Heavy rain and maintenance lapses triggered ceiling leaks that disrupted KLIA’s check-in area.
A dramatic ceiling leak at Kuala Lumpur International Airport Terminal 1 (KLIA1) on Nov 14 forced the temporary closure of two check-in counters, after rainwater gushed down from the roof due to a contractor’s failure to follow basic safety procedures.
Heavy Rain Triggered the First Signs of Trouble
The incident occurred at 4.14pm on Nov 14, when exceptionally heavy rain hit the KLIA area. Footage circulating online showed water pouring down a column inside the departure hall, soaking the floor near check-in counters K and L. Similar leaks appeared above a café and around a passenger lift, prompting immediate clean-up operations.
Check-In Counters Closed as Teams Contained the Leak
Malaysia Airports confirmed that the affected zone was secured quickly and that water was fully cleared within 1½ hours. Counters K and L reopened soon after critical systems were inspected and deemed safe. Importantly, key airport operations—including baggage handling, passenger processing, terminal movement, and aerotrain services—remained unaffected.

Investigation Revealed a Serious Contractor Oversight
A detailed investigation found that the leak was not caused solely by extreme weather. Maintenance works had been ongoing as part of a year-long roof repair and waterproofing project launched in April 2025. Workers had sealed several rooftop drainage channels using plywood boards. When lightning activity intensified, they were ordered to evacuate the rooftop immediately.
Plywood Boards Left Behind Caused the Dangerous Overflow
In the rush to leave the area, the contractor failed to remove the temporary plywood covers. This blocked one of the drainage systems, preventing rainwater from flowing off the roof. The accumulating water eventually found its way through the ceiling, creating the dramatic “waterfall” effect captured in viral videos.
Malaysia Airports Calls Error ‘Unacceptable’
Malaysia Airports described the oversight as an “unacceptable lapse in basic work procedures,” adding that firm action will be taken against the contractor. It has directed the firm to introduce immediate improvements, including mandatory weather checks before rooftop activities and enhanced emergency protocols for suspending work during unsafe conditions.

Safety Advocates Demand Stronger Audits Ahead of 2026 Tourism Push
Malaysian public safety advocate Lee Lam Thye urged Malaysia Airports to conduct more frequent and thorough safety audits ahead of Visit Malaysia 2026. He warned that recurring infrastructure failures could damage Malaysia’s reputation, shake public confidence in KLIA as a major travel hub, and potentially affect tourism and airline performance.
This incident highlights the crucial role of contractor discipline and infrastructure resilience across key regional transport hubs. For travellers and businesses in Indonesia, Singapore, and the wider region, KLIA’s response and corrective measures will be closely watched as Southeast Asia prepares for growing tourism demand in 2026.
