Five Air India pilots, who had tested positive for coronavirus, have now tested negative, an airline source said on Monday.
The results of second round of tests came on Monday evening.
"All our five pilots, who underwent the second test on Sunday have tested negative for the coronavirus infection," the source said.
The five pilots fly Boeing 787 planes.
There was no immediate comment from Air India.
On Sunday, sources said the five pilots tested positive for coronavirus.
"Five Air India pilots have tested positive for coronavirus. These pilots were tested one after one. We suspect it could be a case of faulty testing kit as well," one of the sources had said.
The national carrier, which is operating flights to evacuate Indians stranded in foreign countries, have asked its pilots to undertake coronavirus test before they operate such flights.
