The German military in 2017 could probably not stop an invasion by Canada. NATO on the other hand, most certainly exists to deter Russian aggression.
The Canadian army would struggle to invade a locked Tim Hortons. Germany might not be ready for Barbarossa 2: Electric Boogaloo, but they maintain one of the larger and arguably better equipped militaries in Europe.

During the D maintenance, every part should be inspected. Things like fuel lines should be inspected much more regularly, ideally more often than it would take to rub through a fuel line. But a visual inspection on a fuel line can be really difficult. I had a motorcycle with a leaky fuel line once, luckily it sprung a leak while warming up in my driveway and I turned off the bike before anything bad happened but it w…
If the 6 million parts figure is correct, it's obvious that it is not possible to inspect every part of a 747. Suppose we allow 1 minute per part inspection. Then that's still about 11 years of inspection time (without taking any breaks!)
Also, that part count is probably inclusive of the engines and avionics and those are inspected on separate schedules by separate technicians. Lord knows how many parts are on a 747 circuit board, but as long as the board is working correctly, do you need to check every capacitor on the board?
The D service also takes tens of thousands of hours and months - each panel is removed and every inch of the aircraft is inspected by master technicians and factory representatives. IT can only happen at special factories that have the space for the plane to come apart and come back together like it should.
Same two contenders as the original competition in 1965! Significantly updated but still disappointing in showing how little aerodynamics has progressed in five decades.
Also curious: why no other contenders, especially the Russians? Procurement politics is heavy stuff.
why not invest into it. basically I already now the answer. but it's a shame.. (they probably want another disaster after eurofighter/eurocopter/whatever every project where the german governement was directly involved failed, wasn't working as expected... (g36 precision...), or costed a lot more than calculated (not just inside the military..))

I believe that B747 do get regularly tear down. They basically remove all the cabins, lots of the conduits and wires, remove the instruments in the cockpit, inspect hidden areas, and reassemble the whole thing. https://en.wikipedia.org/wiki/Aircraft_maintenance_checks#D_...
A tear down doesn't necessarily involve inspecting every part.

So far as the HH-53 (the USAF version), when I rode one in the 80's, the saying was that if it wasn't dripping hydraulic fluid, there was something wrong.

They inspect pretty near every part on a 747 during a D check. Including the toilets. https://youtu.be/x_yHtfGH0nI?t=36m55s So far as the HH-53 (the USAF version), when I rode one in the 80's, the saying was that if it wasn't dripping hydraulic fluid, there was something wrong.
Why don't they pick H225M Caracal?
This scrap is not flying. French army has them and 75% of them are broken. They don't repair them because of high maintenance costs. https://www.latribune.fr/entreprises-finance/industrie/aeron...
