Ryanair Loss of Pressurisation 25th Aug

BBC NEWS | UK | Forced landing for Ryanair flight

A Ryanair flight carrying British holidaymakers has been forced to make an unscheduled landing due to a loss of cabin pressure, the company has said.
Flight FR9336 from Bristol to Barcelona Girona Airport was hit by a "depressurisation incident" on Monday night, Ryanair confirmed.
Looks like it was all handled properly, Ryanair even apparently paying for onward journey by coach for those who didn't want to fly the rest of the way.

Ryanair incident - crazy week for the aviation industry

It sounds like all involved did extremly well to keep the situation under control - very proffesional and from what little news thats filtering thru sounds like a lot of the passengers where extremly frightened by the whole incident - Oxygen masks deploying etc .

Passengers wud have been aprehensive anyway especially considering the bad week that the aviation industry is having .

To be honest i know there is always a bit of a media frenzy when One passenger jet is involved in a fatal accident never mind 3 in a week !

Madrid , kyzakerstan , Guatemala and thats not counting the incidents involving the mid air collision coventry and other light aircrafts .

Tomorrow people are going to see the Ryanair depressurisation & and theAir Dolomiti fire all over the news .

Its a strange one ...what would cause a depressurisation like that anyway ?

Most of Ryanairs fleet are boeing 737-800's and are practically brand spanking new

Not sure of the specific cause but imho airlines and other maintenance facility's must be feeling the pinch in today's financial climate and, dare I say it, may be looking at cost cutting in certain areas such as maintenance?? Its a very sensitive subject but I for one work for a company which has recently extended the periodicity of its servicing cycles on its aircraft. The incidents over the past few weeks may just be a coincidence but it raises a few questions in some minds, including my own.

Hope I'm mistaken

You can't just 'raise the periodicity' of maintenance checks.

Maintenance periods are set by manufacturers and approved by the appropriate regulatory authority. Any change in periodicity has to come from the manufacturer and be approved by said authority.

Was approved by all the correct agencies. Not a EEC based outfit but still comes under the general rules of the ICAO.

In that case it is still being maintained IAW the manufacturers schedule and approved by the authorities. Your statemenet saying that the period is extended is just another piece of sensationalism!

A report I read this morning says the aircraft "plummeted"

I'm sure the dictionary will not have the words "controlled descent from XXX feet to XXX feet" next to the word plummeted!

Aren't Ryanair jets registered in Ireland?

They are - all Ryanair jets carry EI registrations.

The Today programme had a wells-spoken chap on complaining that the oxygen masks didn't seem to work and that there was no PA explaining anything until after the a/c got to 8000'.

MoL came on afterwards and did a good job of explaining what happened - could have pointed out that the procedure is standard across the industry and not 'his' safety procedures, which the interviewer was implying.

Seems like a standard 'passengers in death plunge' report - ie, everything worked fine but none of the pax knew what was going on at the time. And a planeful of frightened people, all of whom have a suspicion that their five euro fares mean that maintenance is slack, will make the news.

Possibly an argument for including a short 'in the event of' bit on the seatback safety card. I seem to remember Concorde had one, presumably because of the rather dramatic depressurisation/engine out procedure at altitude.

RYR depressurisation

I have just listened to O'Loire being rubbished on the BBC's "Today" because his crew reacted in the correct way to the emergency depressurisation. How did Ed Stourton think the Cabin Crew were going to talk to passengers when they are trained to save their own lives by grabbing the nearest [passenger] oxygen mask? There is no point in the pilots trying to communicate with the pax with their masks on as those of us who have used them know that they would not be understood.

What is obvious is that if the pax had listened to/watched the safety briefing, they might have known what to do. I travel around Europe a lot on a variety of airlines, and only one, easyJet, chastises people for not paying attention to the safety briefing. We have all seen it - the regular traveller makes his point by deliberately reading his newspaper whilst the foreigner does not know what is going on. To give them their due, Ryanair have a clear Irish voice reading the English version, which is usually followed by the briefing in the language of the destination.

This has been an incident waiting to happen for some time - on none of the safety briefings I listen to, including those from the "World's Finest" is it stressed that one must 'tug' the oxygen tube to start the chemical generators. "Pull the mask towards you" is simply not enoough.

