this time it was no longer a paratrooper man o war 
i think i found the solution (i have a working version), but the explaination why is a bit guessing. I think the problem was the SkinPartition and the used shader. The model was a non shader version (SkinPartition with max 4 bones) and had also the meshNonShader 'shader'. The reason should be to be able to have the damage stats and texture.
While with Blender and Nifscope afaik we can´t create nonshader skinpartition, i have no idea if it´s possible with max, but having wrong skinPartition can (i think i had such a case also in past) cause the observed bahavior, some parts are animated, other aren´t.
Making the model a 'real' shader model and all woked like it should (cannons go first while fortifying in fire position, cannons are moved back by the punch - just for testing purpose renamed the file to 'frigate_fx.nif'). While for the shader model it work fine, for the nonshader version you can try to remove the skinPartition (and lose the damage texture - but the also work without them)
