More than 30 Indian passengers, some bleeding from their noses and ears, have received treatment after pilots "forgot" to turn on a switch regulating cabin pressure, officials said. The crew of flight 9W 697 failed to flip the "bleed switch," because of which cabin pressure couldn't be maintained, causing oxygen masks to deploy when the aircraft was gaining altitude, the nation's aviation regulator said. Pictures on social media showed oxygen masks dropping down just a few minutes after 9W 697 took off, but some passengers said there was no air flowing through them. About 30 of the 166 flyers aboard the Boeing 737 aircraft from Mumbai to Jaipur suffered bleeding in their noses, and some in their ears, and forced the plane to return, according to a statement from the Directorate General of Civil Aviation in New Delhi. The Directorate General of Civil Aviation (DGCA) said: “The crew has been taken off duty and Aircraft Accident Investigation Bureau (AAIB) has started an investigation.”

Civil Aviation Minister Suresh Prabhu directed officials concerned to prepare a comprehensive safety audit plan, which involves assessment of safety parameters of all scheduled airlines, aerodromes, flying training schools and MROs immediately, an official statement said and sought a report within 30 days. Here’s the copy of the complaint:

Meanwhile, the Ministry of Civil Aviation has ordered an inquiry into the incident and the airline has de-rostered the pilots and an aircraft maintenance engineer.
