Configuration Effects
NOTE
Intentional spins in other than cruise configuration at idle power are
prohibited.
The effect of power on the erect spin appears to flatten the pitch attitude. At
maximum power, the nose rises well above the horizon at the completion of the
first spin turn.
Reducing power to IDLE causes a noticeable nose-down pitch with the spin
stabilizing as previously described for erect, idle power spins. Due to engine torque
effects, right power-on spins take longer to develop, regardless of aircraft
configuration, than spins performed to the left.
Applying left aileron at the stall will generally prevent the aircraft from entering a
right power-on spin, resulting in a spiral for as long as full power is maintained.
One turn incipient spins have been performed in power-off and power-on
configurations with the speed brake extended.
The speed brake position had no noticeable effect on spin or spin recovery
characteristics during these spins.
SPIN RECOVERY
CAUTION
During spin recovery, pitch control inputs well forward of neutral may result
in a loss of oil pressure and engine damage.
Erect Spin Recovery
Erect spin recovery is prompt after recovery controls are applied. In all cases, as
the control stick is moved forward and rudder is applied opposite to the direction of
turn needle deflection, the pitch attitude will steepen and spin rate will initially
increase.
Approximately 50 pounds of push force will be required to move the control stick
well forward of the neutral position.
Spin rotation will abruptly cease with the aircraft in a steep nose-down attitude
within one and one-half turns after applying controls. Controls should be
neutralized and a smooth pull-out initiated to stop the loss of altitude and prevent
airspeed from building excessively.
