Narrative:
Jet Airways flight 9W697 returned to land at Mumbai Airport due to a cabin pressurization issue.
The aircraft, a Boeing 737-800, departed Mumbai at 00:42 UTC on a service to Jaipur. Five minutes into the climb, after passing 10,000 feet, the oxygen masks dropped in the passenger cabin. The flight crew stopped the climb and descended back to 10,000 feet. It was decided to return to Mumbai, where a safe landing was made at 01:24 UTC.

Some 21 passengers had reported nose bleeding, few had ear bleeding and some were complaining of a headache. Airport sources added that about 10 passengers have been taken to hospital for further check-up.

PROBABLE CAUSE
Bleed switches left at OFF position by the AME after the maintenance task, which remained at OFF position during the flight also because of Flight Crew missing note of its position during pre-flight scan, not putting it ‘’ON’’ during “Before Take Off” & “After Take Off” checks resulted in the incident of cabin not getting pressurized.
Not handling the situation as per the procedure caused discomfort in ears and bleeding from nose of some of the passengers.
