A Jet Airways flight this morning from Mumbai to Jaipur had to return to Mumbai due to pressurization issues with the cabin, which caused passengers to bleed out of their noses and ears.
The flight, 9W697, was operated by a Boeing 737. What caused the cabin not to be pressurized?
“During climb, crew forgot to select bleed switch due to which cabin pressurisation could not be maintained. As a result, oxygen masks got deployed,” said the official.
The pilots have been suspended pending an investigation. Out of the 166 passengers onboard, about 30 were bleeding out of their noses, and a few were bleeding out of their ears. 10 passengers were taken to the hospital, while the remaining passengers were checked out by the doctors at the airport.
The Aircraft Accident Investigation Bureau has said that based on preliminary information it appears this was a case of negligence, given that part of the pre-flight check is making sure the cabin is pressurized correctly.
When I read about the pressurization issues, the crash of Helios 522 was the first thing that came to mind. Of course that was much worse, but this similarly occurred due to not having cabin pressurization set correctly.
