DGCA moves to test more than a quarter of India's flight crew for drugs each year

India's aviation regulator is preparing to more than double the share of airline flight crew who must undergo random drug screening each year, a change that would take the mandatory annual sample from 10 per cent of eligible personnel to more than 25 per cent.

News agency ANI reported on 19 August that the Directorate General of Civil Aviation (DGCA) is set to make it compulsory for Indian carriers to randomly test upwards of a quarter of their flight crew every year for psychoactive substances using urine samples. The reporting is sourced to officials rather than to a published civil aviation requirement, and the DGCA had not issued a formal amendment as of Sunday. Several Indian outlets, including Deccan Chronicle and NewsDrum, carried the same account over the following two days.

If the change is notified as described, it would be the most significant tightening of India's crew drug-testing regime since the rules were introduced, and it would push India well past the screening intensity applied in most comparable jurisdictions.

What triggered the review

The move follows the events aboard Air India flight AI2379 from Phuket to Delhi on 4 August, an occurrence that has since been formally classified as a serious incident and handed to India's Aircraft Accident Investigation Bureau.

The aircraft lost altitude in cruise over Odisha. Injury counts reported in Indian media have varied: several outlets put the total at 17 people, comprising 13 passengers and four cabin crew; others have reported a higher figure. Because the AAIB has not published a preliminary report, the authoritative injury tally, the sequence of events and the causal chain all remain open. Nothing in this article should be read as a finding on cause.

What is on the record is that an initial technical assessment cited in Indian business media pointed to a loss of hydraulic system pressure, with flight control authority affected for a matter of seconds. Separately, Reuters reported on 11 August that the captain's confirmatory drug test returned positive for marijuana. Both crew members were taken off the roster by the DGCA pending the investigation.

Those two threads — a technical event and a positive confirmatory test — are, for now, separate facts about the same flight. Under ICAO Annex 13 conventions, the purpose of the safety investigation is prevention rather than the apportioning of blame, and investigators have not stated that the two are connected. Any regulatory conclusion drawn before the AAIB reports is a policy judgement about system-level risk, not a finding about this crew.

That distinction matters to how the proposed rule should be read. The DGCA is not responding to an established causal link; it is responding to the discovery that the existing 10 per cent sampling regime did not surface a case until an occurrence forced testing.

From 10 per cent to 25 per cent

Under the current framework, Indian operators must subject at least 10 per cent of applicable personnel to random urine screening for psychoactive substances each year. Crew are also tested after certain occurrences and on a for-cause basis.

The reported change lifts the random floor above 25 per cent. In practice, that is the difference between a pilot facing roughly a one-in-ten annual chance of selection and something closer to one in four — a shift that changes the deterrent arithmetic considerably, because the probability of going undetected across several years falls sharply as the per-year sampling rate rises.

The operational load is not trivial. India's scheduled carriers between them employ several thousand pilots and a considerably larger number of cabin crew, and a random programme has to be genuinely random — selection cannot cluster around convenient bases or off-peak rosters without undermining the statistical logic. Collection facilities, chain-of-custody handling, laboratory capacity and the roster disruption caused by pulling crew for observed collection all scale with the sampling rate.

Air India has already moved ahead of any rule change. Business Standard reported that the airline made psychoactive-substance testing mandatory for its pilots from 13 August, with several hundred pilots screened in the first phase.

What the pilots' body is asking for

The Federation of Indian Pilots (FIP) has not opposed the increase. Its submission to the DGCA, reported on 18 August, goes further in one respect and pushes back in another.

The federation has asked for random testing to be raised to 25 per cent — broadly in line with what the regulator is now said to be contemplating — and for oral-fluid, or saliva, screening to be introduced alongside the existing urine-based method.

The technical case for adding saliva is straightforward. Urine testing detects metabolites that can persist long after any impairing effect has passed; cannabis metabolites in particular can remain detectable for days or weeks in a regular user. Oral-fluid testing has a much shorter detection window, which makes it a poorer tool for establishing a pattern of use but a better one for indicating recent consumption. A regime that uses only urine can flag a pilot who was not impaired on duty; a regime that uses only saliva can miss habitual use. Running both addresses different questions.

The FIP has simultaneously pressed for stricter procedural safeguards around collection, custody and the handling of results — the counterweight pilots typically seek when testing intensity rises, given that a positive result ends a career pending appeal. It has also raised the handling of results confidentiality; Air India has faced questions over what was disclosed, and when, in the AI2379 case.

The regulatory backdrop

The proposal lands in a period of unusually visible DGCA enforcement activity. Indian media have reported more than 350 enforcement notices issued to domestic carriers between April 2024 and May 2026, and the regulator announced comprehensive special audits across the sector earlier this year, framed as a 360-degree review intended to identify systemic weaknesses rather than individual lapses.

Read against that backdrop, the testing change looks less like a one-off reaction and more like a piece of a broader posture: sample more, audit more, and treat the absence of detected problems as an open question rather than an assurance.

Internationally, India would move to the stricter end of the range. The United States operates a random testing rate for safety-sensitive aviation employees that has historically sat at 25 per cent for drugs, adjusted by the FAA according to observed positive rates — the same order of magnitude India is now reported to be moving toward. Many other authorities rely more heavily on for-cause and post-occurrence testing, backed by peer-reporting and confidential health programmes, than on high-volume random sampling.

That points to the substantive debate the rule will provoke. Random testing is a detection and deterrence instrument. It works alongside, and sometimes against, the other half of the aeromedical toolkit: confidential self-declaration and peer support schemes that depend on crew believing they can disclose a problem without immediately ending their livelihood. Push detection hard enough without a credible route back, and disclosure rates fall. The FIP's insistence on procedural safeguards is, in part, an argument about keeping that route open.

What happens next

No amendment has been published. The reported figure of "more than 25 per cent" has not been pinned to a specific number, and the crucial implementation questions — whether cabin crew are included on the same basis as pilots, whether saliva testing is adopted, what the collection and appeal procedures look like, and what lead time operators get — are unresolved.

The AAIB investigation into AI2379 is separate and ongoing. Under Annex 13 practice, a preliminary report would normally be expected within 30 days of the occurrence, with the final report to follow; any statement about what happened on 4 August properly waits for that document.

For passengers, nothing changes immediately. For India's several thousand pilots and their cabin colleagues, the odds of being called for a cup — and possibly a swab — are about to shorten considerably.
