The
purpose
of
this
Service
Bulletin
is
to
replace
the
fuel
nozzle
supply
manifold
assemblies
(FS
manifolds)
(FS01
thru
FS08)
and
install
new
brackets
and
clamps
on
the
FS
manifolds.
This
change
adds
suf
ficient
dampening
to
shift
the
natural
frequency
outside
of
the
acoustic
frequency
range
identified
during
an
engine
investigation.

in
this

After
initial
engine

but
before
final
delivery
,
P&W
may
change
part(s)
in
the
engine
or

PW4ENG

Partial
incorporation
while
engine
is
installed
on
aircraft
is
permissible
and
considered
partial
terminating
action.
N
O
T
E
:
During
partial
incorporation,
make
sure
to
completely
install
all
brackets
and
hardware
for
each
FS
manifold.

1.
Problem:
On
three
separate
occasions
cracks
were
discovered
on
the
FS
manifolds.
2.
Cause:
The
cracking
was
caused
by
high
vibration
stresses
observed
due
to
the
acoustic
combustor
mode
and
the
FS
manifold
structural
mode
coupling.
3.
Solution:
New
brackets
and
clamps
are
installed
to
reduce
the
stresses
and
the
FS
manifolds
will
be
dampened
to
shift
the
natural
frequency
outside
the
acoustic
frequency
range.
