According to sources, rains had led to a pothole on one of the taxiways, forcing the airport authorities to shut the main runway and resulting in delays in aircraft movement.
This was the second time in less than a month that the Mumbai International Airport Limited (MIAL), the GVK-led joint venture airport company, had to shut the main runway, 009/27, for operations.
The runway remained out of use for over three hours on Sunday morning following which the operations were shifted to the capacity-constrained secondary runway -- 14/32.
"As a result, both arrivals and departures were affected with the incoming flights reporting an average delay of two hours, while departures getting delayed by almost an hour till the afternoon," a source said.
However, a spokesperson of the MIAL said the runway closure resulted in a delay of "half-an-hour".
"Runway 009/27 was not available from 6 am due to a pothole between the N1 and N3 runways. Due to the repair work on the taxiway, the secondary runway was put into operations," the spokesperson added.
The traffic at the main runway was finally restored at 10 am.
