Aviation authorities have concluded that strange metal pieces found at Hanoi's Noi Bai International Airport since late April were added to cargo transport dollies by the dolly maker to meet weight requirements.
A Dan Tri newspaper report Thursday quoted a source from the Vietnam Civil Aviation Authority as saying 52 kilograms of the metal pieces and small iron balls had been added to 34 dolly trailers used to transport cargo to and from aircraft in order to meet weight specifications in the bidding contract to supply the dollies.
The agency has asked the Vietnam Electromechanical and Construction Company based in Hanoi, which made the trailers, to fix them so that they "truthfully" meet the design requirements.
It has also asked the company to do its own investigation and punish individuals responsible for using the metal pieces to add weight to the trailer.
There was no explanation as to why the company itself was not being held responsible for actions that aviation inspectors have said undermined airport safety.
Many triangular metal pieces with three- to five-centimeter sides and half a centimeter thickness, had been seen around the cargo loading area of the airport since late April,and similar ones were found on May 8 in the dollies.
They had fallen out of holes at the bottom of the trailers, which were managed by Hanoi Ground Services Company. The bottom was covered, but the covers had worn out and the pieces have been falling out through holes.
The Noi Bai airport is using 816 dollies produced by the same company.
