    May be indicated through varying degrees of feedback, vibrations, binding, restriction, or sloppiness.

    Note: Blade cuff failure is typically a cord wise crack of the cuff through the blade attachment bolt holes on the upper or lower ligament.

    Warning: Danger exists that the main rotor system could collapse or separate from the aircraft after landing.  Exit when m/r has stopped.

    • 1. Possible
    • 2. Emer Eng(s) Shutdown after landing.
  2. 9.29.1
    SAS Failure with no Failure Advisory
    I e m o r t p w f/a i:
    1. S x s - O
    If condition persist:
    2. S x s - O
    3. S x s - O

    9.29.2
    Sas 2 Failure advisory lights
    • If erratic motion of rotor tip path without failure/advisory indication:
    • 1. Sas 1 switch - Off.
    • If condition persists:
    • 2. Sas 1 switch - On.
    • 3. Sas 2 switch - Off.
    • If still persists:
    • 4. Sas 1 and FPS switches - Off.
    • ----
    • Power on reset switches - Simultaneously press then release

    SAS OFF Caution Appears
    1. S 1/2 s - O
    2. F s - O
    3. L a s a p
    • 1. SAS 1/2 switches - Off
    • 2. FPS switch - Off
    • 3. Practicable

    4. L a s a p
    • 2. Power on reset - Press simultaneously then release.
    • If the airspeed fault advisory light is on, continued flight above 70 KIAS with the stabilator in the auto mode is unsafe since a loss of a/s singal from remaining a/s sensor would result in the stabilator slewing full down
    • 3. Manually slew stab - 0' if above 40 kias, use cyclic mtd stab s-u switch.
    • 4. Practicable
  5. 9.29.5

    • -cause a change in pitch attitude and corresponding longitudinal cyclic mvmt of about 1/2 inch
    • -1/2 inch lateral stick displacement, resulting in corresonding roll rate and constant hdg sideslip condition
    • -1/4 inch of pedal motion followed by change in heading trim
  6. 9.29.5
    Pitch Roll of Yaw FPS/trim hardover
    If failure occurs:
    1. P o r - p s
    2. L a s a p
    • 1. Power on reset - press simultaneously
    • 2. Practicable

    L a s a p
    • Both yaw and roll trim actuators incorporate slip clutches to allow inputs if they should jam.
    • 80lbs maximum in yaw
    • 13lbs maximum in roll.
    • Land as soon as practicable.
