CAAT asks AOT to explain Suvarnabhumi runway damage
AOT blames soft, waterlogged ground and is scanning the surface for spots to repair, mainly turning points, taxiway exits and runway thresholds, rather than resurfacing everything.
Thailand’s aviation regulator has asked Airports of Thailand (AOT) to explain Suvarnabhumi runway damage after a China Airlines jet got stuck on 28 October.
Why it matters: AOT plans repairs at night and says it cannot close the whole runway because of traffic, so night flights are the ones to watch.
The wheels of China Airlines flight CI840 to Kaohsiung got stuck in the runway surface, with heavy rain and groundwater blamed. The Civil Aviation Authority of Thailand (CAAT) has asked AOT for a report on the cause and on how it will prevent a repeat. It also suggested AOT use technology to test the strength of the runway, taxiways and aprons. CAAT said deteriorated construction materials may be a factor, which is not yet confirmed.
AOT said engineering checks found the runway layers sit on soft soil with a high water content, and recent flooding and rain added water near the surface. As an example of the work, AOT cited about 10 nights between 8pm and 6am. It has not announced dates.
Reports did not say whether the aircraft was damaged, anyone was hurt or flights were delayed.
Background Background
Suvarnabhumi has operated for about 20 years. The Civil Aviation Authority of Thailand regulates airport safety and can ask operators for reports after incidents. Airports of Thailand, a listed company, runs the airport and maintains its runways, taxiways and aprons.
What to do If your flight leaves or lands between 8pm and 6am, check its status with your airline before you head to the airport.
