PANEL SUPPORT INSTALLATION AND
EMERGENCY LOWERING DEVICE
INSTALLATION
The panel support and emergency lowering device
installation (fig. 5-13) consists of the panel support
stanchions, panel supports, and an emergency lowering
device. Panel support stanchions are to be used anytime
panel supports are being installed or removed. The
panel support stanchions are positioned between the
raised JBD panel and lip of the flight deck. The panel
support stanchion is designed to support the weight of a
pair of fully raised JBD panels; however, the stanchion
will not prevent the lowering of JBDs under pressure.
To provide a total margin of safety, panel supports
must be property installed prior to any maintenance
