The Sioux City crash fan disc was 17 years old.... it had already been inspected before during engine overhaul, but was still short of its life limit.
No, LL parts cannot be run on condition after the limit expires.
"On condition" maintenance requires there be a way of inspecting parts in service (i.e. borescope inspecting blades/combustion chambers etc.), or monitoring them (i.e. engine condition monitoring of EGT/vibration/Fuel flow etc.) to show signs of degradation & impending failure. As these bits either work as advertised or fail catastrophically without warning they are replaced after a set number of hours/cycles operation during shop overhaul.
From what I've read of XH558, although a permit to fly aircaft, the CAA are making them operate it as per an airliner.
I guess the CAA are less worried about your lycomming dropping onto 5 pots as you potter around the skies than an olympus grenading over an airshow crowd?

Just stumbled on the thread!
I know I'm pretty young, (23, awwww, LOL!), and I am not in any way an aircraft 'buff', but...
My granddad worked on this very plane, XH558, at Bruntingthrope, for about 10 years. I can't be totally sure how long it was. He was in the RAF (albeit just as long as his national service required), and had a love for aircraft. And obviously, very patriotic! He worked for free, or very very little pay, but loved it all the same.
Going back quite a few years now, I had the pleasure of sitting in the cockpit! It was on stands, and was only partially constructed, but it's still über cool!
I really REALLY hope this goes on to fly for a long time.
Anyway, I've wrote a bit and not actually said anything, lol.

I recall that they started with a pool of 8 zero houred engines - and as of last year they were down to 6 airworthy ones.
Vague recollection though - happy to be corrected on any of the above.
That's about right, although I do believe, that, while one of the original 8 is now dead, the 7th is a 'maybe' for a possible repair.Vague recollection though - happy to be corrected on any of the above.

She did a fantastic flypast at Cosford today. Shame we only got two passes before it buggered off.
Lovely though.
558 flew over the National Arboretum in Shaffordshire as they unveiled the Falklands MemorialLovely though.

Saw her yesterday at Donington Park as well. You kind of get used to the roar of jet engines at Donington so it was a bit of surprise when the missus nudged me and pointed her out coming in low over East Midlands airport. Half an hour later and she was back once again doing a low pass over the airport before banking north and I guess heading for home.
It was an odd manoeuvre that she did over EMA as on approach she was so low that from my position on the infield at Donington it looked like she was taking off and on the return it looked like she was landing which even prompted the missus to ask why the landing gear wasn't down.
My guess is it must have been a fun little flyby for the ATC at EMA or even perhaps the airpark where there is a static Vulcan. Imagine being in the ATC tower and being buzzed by a Vulcan!

"Tower, this is Ghost Rider requesting a flyby.""Negative, Ghost Rider, the pattern is full. "
He'd spill more than his coffee if it did

More likely what Mutley said above:It was an odd manoeuvre that she did over EMA as on approach she was so low that from my position on the infield at Donington it looked like she was taking off and on the return it looked like she was landing which even prompted the missus to ask why the landing gear wasn't down.

The emotional service at the National Memorial Arboretum in Staffordshire, attended by hundreds of current and ex-services personnel and their families, ended with a fly-past by a Vulcan bomber and three military helicopters.
Not so far away from Donington.

I saw it on the news as well so figured that was where she was going. I certainly didn't think Donington Park had booked her to entertain the few dozen people that can be bothered to turn up for what was essentially a club meeting.Mutley said:

Next time you see Martin Withers, ask him what it's like to fly a Vulcan down the Grand Canyon at below rim height.

Yes, Martin Withers was flying yesterday and was the one who piloted the first Black Buck mission in the Falklands.
More by luck than judgement though! 
Would have been nice if one of the Military Helicopters was "Bravo November" but I beleive that is (or certainly was) in Afganistan
