Six residential houses adjacent to the southern boundary of Tribhuvan International Airport have been deemed to be too close to the airport for safety reasons while four others are found to be in critical zone, according to a report prepared by Kathmandu Metropolitan City.

A technical team under KMC engineer Bir Bahadur Khadka came to the finding after conducting an obstacle survey at Palpakpot, Koteshwor in KMC Ward no 35, which lies on the southern end of TIA.

Among the buildings in the area, west of Pespicola-Jadibuti road, six were found to be on obstacle limitation surface, an area beyond the boundary of the aerodrome that must be protected from obstacles so that aircrafts can conduct safe takeoff and landing.

Likewise, four buildings were found to be on the critical zone, meaning that no further physical structure can be added to them. Rest of the buildings have been cleared by the Khadka-led committee.

Earlier, people living in the area had filed a complaint at parliamentary development committee after Civil Aviation Authority of Nepal had decided to reacquire 149 ropanis of land eight years after the owners were permitted to build houses on their plots. Caan’s move was aimed at constructing drainage and extending airport perimeter for preventing construction of houses on the southern side of the airport for air safety.

KMC has not yet officially decided the fate of the buildings that have found to be threatening air safety but sources say they will most likely be demolished.
