Unbalanced mass effects can occur at the low pressure compressor ( 5 ) of an aircraft engine. Stiffeners ( 20 ) are proposed to increase the stiffness of the assembly and therefore reduce possible cracks due to accidental unbalanced masses, one end ( 22 ) of the stiffener can be fixed to the engine casing ( 7 ) at the structural arm ( 10 ), and the other end ( 32 ) can be fixed to the compressor ( 5 ), preferably at the upstream face of the third guide vane (RD 3 ). Advantageously, the stiffeners ( 20 ) are made of two parts fixed to each other; their manufacturing is optimized to limit the additional weight due to their presence.
