Jet2 - Rapid descent due to cabin pressure loss 30 mins in

Can't find many details of this out and about on the Interwebs, but looks like a loss of pressure and subsequent rapid descent upset a few pax:

Terrifying moment plane 'fell from the sky' during flight to Leeds Bradford Airport as passenger texted his goodbyes - Yorkshire Evening Post

Bet that woke up the people settling down for a nap!
Anyone have any more details? Flight was Ibiza to Leeds.

Apparently it was LS264 on July 16.

From the article linked above:

An airline passenger flying to Leeds Bradford Airport sent his wife what he thought was a final text as the plane he was on PLUMMETED towards the sea in a 40-50 degree nosedive.

"They had the snack trolleys out and the seat belt lights were off, but the staff ran flat out to put them back. Then the emergency masks dropped down and the plane started diving down in at least a 40-50 degrees dive."
If they really got 40 to 50 degrees nose down with the seat belt signs off I would expect some pax acrobatics.

Looks like they took some turns in holding to sort things out and burn off fuel before landing at BCN:

I'd guess human perception probably at least doubles perceived angles (45° nose-down probably looks "straight down" to some, especially if it is a threatening angle).

I know that in even a tame wingover, the moment the windscreen shows "nothing but ground", it feels like a 60° dive, even though I know I'm well less than the 30° pitch limit for non-aerobatic maneuvers.

He said: "We were sat on the runway in Barcelona for what seemed like forever. "I suppose it must have only been 40 minutes, but with no air conditioning we were all completely soaked in sweat."


Curious. This would suggest the APU was U/S. I wonder if that was an ingredient into the scenario. Surely the local BCN rules about APU usage would have been binned by the crew.

Not necessarily, all it implies is that the air feed to the cabin was in some way compromised, which would be commensurate with a depressurisation.

Slightly OT , but I'm glad to see that shoddy journalism on local newspapers isn't restricted to our local rags here in the North East. When was the Mediterranean upgraded to an ocean?

Whilst a very rare occurrence, loss of cabin pressure does happen. Therefore emergency descents are practised regularly in the simulator. In this event tne pilots were busy carrying out an emergency procedure, when the aircraft is at a safe altitude the pilots will again be busy analysing what caused the loss of pressure etc. The old aviation adage " aviate, navigate, communicate " is important. Pax safety is paramount, the whole crew apparantly did a good job. No one was hurt, so whats all the fuss about? Passengers are so blase; who listens to the CC " in the event of the sudden loss if cabin pressure etc" and one bright spark allegedly sent a text, sorry did he not hear the "all electronic devices must be switced off"

Guys, isn't it time Jet2 upgrade all of their aircraft?

This particular aircraft, a 734, was 30.9 years old!

Jet2 have had quite a few incidents lately. If they keep this up, the Swiss cheese will eventually align! Time for an upgrade me thinks.

Yes, and no brand new aircraft has ever had a decompression...

Come on Chesty, you know the truth here. Jet2 have such an ageing fleet they're nearly as old as I am. Now I know that old aircraft does not necessarily mean crashes left, right and centre (it all comes down to maintenance these days) but how good is the maintenance behind Jet2?

Have a read of the many recent incidents for the answer.

Yes, two-thirds of their 60-strong 737 fleet are -800s, the most recent delivered about 3 months ago, with about another 20 to come.

It can't be done overnight, the process started last year and continues for another year or so yet. It is happening, but you can't replace 60(ish) aeroplanes overnight.

but how good is the maintenance behind Jet2?
It is excellent (haven't flown an aeroplane with a yellow sticker for months).

No matter which airline or how old the aeroplane, things go wrong sometimes, it's how they are then dealt with that is important. This incident proved that, a well flown manoeuvre and diversion with a replacement aeroplane dispatched at short notice to collect the passengers and continue their journey.

My limited knowledge of Jet2 is that they only dispatch airworthy aircraft. I'll agree old aircraft have more faults, that's why they are cheaper to buy/lease. It also means you have to have more engineering, spares and back-up aircraft otherwise you'll be forever forking out compo and doing battle with the unwashed on social media. Eventually though you will have to say good bye to some of the oldest airframes and replace them with something newer. A bit like what they are doing now.

Incident: British Airways B789 near Brussels on Apr 29th 2017, loss of cabin pressure

Looks like BA need to trade in their 789's. Pesky old aircraft.

As for Jet2 maintenance. Have a word with the CAA, and I think you will find that it is held in very high regard. Indeed it has been very heavily invested in recently and like JFP, I haven't flown an aircraft with an ADD for months.
