(Bloomberg) -- Delhi Airport has suspended all flights from Terminal 1 after a part of the forecourt’s canopy collapsed early Friday following heaviest one-day June rain in 88 years, killing one person. 

All arrivals and departures from the terminal are being rescheduled until further notice, Delhi Airport said in a post on X. IndiGo and Spicejet, which operate out of Terminal 1, will now use the other two terminals at Delhi airport. 

While the collapse is being assessed, the primary cause seems to be the continued heavy rainfall, Delhi International Airport Ltd., or DIAL, said in a statement.

The India Meteorological Department said that the city’s Safdarjung weather station recorded 228 millimeters (9 inches) of rain in the 24-hour period to 8:30 a.m. local time Friday, the heaviest one-day downpour for June in 88 years. More heavy rains are forecast for parts of Delhi until at least Tuesday, as the monsoon has arrived in the capital, it said. 

One person has died, while eight people have been injured in the incident, said Atul Garg, director of Delhi Fire Services. 

“High-level” Investigation 

Several cars were crushed under the collapsed canopy, which covers the terminal’s drop-off and pickup area. 

A committee has been formed by the airport to investigate the case and will give a report “as soon as possible,” DIAL said. It’s working with all relevant agencies, including Delhi police, India’s top aviation authority DGCA, and the disaster response force, it said. 

Delhi Airport is one of the busiest in the world, handling 72 million passengers in 2023, according to Airports Council International. Terminals 1 and 2 handle domestic passengers, while Terminal 3 handles all international travelers. 

DGCA is carrying out a “high-level” enquiry into the incident, while all other airports will undergo a “detailed structural inspection”, Murlidhar Mohol, India’s junior aviation minister said in an online post. 

The injured person passed away while undergoing treatment in the hospital, Press Trust of India reported earlier, citing police officials. A number of people were injured and promptly provided with medical assistance at the scene, while some were taken to the hospital, India’s civil aviation ministry said in a post on X. 

Compensation of 2 million rupees ($24,000) will be given to the deceased, and 300,000 rupees to injured people, said Ram Mohan Naidu Kinjarapu, India’s aviation minister. 

The incident comes less than four months after Prime Minister Narendra Modi presided over the opening of an upgrade of the terminal, to allow it to handle 40 million passengers a year, up from 17 million previously. 

All up, the airport handled 6.5 million passengers in May across its three terminals, up 8% from a year earlier. 

More than 40% of all flights departing from the three terminals in Delhi have been delayed, while 42, or 11%, of flights have been canceled, as of 2:39 p.m. local time, according to data from Flightradar24.com. 

The airport had previously suspended departures at the terminal till 2 p.m. local time. 

IndiGo, which is operated by InterGlobe Aviation Ltd., separately said it has canceled all flights from the terminal. “This unplanned situation has also led to operations across the network being impacted,” an IndiGo spokesperson said in a statement. 

Shares of GMR Airports Infrastructure Ltd., which is the parent of the Delhi Airport operator, fell as much as 3.5% on Friday.

Separately, a part of the canopy at Jabalpur Airport in central India collapsed Thursday.
