Figure 605. Forward Crosstube Measurement
B. Forward Crosstube Inspection
(Ref. Figure 605)
The forward crosstube must be
replaced when there has been
permanent deformation to the point where
it is no longer safe to fly. The change in
spread between the skid tubes is the criteria
for replacement.
(1). Examine the forward crosstube for
cracks, dents, gouges, and corrosion.
(a). No cracks, dents, gouges, or corrosion
permitted.
(b). If installed, remove the side-stop
clamps (ref. Removal / Installation).
(c). Examine the mating surfaces of the
forward crosstube and side-stop
clamps for corrosion, nicks, and
scratches with a 10X magnification
glass.
1). If there is damage, remove the
landing gear assembly for inspec
tion and repair (ref. Repairs) or
replacement.
2). If there is no damage, install the
side-stop clamps (ref. Removal /
Installation).
(2). Examine the forward crosstube for
indications of contact with the fuselage
fittings or the front saddle assemblies.
(a). If there are indications of contact,
replace the forward crosstube.
(3). Examine the forward crosstube bolt
holes for damage, deformation, and
corrosion.
(a). No damage, deformation, or corrosion
is permitted.
(4). Jack the rotorcraft (ref. Section
07-10-00).
(5). Measure the spread of the forward
crosstube from the outside face of the
gusset flange on the left spacer to the
outside face of the gusset flange on the
right spacer.
(a). Record the measurement in the RLB.
(b). The nominal unloaded measurement
is 88.30 inch (224.28 cm).
(c). If the measurement is more than the
maximum spread (ref. Table 602),
replace the forward crosstube.
