13.5 ENGINE MOUNT
13.5.1 DESCRIPTION
The engine mount is a welded assembly. Its purpose is to support the engine and attach the
engine to the airframe. The engine is attached to the mount with rubber cushions which absorb
engine vibrations.
Spacers are used to correctly align the engine. Ensure that they are correctly marked on removal
and correctly replaced on reassembly.
13.5.2 ENGINE MOUNT REMOVAL
Remove the engine in accordance with the instructions given in the engine Instruction &
Maintenance manual.
Cut the zip-ties holding wires, vents and lines to the engine mount.
In some cases the instrument panel covers the bolts for the engine mount. Access must be
secured to these bolts
– either from the inside of the panel or by removing or loosening the
instrument panel mounting.
Un-bolt the engine mount fasteners and remove the mount from the aircraft.
13.5.3 ENGINE MOUNT INSPECTION
Visually inspect for cracks, dents, bends and corrosion. Mild corrosion can be treated by
sanding, applying etch primer then painting. Engine mounts with severe corrosion must be
replaced.
If cracks, dents or bends are found refer to Jabiru Aircraft or our local authorised agent. In most
cases the damaged mount must be replaced.
WARNING
The engine mounts should not be repaired. If damaged, replace with a new part.
