A crack in the windshield of an aircraft belonging to the largest domestic airliner, IndiGo, carrying 76 passengers from Madurai was detected by the pilot ahead of its landing at the airport in Chennai on Saturday, authorities said.
The pilot noticed the crack in the front glass and informed the Air Traffic Controller at the airport in Chennai.
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 later safely disembarked. Currently, arrangements are being made to replace the windshield, they said.
The cause of the incident is not yet known, they said.
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.
