Abstract

The invention relates to a rotary wing aircraft comprising an upper primary skin (2c) that separates an aircraft interior region from an aircraft upper deck (6). The aircraft upper deck (6) comprises engine compartments (20a, 20b), a tail rotor drive shaft (12c) arranged therebetween, a firewall arrangement (10b, 10c, 10d), and a central bracket (33) that is rigidly attached to the upper primary skin (2c) below the tail rotor drive shaft 12c. The central bracket (33) provides central bracket lugs (34a, 34b) in the engine compartments (20a, 20b) above the firewall (10d). The engine compartments (20a, 20b) comprise inboard fixations (19a, 19b) with inner main mounting brackets (16a, 16b) adapted for being rigidly attached to engines (11a, 11b) and to inboard lateral mounts (72a, 72b) that attach the inner main mounting bracket (16a, 16b) with the central bracket lugs (34a, 34b).
