A new controversy has emerged around an Air India flight from Phuket to Delhi after reports claimed that the captain underwent a post-flight dope test that allegedly indicated the presence of psychoactive substances.
The development comes days after the flight encountered severe turbulence during its journey, resulting in injuries to passengers and crew members. The reported test result has now prompted scrutiny from aviation authorities and raised questions about the fitness of the flight crew.
What happened on the Phuket-Delhi flight?
Air India flight AI2379, operating from Phuket to Delhi on August 4, encountered a sudden and severe turbulence event during cruise.
The aircraft reportedly experienced a brief but significant change in altitude. Several people onboard were injured and some passengers and crew members were taken for medical evaluation after the aircraft landed safely in Delhi. Air India had earlier described the incident as turbulence-related.
The turbulence itself has not been officially linked to any alleged substance use by the pilot.
Did the pilot test positive?
Reports published on August 9 claimed that the captain underwent a mandatory post-flight test for psychoactive substances and that the result was reportedly positive.
However, the reported result has not been officially confirmed by Air India.
According to Air India’s response reported by multiple media outlets, the airline says it conducts mandatory testing of crew members but has not received the alleged test result. The airline is therefore awaiting the official report before drawing any conclusions.
This distinction is important because media reports currently describe the result as an allegation or report from sources rather than an officially confirmed finding.
Air India’s response
Air India has said that it regularly conducts tests for drugs among its crew members and that it is awaiting the official outcome of the test reportedly conducted after the Phuket-Delhi flight.
The airline has also indicated that the matter is being dealt with through the appropriate regulatory and safety procedures.
Until the official report is communicated, it would be premature to conclude that the pilot operated the aircraft while under the influence of a prohibited substance.
What are psychoactive-substance tests?
India’s aviation regulations provide for testing flight crew and air traffic controllers for psychoactive substances. The testing framework covers substances that can potentially impair alertness, judgment, coordination or other abilities essential for aviation safety.
Such testing is separate from the breathalyser examinations used to detect alcohol consumption.
A positive screening result can also require further verification, depending on the testing procedure and applicable regulations. Therefore, a reported positive result should not automatically be treated as a final determination of impairment without the official documentation and regulatory process.
DGCA looking into the matter
The reported test result has added another layer to the investigation surrounding the Phuket-Delhi turbulence incident.
The Directorate General of Civil Aviation (DGCA) is examining the incident, while the reported dope-test issue could be assessed separately under aviation safety regulations. Reports say the concerned crew members have been removed from flying duties pending further investigation.
The investigation is expected to establish what happened during the turbulence event, whether any procedural violations occurred and whether the reported test result is genuine and actionable.
Was the turbulence caused by the pilot?
There is currently no evidence establishing that the reported psychoactive-substance test had anything to do with the turbulence.
Severe turbulence can occur suddenly, including in situations where pilots receive little or no advance warning. The turbulence event and the reported drug-test result should therefore be treated as two separate issues unless investigators establish a connection.
The aircraft landed safely in Delhi, although several people onboard required medical attention following the incident.
What happens next?
The key development now will be the official test report and the findings of the aviation regulator.
If the test is confirmed positive, authorities would have to determine the substance involved, whether the result was confirmed through the prescribed testing process, whether the pilot was medically or operationally impaired and what regulatory action is warranted.
If the reported result is not confirmed, the current allegations could ultimately prove unfounded.
For now, the safest conclusion is that a positive dope-test result has been reported by media sources, but Air India says it has not received the official result. The airline and aviation authorities will need to complete the investigation before the allegation can be treated as an established fact.
Bottom Line
The Phuket-Delhi flight incident has raised legitimate aviation-safety questions, but the alleged positive test should not yet be presented as confirmed.
What is known: the flight encountered severe turbulence, people were injured, and a post-flight test was reportedly conducted.
What remains unconfirmed: whether the captain actually tested positive for psychoactive substances.
Air India says it is awaiting the official report. The final findings from the airline and DGCA will determine what actually happened and whether any regulatory action is required.
