Understanding the Phenomenon of Subsidence on the Runway

Phenomenon of subsidence caused the delay of Lion Air’s flight, refers to the vertical shift in the surface of the runway. Which can occur due to various factors, including traffic load, weather conditions, and road construction quality. This phenomenon caused a disruption when the aircraft, a Boeing 737-900ER with registration PK-LGW, was unable to take off as scheduled.

The aircraft, carrying 214 passengers and seven crew members, had already positioned itself on the runway and was preparing for takeoff.

I can confirm that the aircraft was safely moved off the runway and is now at the apron for further operational procedures,” said Danang.

No Mechanical Failure Detected in the Aircraft

In terms of the technical inspection, it was confirmed that the aircraft was in a serviceable condition. And also no issues were found that would prevent it from continuing its operations. The incident was not caused by any mechanical failure but rather by the deformation of the runway. As a precautionary measure, the airline followed established procedures to ensure passenger safety and comfort.

Subsidence, in this context, is a natural phenomenon that involves a vertical shift in the surface due to various factors such as traffic, weather conditions, and the quality of the runway’s construction. This phenomenon often results in uneven surfaces, which can not only reduce comfort but also increase the risk of accidents. Furthermore, subsidence can cause damage to the road or runway. Such as cracks or potholes, indicating the need for repairs to prevent further deterioration.

Overall, the incident at Sultan Thaha Airport serves as a reminder of the importance of ensuring that all airport infrastructure meets the necessary safety standards to prevent accidents. The evaluation of the airport’s safety systems will be an essential step in addressing any issues and ensuring that such incidents are avoided in the future.
