I've always wanted to build down, instead of build up. Just somewhere other than Coober Pedy.

In regards to building down, is there a spider table in Australia, like there's a water table here in South Florida

I would just imagine that any hole you dug would immediately fill with venomous local fauna.

Any goons here that work in aircraft maintenance? I attended a little talk at work a couple of weeks ago that talked about how the designers took "maintenance" and "what is humanly possible" and no part exists in isolation" into account when designing systems, fastenings, plumbing, routing etc. It was all very interesting & they showed some cad walkthroughs of an engine mounted on a wing, maintenance doors opening, human arm and recommended tool comes into view, bolts & brackets get removed, parts come out & in again.

Basically is that how it is in real life?

See if you can find the 777 anti collision light example. The 777 was designed from scratch on CAD and they did include a little human figure to see where arms can reach and what can be accessed with what range of motion and what physical strength and so on. They still managed to build the dorsal (or maybe tail) strobe light so the bulb could only be access from inside the dome but outside the pressure hull - so you'd better hope the thing lasts 20-odd years because there is literally no way of accessing it. I think there was something similar with the 787. The system exists but it isn't fool-proof.

(They ended up doing an absurdly expensive retrofit to access it, but after the production line was in full swing)

I used to be a line mechanic, and I can confirm that it is light years better on newer airframes than on older ones. That said, there's always Douglas products. :suicide:

That reminds me of a problem we solved at work. On the CFM56-5A engine, there is a turbine clearance control valve, called the HPTCC. It bleeds air from the compressor to shrink the case around the turbine for efficiency.

Sadly, being buried on the case since it bleeds right off, you had these four bolts which heat soaked and cooled, so they were stuck in good, always had to use anti-seize to get em out. But you had no direct access to remove and install the bolts. Eventually we had an intern jig up a torque wrench extension and do all the calculations cause the CFM tool was too expensive.

located pretty much dead center in the middle, opposite side by its just as spaghetti there as it is here.

drat thing also had a gasket that would leak and set of engine fire warning. yay those were fun to deal with.



It's such a CUTE little engine.

Each engine has two hydraulic pumps a primary, and a backup, and the garlock seals on the primary pump failed in a rather spectacular fashion, which let the pump dump the entire contents of the #3 hydraulic system into the engine main gearbox.

Kicker A: The flight crew saw the engine oil temp go up, but didn't want to declare an emergency or do the paperwork that a shutdown would have called for, so they just yanked it back to flight idle, and flew it another three hours home. :cripes:

Kicker B: GE technical services had us change the oil, run it for half an hour, change the oil again, and then test fly it, and signed it off, despite three hours of operation with hydraulic fluid for oil. :catstare:

But at least Optisparks had a breather hole, so if when it got coolant in it, it could vent out clog up, and essentially make a tiny coolant sauna for the delicate optical rotor.

They got slightly better when they went to an engine-vacuum connected vent in '95, but the best thing to do with an gen II at this point is to replace it with a gen III/IV, anyway...

The last time I tried taking Craftsman tools back for replacement I got a remanufactured socket wrench that broke a week later and they wouldn't replace my screw drivers because they were "clearly used for things other than just turning screws".

That was 9 years ago and I haven't touched Craftsman since. Maybe they've changed their policies since then?

I used to have an older 1/4 drive ratchet that was amazing. It had a very fine ratcheting action, and I couldn't break it if I tried. I'd put some of the older Craftsman stuff up against SnapOn any day.

When it grew legs out on the ramp one night, I replaced it with a new Craftsman. What a piece of poo poo. It had like eight clicks for 360 degrees, and it broke the third time I used it.

Impulse magneto :eng101:

Oh God that reminds me of a stupid game we played when I was getting my private pilot license in the Air Cadets. The flying school we used had a cutaway Lycoming O-320 (the same engine as in most Cessna 172s) that had a live magneto attached to it. So being a bunch of stupid teenagers we'd get four guys to grab an ignition wire and a fifth to hand-crank the engine until someone had received enough shocks that they cried uncle or dropped their wire.

This is why you don't let pilots in the hangar...
