The invention relates to a fairing
system for an aircraft horizontal stabiliser and to a method for installing said
system, such that the fairing
system for sealing the horizontal stabiliser (2) and the
fuselage (1) of the aircraft includes a primary fairing (50, 51) arranged on the horizontal stabiliser (2) of the aircraft, said primary fairing (50, 51) being rigidly connected to the aforementioned horizontal stabiliser (2) which, in turn, is trimmable relative to the
fuselage (1), said fairing system in turn including a secondary fairing (80, 81), such that the primary fairing (50, 51) is attached to the horizontal stabiliser (2) by means of supports (30) arranged in the direction of the chord of the primary fairing (50, 51), said supports (30) being located on the outside of said primary fairing (50, 51) relative to the
fuselage (1), the secondary fairing (80, 81); being arranged on the outside of the supports (30), said secondary fairing (80, 81) being responsible for covering the aforementioned supports (30) and ensuring good aerodynamic performance of the whole. The invention also relates to a method for installing a fairing system on the horizontal stabiliser (2) of an aircraft.
