or more specifically which side of the undercarriage is best for structurally maintaining the strength of the fuselage?
I know most of the old Binbrook lot were cut outside the undercarriage but what would happen if one was cut inboard of the gear?
no Iām not cutting one up just curious

Time wasn’t on XS417’s side – I did even try to get it ‘lifted’ from Binbrook to Newark by the USAF and British International Helicopters, but again timings weren’t on NAM’s side! š
That said – even now XS417 is still helping live airframes!! š

Inboard or outboard, it’s still a stupid choice. That’s why God made transportation joints.
As a principle I wholly agree, however there is not always the luxury of the time, facilities or kit to undertake the ‘right way’ of dismantling. If its a choice between loosing an opportunity or judicious cutting which do you choose?
Back to the question – always outside the undercart if at all possible, then you only have to re-hang and support a section of wing. Inboard you have to ensure you have enough structural reinforcement to hold the weight of the entire aircraft.
Lightning XS919 was cut inboard of the wing and ended up with a support structure under the belly; similarly the poor old Balderton A1 example had a support structure. Lots of the ex BAe and Binbrook examples in museums were cut outboard and as a result you would be hard pressed to even notice they had been cut at all.

You can get an idea of the cut on Newark’s T5 XS417 if you look in the Collecting Aeroplanes album in this Gallery – I believe that it was cut differently to most of the other Binbrook machines! š

Well i would say outboard, reason being the weight of the aircraft needs to be supported, the gear does that, so cutting outboard of it the structure that supports most of the weight is intact, also the outboard section would also be lighter so requiring less of a repair to support it’s weight.

I don’t know the Lightning, but cutting the wings off anywhere would not affect the structural ridgity of the fuselage. Even if you chopped the spars immediately before the wing/fuselge joint, the spar box would still provide all strength in the fuselage.
The problem would come if you tried to re-attach the wings – your repaired spar would most likely not hold the weight of the fuselage. If you cut the wings off inboard of the MLGs, it’s permanent…..
