Airport firefighting equipment arrived on the scene within 2 minutes of notification and the fire was brought under control within 30 seconds of their arrival . Investigation showed that the cockpit and cabin interior, including seats, rugs, wall and overhead coverings, were severely damaged by fire and excessive heat.
