All Indian Airline Pilots to Undergo Drug Testing
The Directorate General of Civil Aviation (DGCA) has directed airlines to conduct one-time psychoactive-substance tests for all pilots, significantly expanding India’s existing drug-testing regime for flight crews.
The testing exercise is already underway and has to be completed by July 31, 2027, according to officials. The move follows the August 4 Air India Phuket-Delhi flight incident, in which the pilot-in-command subsequently tested positive for a psychoactive substance.
What Happened on the Air India Flight?
The Air India Airbus A320 was flying from Phuket to Delhi on August 4 when it suffered a sudden loss of pressure in all three hydraulic systems while cruising at around 36,000 feet.
The hydraulic failures caused the autopilot to disengage and triggered a brief stall warning. The aircraft experienced an altitude upset, initially gaining about 372 feet before dropping approximately 292 feet from its assigned flight level.
The incident injured 24 people, including passengers and crew.
The Aircraft Accident Investigation Bureau (AAIB) later reported that the pilot-in-command had tested “non-negative” for a psychoactive substance in a confirmatory test. The bureau called the finding a serious concern and urged the DGCA to take appropriate action. The investigation has not established that the substance use caused or contributed to the aircraft’s altitude upset.
Air India Terminated the Pilot
After the AAIB report was released, Air India said it had terminated the pilot’s employment with immediate effect under its zero-tolerance approach to violations involving safety, fitness or regulatory requirements.
The airline had already begun its own broader testing programme, covering pilots across Air India and Air India Express.
Existing Rules Test 10% Each Year
Under the existing DGCA framework, airlines are required to conduct random psychoactive-substance tests on 10% of pilots and air traffic controllers annually, along with testing requirements covering other safety-sensitive personnel.
The new one-time exercise therefore represents a substantial expansion in the number of pilots being tested.
Officials have indicated that testing across airlines has already started.
Government Considering Annual Testing
Civil Aviation Minister K. Rammohan Naidu has also said the government is working on stricter rules for testing pilots for psychoactive substances.
The DGCA is expected to finalise a draft amendment to the drug-testing rules by the end of September. The proposed framework could move India towards more comprehensive and regular testing rather than relying primarily on the current random-testing system.
What Happens If a Pilot Tests Positive?
Under existing procedures, a positive screening result leads to further testing and medical review, including checks to determine whether a result could have been caused by legitimate medication.
A pilot who tests positive is removed from flying duties while the result is confirmed and the case is reviewed under the applicable regulatory framework.
The stricter approach is intended to ensure that pilots operating commercial aircraft are fit to fly and are not impaired by psychoactive substances.
A Wider Aviation-Safety Push
The DGCA’s decision comes at a time of heightened scrutiny of aviation safety in India. The regulator’s focus is not only on individual pilots but also on strengthening systems that identify potential safety risks before they affect flight operations.
The one-time nationwide testing exercise is therefore likely to be followed by broader changes to the rules governing psychoactive-substance testing across the aviation sector.
Summary: The DGCA has ordered one-time psychoactive-substance testing for all airline pilots, with the current exercise to be completed by July 2027. The decision follows the Air India Phuket-Delhi incident in which the pilot-in-command tested positive for a psychoactive substance. India currently requires annual random testing of 10% of pilots, but the government is considering moving towards a stricter, more comprehensive testing regime.
