1. An engine support truss assembly for aircraft, the engine support truss assembly comprising:
a mounting plate having a front side and a back side opposite the front side;
a truss structure mechanically coupled to the front side of the mounting plate, wherein the truss structure comprises a plurality of structural members each comprising precipitation-hardened stainless steel;
a backup structure mechanically coupled to the back side of the mounting plate, wherein the backup structure is configured to provide mechanical support to the truss structure;
a machined collar mechanically coupled to the truss structure opposite the mounting plate, wherein the machined collar comprises a first side facing the mounting plate and an outer edge;
a flange fastened to the outer edge of the machined collar, wherein the flange comprises a bend such that a portion of the flange extends partially over the first side of the machined collar;
a slip plane comprising a gap formed between the portion of the flange and the first side of the machined collar, wherein the slip plane is configured to allow adjustment of a thrust angle of an engine; and
a pre-defined shim configured for sliding into the gap after the thrust angle of the engine has been adjusted.
