An investigation into a Thai AirAsia plane that landed on the wrong runway in Bangkok early this month will be completed in 30 days, said a source with the Civil Aviation Authority of Thailand (CAAT).
The probe was launched by the committee on air accidents and incidents under the Transport Ministry.
Thai AirAsia Flight FD3141 from Ranong to Bangkok landed on the wrong runway at Don Mueang airport on May 4. No one on board was injured and the A320-200 had sustained no damage.
The committee is now probing the pilots and will report its findings to the CAAT by early next month.
Pending those results, the CAAT has instructed the airport and airline to furnish their individual reports on aviation safety and submit them to the CAAT.
The authority will review these to check for any potential safety loopholes and figure out a way to plug them, according to the source.
Once the probe wraps up and details of the incident are clarified, the CAAT will determine whether any punishment or legal action is warranted.
The source said the gravity of any punishment meted out would depend on whether the incident stemmed from a deliberate or reckless act.
Apart from the pilots, the air traffic controllers could have potentially been at fault.
