Three Aerotrain Incidents Reported at KLIA Terminal 1 Since July 2025

Since its commissioning on July 1, 2025, the aerotrain service at KLIA Terminal 1 has experienced three temporary service disruptions. These incidents occurred on July 12, September 3, and October 15, with all taking place within the contract's defect liability period.
July 12 and September 3 Disruptions Linked to Power Feed Issues

The disruptions on July 12 and September 3 were attributed to a dislodged current collector device (CCD). This component is crucial for the power feed to the aerotrain's guideway. The dislodgement resulted in a loss of power, causing the trains to stop. The primary contractor for the aerotrain and its traction systems, Alstom, was responsible for addressing these specific issues and conducted investigations into their root causes.
October 15 Incident Involved a Power Trip Across Both Guideways

The incident on October 15 was identified as a power trip that affected both guideways of the aerotrain system. This falls under the purview of the IJM-Pestech Joint Venture (IPJV), which is responsible for the power distribution system and associated installation works. MAHB has convened technical meetings with both Alstom and IPJV to expedite corrective measures for these occurrences.
All Incidents Occurred Within Defect Liability Period

Crucially, all three service disruptions took place while the aerotrain system was still within its defect liability period (DLP). This contractual phase means that the contractors, Alstom and IPJV, bear full responsibility for rectifying any issues related to performance and reliability. MAHB has stated its commitment to ensuring these contractors fulfil their obligations.
Aerotrain System Maintains High Operational Availability Despite Incidents

Despite these three disruptions, the aerotrain system has demonstrated a strong overall performance record. Since commencing operations, the system has transported over 5.75 million passengers and completed more than 42,000 trips. This translates to a cumulative operational service availability (OSA) of 99.23%. MAHB has emphasized that no passenger has missed their flights due to these incidents, and passenger flow between the main and satellite terminals has been maintained via shuttle buses.
