Chennai airport declares full emergency after IndiGo flight reports engine malfunction

Chennai International Airport declared a full emergency late on August 11 after an IndiGo flight operating from Kolkata reported a left-engine malfunction while approaching the city.

According to airport officials cited by GoodReturns, the aircraft, operating as flight 6E-723, landed safely despite the technical issue. All 224 passengers and crew members on board were reported safe, and no injuries were recorded.

The incident prompted airport authorities to activate emergency protocols and position rescue personnel, firefighting units and support teams ahead of the aircraft's arrival.

Pilot reported engine issue during final approach

The aircraft was scheduled to arrive in Chennai at around 11.30 pm.

Airport officials said the pilot informed air traffic control about a problem affecting the aircraft's left engine as it neared its destination.

Following the report, Chennai airport initiated a full emergency response, a standard aviation safety measure used when an aircraft experiences a significant technical issue that may require immediate assistance upon landing.

Key details of the incident include:

• Flight: IndiGo 6E-723
• Route: Kolkata to Chennai
• Issue reported: Left-engine malfunction
• People on board: 224 passengers and crew
• Landing runway: Runway 25
• Landing time: 11.37 pm
• Emergency withdrawn: 11.47 pm

The aircraft touched down safely approximately eight minutes after the emergency was declared.

Emergency teams placed on standby

A full emergency declaration enables airports to mobilise specialised response teams and prepare for a range of possible scenarios.

Under such procedures, airports typically deploy:

• Fire and rescue vehicles
• Medical response teams
• Emergency operations personnel
• Airside support units

The declaration also allows air traffic controllers to prioritise the affected aircraft and ensure a clear approach and landing path.

Airport officials said emergency personnel were positioned and ready as a precaution while the aircraft completed its approach to Chennai.

The emergency was withdrawn ten minutes after landing once authorities confirmed the situation had been safely resolved.

Airport operations remained unaffected

Despite the emergency response, airport officials said normal operations continued after the aircraft landed.

There were no reports of prolonged runway closures or wider disruptions to scheduled flight movements.

The incident occurred during the final segment of the flight, giving airport authorities sufficient time to activate response procedures before the aircraft reached the runway.

The successful landing and rapid withdrawal of the emergency status helped minimise operational impact on other flights using the airport.

Aircraft expected to undergo inspection

Following any reported engine-related malfunction, airlines typically conduct detailed technical examinations before returning an aircraft to service.

Such inspections generally focus on:

• The affected engine
• Associated aircraft systems
• Maintenance records
• Potential component failures

The scope of the assessment depends on the nature of the malfunction and findings from engineering teams.

Airport officials have not released further details regarding the cause of the reported engine problem. Any determination on the source of the malfunction would require technical evaluation by maintenance specialists and relevant aviation authorities.

The incident serves as a reminder of the aviation sector's layered safety procedures, where emergency declarations allow airports and airlines to respond quickly to technical issues while maintaining passenger safety as the highest priority.
