Special Aircraft can only level up to 10 with credits and research. Once you hit 10, you need to start spending Lv Cap Increase Request Forms every level on top of the credits and research. Some aircraft can go past 10 without those forms, but all Special Aircraft require those forms to eventually hit 20.
