Check to insure the fuel selector is on the proper (fullest) tank and that the seat backs are erect. The
seat belts and shoulder harness should be fastened and the inertia reel checked.
Turn "ON" the electric fuel pump and turn "OFF" the air conditioner. The mixture should be sel in
the full "RICH" position.
When on final approach, the airplane should be trimmed to an approach speed of about 76 MPH lAS
(66 KTS lAS) with flaps extended. The flaps can be lowered at speeds up to 115 MPH lAS (100 KTS lAS).
if desired.
The mixture control should be kept in full "RICH" position to insure maximum acceleration if it
should be necessary to open the throttle again. Carburetor heat should not be applied unless there is an
indication of carburetor icing. since the use of carburetor heat causes a reduction in power which may be
critical in case of a go-around. Full throttle operation with carburetor heat on is likely to cause detonation.
The amount of flap used during landings and the speed of the aircraft at contact with the runway
should be varied according to the landing surface and conditions of wind and airplane loading. It is
generally good practice to contact the ground at the minimum possible safe speed consistent with existing
conditions.
Normally, the best technique for short and slow landings is to use full flap and enough power to
maintain the desired airspeed and approach flight path. Mixture should be full "RICH," fuel on the fullest
tank, and electric fuel pump ""ON:" Reduce the speed during the flareout and contact the ground close to
the stalling speed. After ground contact hold the nose wheel off as long as possible. As the airplane slows
down, gently lower the nose and apply the brakes. Braking is most effective when flaps are raised and back
pressure is applied to the control wheel. putting most of the aircraft weight on the main wheels. In high
wind conditions, particularly in strong crosswinds, it may be desirable to approach the ground at higher
than normal speeds with partial or no flaps.
4.31 STOPPING ENGINE
At the pilot's discretion. the flaps should be raised and the electric fuel pump turned "OFF." The air
conditioner and radios should be turned "OFF," and the engine stopped by disengaging the mixture control
lock and pulling the mixture control back to idle cut-off. The throttle should be left full aft to avoid engine
vibration while stopping. Then the magneto and master switches must be turned "OFF."
