G. Roof Beam Installations
The major components contained within each
roof beam installation are the vertical and
horizontal webs, roof beam and handhold
support ribs, extrusion angle, aft deck angle,
track pockets, forward and aft outer roof beam
skins, and rear stay deck fitting assembly.
Secondary components include cowl support
clips and doublers, door track brackets and
cleats, and roof beam attachment cleats,
doublers, splice components, and standard
hardware.
Vertical and Horizontal Webs
−
The vertical
and horizontal web components are primary
structural components that when combined
with the roof beam outer skins form the
triangular shaped roof beam. The vertical and
horizontal webs are fabricated from aluminum
alloy sheet.
Roof Beam and Handhold Support Ribs
−
The
roof beam and handhold support ribs are
secondary structural components that provide
attachment for the vertical and horizontal
webs, and the outer roof beam skins.
The roof beam and handhold support ribs are
installed internal to the triangular shaped
sub-structure formed by the vertical webs,
horizontal webs, and the outer skins.
The handhold support ribs are installed at FS
160.63, 167.60, 218.50, and 225.47. Roof beam
support ribs are installed at FS 188.00,
197.66, 207.36, 230.50, and 249.78. The roof
beam and handhold support ribs are fabri
cated from aluminum alloy sheet.
Extrusion Angle
−
The extrusion angle is a
primary structural component that is installed
between the vertical and horizontal web
components. The extrusion angle extends
from the FS 155.5 frame to FS 225,0. The
extrusion angle is machined from aluminum
alloy extrusion.
Aft Deck Angle
−
The aft deck angle is a
primary structural component that functions
as the attachment angle between the respec
tive engine deck, aft outer, and aft deck skins,
and the rear fuselage shell assembly. The aft
deck angle is fabricated from aluminum alloy
sheet.
Track Pockets
−
The track pockets are
secondary structural components that form
evironmental closeouts at the cutouts in the
forward outer skin for the upper cabin door
track.
The track pockets are composite components
that are fabricated as monolithic laminates.
Each track pocket is fabricated using multiple
plies of graphite/epoxy and fiberglass/epoxy.
The doublers are fabricated from aluminum
alloy sheet.
Forward and Aft Outer Roof Beam Skins
−
The
roof beam forward and aft outer skins are
primary structural components that when
combined with the roof beam vertical and
horizontal web components form the triangu
lar shaped beam.
The forward roof beam skin is installed from
the 155.50 frame and terminates immediately
forward of the FS 230.50 frame. The aft roof
beam skin is installed from the aft end of the
forward skin to FS 268.00. The roof beam
forward and aft outer skins are fabricated
from aluminum alloy sheet.
Rear Stay Deck Fitting Assembly
−
The rear
stay deck fitting assembly is a primary
structural component that provides for
attachment of the rear stay assembly for the
left or right engine.
The rear stay deck fitting assembly consists of
a fitting and a flanged bushing. The fitting is
machined from titanium alloy stock. The
flanged bushing is a standard corrosion
resistant steel component. The bushing is
press fit installed into the fitting, and then
reamed to the final hole dimension.
Secondary Components
−
The secondary
components include cowl support clips and
doublers, door track brackets and cleats, roof
beam attachment cleats, doublers, and web
splice components are secondary structural
components. These components are fabricated
from aluminum alloy sheet.
