Nutcracker System Fails To Shift To Ground Mode At
Touchdown AFM 3-19-40
For airplanes with ASC 166:
1. Red REV UNLOCK message will illuminate with the use of thrust
reversers. Thrust reversers will stow at low ground speed.
2. Ground spoilers will deploy with wheel spin-up, but will retract at low
ground speed.
3. Anti-skid system may not operate normally. Be prepared to turn
anti-skid off at low ground speed if you lose brakes.
4. Engine idle will go to 67% HP at low ground speed.
5. APU air is inoperative.
6. Pressurization outflow valve will not open automatically. Switch to
manual and open outflow valve.
7. Stick shaker and pusher remain armed.
8. Landing gear handle is not safe (safety solenoid energized).
9. Engines cannot be restarted.
