There have been several factory sunvisor
installations in the 400 series aircraft and although
they are basically all the same, the exact location
of their mounting positions has been different. To
install your new Rosen Sunvisor System you will
either fasten the front mounting brackets directly to the nut plates used for the plastic clips from the
original visor OR you will use the rivnuts provided. To determine which fastening method you will
use, please note the clip location diagram below.
If the aircraft you are installing the visor system
into has the original clip in position ‘A’ skip to
Instruction A.
If the clip is in position ‘B’ you will need to use
the four (4) A8K75 rivnuts and the four (4)
AN526C832R10 (#8-32 x 5/8) Screws provided to fasten the front mounts to the overhead. The only
difference in using the rivnuts to fasten the front brackets is that instead of having the rail positioning
predetermined, you must locate its position to
insure the correct location of the rivnuts. The
monorail must be far enough forward so the
standoffs on each corner hold the rail off the
Royalite overhead trim. By ‘hooking’ the rear
bracket over the trim at the rear of the cockpit on
both sided the monorail can be slid fore and aft to locate the correct position for the front mounts.
Remove the existing sun visors at the mounting pivot. If you remove the visor retaining clips replace
the screws in order to retain the added rigidity to the Royalite trim.

After centering the monorail and getting the correct forward position mark
the Royalite trim for the rivnut installation which will secure the front of the
monorail. Each forward bracket has a 1.40 inch slot. The Rivnut
placement should be ~.40 inch in from each side of the slot.
Drill 4 holes for the rivnut installation in the Royalite only. Do Not Drill Into
The Aircraft Structure. Carefully install the rivnuts into the Royalite. Do not over compress the
rivnut as excess stress on the Royalite can cause it to fracture.
Using the AN526C832R10 screws provided, fasten the monorail front brackets to the rivnuts just
Proceed to Instruction ‘B’.
Instruction A
Remove the present visors by unscrewing the two (2) #10 fasteners which secure the ball joint cover
on both sides of the aircraft. Remove the visor plastic clips from the overhead.
Install the monorail by ‘hooking’ the rear brackets over the trim to support the back of the monorail
and fasten the front brackets to the nut plates that held the plastic clips using the AN526C832R16
(#8-32 x 1) screws and AN960D9 aluminium washers provided. The front brackets have been made
wide enough that they should accommodate the variations in spacing found with the original plastic
clip mounting. If this is the case it is acceptable to mount the front brackets with just one fastener per
mounting bracket. (Two screws were used to prevent the clip from rotating. If only one fastener is
used, and the remaining screw hole is visible beside the bracket, fill it with the second fastener.
Proceed to Instruction ‘B’.
Instruction B
Hold the rear bracket slightly above the Royalite trim line and
mark the center position of the tapped mounting hole. The
Royalite will be sandwiched between the aft pressure plate
and the threaded rear bracket. Mark both sides approximately
3/8 of an inch from the top of the Royalite.
Reposition the monorail to allow clearance to drill a 3/16
diameter hole in the Royalite. Do Not Drill Into The Aircraft
Replace the end bracket over the Royalite Trim aligning the
tapped hole with the hole in the trim. Use the Aft Pressure Plate to sandwich the Royalite and secure
with the AN526C832R5 (#8-32X5/16) fasteners. Apply a small amount of Loctite to these rear
Monorail installation is now complete.

Installing the visor assemblies
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 e-clip. This e-clip prevents inadvertent over
loosening of the tensioning knob and acts as a tactile indicator that further loosening must not be
When the visor is on the rail the tensioning knob should face the pilots.
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 the clamps pass over the brackets.
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 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.
Continued Airworthiness Instructions:
(On the ground only)
Periodically clean the lenses with a soft cloth and Rosen Cleaner, Polisher and
Protectant or mild soap and water. Do not use abrasives on the lens.
Periodically adjust the pivot tensions on the visor assemblies.
Periodically clean rail.
