India's Directorate General of Civil Aviation (DGCA) has launched a detailed investigation after an Air India flight from Phuket to Delhi experienced a brief altitude variation during flight.
The Airbus A320 carrying 137 passengers, including three infants, and eight crew members later stabilized and landed safely at Delhi's Indira Gandhi International Airport, according to a statement issued by the Civil Aviation Ministry on Tuesday.
"The aircraft has been moved to the hangar and the Flight Data Recorder and Cockpit Voice Recorder have been secured for detailed examination," the ministry said.
Eight passengers and four cabin crew members were hospitalized for evaluation and treatment, while the remaining passengers received assistance.