I think that there is a case for a pre-recorded announcement to explain to the passengers what is happening. Saying that there will be a rapid descent etc.
The cabin crew would then just have to "hit the tit" and it would reduce the "we're all doomed" anxiety perhaps.

A job well done, it would appear.

It would also appear that the passenger did not act in accordance with the safety instructions by attending to his son's mask before his own.

In the real world this is bollocks!

If an oxygen mask suddenly appears in front of your face then it is for a reason.

This tugging shit is wrong!!!!

If the mask is dangling there it should be activated.

How hard is a "tug" (thinking when the aircraft is plummeting a tug is like 400lbs)

having performed an emergency descent some time ago, I must admit the passengers were all gratefull that i took time to explain the problem to the passengers as soon as we reached 10000ft.
It is really disturbing for them, not so much the descent which is quite smooth, but the heat caused by the oxygen generators of the pax oxygen masks, and the fact that the oxygen flow is quite low allthough largely sufficient.
I also told them they could breathe normaly and didn't need the masks anymore.
Nobody was hurt and nobody needed an hospital treatment... but with all the rubish we read in the papers today , I am not surprised of the number of passengers going to hospital

Limp Leek,

Putting aside your careful analysis for a moment - you are failing to consider the implications of a cabin that is only partially occupied e.g. 180 capacity, 60 pax. Having oxygen flow to every mask is jeopardising supply(not infinite), and to a lesser extent, pressure.

Regards.

I listened to the Today programme piece with Ed Stourton interviewing Pen Hadow the passenger and polar explorer and then grilling O'Leary. I don't usually whinge about the press, but it was typical of Britain today. O'Leary was grilled on the basis that Ryanair had been utterly deficient because there had been inadequate PA announcements from the flight deck until they were at 8,000 ft. He pointed out that the crew had their own masks on and were busy making an emergency descent, but this didn't really seem to cut much ice.

Sh*t happens, it was scary, nobody was hurt. People need to live with that. I am surprised at Stourton's attitude as I had thought him an excellent broadcaster. Even more surprising was the polar explorer's attitude, but there you go: the demise of British phlegm.

I, too, heard the interviews on BBC Radio 4.
For me, they raised a couple of questions:
I think MOL said that flight deck crew could not communicate with passengers when wearing oxygen masks (I was in the shower and couldn't hear very clearly). Is this true (the claim not whether he said it!)? (Over to the experts.) If it is, how might important information be passed to passengers in such a situation?
The passenger who was interviewed raised an interesting point in that he wondered exactly how hard one needs to pull on the mask to activate the flow (without accidentally snapping the tube and rendering it useless).
P.S. MOL stated (on at least three occasions, I think) that the flight was en route to Barcelona . He must have meant Girona/Gerona or Reus. I speak as someone flying to Barcelona tomorrow... on easyJet. (Sorry, MOL - I'm confident you'll read this - but I couldn't resist ! Gift horses and all that!)

At the end of the day it doesn't matter if a PA is made, or if the Pax are frightened.

All that matters is that the aircraft is made safe.

The rest is all just a nicety, if you can make a PA and calm the Pax then so much the better but not a priority.

It would seem that whenever there is a decompression that not all the masks work.

This is a little concerning.

"Baron rouge",
I've just seen your post. My understanding is that some passengers needed medical attention because the rapid descent had caused ear difficulties. I have heard of perforated eardrums in such circumstances. They were apparently advised not to fly by medical experts.

The pax oxygen system on the Rynair A/C consists of individual chemical oxygen generators in the PSUs above each row of seats. 4 masks per generator for 3 pax plus an infant. Therefore there would be no loss of pressure if they were all activated. There are many reasons why they are not. The oxygen generators get VERY hot as they produce the gas; it is also a very unpleasant, metallic smell. Having all of them on, if not necessary, would make the cabin very hot and unpleasant.

I think the Airbus can be configured to automaticaly broadcast a Rapid Descent PA in the event of sudden cabin pressure loss.

I too have wondered this, (as SLF), how hard do you have to tug on the mask to get oxygen flowing? Considering the noise and confusion, this lack of knowledge, coupled with there probably being no indication as to if oxygen is flowing seems like a flaw to me.

I would probably be so worried that I would damage the mask system that I would give it only the most gentle of tugs! I'm not too concerned though , because it seems you can go without for long enough to get to ~8000.

My parents, who supposedly listen to the saftey briefing didnt know you had to tug on the mask at all.
