The wings and tyres of the MC-21 seems to be sanction-proof now. The development of tyres started actually already in 2016.



Today a KLM Boeing 777 had to RTB/return to the airport of departure, Amsterdam Schiphol (AMS), because of a technical problem on engine nr.1. On the other side of the world, another Boeing of KLM, this time a 787, had also technical problems and was also forced to do the same and return to Tokyo.

This is really a disgrace if this is all true.

This can be complicated. I remember many years ago there was a coffee maker, IIRC in an AWACS, which was supposedly massively overcharged for. It turned out that the USAF had written a specification for it that took many thousands of words, specifying that it should remain functional in conditions that might have destroyed the aircraft. Boeing had to design such a coffee maker & test it. Most of the crazily high price was in the very expensive design & testing, spread across a very small production run.

I have no difficulty in believing that Boeing overcharges, but US military procurement can make things that one would expect to be cheap very expensive indeed. They can demand extreme performance, whether it's needed or not, so a unique product is needed, & exhaustive testing for everything, & often, only buy small numbers.

P.S. I've just noticed something else. Imagine a custom-designed piece of equipment, made in one small batch. You have to buy all the spares you're ever going to need in one go, or make provision for manufacture of new spares. Either is costly. In 2020 the USAF issued a requirement for a new coffee maker for the E-3, because spares for the old one were no longer available. ;)
