VP-BUM (msn 1361) was operated through April 2019 by Jet Airways (JAI, Mumbai Int'l) and has remained in storage since the collapse of the Indian airline. Nordwind Airlines is currently using the 8.6-year-old widebody, owned by CDB Aviation, to connect various Russian cities (Kazan Int'l, Moscow Sheremetyevo, and Samara Kurumoch) with Antalya in Turkey.
The A330-300 is the second new type in Nordwind Airlines' fleet in recent weks, after the induction of the airline's first A321-200N in early June 2021. The leisure specialist had originally hoped to induct the A330-300 in May 2020, but border closures caused by the COVID-19 pandemic delayed the plan. Nordwind Airlines is expecting a second A330-300 shortly.
Shenzhen Airlines Airbus A330-300 Suffers Loss Of Cabin Pressure
A Shenzhen Airlines Airbus A330-300 today suffered a sudden loss of cabin pressure at 9,100 meters (FL300). The aircraft rapidly descended to a safe altitude, dropping some 9,000 m in under two minutes. The plane returned to its origin airport at Shenzhen, landing safely less than two hours later.

An emergency descent
The A330 was performing a routine flight from Shenzhen to Xian under the flight number ZH-9209. Almost 25 minutes into the flight, after climbing out of Shenzhen’s Bao’an International Airport, the crew noted an abnormal pressurization of the cabin, and proceeded to descend to a safe altitude.
The plane is reported to have ‘plunged’ more than 9,000 m in under two minutes, likely a frightening experience for the passengers. At this point, the crew sent out an emergency 7700 squawk.
Five minutes later, it seems that the pilots tried to climb again. However, the ascent was aborted at around 6,000 meters (FL197). The aircraft then turned back and landed safely back in Shenzhen about 100 minutes after departure.
As of now, there is not a huge amount of available information on the incident. It is known that all the passengers and crew onboard the aircraft are safe and no one was injured seriously. An alternate Airbus A330-300 with registration B-1036 completed the flight with a delay of about 4.5 hours. The involved aircraft is still on the ground about 10 hours after landing.
Possible reasons
Although the loss of cabin pressure is not a frequent phenomenon, there have been many such instances in the past. Frequent fliers will relate to pre-departure announcements, which advise passengers to use the oxygen masks if a loss in pressure occurs. Though it might sound scary, having a knowledge of such a situation can prove to be very vital.
Aircraft cabins are pressurized using cooled, and filtered air bled from the engines, keeping the air pressure inside the cabin at the equivalent of an altitude of around 8000 feet. This is done in order to create a safe and comfortable environment for passengers and crew flying at high altitudes. Significantly lowering cabin pressure can have fatal consequences on passengers onboard.
