Pitch link jam nuts

  • Locate the main rotor pitch link jam nuts

    • There are two nuts on each adjustable pitch link

    • This inside nut is the jam nut, which prevents the link from loosening

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

  • Ensure the jam and pal nuts are tight/secure

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