COMPREHENSIVE ACTION PLAN TO RESTORE RELIABILITY IN KLIA AEROTRAIN SYSTEM

SEPANG - Malaysia Airports has initiated a comprehensive action plan within the Defects Liability Period (DLP) to enhance the reliability in the Aerotrain system at KL International Airport (KLIA) through a methodical and structured approach that will further strengthen system performance and resilience towards the conclusion of the DLP.

With the concurrence of the Ministry of Transport (MOT) and the acknowledgement of the Land Public Transport Agency (APAD), the plan will commence from 15 November onwards. Comprehensive inspection, testing and where required, rectification across the overall system and its critical subsystems will be conducted from 9.00 PM to 7.00 AM daily.

During this period, full bus services will be deployed to ensure uninterrupted connectivity between the main terminal and the satellite buildings. For greater passenger comfort, more flight departures and arrivals will take place at the main terminal building to reduce the need for transfers.

Developed in collaboration with appointed contractors and consultants, the action plan comprises three structured stages to address system vulnerabilities in a systematic and verifiable manner. Each stage provides progressive assurance of the system’s reliability and performance.

The first stage focuses on identifying and rectifying system imperfections, preventing recurrence of past issues and implementing planned technical and software upgrades along with detailed inspection of the complete train system. 

The second stage centres on validation, involving simulated operational testing and targeted enhancements such as software updates, component recalibration and real-time stress testing to reinforce system robustness. 

The final stage will involve monitored trial operations to confirm system readiness and operational stability before full service resumption. For further assurance, an independent assessment will be undertaken to conduct comprehensive technical and operational audits, while APAD will perform a formal safety inspection upon completion of the plan. 

Managing Director of Malaysia Airports, Dato’ Mohd Izani Ghani, said the plan represents a decisive step forward in restoring public confidence through a structured approach, regulatory collaboration and open communication. 

“Our focus remains on ensuring that the Aerotrain delivers the reliability and safety expected at an international gateway such as KLIA. This plan allows us to systematically address the root causes of past disruptions while reaffirming our commitment to passenger safety and service excellence,” he said. 

Malaysia Airports will continue to work closely with MOT, APAD and all relevant stakeholders throughout the implementation period, providing regular updates to ensure clarity, accountability and sustained public confidence in the KLIA Aerotrain system. 

Since resuming operations on 1 July 2025, the Aerotrain system at KLIA has served about seven million passengers and completed over 53,000 return trips, recording an Operational Service Availability (OSA) of 98.41%.
