Editorial on the Air India AI 2379 reclassification argues crew testing over emphasises alcohol breathalysers relative to psychoactive substances under the Civil Aviation Requirements

Why in the News

The 4 August 2026 flight from Phuket to Delhi, carrying 137 passengers and eight crew, has been reclassified from an event of turbulence to a serious incident after technical faults and a significant altitude deviation injured more than 20 people on board. The post flight screening of the pilot in command for psychoactive substances has exposed a crew fitness regime built around alcohol breathalysers rather than drug testing.

What are the Civil Aviation Requirements (CAR)?

1. About: The Civil Aviation Requirements are the binding regulatory instructions issued by the Directorate General of Civil Aviation (DGCA) under the aircraft rules, organised into numbered Sections and Series that operators must comply with to hold and retain approvals.
2. The relevant provision: Crew testing for psychoactive substances falls under CAR Section 5, Air Safety, Series F, Part V, which also applies to Air Traffic Controllers.
3. Its testing design: The requirement leans towards random and post flight or post shift testing with graded disciplinary action for a confirmed positive result.

What is a serious incident in civil aviation?

1. About: A serious incident is an occurrence involving circumstances indicating that an accident nearly occurred, a category distinct from an accident by the absence of the resulting damage or injury threshold.
2. Why the label matters: Reclassification from turbulence to a serious incident makes a formal independent investigation mandatory rather than leaving the occurrence to airline level reporting.

What is the Aircraft Accident Investigation Bureau?

1. About: The Aircraft Accident Investigation Bureau (AAIB) is the body under the Ministry of Civil Aviation that investigates aircraft accidents and serious incidents, kept institutionally separate from the DGCA so the regulator does not investigate outcomes of its own oversight.
2. International participation: Investigations draw in the safety authority of the State of design and manufacture, which is why France’s Bureau d’Enquetes et d’Analyses (BEA) and technical representatives of the manufacturer have joined this probe.

What are psychoactive substances in the aviation context?

1. About: Psychoactive substances are drugs that act on the central nervous system and alter perception, mood or cognition, covering narcotics, sedatives, hypnotics, cannabis, stimulants and certain over the counter medications.
2. Why they matter on the flight deck: They impair judgement, reaction time, coordination and decision making, which are the four skills a flight crew relies on during an abnormal event.

What actually happened on the flight?

1. Two parallel tracks: The occurrence now has a technical track and a crew fitness track, and the second has drawn the greater attention.
2. The technical anomalies: The Airbus A320N briefly carried fault warnings across the hydraulic systems, elevator flight control faults, autopilot disconnection, emergency exit door indications and an engine anti ice warning.
3. The consequence: Inflight technical issues and a significant deviation in aircraft altitude caused injuries to more than 20 passengers and crew.
4. The manufacturer’s data: Airbus’s initial data is said to support the evidence of technical errors.
5. The airline’s response: The operator has begun immediate and mandatory screening of its flight deck crew for any substances or unprescribed medications.

Why does the current crew screening regime under detect impairment?

1. The testing asymmetry: Pre flight and post flight breathalyser checks for alcohol are routine and near universal, while testing for psychoactive substances is comparatively sparse.
2. Detection after the event, not before: The pilot in command’s result surfaced through post flight screening following an incident, which means the system caught the risk only after passengers were injured.
3. Random testing as the primary tool: A regime built on random and post shift sampling cannot guarantee that an impaired crew member is stopped before a specific flight departs.
4. Voluntary action filling a regulatory gap: Mandatory screening began because a single airline was prodded into it, not because the requirement applies uniformly across operators.
5. Rising exposure: Expanding operations, crew citing stress related issues, and wider availability of substances for medicinal or recreational use together enlarge the risk the regime is not sized for.

What does the regulator’s own evidence base already establish?

1. The medical circular: DGCA Medical Circular No. 02 of 2021 on over the counter drugs and self medication flags impairment of pilot cognitive and psychomotor skills.
2. The Indian precedents it draws on: The circular draws on the Mangaluru (2010) and Kozhikode (2020) fatal air accidents. The 2010 crash of an Air India Express flight at Mangaluru killed 158 people after a runway overrun on a tabletop runway, and the 2020 accident at Kozhikode killed 21 in a similar runway excursion.
3. International documentation: Documented cases from Western jurisdictions show that even small levels of impairment affect crew judgement, reaction time, coordination and decision making.
4. The implication: The evidence linking impairment to fatal outcomes already exists in the regulator’s own material, so the gap is enforcement design rather than knowledge.

