Captain Arvind Kathpalia was the director of operations at the national carrier. It was the second time Kathpalia was in trouble over alcohol tests. He was suspended for three months in 2017 for allegedly refusing to take breathalyser tests.
"The privileges of his licence have been suspended for a period of three years from 11.11.2018 as per the provisions of applicable regulations," a spokesperson at the DGCA said in a statement.
On Sunday, he had said that he would contest the results of the tests and claimed he was the victim of internal feuding within the loss-making state-owned airline.
