A technical issue was reported on IndiGo flight 7253 operating from Madurai to Chennai on Friday after the captain observed a crack on the aircraft's windshield, according to sources.
The crack was noticed by the pilot as soon as it appeared on the aircraft's windshield. The airline's engineering team has been alerted and is carrying out a detailed inspection of the aircraft. Preliminary findings indicate that the crack is external.
On receipt of the information, arrangements were made at the airport and the plane landed safely, they said.
The aircraft was taken to a separate bay (Bay No. 95) for parking, and passengers were later safely disembarked. Currently, arrangements are being made to replace the windshield.
Due to the incident, the flight's return journey to Madurai has been cancelled, they added.
Meanwhile, IndiGo in a statement to PTI did not mention the cracks in the windshield and only said the aircraft had been grounded for "maintenance requirement".
"A maintenance requirement was noticed on IndiGo flight 6E 7253, operating from Madurai to Chennai on October 10, 2025, before landing at its destination", an IndiGo spokesperson said.
"Following standard operating procedures, the aircraft landed safely in Chennai and will resume operations only after necessary checks and clearances," the statement added.
