During installation of your new monorail sun visor system,
we will refer to the attach brackets as Brackets #1 through
#7 as diagrammed here:
These brackets pick up the three (3) existing #8 fasteners
on either side of the aircraft above the window line. The
side brackets are slotted to allow for manufacturing
variance on the location of the shock mounts to which the
overhead shell attaches.
Carefully take the monorail into the cockpit. The ends can
be sprung inward slightly to get it into the cockpit area.
Remove the three (3) existing #8 fasteners and the finishing washers on the pilot’s side and loosely
attach one (1) AN526C832R24 (#8-32 x 1-1/2 screw) in brackets #1 and #7, and one (1)
AN526C832R10 (#8-32 x 5/8 screw) in brackets #2, #3, #5 and #6. Your headliner fasteners attach
to shock mounts and on older aircraft these may be loose or difficult to tighten. At your option,
replace any defective shock mounts or use A8K75 rivnuts to give a good anchor to the headliner for
the fasteners. The slotted brackets are wide enough so that the rivnut can be placed on the same
plane as the original fastener yet not be in the way. The simplest and fastest method of installation of
course, is to use the existing shock mounts.
Prior to installing any A8K75 rivnuts, attach copilot’s brackets to shock mounts in the same manner.
The monorail may need to be shifted slightly as every Falcon 20 is not identical in hole location, yet
the monorail should provide for these mounting differences.
With all six (6), or as many of the side fasteners possible installed, mark the location of bracket #4 as
it sits tight against the front overhead cross panel. This mark will be used to locate the hole for the
installation of the A10K80 rivnut. Check that the forward part of the monorail does not hit the
overhead. Bracket #4 should provide adequate clearance for the visor clamping block and mounts
directly forward of the compass.
At this point, if the installations of any rivnuts are required for the side brackets, mark their locations.
Open pilot’s sliding widow and check for adequate clearance.

Remove the monorail and drill rivnut holes as required into the fiberglass shell. If covered with fabric,
consider punching the fabric so that it does not bind up and twist with the drill bit. DO NOT DRILL
The monorail may be shimmed to allow additional clearance for window opening.
Reinstall the monorail, securing all fasteners.
Install both visor assemblies by unscrewing the thumb tension knobs until the clamping blocks can be
slipped over the rails. Tighten the thumb tension knobs until the snap ring can be installed onto the
snap ring groove on the back. Install the provided snap ring. This snap ring prevents inadvertent
over-loosening of the tensioning knob, and acts as a tactile indicator that further loosening must not
be attempted.
When the visor is on the rail, the tensioning knob should face the pilots.
Check for proper clearance between the visor thumb knob and the headliner by tightening the thumb
knob and rotating the visor to the overhead on the side of the aircraft where it would be stowed. The
thumb knob should not hit the headliner. If this is the case use the shims mentioned above.
To move the visors, loosen the thumb tensioning knob until the clamp is loose enough to be slid along
the monorail while holding the thumb knob. To move past the mounting brackets, the visor must be
positioned so that the clamps will pass over the
Your monorail system is equipped with a swivel
design that allows rotation about the axis of the
lens. Rotational tension can be adjusted by
adjusting one or both of the hex socket head cap
screws located on the back side of the clamp block
and below the thumb knob screw.
The visor should be aligned with the clamp block
before sliding along the monorail.
As this is a one piece monorail system, either visor can move the entire length of the rail, allowing
complete sun shielding not previously available.
Continued Airworthiness Instructions:
(On the ground only)
Periodically clean the lenses with a soft cloth, mild soap and water or an approved
aviation grade windscreen cleaner. Do not use abrasives on the lens.
Periodically adjust the pivot tensions on the visor assemblies.

Airworthiness Limitations:
The Airworthiness Limitations Section is FAA approved and specifies maintenance required under
§§43.16 and 91.403 of the Federal Aviation Regulations unless an alternative program has been FAA
approved. There are no airworthiness limitations associated with this installation.
