71-20-00 ENGINE MOUNT
Description
The engine is mounted on the airframe via the engine mount.
The engine mount is constructed of welded steel tubes and is
bolted to the firewall at 4 attachment points. The tubes of the
engine mount structure are provided with an internal anti
corrosion treatment. The engine mount itself carries the oil
cooler and is used as a support for various hoses of the oil
system as well as electrical wiring.
The engine is nested into the engine mount on a system of
rubber shock mounts, each of which comprises two rubber
elements and one tubular spacer (ref. figure 3). The shock
mounts reduce the transmission of engine vibrations to the
airframe.
