MUMBAI, May 8 -- The runways at Chhatrapati Shivaji Maharaj International Airport (CSMIA) will be shut for six hours between 11am and 5pm on Thursday to carry out annual pre-monsoon runway maintenance. Passengers flying in and out of the city must check the rescheduled time of their respective flights as disruptions and delays are expected. A Notice to Airmen was issued six months in advance to notify airlines and stakeholders so that flight schedules can be adjusted beforehand. Both runways -- 09/27 and 14/32 -- will be temporarily non-operational during this time. "This annual pre-monsoon maintenance is crucial for preserving the health and longevity of CSMIA's expansive airside infrastructure, covering 1,033 acres. Specialists will inspect runway surfaces for wear and tear, addressing preventive measures for waterlogging to ensure safe landings and take-offs during the monsoon season. CSMIA also leverages advanced technology to monitor the entire maintenance process, ensuring timely execution within the designated six-hour window," a spokesperson of the Mumbai International Airport Limited, said in a statement. This would be the third consecutive day of flight disruptions at CSMIA. CSMIA on Wednesday issued a passenger advisory warning of flight operations impacted due to the closure of certain airports across the country. Thunderstorm led to low visibility and all flight operations were shut down for eight minutes on Tuesday....
