A lightweight engine mounting assembly for attaching an engine to the wing of an airplane includes an outboard beam, an inboard beam, a forward annular stabilizing member and upper and lower, rear stabilizing members. Rearward extensions of the inboard and outboard beams have upper portions that extend rearwardly over the upper airfoil surface of a wing and lower portions that extend rearwardly and under the lower surface of the wing. The rearward extensions of the inboard and outboard beams are attached to the front main spar and to the upper and lower skins of the wing at the location of the wing ribs. The engine mount has a lower opening, bounded by the lower portion of the forward stabilizing member, the lower edges of the beams, and the lower, rear stabilizing member, and an upper opening bounded by the upper portion of the forward stabilizing member, the upper edges of the beams, and the upper, rear stabilizing member. Suitably shaped, removable cowl sections are located in the upper and lower openings. An annular air inlet ring is attached to and extends forwardly from the forward annular stabilizing member. A panel having an inverted, substantially U-shaped, transverse cross-section extends rearwardly from the upper portion of the rearward stabilizing ring to form the upper portion of an exhaust nozzle for a jet propulsion engine. The beams of the engine mounting assembly are constructed from appropriately shaped, longitudinally extending box beams interconnected by transversely extending rib members. The box beams and the rib members are covered on both the inner and outer sides with honeycomb panels. The stabilizing members are constructed from suitably shaped box beams.
