LANDINGGEAR OPERATION
CAUTION Under
no
circumstances should the landing
gear be operated
electrically while the
handcrank
is engaged.
In the
event
of such
an
operation,
a
teardown and
magnetic inspection
should be
performed
for damage
to
engagement
slot in
worm
shaft.
NOTE
Since the battery
voltage
is
not
sufficient
to
properly cycle the landing
gear
for this inspection,
use
only
an
external power
source
capable
of delivering
and
maintaining 28.25 0.25
VDC, to
the airplane's
electrical
system throughout the
extension and retraction
cycles when
performing
the landing
gear retraction
inspection. For
more
specific
information which may be necessary to
accomplish the
following items,
refer
to
Chapter
32-30-00 in this Maintenance Manual.
1.
LANDING
GEARACTUATOR
ASSEMBLY With the
airplane
on
jacks and
the retraction
cycle
started enough to
break the downlock
tension, apply
a
sharp load by
hand in
an
aft direction
against
the
nose gear
strut.
If this
causes
the main gear wheels
to
move
approximately
1/2
to
1
inch, it is
a
good
indication that
the gear actuator
assembly
needs overhaul and/or
adjustment.
