Air India B787 Dubai-Cochin flight diverted to Mumbai due to cabin pressurisation loss

An Air India Boeing 787 aircraft with flight number AI 934 from Dubai to Cochin had to be diverted to Mumbai due to cabin pressurisation loss, adding to the growing number of flights that had to be diverted due to technical snags.

The aircraft was cruising at 37,000 feet when the issue occurred and saw oxygen masks being deployed with some of the passengers suffering nosebleeds. The pilots immediately contacted the integrated operations control centre (IOCC) of the airline as well as the air traffic controller.

Following the depressurisation, the pilots descended the aircraft to 10,000 feet. The plane was allowed to divert to the nearest airport, which in this case was the one in Mumbai and it landed safely.

“The captain reported the pressurisation loss to the Air India Integrated Operations Control Centre, and diverted the flight to Mumbai,” a DGCA official said. There were 247 passengers and 11 crew members on board.

The flight had landed safely at Mumbai’s Chhatrapati Shivaji Maharaj international airport. As per the information by the Directorate General of Civil Aviation (DGCA), senior officers of O/o DAS WR are assigned the task to carry out a preliminary investigation.

Jet aircraft fly at high altitudes with a pressurized fuselage that maintains pressure and temperature levels inside the aircraft at levels physiologically fit for humans.

The aircraft was cruising at 37,000 feet when the issue occurred and saw oxygen masks being deployed with some of the passengers suffering nosebleeds.

While most jets have cabin air pressure equivalent to that experienced at an altitude of 8000 ft, the Dreamliner with its composite fuselage can maintain a lower cabin pressure of about 6,000 ft.

The alternate aircraft arranged for passengers of the Dubai-Kochi Air India flight that got diverted to Mumbai a day ago due to a loss of cabin pressure landed at the Cochin International Airport here early on Friday, July 22 morning.

An alternate aircraft AI 1681 BOM-COK from Mumbai landed at 0433 hours today with 180 passengers. The rest of the passengers will arrive on an Air India flight at 0730 hrs.

The Directorate General of Civil Aviation (DGCA) has ordered a probe into the incident that took place on July 21 when an Air India flight from Dubai to Kochi was diverted to Mumbai due to a loss of cabin pressure after which an alternate aircraft was arranged to carry passengers from Mumbai to Kochi.

A senior DGCA official informed that the captain of Air India Boeing Fleet Aircraft of Flight No. AI- 934 from Dubai – Cochin, reported to IOCC (Integrated Operations Control Centre) regarding pressurization loss in the aircraft. The flight was diverted to Mumbai and it landed safely.

Two senior officers of DAS WR are assigned the task to carry out a preliminary investigation. He added that an inquiry has been ordered.

In an incident of technical malfunction, the windshield of a Go First flight between Delhi and Guwahati cracked mid-air due to bad weather on Wednesday, July 20. The aircraft was diverted to Jaipur and landed safely.

Earlier this month, DGCA said that 30 such incidents take place daily, but these occurrences hardly have any safety implications. “On average, about 30 incidents do take place, including go-around, missed approaches, diversion, medical emergencies, weather, technical and bird hits,” the top DGCA told ANI.

“Most of them have no safety implications. On the contrary, they are a sine qua non of a robust safety management system,” he added.

In similar incidents, another two Go First flights were diverted due to engine snags. The DGCA has said that the matter is being investigated and the aircraft are being grounded. The DGCA added that the flights will take off once they get clearance from the authority.

Earlier on July 17, an Air India Express aircraft while operating from Calicut to Dubai was diverted to Muscat after a burning smell was observed from one of the vents in the forward galley of the flight.

Meanwhile, after frequent engineering-related glitches were reported in several airlines, the DGCA conducted several spot checks and advised that all aircraft at base and transit stations shall be released by certifying staff holding a licence with appropriate authorization by their organization.

The spot checks carried out by DGCA teams have indicated the improper identification of the cause of a reported defect, increasing trend of minimum equipment list (MEL) releases and non-availability of required certifying staff to cater to multiple scheduled arrivals/ departures in a short interval.
