Post-Paint>Fuselage>Assemble instrument panel
Objectives of this task:
To fit all instruments into the instrument panel, fit all of the electrical wiring and terminate to
multi-pin connectors ready for installation into the instrument panel housing.
There are 5 panel options as well as builder variations and so this task will address the fitting
of hardware and both analogue and digital instrumentation in general terms and will use
photos of Standard (analogue) and Jumbo (digital) panels to illustrate various aspects of the
task. Refer also to the
Post-Paint>Fuselage>Electrical wiring diagrams task.
Fitting of the hardware and instrumentation to the panel is not particularly difficult but the
actual wiring is a task that requires
considerable care and attention to detail.
A kit builder can do the wiring provided that he or she is careful and methodical. If you are
not experienced at electrical wiring and the reading of electrical wining diagrams then you
may wish to consider having the wiring of the panel done by a specialist technician, or
possibly a friend or acquaintance may have the necessary skills.
Materials and tools required:

Card #16 “
Electric Flaps
” specifically the flap actuating switch and flap switch handle
Wire stripping and crimping tools
Prepare the work area
You will need a clean well lit workbench and a piece of foam about the same size as the panel
so that the panel can be placed face down without any risk of scratches to the front face of the
panel or the faces of the instruments.
All electrical connectors should be close at hand and your heat gun will be needed to shrink
the coloured tags onto the wiring. All tools should be within easy reach.
There will be a lot of packing waste so empty your rubbish bin before starting.
Unpack the hardware and fittings
Strip all of the hardware and fittings from the Cards – use a knife to cut around each item and
then peel the plastic shrink-wrap back and away from the item. Be very careful when cutting
the noise suppression filter out of the wrap: do not cut near or through the wires.
Sort all of the items into groups: switches, circuit breakers, wiring, lights, etc.
Empty the bag of electrical connectors onto your bench top and sort the items into groups:
note that the red female spade connectors are for single wires and the blue ones are for 2
wires. Do the same with the screws and fittings bag: select the black screws (2 lengths) and
nuts, the silver screws and Nyloc nuts (M3 and M4) and the gold anodised captive nuts. The
remaining items should be put aside for later use when installing the panel into the aircraft.
The M3 silver screws and Nyloc nuts will be used for busbar to circuit breaker connections,
the M4 silver screws and Nyloc nuts will be used to fix hardware to the panel, while the black
screws will be used to mount instruments to the panel. The gold anodized captive nuts will be
clipped into the analogue instruments as each instrument is being fitted.
On factory built aircraft we sandblast and paint the heads of the M4 silver screws satin black
so that they blend into the panel. You may wish to do the same before assembling your panel.
