This work aid is used to stop the tail rotor from flapping when checking the blade pitch angles. This is used in conjunction with the 407 tailrotor rigging block which is used to check the pitch angle.
Bell P/N 407-99-26-101 found in ASB 407-99-33.
If you do not want to cut the safety wire and remove the tail rotor mast nut, we have designed our own version of a flap stop that we feel works better. Check it out here.
