Methods and apparatuses for rotatably supporting movable components, including canards. An apparatus in accordance with one embodiment of the invention includes an airfoil configured positioned external to an aircraft fuselage. A connecting portion can depend from the airfoil portion and can have an attachment portion configured to attach to an aircraft internal to the aircraft fuselage. Rollers carried by one of the connecting portion and the fuselage can rotatably contact a track carried by the other of the connecting portion and the fuselage.

We claim: 1. A method for servicing a roller arrangement positioned between a first structure and a second structure to allow the second structure to rotate relative to the first structure about a rotation axis, the method comprising: accessing the roller arrangement, the roller arrangement including an arcuate track coupled to one of the first and second structures, and a roller support coupled to the other of the first and second structures, the arcuate track having a web portion carrying a flange portion, the flange portion having a contact surface, the roller support carrying a first roller with an external surface in load bearing contact only with the contact surface, and a second roller with an external surface in load bearing contact only with the web portion; removing one of the first and second rollers from the roller arrangement without removing the other of the first and second rollers; and replacing the one of the first and second rollers with a replacement roller. 2. The method of claim 1 wherein the first roller is carried by a pin and wherein removing one of the rollers includes removing the first roller and the pin. 3. A method for servicing a roller arrangement positioned between a first structure and a second structure to allow the second structure to rotate relative to the first structure about a rotation axis, the method comprising: accessing the roller arrangement, the roller arrangement including an arcuate track coupled to one of the first and second structures, and a roller support coupled to the other of the first and second structures, the arcuate track having a web portion carrying a flange portion, the web portion having a first surface and a second surface facing opposite from the first surface, the flange portion having a contact surface, the roller support carrying a first roller with an external surface in load bearing contact only with the contact surface, a second roller with an external surface in load bearing contact only with first surface of the web portion, and a third roller with an external surface in load bearing contact only with second surface of the web portion; removing one of the second and third rollers from the roller arrangement without removing the other of the second and third rollers; and replacing the one roller with a replacement roller. 4. The method of claim 3 wherein the roller support includes a first bracket portion carrying the second roller and a second bracket portion carrying the third roller and wherein removing the one roller includes removing the second roller and the first bracket portion. 5. A method for servicing a roller arrangement coupled between an aircraft fuselage and a connecting portion connecting an airfoil to the fuselage to allow the airfoil to rotate relative to the fuselage about a rotation axis, the method comprising: accessing the roller arrangement, the roller arrangement including an arcuate track having a first contact surface coupled to one of the fuselage and the connecting portion, the roller arrangement further including a second contact surface generally normal to the first contact surface and coupled to the one of the fuselage and the connecting portion, the roller arrangement further including a roller support coupled to the other of the fuselage and the connecting portion, the roller support carrying a first roller with an external surface in load bearing contact only with the first contact surface, and a second roller with an external surface in load bearing contact only with the second contact surface; removing one of the first and second rollers from the roller arrangement without removing the other of the first and second rollers; and replacing the one of the first and second rollers with a replacement roller. 6. The method of claim 5 wherein the first roller is carried by a pin and wherein removing one of the rollers includes removing the first roller and the pin. 7. A method for servicing a roller arrangement coupled between an aircraft fuselage and a connecting portion connecting an airfoil to the fuselage to allow the airfoil to rotate relative to the fuselage about a rotation axis, the method comprising: accessing the roller arrangement, the roller arrangement including an arcuate track coupled to one of the fuselage and the connecting portion, and a roller support coupled to the other of the fuselage and the connecting portion, the arcuate track having a web portion carrying a flange portion, the web portion having a first surface and a second surface facing opposite from the first surface, the flange portion having a contact surface, the roller support carrying a first roller with an external surface in load bearing contact only with the contact surface, a second roller with an external surface in load bearing contact only with first surface of the web portion, and a third roller with an external surface in load bearing contact only with second surface of the web portion; removing one of the second and third rollers from the roller arrangement without removing the other of the second and third rollers; and replacing the one roller with a replacement roller. 8. The method of claim 7 wherein the roller support includes a first bracket portion carrying the second roller and a second bracket portion carrying the third roller and wherein removing the one roller includes removing the second roller and the first bracket portion.
