal operations resumed promptly thereafter without broader disruption to Chennai airport traffic.
Following the safe disembarkation of passengers, IndiGo engineers conducted a thorough inspection of the Airbus A321neo involved in the IndiGo flight emergency landing Chennai incident. The aircraft was subsequently declared unairworthy due to the engine issue and grounded pending comprehensive technical evaluation and regulatory clearances. The airline stated that standard operating procedures were followed throughout the event.
This engine failure episode on IndiGo flight 6E-723 highlights the effectiveness of established aviation safety protocols in managing in-flight technical challenges. Detailed post-incident analysis continues to determine the precise cause of the left engine inoperative condition, ensuring the aircraft returns to service only after full airworthiness verification.
