Installation Instructions for Gulfstream I/II
Monorail Sunvisor System
(Kit RGI/II-300-1)
Doc: 9041-0178-001
This is an FAA STC’d installation requiring a logbook entry upon completion.
Please read through these instructions completely before beginning.
Installation Hardware (included):
8 AN526C832R9
#8-32 x 9/16 Screws
8 A8K75
#8 Rivnuts
1 3/32 Hex Key
1 7/64 Hex Key
4 Snap rings (e-clip)
The G-I/II unit is a three rail,
four visor combination since
the sliding window and
associated electrical
connections do not permit a
full wrap around rail as in the
This installation is straight
forward since each side rail
uses existing fasteners in the
trim above the window line.
Since Gulfstreams are
completed at various facilities
not all fastener locations will
be the same. Four additional
A8K75 rivnuts and
AN526C832R9 screw
fasteners are provided if
Install the side rails approximately ½ inch behind the window electrical connection. There should also
be approximately ½ inch clearance to the aft bulkhead. DO NOT DRILL INTO THE AIRCRAFT
STRUCTURE. Use existing fasteners or install using the A8K75 rivnuts and provided screws. The
rail should sit high enough so that no light comes over the rail.
The front visors are designed to provide maximum coverage without interfering with the pilot’s line of
sight. The lenses are profiled to fit the front windscreen when stowed and there is a stow shelf on the
center bracket to ensure the visors will not deploy during take off and landing.
To install the front visor system place the entire unit under the overhead panel with the visor units
stowed on the shelf. Each visor must be outboard enough to miss the compass but still sit on the
shelf. Move the entire unit forward until the visors touch the windscreen. Move back approximately
½ inch for clearance and mark the mounting bracket holes. Since the bottom of the overhead panel
is slanted, the closer the rail is to the front windscreen the more hidden it becomes.

If you are familiar with the aircraft the A8K75 rivnuts and AN526C832R9 machine screws can be
installed without dropping the bottom of the overhead panel. If you are not familiar with the
equipment located in the vicinity of and adjacent to the mounting holes drop the panel and check for
possible obstructions or interference. DO NOT DRILL INTO THE AIRCRAFT STRUCTURE.
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
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 slide 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, 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.
