15.4 INSTRUMENTS
15.4.1 DESCRIPTION
Jabiru Aircraft are equipped with a wide range of instruments depending on specification. Generally,
all instruments are secured to the panel fascia with screws inserted through the panel face.
In some cases rack mounts are used where the instrument is held in a rack which, in turn, is secured
to the fascia or to the fibreglass panel mount.
15.4.2 INSTRUMENT REMOVAL & INSTALLATION
To remove an instrument, disconnect wiring or pluming to the instrument, remove instrument
mounting screws and take instrument out from behind, or in some cases, from the front of the panel.
In some cases, due to access, it may be easier to partially remove the panel fascia as noted above
before attempting to remove instruments.
For instruments mounted in a
rack refer to the instrument manufacturer’s instructions for removal and
installation procedures.
In all cases when an instrument is removed, disconnected lines or wires should be protected. Cap
open lines and cover pressure connections on instrument to prevent thread damage and entrance of
foreign matter. Wire terminals should be insulated or tied up so that accidental ground or short-
circuiting will not occur.
Generally, the installation procedure is the reverse of the removal procedure. Ensure mounting
screws and nuts are tightened firmly, but do not over-tighten, particularly on instruments having
plastic cases. The same rule applies to connecting plumbing and wiring.
