Jammed Spoiler

G500 Emergency Procedures

This is a work in progress


AFM Procedure

[AFM, §04-13-40]

Possible Cause

A spoiler is jammed in a fixed position due to mechanical interference or internal actuator failure.

System Impacts

Jam of a spoiler surface will result in reduced lateral (roll) control effectiveness, reduced speedbrake effectiveness and reduced ground roll braking effectiveness.

Corrective Action

    NOTE

    To view the FCS Synoptic Legend, refer to 03-13-190, FCS Synoptic Legend.

  1. Autopilot . . . OFF

  2. Configuration / Airspeed . . . Maintain current configuration and safe airspeed (285 KCAS / 0.90M maximum)

  3. ROLL TRIM . . . Neutralize roll control forces

  4. NOTE

    The speed brakes may be deployed as required to attain a more symmetric lift distribution on the wings.

  5. Airplane . . . Land as soon as practicable

  6. Destination Airport . . . Select longest and widest runway available with minimum crosswind component

  7. Landing Controllability Check . . . Perform

  8. a. Refer to 03-13-10, Landing Controlability Check.

  9. Landing Configuration . . . Plan flaps 20° landing

  10. GPWS FLAP INHIBIT . . . Select

  11. NOTE

    Landing distance should be based on a flaps 20˚ landing maintaining VREF +20 KCAS to touchdown. Wheel fuse plug release may occur due to added landing speed under combinations of high field elevation, landing weight and OAT.

  12. Landing Distance . . . Calculate

  13. Airspeed . . . Maintain VREF (20° flaps) +20 KCAS minimum

  14. Landing

  15. a. Landing . . . Lower nosewheels to runway without delay

    b. Thrust Reversers (Left and Right) . . . Deploy
