    Hi all. An update on todays progress for those interested. Well a very, very productive, but hard day today. We spent the day attending to our fuel leak in no1 engine bay. This involved completely defuelling the aircraft, then removing all the internal wing to wing fuel transfer pipework, to gain access the the fuel tank rear wall web plates, which had to be removed. Once removed, another baffle plate inside the fuel tank had to be removed, just so we could gain access to the nuts to lock out inside the fuel tank. All this donw through a hole 2.5 inches in diameter, blind! Only possible after spending hours pulling off lots of PRC fuel sealant!, both inside and outside of the tank.

    Some pictures from today

    ZF579 tucked up on arrival this morning. Still a sprinkling of snow.

    oops. posted too quick, more to follow in a sec

    Shortly after being uncoverd to put DC power on for fuel transfer

    power on with the gpu

    fuel transfer started to empty the wings of fuel

    The fuel coming out

    Once the fuel was taken out, all 5,500lbs of it, we were in a position to remove fuel tank web plates, pipework and enter the tanks:

    transfer pipe work and tank wall access plate removed

    http://www.gatwick-aviation-museum.co.uk/lightning/keyforumthread/offending area.jpg

    And here the problem structural plate. We removed all the offending bolts, (and nuts from the inside of the tank).

    That’s as far as we got today. Next will be to clean all the excess sealant from the area, and replace the bolts with new seals, and rebuild the fuel tank end wall plus pipe work.

    Needles to say it was a very unplesant smelly job, in an extremely confined space. Basically right arm spent in that hole for about 4 hours! its looking good to get back on track within 3-4 weeks though. 🙂

    lastly a little humourous photo for you, of us just about to blow away XN923 Bucc ! 🙂

    Matt been there mate, and converting them isnt really feasable in the space provided in the bay. We have stuck with the standard screw ons, its a pain the ass, but maybe you guys might be leaving the rig on???. By the way, the Lightning type hyd rigs are useless on the Vixen, they don’t have the bollox, We found that the only rig that had the nuts to run the Vixen system was the MK4b diesel hyd rig. Im sure there is one at Brunty, I have seen it somewhwre?

    err friendly sea vixen type couplings matt? I don’t think so, they are about as friendly as bite in the rear from a Doberman!. they are effin awful, they make a god awful bloody mess in the time it takes to unscrew the little ****es from the pumps!!

    :p shes had a warning peter!!, a real stern talking to, that’s why she’s calmed down now. She will light up alright!!, but it will be from jet fuel soaked rag and a zippo , if she pulls a stunt like that again:p she reminds us every now and then that she is a woman through and through, calling the shots!

    well justa small update for you all. you may have seen our update in the QRA thread as follows:

    “you wouldnt believe it mate. BIATCH!!! shes ready for donks and pipes, everything tested etc, hasn’t dropped a drip of fuel in 4 years, with repeated 10psi pressure cycles, then she springs a a small weep in the cold weather in december right above No1 Hot section, slight moistness. So all the bloody heat shielding and firewire out again, a total defuel to dry, all senders out, all inspection panels off of top of wing, dry air cycle rig, prc strip, dog bone bolts out, new o rings, bolts back in, re-seal, fill with fuel again, pressure cycle tests@10psi, fueldraulic rig on again. Basically Puts pay to engine fitting until late this year now, a 6 month spanner in the works! so right now, shes about as popular as a turd in a swimming pool.

    Will get some pictures for you all tommorow. But after pulling half of the no1 engine bay to pieces last week, and stripping off all the fuel sealant to the “dog bone” area of the fuel leak, I’m pleased to report that the leak is very straight forward, caused by some failed seals. We will defuel the aircraft tommorow, pull all the bolts out of the area, and replace all the seals, clean the area, fill her back up, leak check her, then re-seal the area in the next few weeks. lastly put the engine bay back together. So all being well, we should be back on schedule again within 3-4 weeks.:)

    If brian said it, you could take it as gospel. he was straight up, and as experienced as you could possibly get on Lightings. Brian confirmed that he did get to 87,000ft in an F53 in Saud. 95,000 has to be an exgeration. Brian was clear that @ 87,000 the 53 he was flying was almost uncontrollable, and wasn’t able to maintain the altitude for long.

    😀 that would be my first thaught too after the engine flamed out at 75,000! right before a brown flight suit.

    wrong.

    Not wrong at all – I’m simply stating what Lightning pilots have told me, so unless you think they’re wrong too…:p

    yes well sarcasm aside Chox, do you know much about Lightnings? I’ll go through it for you. I would like to hear a direct account from an ex Lightning pilot losing pressurisation and conditioning @ 75,000ft plus, and recovering alive, because it would be a very slim chance of survival. Which Lightning pilots would they be? Well, the ones with super human bodies that allowed them to descend for 2 minutes vertically with zero power, no cockpit pressurisation, conditioning or oxygen supply, and not fall foul to severe hypoxia? or the ones with once in a life time good fortune?

    Lets look at the scenario….

    If you lost n01 engine at 75,000ft, (your only source of positive cockpit pressure and conditioning, since n02 is dry windmilling to stop you running out of fuel) you wouldn’t have the luxury of a gradual descent to 10-15,000ft Barostatic release window for the seat. Your only option would be to point the nose straight down, and descend, dead weight/dead stick, and hope in vein that your ear drums wouldn’t explode and you wouldn’t pass out well before it was safe to open the cockpit ram air valve @10,000 odd ft. If lucky, you “might” wake up again at 15,000-ft completely disorientated, having had a slim 1-2psi in the cockpit from windmilling no1 engine, because you were also lucky enough that the airframe had remained in the right direction to keep it windmilling.

    You “might” also be extraordinarily lucky to find, that the airframe is in one piece without the fin having sheared off, and airframe came down reasonably gently, to allow your brain to fill with blood again and wake up.(unlikley, the lightning don’t fly without power, aerodynamic it isn’t!) Oh and in an attitude that allowed you to Eject or press relight buttons, assuming the puny battery in the F3/F6 had enough left to run the HE boxes, since its just supplied 4 fuel transfer pumps, the AC standby inverter, standby AI and horizon, screen and pitot heaters for the last 2 minutes. Thats on top of you feeling like you have just been punched directly in the brain a dozen times by Mike Tyson, and still being able to go over your drills.

    any ex Lightning Pilot, that managed this, ought to put pen to paper and tell the story, because that would be one hell of a lucky man and survival tale. I would take my hat off to him..:eek:

    wrong. you would be dead well before the long drop to recover from that altitude. As any lighting pilot will know from his training, the cabin pressurisation was fed mainly from N1 engine. both engines had to be managed extreemely gently, infact n02 would often be shut down once at this altitude, to avoid being fuel critical, hence the dangerous situation just running on n01, feeding your cabin air. with n01 stalled, you would pass out on the way back down, you couldn’t open up the ram air valve at such high altitude (as per normal emerg drills), as the cockpit would depressurise instantly, also killing you. This is why these climbs to such high altitude were never sanctioned, because they were extreemely dangerous. I remember Bryan Carroll telling us, that the entire time you were up at 75+000 feet, on one engine, you were aware that you were taking your life into your hands, literally.

    Nash

    Her wings had already been cut before when she was moved to Grainthorpe, XR770 on the other hand was dismantled respectfully when she was returned to the RAF late last year.

    A task which took many bodies, a crane and a couple of low loaders I believe.

    Regards,

    JB.

    well…sort of. she was still sliced to some degree..
