  • Nosewheel Steering: Unavailable.

Corrective Action

  1. If contamination of the uplocks due to ice and snow is suspected:

    1. Consider flying to an area to enable melting.

  2. If gear is fully retracted:

    1. Attempt to release from uplocks by applying positive ’g’ loading not to exceed 2.5g (flaps up).

  3. If gear is partially extended, but not locked down:

    1. Plan a normal approach to a firm main landing gear touchdown immediately followed by go-around to jolt nose gear down and locked.

    2. (1) Airspeed . . . Maintain VREF +10 KCAS

      (2) POWER LEVERS . . . Maintain above idle

      (3) At Main Gear Touchdown

      (a) Pitch Attitude . . . Maintain landing attitude

      (b) Go-Around . . . Execute

  4. If nose gear is not confirmed down and locked, begin the following landing procedure:

    1. Runway . . . Select longest available

    2. Ldg Gear Horn (TSC/Aural Inhibits/ TAWS) . . . Inhibit

    3. Normal Approach and Landing . . . Conduct

    4. Touchdown . . . Runway centerline

    5. NOTE

      After airplane nose gear contacts runway, weight can be relieved with aft stick and nose up trim.

    6. Airplane Nose . . . Control descent onto runway

    7. Wheel Brakes Use minimum acceptable

    8. Directional control and stopping:

    9. (1) Rudder and Differential Brakes . . . Use
