Arrangement for coupling a coupling pivot for a trimmable horizontal stabiliser to the tail fuselage of an aircraft

Arrangement for coupling a coupling pivot for a trimmable horizontal stabilizer to the tail fuselage of an aircraft, in which the tail fuselage comprises at least one frame and one outer covering joined to the frame, which comprises

• an inner plate, with a first upper fastening hole, a first lower fastening hole and a first passage hole between the first upper fastening hole and the first lower fastening hole;
• an outer plate with a second upper fastening hole, a second lower fastening hole and a second passage hole between the second upper fastening hole and the second lower fastening hole;
• the first fastening holes respectively facing the second fastening holes and the first passage holes facing the second passage holes in order to permit the passage of a coupling pivot of the horizontal stabilizer;
• an upper coupling lug located between the upper fastening holes and a lower coupling lug located between the lower fastening holes, said lugs being respectively arranged above and below a cut-out provided for the horizontal stabilizer in the covering of the aircraft;
• the upper lug and the upper fastening holes forming an upper space traversed by a first securing element;
• and
• the lower lug and the lower fastening holes forming a lower space traversed by a second securing element;
• wherein
• the coupling lugs are integral with separate reinforced zones of the covering of the tail fuselage in respective neighboring areas of the cut-out and of the frame;
• the inner and outer plates between them clasp at least the respective reinforced zones in which the coupling lugs are provided.
