The aircraft made a successful landing in the Tribhuvan International Airport and the situation of flight is normal, said the TIA’s spokesperson Tek Nath Sitaula. The aircraft was diverted from Dhading district after a crew member informed the air traffic control tower in Kathmandu about the manifestation of a spark of fire in the engine, said the airport officials.
