What Happened
- A fire broke out at Terminal 1 of Chhatrapati Shivaji Maharaj International Airport (CSMIA), Mumbai, on April 9, 2026 at approximately 6:10 PM due to a short circuit in a cable tray and switch box area.
- The blaze was classified as a Level-1 fire and was confined to the ground floor of the terminal structure; both the airport's Aerodrome Rescue and Fire Fighting (ARFF) unit and the Mumbai Fire Brigade responded.
- The fire was brought under control within minutes with no casualties and no disruption to flight operations.
- Thick smoke was visible in the terminal, triggering evacuation procedures.
- The incident temporarily affected internet infrastructure at the terminal but did not impact runway or aircraft operations.

Airports Authority of India (AAI) and Airport Regulation
The Airports Authority of India (AAI) is a statutory body constituted under the Airports Authority of India Act, 1994. It manages civil aviation infrastructure across India and is responsible for safe and efficient air traffic services. AAI operates 137 airports including international, domestic, and civil enclaves.
- AAI was formed by merging the International Airports Authority of India and the National Airports Authority in 1995.
- It functions under the Ministry of Civil Aviation.
- AAI provides Airport Rescue and Fire Fighting (ARFF) services at 66 airports across India.
- Chhatrapati Shivaji Maharaj International Airport (CSMIA), Mumbai is privately operated by MIAL (Mumbai International Airport Ltd), not directly by AAI.
Connection to this news: The fire response at Terminal 1 involved ARFF units whose standards are set by AAI and the DGCA, illustrating the multi-agency framework governing airport safety even at privatised airports.
Directorate General of Civil Aviation (DGCA) and Safety Oversight
The DGCA is the apex regulatory body for civil aviation in India, functioning under the Ministry of Civil Aviation. It exercises regulatory oversight over safety of air transport, airworthiness of aircraft, licensing of pilots and other aviation personnel, and safety of airports. DGCA requires all aerodromes open to public operations to obtain aerodrome certificates and implement a Safety Management System (SMS).
- DGCA issues Civil Aviation Requirements (CARs) — the Indian equivalent of ICAO Standards and Recommended Practices (SARPs).
- DGCA's CAR Section 4 covers aerodrome standards including fire protection categories.
- Airports are classified into ICAO categories 1–10 based on the length and width of the largest aircraft using the aerodrome, which determines the level of fire service required.
- Mumbai's CSMIA is a Category 9/10 airport handling wide-body international aircraft.
Connection to this news: The fire was handled according to ARFF protocols mandated by DGCA, which aligns with ICAO Annex 14 (Aerodromes) standards.
ICAO Annex 14 and Aerodrome Fire Standards
The International Civil Aviation Organization (ICAO) is a UN specialized agency that sets global standards for civil aviation through its Annexes to the Chicago Convention (1944). Annex 14 covers aerodrome design and operations, including rescue and fire fighting requirements. ICAO standards are binding on member states (India is a founding member) and must be incorporated into national regulations.
- ICAO Annex 14 specifies that every aerodrome must maintain an ARFF capability commensurate with the aerodrome category.
- It defines response time objectives: ARFF vehicles must reach any point of the runway within 3 minutes from initial alarm in optimum conditions.
- ICAO distinguishes between "terminal fires" (structural) and "aircraft fires" — separate protocols apply for each.
- India ratified the Convention on International Civil Aviation (Chicago Convention) in 1944.
Connection to this news: The rapid containment of the Terminal 1 fire within minutes reflects ARFF readiness mandated by ICAO standards, though terminal fires (structural) also involve coordination with municipal fire brigades, as demonstrated in this incident.
Disaster Management Framework at Airports
Civil airports in India are required to maintain Airport Emergency Plans (AEPs) under DGCA regulations. An AEP outlines procedures for handling various emergencies including aircraft accidents, bomb threats, hijacking, and structural fires. The National Disaster Management Authority (NDMA) provides overarching guidance while DGCA enforces aviation-specific emergency response requirements.
- Fire incidents at airports are classified into levels: Level 1 (minor, containable by airport resources), Level 2 (requires mutual aid from local fire services), Level 3 (mass casualties, requires full emergency response activation).
- The Mumbai Terminal 1 fire was classified as Level 1.
- All airports above a certain category must conduct mandatory AEP mock drills at least once every two years (DGCA CAR requirement).
Connection to this news: The classification of this incident as Level 1 and its swift containment reflect the tiered emergency response system mandated under India's aviation safety regime.