Challenges to crew fitness regulation in India

1. Self reporting of medication and illness: Disclosure of prescribed and over the counter drug use depends on the crew member volunteering it, with a licence at stake. e.g. DGCA Medical Circular No. 02 of 2021 exists precisely because self medication goes undeclared.
2. Punitive rather than rehabilitative framing: Graded disciplinary action deters disclosure of a substance or mental health problem instead of surfacing it. e.g. pilot bodies have repeatedly objected that a positive breathalyser result triggers suspension without a treatment pathway.
3. Fatigue rules lagging operations: Flight duty time limitations are revised slowly while network expansion increases night operations. e.g. revised flight duty time limitation norms for night duty and weekly rest were phased in only after sustained pilot representations.
4. Testing infrastructure at smaller stations: Drug testing requires sample collection, chain of custody and accredited laboratories that are absent outside metro airports. e.g. a post flight test at a small regional airport under the regional connectivity network has no on site collection facility.
5. Thin regulatory staffing against a growing fleet: Oversight capacity has not scaled with aircraft and operator numbers. e.g. the International Civil Aviation Organization’s safety oversight audits have repeatedly flagged vacancies in the technical cadre of the Indian regulator.
6. Air Traffic Controllers inside the same requirement, outside the same attention: The requirement covers controllers, and the screening debate stays confined to flight deck crew. e.g. controller fatigue and staffing shortfalls at busy terminal control areas rarely feature in post incident action.

Conclusion

The reclassification converts an event described as turbulence into a serious incident with a formal investigation into both airframe faults and crew fitness. The crew screening system detected a psychoactive substance result only after an incident had already injured more than 20 people, because the regime is built around alcohol breathalysers and random sampling. The next step is the Aircraft Accident Investigation Bureau’s findings with the French authority and the manufacturer, and the immediate question for the regulator is whether mandatory psychoactive substance screening becomes a uniform requirement across operators rather than one airline’s response. Safety here depended on the aircraft recovering, and that is an outcome, not a control.

Civil Aviation Safety Regulation in India

1. About: Civil aviation safety in India is regulated by the Directorate General of Civil Aviation under the Ministry of Civil Aviation, which certifies aircraft, licenses crew, approves operators and issues the Civil Aviation Requirements.
2. Investigation function: Accidents and serious incidents are investigated by the Aircraft Accident Investigation Bureau, kept separate from the regulator, in line with the International Civil Aviation Organization’s Annex 13 principle that investigation is for prevention and not for apportioning blame.
3. Economic regulation: The Airports Economic Regulatory Authority sets tariffs for major airports, and the Airports Authority of India provides air navigation services and manages airports.
4. Scale: India is among the largest domestic aviation markets in the world, with fleet and passenger volumes growing faster than regulatory staffing.
5. International anchor: India is a founding member of the International Civil Aviation Organization, and Indian standards derive from the Chicago Convention, 1944 and its Annexes.

Challenges in India’s Civil Aviation Sector

1. Regulator capacity against fleet growth: Technical posts remain vacant while aircraft numbers, operators and flights expand. e.g. International Civil Aviation Organization safety oversight audits have flagged shortfalls in trained flight operations inspectors.
2. Airport and airspace congestion: Slot and runway capacity at metro airports lags demand, which compresses turnaround times and crew rest. e.g. Delhi and Mumbai airports operating near saturation during peak banks.
3. Airline financial fragility: Thin margins push cost cutting into maintenance, training and rostering. e.g. the collapse of Jet Airways in 2019 and of Go First in 2023 left aircraft grounded and crew displaced.
4. Skilled manpower shortage: Pilots, aircraft maintenance engineers and air traffic controllers are trained in numbers below the sector’s expansion rate. e.g. Indian carriers holding large order books have had to lease aircraft with foreign crew.
5. Maintenance dependence on foreign facilities: A limited domestic maintenance base sends heavy checks abroad, raising cost and turnaround time. e.g. a large share of Indian airline heavy maintenance has historically been done in Sri Lanka, Singapore and West Asia.
6. Bird strike and wildlife hazard at airports: Waste dumps and abattoirs near airport perimeters draw birds into approach paths. e.g. recurring bird strike reports at airports adjoining municipal landfill sites.
7. Weather and terrain risk at critical airfields: Tabletop runways and monsoon operations narrow the safety margin. e.g. the Kozhikode runway excursion in heavy rain in 2020.

Way Forward

1. Make psychoactive substance screening mandatory and uniform: Extend routine pre flight and post flight screening for substances beyond alcohol across every operator rather than leaving it to voluntary action.
2. Build a non punitive disclosure pathway: Create a confidential reporting and rehabilitation route for crew with a substance or mental health problem, with return to duty after medical clearance.
3. Expand testing infrastructure: Provide accredited sample collection and chain of custody facilities at regional airports, not only at metro stations.
4. Strengthen fatigue risk management: Enforce revised flight duty time limitations with audited rostering data instead of self declared compliance.
5. Staff the regulator: Fill technical inspector vacancies and give the regulator recruitment autonomy so oversight scales with fleet growth.
6. Extend the same rigour to Air Traffic Controllers: Apply the testing and fatigue standards uniformly to controllers, who are already covered by the same requirement.
7. Publish investigation findings promptly: Release Aircraft Accident Investigation Bureau reports with safety recommendations and track their implementation publicly.
