Left/Right Elevator Failure

G500 Abnormal Procedures

This is a work in progress


AFM Procedure

[AFM, §03-]

Possible Cause

The indicated elevator flight control surface is inoperative. The REUs and/or hydraulic actuators or EBHAs on the indicated elevator are inoperative resulting in a damped bypass (float) or jammed position.

System Impacts

A loss of elevator will result in reduced longitudinal (pitch) control effectiveness and degraded lateral-directional (roll-yaw) control effectiveness.

  • Steep Approach: Unavailable.

Corrective Action

  1. Autopilot . . . OFF

  2. Airspeed . . . 285 KCAS / 0.90M maximum

  3. PITCH TRIM . . . Use (as required)

  4. Airplane . . . Land as soon as practicable

  5. Landing Controllability Check . . . Perform
  6. Refer to 03-13-10, Landing Controllability Check

  7. Approach
  8. a. Runway . . . Select runway based on minimum crosswind (less than 10 knots)

    NOTE

    Use a landing distance based on VREF +10 KCAS landing speed to touchdown increased by 1.25 factor to account for the a shallow approach.

    Wheel fuse plug release may occur due to added landing speed under combinations of high field elevation, landing weight and OAT.

    b. Landing Distance . . . Recalculate with a 1.25 factor

    c. Landing . . . Use shallow approach angle

    NOTE

    Pitch trim should be used for additional pitch control authority when necessary.

    d. Airspeed . . . VREF+ 10 KCAS minimum

  9. Flare . . . Minimize
