tended
spins
of two
to three turns or more, the spin will tend to change into
a
spiral,
particularly
to the right. This
will
be accompanied
by
an
incroase
in airspeed and
gravity
loads
on the
airplane.
If this oocurs, recovery
should be accomplished
quickly
by
leveling the
wings
and recovering
from
the resulting
dive.
Regardless of how
many turns the spin is held or how
it
is entered,
the
following
recovery
technique
should be used:
1. VER,IFY THAT
TFIROTTLE IS IN IDLE POSITION
AND AILER.
ONS ARE NEUTF,AL.
2. APPLY
AND HOLDFULL
R,UDDER, OPPOSITE
TO THE

NOTE
If
disorientation
precludes
a visual
determination
of
the
direction
of rotation,
the symbolic
airplane in the turn
coordinator
may be referred
to for this information.
Variations
in basic airplane rigging or in weight
and
balance
due
to
installed eguipment
or right seat occupancy can cause differences
in
behavior,
particularly
in
extended spins. These
differences are normal
and
will result in
variations in the spin characteristics and in the spiraling
tendencies
for
spins of more thanÞ turns. However, the recovery
technique
should always
be used
and
will result
in
the
most expeditious
recovery
from any
spin.
Intentional spins
with
flaps extended are
prohibited,
since the high
speeds
which
may occur during recovery
are
potentially
damaging
to the
flap/wing structure.

surface
winds and airturbulence
