The Directorate General of Civil Aviation (DGCA) is considering requiring all pilots to undergo at least one random drug test every year, Civil Aviation Minister Ram Mohan Naidu Kinjarapu told reporters on Tuesday, following the Air India Phuket-Delhi flight incident.“But just like I said, DGCA is engaging, and one of the opinions from our side is that everyone has to go through it in the year at a random time,” Naidu said.He said the regulator was consulting stakeholders on existing rules governing substance use and possible changes to ensure a stricter policy in the future.Also Read: Pilots struggled to control Air India's Phuket-Delhi aircraft due to rare malfunction, shows Airbus’ initial assessment“Right now, the rule says 10% across the overall pilot network,” Naidu said, referring to the existing requirement for drug testing.— ANI (@ANI) The minister said any change would need to balance aviation safety with the operational impact on airlines.“There are multiple ways of approaching this dope test,” he said, adding that safety would remain the priority while the operational implications would also have to be considered.Naidu's comments come as the Aircraft Accident Investigation Bureau (AAIB) investigates the Air India Phuket-Delhi flight incident. He said the investigation was underway and that the aircraft's data recorder remained intact and the plane was still in its position.“Because the data recorder and everything is intact, the plane has also been in its position, so I believe that we can expect some preliminary report very early from now,” he said.Also Read: 'Two Air India pilots found non-negative in drug test'The minister did not provide a specific timeline for the preliminary report.Separately, the DGCA's stakeholder consultation is examining how the existing rules on substance use among aviation personnel could be strengthened.Ram Mohan Naidu said the government was looking at different approaches to drug testing, including whether annual random testing should apply across the pilot network, while taking into account both safety requirements and operational considerations.
