Chinese local media on Wednesday started to question Lindu Airport's construction standards and its ability to accommodate flight landing during the night.
The airport, which started operation in August last year, covers 129 hectares of land in a thickly forested valley.
Its name -- Lindu -- literally means the "capital of woods".
Li Jian, the vice director of the CAAC, said the airport meets all safety requirement upon construction.
"It is no comparison to big airports but the safety standards are guaranteed."
He said the airport is built with the capacity to accommodate flights during the night.
As of Wednesday night, the Lindu airport remains closed.
