I know this sounds crazy, but the simple 'steel and cyanite' recipe for the rotor blade and rotor shaft won't show up in the crafting interface, and when you manually try to put the parts in, it comes up with Spaghetti and Meatballs from Pam's Harvest Craft.

There isn't an ID conflict as near as I can tell; it's a matter of there not BEING an ID for the rotor shaft or blades at all, so you can't bypass and put them in with creative mode either.

This is almost certainly a mod interaction. Are you using a custom modpack? Which version of BR is involved? (I assume 0.3.0A)

Does this happen if you install only BR and Pam's Harvestcraft together?

No further information for a week, closing.
