Mumbai: Five Jet Airways passengers, who suffered nose and ear bleeding Thursday after the crew failed to turn on a switch that controls cabin air pressure, were diagnosed with "mild conductive deafness" and later discharged from hospital, officials said.
Oxygen masks dropped down during the emergency incident on board Flight 9W697 from Mumbai to Jaipur, before the plane landed safely.
The incident happened on early Thursday morning when Jet Airways Flight 9W 697 took off from Mumbai for a flight to Jaipur.
"Jet Airways is extending full cooperation to the DGCA for the ongoing investigation and regrets the inconvenience caused", the spokesperson said. "As a result, oxygen masks got deployed", an official at Directorate General of Civil Aviation (DGCA) said. A year later, investigators concluded that omissions in controlling cabin pressure was a key reason for the crash.
"I saw many people having nose bleeds..."
Captain Rangnathan, who is a former instructor pilot of Boeing 737, said "If the bleed switches are turned back on, the cabin pressure normalises in about five minutes".

Cannabidiol, or CBD, does not produce the high commonly associated with marijuana. It has been used to treat epilepsy and other maladies.
During the climb, the crew of the B737 aircraft forgot to select the bleed switch, which allows high pressure bleed air from the engine to be used for cabin pressurization. It went on to add that the plane landed normally as guests "deplaned safely" and taken to terminal.
Those affected were given medical attention while alternative flights were arranged, Jet Airways said.
Oxygen masks dropped from the cabin's ceiling. "They have suffered "barotrauma" of ears due to change in air pressure".
The civil aviation ministry has taken note of the situation and has requested the aviation regulator DGCA to file its report immediately on the issue.
Oxygen masks were deployed on a Jet Airways flight, traveling from Mumbai to Jaipur, India, Sept. 20, 2018.
Flightradar24's flight map showed the plane reached an altitude of 11,000 feet before turning back to the airport.
A doctor said that the five travellers are suffering from temporary mild deafness and they're now recuperating in a Mumbai hospital. Just a few days ago, an Air India pilot narrated one of his worst nightmare over a brief radio message.
