Tmbstory, Thanks for the stories 
Might help some of us down the road sometime with a similar problem and it's reminder for us to check our oxygen masks regularly.
Whatever the root cause, it would be good reason to don the oxygen mask 
Cheers,
Chips

it sounded like someone with a severe bout of flatulence

C550 @ Fl410
LFS:
"So you were flying a straight Citation II at FL410?
"
What an odd thing to say. It'll get up there OK, provided you don't wring it's neck in the climb and step up properly. Hell, we used to do it regularly in the C500, let alone the 550!
Not something I like to do regularly these days mind, as here in Euro land it doesn't give you too many sectors until you hit the 1 mSv "glow in the dark" limit.

Sepp, you get lots of provocative comments like that here on PPRUNE that don't actually add anything to the thread. Best to ignore them and hope they go away.

Flight Level 410 and down!
Look for Shooter:
Sure was until I had to go down.
It would have been nice if the wings were swept, however I did not want that to happen on the way down.

Not to be provocative...but taking a C500 to FL410, is a slow, slow, time consuming practice, that practicaly negates any range/performance benefits...doing it on a regular basis? Not with me on board...you'd be sitting on the lav...I want to get there some time today...

Today may be, but 20 years ago, this was the key.. Especially with the long wing and the -B engines. Remember, this was a time of no RVSM, NO TCAS, NO TAWS, no 8.33Khz; no TSA, no yellow jackets, Very few airport slots, JetA1 at 70cts/USG. No radiation detection on arrival, able to load a nailclip or a weatherman multitool in your flight case without being a terrorist.. Still aviation of the olds days.
Yes the 501 would go to 410; yes it was necessary under certains circonstances, yes FAR25 aircrafts are flying by the book..; If they do not in someone hands, one's should look at the operating habits.
The depressurisation happened to me on a 501 twice for the same reason but on a different aircraft, once at FL350, the other one at FL390..this was back in 1990; door Seal...
The Ops guy, (if he reads this post), gave me as a birthday present a little box, with plasters and bathroom sealant to cure the leaks, LoL...
By the way , this was in U.K. ; Home of the Comet....
since then....

I've heard many jokes about the englishman, irishman and the scotsman but not the one about a depressurised (american built) aircraft flown by a frenchman in the UK. What's the punchline then?

It's probably a little unfair to accuse someone in here of not having 'flown on a regular basis up to FL410 in a C500' but then again I could tell you that I had flown the SR71, was an astronaut, helo pilot, and did carrier landings in Harriers for fun...Peer review is the word here...but as I remember someone saying, it's usualy 95% of the people are wrong, that's why only 5% are truly successfull. Personaly when I fly in the upper thirties and above, I start factoring in the range benefit vs the depressurization risk. Fuel prices being what they are though, I imagine anyone who wants to keep thier job is flying as high as practical. But you can fly a plane so high that it starts to go so slow it doesn't make sense...only topping thunderstorms seems to be the valid reason in this case, and they don't happen on a 'regular basis'.
