There are no jam nuts on the tail rotor blades, but there are similar nuts called Pal nuts

• There are two bolts that that go through the blades to attach them to the hub

• On the opposing end, there is a standard nut

• On the outside of the standard nut is the Pal nut, which prevents the inner nut from loosening

Ensure the Pal nuts are tight/secure

Ensure the torque stripes are in a continuous line and not broken
