The frangable fitting is there to prevent the rear spar being ripped open in an accident. The fitting will fail first and thus prevent a fuel spill.

It just a designed weak point in the structure that breaks at a predetermined load

VC-10 i am not sure you ansvered this one corect.

"The frangible fitting removes up pressure from the main landing gear actuator when a dameged, spinning tire moves into the main gear wheel well. This prevents damage to compenents in the wheel well."
this was taken directly out of a 737 book

it is just a small fitting installed right besides where the wheel moves into the wheel well. the fitting is conected to the up presure line to the main gear actuater, and if a spinning dameged tire hits it, it will bleed the press to the actuator and a fuse will close, and the gear will stay down.
