Mumbai: Mumbai’s Chhatrapati Shivaji Maharaj International Airport (CSMIA) will temporarily close both its primary and secondary runways on May 8, 2025, from 11 am to 5 pm, as part of its annual pre-monsoon maintenance program. This essential safety measure, conducted every year under the airport’s “Monsoon Contingency Program,” is designed to prepare the airport’s infrastructure for the challenges of Mumbai’s intense rainy season.
What Happens During the Shutdown?
During this six-hour window, all flight takeoffs and landings will be suspended while expert teams carry out:
- Thorough runway inspections to detect and repair any surface wear, cracks, or damage caused by daily operations.
- Drainage system checks and upgrades to prevent waterlogging and flooding during heavy monsoon downpours.
- Maintenance of runway lights and markings to ensure visibility and safety for aircraft in adverse weather.
Advanced technology and experienced engineers will oversee the process, aiming for timely and effective completion before resuming normal operations.
Advance Notice and Passenger Advisory
CSMIA issued a Notice to Airmen (NOTAM) six months in advance, allowing airlines to adjust schedules and minimize passenger disruption. Despite this, travelers flying to or from Mumbai on May 8 should:
- Check flight status with their airline or on flight-tracking platforms for updates or changes.
- Contact the airport’s 24/7 helpline for assistance with rebooking or travel queries[2].
- Plan for possible delays or rescheduling during the maintenance window.
Why Is This Maintenance So Important?
Mumbai Airport is India’s second-busiest, handling nearly 900 flights and millions of passengers every day. The annual pre-monsoon maintenance is vital for:
- Ensuring safe takeoffs and landings during Mumbai’s notoriously heavy rains.
- Maintaining world-class safety standards and operational reliability throughout the year.
- Preventing disruptions caused by runway flooding or surface damage during the monsoon.
Officials emphasize that this proactive approach is crucial for keeping one of India’s most important air travel hubs running smoothly, especially during the challenging monsoon months.
