The landing gear further includes an inboard sidestay assembly connected to the main strut. The inboard sidestay assembly includes a forward stay connected at one end to the aircraft, a rear stay connected at one end to the fuselage, and a shear web extending between the forward stay and the rear stay and configured to resist movement of the forward stay relative to the rear stay. The landing gear is arranged such that when the landing gear is extended substantially all the landing gear loads are transferred from the landing gear to the aircraft via one or more of the main joint, the forward stay and the rear stay. ## Claims ### Claim 1 An aircraft comprising a fuselage and a retractable landing gear, the retractable landing gear comprising: a main strut connected at one end to the aircraft via a main joint to cause landing gear loads to be transferred from the main strut into the aircraft via the main joint, and wherein the main joint permits movement in all three rotational degrees of freedom, an inboard sidestay assembly connected to the main strut, the inboard sidestay assembly comprising a forward stay connected at one end to the aircraft to cause landing gear loads to be transferred from the main strut into the aircraft via the forward stay, a rear stay connected at one end to the fuselage to cause landing gear loads to be transferred from the main strut into the fuselage via the rear stay, and a shear web extending between the forward stay and the rear stay and configured to resist movement of the forward stay relative to the rear stay; and wherein the landing gear is arranged such that, in use, when the landing gear is extended, substantially all the landing gear loads are transferred from the landing gear to the aircraft via one or more of the main joint, the forward stay and the rear stay. ### Claim 2 (depends on 1) An aircraft according to claim 1, wherein a wing is connected to the fuselage and the forward stay is connected to the aircraft at the wing. ### Claim 3 (depends on 2) An aircraft according to claim 2, wherein the forward stay is connected to the wing in the region of the root of the wing. ### Claim 4 (depends on 1) An aircraft according to claim 1, wherein the forward stay is connected to the aircraft at the fuselage. ### Claim 5 (depends on 1) An aircraft according to claim 1, wherein a wing is connected to the fuselage and the main strut is connected to the aircraft at the wing. ### Claim 6 (depends on 5) An aircraft according to claim 5, wherein the main joint is located at the front of the main strut. ### Claim 7 (depends on 5) An aircraft according to claim 5, wherein the wing comprises a rear spar and the main strut is connected to the wing at the rear spar. ### Claim 8 (depends on 1) An aircraft according to claim 1, wherein the main joint comprises a spherical bearing. ### Claim 9 (depends on 1) An aircraft according to claim 1, wherein the shear web comprises a shear panel extending between the forward stay and the rear stay. ### Claim 10 (depends on 1) An aircraft according to claim 1, wherein each stay comprises an upper portion and a lower portion, the upper portion being pivotally connected to the lower portion and the aircraft. ### Claim 11 (depends on 10) An aircraft according to claim 10, wherein the lower portion is pivotally connected to the upper portion and the main strut. ### Claim 12 (depends on 10) An aircraft according to claim 10, wherein the landing gear comprises a first shear web extending between the upper portions of the forward and rear stays, and a second shear web extending between the lower portions of the forward and rear stays. ### Claim 13 (depends on 12) An aircraft according to claim 12, wherein the second shear web comprises a shear panel having a recess configured to receive a portion of the main strut when the landing gear is in a retracted configuration. ### Claim 14 (depends on 1) An aircraft according to claim 1, wherein the landing gear comprises a trailing arm mounted at the second end of the main strut. ### Claim 15 An aircraft comprising a fuselage and a retractable landing gear, the retractable landing gear comprising: a main strut connected at one end to the aircraft via a main joint to cause landing gear loads to be transferred from the main strut into the aircraft via the main joint, and wherein the main joint permits movement in all three rotational degrees of freedom, an inboard sidestay assembly connected to the main strut, the inboard sidestay assembly comprising a forward stay connected at one end to the aircraft, a rear stay connected at one end to the fuselage, and a shear web extending between the forward stay and the rear stay and configured to resist movement of the forward stay relative to the rear stay; the method comprising moving the landing gear between an extended configuration and a retracted configuration by rotating the main strut about an axis of rotation extending substantially parallel to the longitudinal axis of the aircraft, and wherein the landing gear is arranged such that, in use, when the landing gear is extended, substantially all the landing gear loads are transferred from the landing gear to the aircraft via one or more of the main joint, the forward stay and the rear stay. ### Claim 16 (depends on 15) A method according to claim 15, wherein the length of each stay varies as the landing gear retracts. ### Claim 17 (depends on 16) A method according to claim 16, wherein each stay folds as the landing gear retracts.
