Mumbai’s Chhatrapati Shivaji Maharaj International Airport (CSMIA) resumed operations on Thursday evening after being closed for six hours, from 11 am to 5 pm, for scheduled maintenance.
The maintenance focused on CSMIA’s primary runways—RWY 09/27 and RWY 14/32. During this time, all flight operations were paused to allow for thorough inspections and necessary repairs.
A Notice to Airmen (NOTAM) had been issued six months prior to inform airlines and stakeholders, allowing them to adjust schedules and minimize disruptions. This proactive measure helped prevent significant flight delays or cancellations.
The post-monsoon maintenance is a crucial part of CSMIA’s commitment to operational safety and efficiency, particularly after Mumbai’s heavy rains. Key activities included installing runway edge lights at the RWY 14/32 intersection, clearing debris from underground ducts beneath RWY 09/27, and verifying the strength of the Runway End Safety Area (RESA) for both runways.
In addition, more than 5,000 ground lights were inspected, along with essential systems like drainage, chambers, and cables that support lighting, IT, and navigational aids, according to an airport representative.
The airport’s engineering and airside teams also carried out detailed inspections of the runway surfaces, addressing any wear and tear caused by the monsoon season to ensure they are ready for future operations.
This maintenance ensures CSMIA is prepared for the busy festive and winter travel season ahead. The airport resumed full operations promptly after 5 pm, an official confirmed. Prioritizing preventive upkeep like this helps safeguard the infrastructure of one of India’s busiest airports, which serves millions of passengers each year.
