The LIVE
®
suspension system is engineered for on condition maintenance, with easy
access to all components for inspections or any necessary actions. All of the components
within the system are sized to limit stress, and have been carefully designed to be
field replaceable, without removing the transmission. Static loading (when the helicopter
is parked) of the pylons and isolation mounts is minimal to insure long in-service life.
The system is accessible by decowling and through a removable panel in the interior
cabin roof.

Two "spike" and "up-stop" assemblies are located on the isolation mount fittings on
either side of the transmissions' base. The spikes extend into the upper fuselage through
aluminum alloy rings ("striker plates") mounted to the left / right main roof beams with
low-shear rivets. Any transmission motion outside specified limits will mark the interior
of the rings, or shear the rivets, indicating the need for system inspection. The bottom
of the spikes are attached to stop fittings which provide two additional redundant load
paths for transmission retention.
