An aircraft landing gear includes a sliding tube 2 having upper and lower portions 3,4. The lower portion 4 is pivotally connected to a bogie beam 6. A pair of articulation links 8,10 are connected between the upper portion of the sliding tube 3 and the bogie beam 6. A pitch trimmer assembly 12 is pivotally connected between the upper portion of the sliding tube and the articulation links. The pitch trimmer is arranged to exert a first damping force when in a first state and a second damping force in a second state. The damping element is switchable between the first and second states in dependence on the relative positions of the sliding tube and bogie beam by means of a valve 30 engaging with a valve seat 32. The apparatus is intended to prevent over rotation of the landing gear bogie immediately after take-off. |
