A maintenance report printed out in the cockpit of Air India aircraft from Phuket to Delhi, which experienced a sudden loss of altitude of 300 feet during its cruise phase injuring several passengers, indicates that the airline had suffered a series of hydraulic faults. The report was published at 11:14 am on August 4, after the flight landed in Delhi.
Two hours later, at 1:14 pm, Air India issued a statement where they attributed the crisis onboard the aircraft to a ''brief in-flight turbulence-related event during cruise, resulting in a momentary change in altitude.''
