A load introduction element for a movable surface of an aircraft comprises a load introduction body that is connectable with the surface. A fitting connected with the load introduction body with a first section and a second section. The first section comprises a first bearing means, the second section comprises a second bearing means, and the first or second section comprises a third bearing means. The fitting is pivotally connected with the load introduction body by way of the first bearing means. An adjustment unit connects the second bearing means with the load introduction body in a variable position and is positioned on a side of the load introduction body that is opposite the fitting. In this manner adjustment of a reference position of a surface takes place without the need for an access flap. By loosening the adjustment unit the movable surface is pivotable without moving a flap drive.

1. An aircraft comprising: a moveable control surface component having a top outer surface and a bottom outer surface; anda drive unit configured to move the moveable control surface component;the moveable control surface component further comprising: a support rib;a fitting connected to the support rib and having a portion extending above the top outer surface of the moveable control surface component, the fitting comprising a first section and a second section opposite the first section; andan adjustment screw positioned through the support rib and exposed through the bottom outer surface of the moveable control surface component;wherein the first section of the fitting comprises a first bearing, the second section of the fitting comprises a threaded connector that is pivotally mounted in a seat of the fitting, the threaded connector engages the adjustment screw, and the fitting is pivotally connected to the support rib to pivot on an axis of the first bearing; andwherein an angular position of the fitting relative to the support rib is adjusted by way of the adjustment screw, wherein adjustment of the adjustment screw causes the fitting to pivot on the axis of the first bearing. 2. The aircraft of claim 1, wherein the threaded connector is a barrel nut that comprises an internal thread with a longitudinal axis that is perpendicular to a longitudinal axis of the seat in the fitting. 3. The aircraft of claim 1, wherein the fitting comprises a first supporting surface on a side of the fitting that opposes a second supporting surface of a variable end stop, wherein the second supporting surface rests against the first supporting surface. 4. The aircraft control system of claim 1, wherein the support rib comprises a holding element that extends to the fitting, and wherein the fitting is connected with the holding element by way of the first bearing. 5. The aircraft control system of claim 4, wherein the first bearing is arranged outside a profile of the support rib. 6. A system for an aircraft, the system comprising: a moveable control surface component having a top outer surface, a bottom outer surface, and a support rib;a fitting comprising a first section and a second section opposite the first section, the fitting extending above the top outer surface of the moveable control surface component, the fitting pivotally connected to the support rib to pivot on an axis of a first bearing in the first section, and the second section comprising a seat formed therein;an internally threaded connector pivotally held in the seat formed in the second section of the fitting; andan adjustment screw having a first end removably connected to the internally threaded connector, and having a second end exposed through the bottom outer surface of the moveable control surface component, wherein adjusting the adjustment screw causes the fitting to pivot on the axis of the first bearing by displacing the internally threaded connector and the second section of the fitting, relative to the support rib, to change an angular position of the fitting relative to a profile chord of the support rib. 7. An aircraft control system, comprising: a moveable control surface component comprising a top outer surface, a bottom outer surface, and a support rib;a fitting connected to the support rib and having a portion extending above the top outer surface of the moveable control surface component, the fitting comprising a first section and a second section opposite the first section;a first bearing in the first section of the fitting, wherein the fitting is pivotally connected to the support rib to pivot on an axis of the first bearing;a second bearing in the second section of the fitting, wherein the second bearing comprises a first threaded connector that is pivotally mounted in a seat of the fitting;a third bearing in the fitting, the third bearing connected to a drive unit for the moveable control surface component; anda second threaded connector positioned through the support rib and exposed through the bottom outer surface of the moveable control surface component, wherein the second threaded connector is removably connected to the first threaded connector to adjustably connect the fitting to the support rib in a variable position, wherein adjustment of the second threaded connector causes the fitting to pivot, relative to the support rib, on the axis of the first bearing. 8. The aircraft control system of claim 7, wherein: the first threaded connector comprises barrel nut that comprises an internal thread; andthe second threaded connector comprises an adjustment screw that threads into the barrel nut. 9. The aircraft control system of claim 7, further comprising a variable end stop having a supporting surface, wherein the second section of the fitting comprises a support surface that opposes the supporting surface of the variable end stop, and wherein the support surface of the second section of the fitting rests against the supporting surface of the variable end stop. 10. The aircraft control system of claim 7, wherein the third bearing comprises a spherical bearing. 11. The aircraft control system of claim 7, wherein the third bearing comprises a pivoting bearing.
