CHENNAI: It was late, well past 11 pm on August 11, 2026, when an IndiGo flight coming in from Kolkata ran into trouble just as it was lining up to land. The left engine had developed a snag, and the crew picked up signs of an oil leak too. There were roughly 224 people on flight 6E-723 at the time. In the end, the plane touched down safely at 11:37 pm and nobody was hurt, though the aircraft hasn’t flown a single mile since.
What We Know So Far
- Flight: IndiGo 6E-723
- Route: Kolkata to Chennai
- What went wrong: left engine snag; an oil leak was also reported
- Emergency status: full emergency declared at Chennai airport
- Landing time: 11:37 pm on August 11
- Onboard: somewhere around 224 people, though one report puts the figure at 229 (222 passengers plus 7 crew)
- Injuries: none
- Where’s the plane now: parked at a remote bay, grounded until repairs are done
- Investigation: the DGCA has ordered one
Worth flagging that discrepancy in numbers up front. Some outlets are saying 224 onboard, others 229. IndiGo hasn’t put out an official passenger manifest yet, and until it does, both figures are floating around as unconfirmed.
How Tt Unfolded
The trouble started during the final approach into Chennai the kind of moment where a pilot has only seconds to decide what to do next. The crew noticed the left engine wasn’t behaving, and then came word of an oil leak on top of that. Landing normally, under those conditions, wasn’t something the pilot was willing to risk.
So the call went out to Chennai air traffic control, and the response was immediate. Airport authorities declared a full emergency right there on the runway. That triggers a fairly standard but serious drill: fire engines roll out, ambulances line up, emergency crews get into position, all before the aircraft is even cleared to come down.
For a while, the plane just circled overhead. Passengers would have felt that, the extra minutes in the air while ground teams scrambled to get everything ready below. Once the runway was set and the emergency response was in place, ATC gave the go-ahead. The aircraft landed at 11:37 pm, and everyone got off the plane in one piece.

The Aircraft’s Grounded Now
After the passengers had cleared out, engineers went in to have a proper look at the engine. What they found wasn’t something you patch up overnight the aircraft was declared unairworthy just before midnight and towed to a remote parking bay, where it’ll sit until repairs and inspections are wrapped up. That’s fairly standard practice after any incident involving an engine fault; airlines aren’t going to send a plane back into the sky without knowing exactly what went wrong first.

DGCA Has Opened a Probe
The Directorate General of Civil Aviation is now investigating. These inquiries usually dig into three things: what actually caused the snag and the leak, whether the aircraft’s maintenance history shows anything that should have been caught earlier, and whether the emergency response on the ground followed protocol. Findings from this kind of probe don’t tend to come quickly it could be weeks before there’s anything official.
