Air India Pilot Drug Test Rules Exposed After AI2379 Incident

Core News & Key Facts

The Air India AI2379 incident has drawn attention to India’s rules governing psychoactive-substance testing of pilots. The Airbus A320, registered as VT-EXO, was flying from Phuket to Delhi on August 4 when it suddenly lost around 300 feet of altitude during cruise. The aircraft later stabilised and landed safely in Delhi.

Twenty people, including passengers and cabin crew members, were reported injured in the incident. The Aircraft Accident Investigation Bureau is investigating the occurrence, which the government has described as a serious incident.

Following the event, both pilots underwent psychoactive-substance screening. The pilot-in-command’s initial test reportedly returned a non-negative result for cannabis or marijuana and required confirmatory testing. He was removed from flying duties while the process was underway.

The key issue is why the pilot was not subjected to a similar psychoactive-substance test before the flight.

Context & Official Statements

The explanation lies in the distinction between India’s pre-flight alcohol testing system and its separate psychoactive-substance testing framework.

The relevant Directorate General of Civil Aviation regulation, Civil Aviation Requirements Section 5, Series F, Part V, does not require a urine-based psychoactive-substance test before every flight. Its provisions allow testing post-flight, post-shift or during the duty period. The rules also state that a pre-flight testing requirement for psychoactive substances would be introduced in due course.

Under the existing framework, scheduled commercial operators must conduct random psychoactive-substance testing among flight crew members. The programme is required to cover at least 10% of employees in a year, with selection designed to give employees an equal chance of being tested.

Testing is also prescribed in circumstances including pre-employment, training, follow-up of confirmed cases and other specified situations.

This differs from the breathalyser regime for alcohol, under which aviation personnel undergo pre-flight testing. Psychoactive-substance screening involves urine testing for a specified group of substances, including cannabis and other controlled or potentially impairing substances.

Impact & What to Expect Next

The AI2379 case has raised questions about whether India's existing testing framework should be strengthened. The Civil Aviation Ministry has reportedly asked the DGCA to review the rules while examining protocols followed in other countries.

A non-negative initial screening result does not itself constitute a final confirmed positive result. The regulatory process provides for confirmatory testing, with employees removed from safety-sensitive duties while the result is being established.

The supplied report says the subsequent confirmatory test reportedly detected marijuana or cannabis. It also states that the pilot has denied wrongdoing.

The existing rules provide a graduated response after a confirmed positive result, including medical evaluation and rehabilitation measures. Further confirmed positives can lead to licence suspension or cancellation under the prescribed framework.

For now, the central regulatory point remains unchanged: DGCA rules do not mandate a psychoactive-substance drug test for every pilot before every flight. The investigation into AI2379 and the ministry’s review of the testing framework could determine whether that position changes.
