Image Number 4 for United States Patent #8083176.
A method to mount an aircraft engine on a rigid structure of an engine mount, includes securing, on the structure, an attachment body for an engine attachment, the attachment body configured to lie against a contact surface of the rigid structure oriented forwardly, and secured to the structure by at least one shear pin passing through a first and a second primary orifice. The securing of the body includes: pre-positioning the engine relative to the engine mount to place the first orifice opposite the second orifice, and inserting a pin fitted with a convex centering head through the two orifices, so that the pin forms the shear pin.
