The engine mount is composed of a framework of steel tubes welded together, with four attachments for the power plant and four mounting plates for attachment to the firewall.
The engine mount is secured to the firewall by means of sixteen bolts (five per upper mounting plate, three per lower mounting plate), and supports the power plant by means of four attachment fittings equipped with silent-blocks.

The silent-blocks located at the power plant attachments on the engine mount are designed to absorb the engine vibrations and to reduce to a minimum their spreading to the airframe thanks to the rubber vibration absorbers.
