Default F407 bulkhead

Hi Everyone

Any idea why all the bulkheads are notched for the main longeron except for the F407?

Thank you

Default 407

the main top longeron goes over the top of the 407, there's depressions in the top bulkhead for them. The other longerons stop at the rear seat bulkhead.
The forward longeron that is angled to the firewall is milled/filed to fit flush with the doubler, so it overlaps to pick up the vertical rivet line. (doubler where the spar comes out) hope this helps.

Default oops

I just remembered the forward, lower longerons that go to the lower engine mounts come pre-bent from Vans to fit flush with the outside skins.
So there is no notch in 407 from them. its been 33 years since I built mine so......
