The pilot-in-command of Air India’s Phuket-Delhi flight, which experienced a sudden 300-foot altitude variation on August 4, tested positive for marijuana in a confirmatory drug test.
The pilot told AAIB that he had been taking medication over sleep difficulties as the investigation into the incident continued.
The government has asked Air India to take responsibility for safety oversight, while AAIB continues examining the technical, operational, medical and human factors involved.
