Why Two Separate Agencies, Not One, Are Handling the Air India Turbulence Case

Why the Regulator Grounded the Pilots, But a Different Body Is Investigating Them

Here's what's actually happening institutionally in the Air India turbulence case, stripped of the drug-test headline: two separate government bodies are handling this incident and they're deliberately not the same one.

The Two-Body Design, Explained Simply The Directorate General of Civil Aviation (DGCA) is

India's aviation regulator - the body that licenses pilots, sets safety rules and can take immediate administrative action like off-rostering a crew member. When AI2379 dropped 300 feet and injured 17 people, DGCA acted fast: both pilots were taken off roster pending investigation, using its regulatory authority.

But DGCA is not the one investigating what actually went wrong. That job belongs to the Aircraft Accident Investigation Bureau (AAIB), a separate body under the Ministry of Civil Aviation, set up in 2012 specifically so that accident investigation wouldn't be conducted by the same agency that writes and enforces the safety rules.

Think of it like this: DGCA is the traffic police officer who can pull a driver off the road immediately; AAIB is the accident investigator who determines, independently, what actually caused the crash - and the second job only stays credible if it isn't done by the officer who wrote the traffic rules in the first place.

Where the Line Could Blur

The trigger for AAIB's involvement is classification: DGCA initially treated this as a routine occurrence, but once it was classified as a "Serious Incident," the investigation formally shifted to AAIB. That classification threshold matters more than it looks - it's the switch that moves an event from routine regulatory handling into independent scrutiny and who decides the classification and how quickly, determines how fast an independent probe actually starts.

The pilot's pending confirmatory drug test sits right at this institutional seam. DGCA already acted on the initial screening result by grounding the crew - a regulatory, precautionary step. But whether that screening result becomes a finding of fault is something only AAIB's investigation, alongside the flight data recorder and cockpit voice recorder now secured, can determine.

If DGCA were also running the investigation, its own prior grounding decision could look like it was pre-judging AAIB's conclusion before the evidence was even examined. That's the actual mechanism worth understanding here: regulatory action and investigative independence are kept in separate hands specifically so a body with the power to punish doesn't also control the finding of what happened - a structure aligned with ICAO Annex 13 guidelines that most serious aviation systems worldwide now follow.
