Abstract
In order to bring the primary structure of an engine mounting pylon of an aircraft as close as possible to a wing box: an aircraft wing includes a wing box made partly by a front spar and an intermediate spar; a mounting pylon including a primary structure in the form of a box having transverse reinforcement ribs; and attachment means for attaching the primary structure of the mounting pylon on the wing box. These attachment means include a row of bolts along which each bolt passes through a structural part of the pylon on one hand, and on the other hand a fitting attached to one of the front and intermediate spars.
