    Clean and inspect it regularly, like the rest of the fleet! You would imagine that there was some laquer or varnish used but there aint. All the fleet started out that shiney but the surface of the alclad dulls with time due to oxidation. It is in fact a very thin layer of surface corrosion. To shine one up you basicaly remove this thin layer of oxidation. If you did it often enough you would polish your way through the skin though! That is why AA doesn’t do it every week. This finish will last a few years but will be slowly revert to the same dull silver as the rest of the fleet.
    I wonder what colour the AA plastic pigs will be?

    There was an Etihad one in last month picking up some football team or other. It wasn’t United so I wasn’t interested.
    Etihad had one divert in last Christmas day. Lufty and Virgin have also diverted ones in over the years. Nice to see it though.
    Don’t know why this one turned up. Nobody involved with it knew why either!

    With those winglets and no actual fuselage paint to weigh it down …it must be the cheapest ship to run in the AA fleet

    I’ve been told they have to DRAIN fuel off it after every flight!;)

    Pitty they couldn’t have one with a huge scab patch on though!

    I remember they sent one of their “New” 767 through a few summers ago. I WAS diificult to look at close up due to the sun light!

    Wow thanks chaps!
    Creaking door. You mention the Napier Sabre’s complexity. My apprentice master at Farnborough worked on them for a short while after the war. He recalls them as being a nightmare to keep working well and said that nobody was either sad or surprized when they were withdrawn! It makes me smile when people sugest say thaey want to get one airworthy again.
    Hears a question How many Sabres exist today?

    Cking is right about accessory quill shafts, but the true meaning is a floating shaft, usually splined at both ends which connects two items together each of which is supported in its own bearings, and this allows for differences in alignment and thermal expansion. The bloody great quill which couples the crankshaft to the reduction gear for example, is not necked down.

    I wonder why they are called “Quill drives”???? Designed by Mr Quill?? made by Quill and son’s???
    Interesting to hear of a shaft inside the engine called a quill though. My knowledge of the inside of a Merlin is…..well….er…..nil!:D
    Perhaps it’s one of those terms that has become *******ized over the years.
    Thanks for tha info

    I must admit I couldn’t think af a good reason why the crank would need to be different but assumed I must have missed something.

    Pete, as the resident expert, what’s a quill shaft?

    Not Pete but…
    A quill shaft is the small shaft between the engine accessory gearbox and an accessory ie the hydraulic pump. It has a weak point in it so that if the accessory seizes the shaft shears to protect the accessory gear box.
    As for “lefties” and “righties” it is usualy just the very last bit of the gearbox that turns the other way UNLESS you have a P-38, then the whole thing turns in a different direction!. Supposedly you can change one to another but it involves stripping it down into tiny pieces in an engine shop.

    So, this is a “Bog Thread”, is it? Well that’s nothing. Imagine doing a tour round Central Africa, tropical temperatures, and not visiting a maintenance station for a few days. Man, those toilets start to hum after a while! No grounding the plane. You finish the tour of duty, or, as we once did out of desperation, park at the far end of a remote runway and open the drain valve…

    “Thats nothing, that”!
    A mate of mine dismantled a Tristar at Bournmouth years ago. When they came to remove the forward bog tank they had to up end it to get it out of the forward lower hatch. He thought it looked a bit heavy as his two mechnics struggled to lift it. The two guys BELOW the forward lower hatch had the contents of the tank emptied onto them. The tank had not been emptied when the aircraft landed there THREE YEARS previously!!!!

    Toilets are a source of endless fun. In fact it is part of an Aircraft engineers creed that when ever more than two of us are gathered together we will always end up talking about blocked bogs. We all have a good “Bog story” and after telling it it is the rule that somebody else tells another starting with the line “Thats nothing, that!”
    Quite a few years ago there was another Bog thread running on the forum.

    Towards the end of it I discribed the two systems used on airliners. all new Airbus and most new Boeings have vacuum toilet systems.

    They all have a vacuum toilet system fitted.
    They ALL have the same problems.

    I was on a course with KLM at Norwich a few years back and the instructor there told us that the 777 had to have bends put into the poo pipes because such a long straight section, when tried on the engineering mockup, let to the t*rds going supersonic and smashing their way out at the far end. 😮

    They use a synthetic block for testing, in case anyone’s wondering. 😉

    Did they reach Turdinal velocity?

    it was always a ground engineer who ended up with one arm stirring the poo to clear the exit valve of the waste tank.

    Been there, done that!
    It’s amazing how health and safety rules don’t seem to apply to us engineers:confused:

    I’d love to know how they got the freight doors open underwater. To un lock then is no problem, the latch and locks are manual but they are hydraulicly opened.
    The rear one is in the position I’d expect if the door had been un latched and un locked but the forward one has been fully opened and locked open. I can only assume that a team of frog men found the manual pump amd pumped it open. It’s hard enough when you do it on the ramp but underwater???
    It will be on “Mega movers” or recovery squad at some point
