FIELD: transport.
SUBSTANCE: invention relates to aircraft engineering, namely to aircraft engine attachment post design. Rigid structure 8 of post 4 of aircraft engine attachment 6 represents a torsion box closed on lateral sides by first 34a and second 34b side panels. Said panels are jointed together by spaced apart (X) rigid crosswise ribs 36 that form multiple inter-ribs compartments(38, 381-388). Each of said compartments is restricted by two consecutive crosswise ribs 36. Note that side panels (34a, 34b) have holes (421-428). These holes allow access inside said torsion box. Note also that every inter-ribs compartment (381-388) of group (40) from any three of subsequent compartments have single access hole (421-428) made in side panels (34a, 34b). Note that said holes (421-428) are arranged alternating on first and second side panels (34a, 34b).
EFFECT: increased mechanical strength and reduced weight.
