that's not a cockpit error. it's a hook error, specifically as it says... MGun hook. in this error it's the DUMP hook, where the shell casings usually come out when the gun is fired. the gun hooks are in the 3D meshes in various places. in some planes they are in the wing meshes, some planes have them in the nose, on bombers they would usually be in the CF_DO or fuselage mesh where the gunner stations would be.
something's went awry somewhere, either in the meshes or i guess could be in the classfile calling for that particular hook or gun.
I was pretty certain a file was missing and did a search for the mentioned file - nothing came up though, not in any of the directories in my (huge) MODS folder, you never know if there might a similar file in another mod, just to try out. But nothing.
Has anyone else been able to fly this plane yet? I can't get it to fly neither as player, and neither, and this is more important, as AI plane ...
