(4) Approach at 95 MPH with the wing flaps full down.
(5) All switches (except rear-engine ignition) -- Off.
(6) Touchdown in a level attitude for minimum damage.
(7) Mixtures -- Idle cut-off (ICO").
(8) Rear-Engine Ignition/Starter Switch -- "OFF."
(9) Turn fuel selectors to "FUEL OFF."
FORCED LANDING (Precautionary Landing With Power),
Drag over selected field with flaps "1/3" and 100 MPH airspeed,
noting type of terrain and obstructions.
(2) If surface is smooth and hard, plan a wheels-down landing using
full flaps and keeping the nose wheel off ground as long as practical.
(3) If surface is rough or soft, plan a wheels-up landing as follows:
a. Approach with flaps down at 90 MPH.
b. Turn off aU switches except ignition switches.
c. Unlatch cabin door prior to flare-out.
d. Reduce power to a minimum during flare-out.
e. Prior to contact turn ignition switches "OFF. "
f. Land in a slightly tail-low attitude.
g. Attempt to hold the tail low throughout slide,
FORCED LANDING (Complete Power Loss),
In the event both engines are out, maximum gliding distance can
be
obtained by maintaining indicated airspeeds (with the landing gear and
wing flaps retracted and propellers feathered) as shown in the Maximum
Glide Diagram, figure 3-3.
(1) Pull mixture control levers to idle cut-off.
(2) Turn both fuel selector valve handles to "FUEL OFF."
(3) Turn off all switches except master switch.
(4) Glide at 115 MPH.
(5) If field is smooth and hard, extend landing gear within gliding
distance of field (manual extension requires approximately 85 full
strokes of the emergency hand pump).
(6) Approach at 95 MPH with the wing flaps full down.
(7) Turn off master switch.
(8) Make a normal landing, keeping nose wheel off ground as long
as practical.
(9) If terrain is rough or soft, plan a wheels-up landing as follows~
a. Approach at 95 MPH with flaps full down.
b. Turn off master switch.
c. Unlatch cabin door prior to flare-out.
d. Land in a slightly tail-low attitude.
e. Attempt to hold tail low throughout slide,
ELECTRICAL SYSTEM - EMERGENCY OPERATION.
The following corrective action should be taken when electrical sys­
tem malfunctions occur.
Red "VOLTS HIGH" light comes on:
(1) Turn off both alternators. ("VOLTS HIGH" light will go out.)
(2) Switch to alternate regulator.
(3) Turn on alternators one at a time. ("VOLTS HIGH" light should
remain out. )
(4) If "VOLTS HIGH" light illuminates again, turn off both alterna­
tors. Turn off all non-essential electrical equipment and terminate
flight as soon as practical.
Amber "BAT DIS" light comes on:
The amber "BAT DIS" light does not necessarily indicate a malfunc­
tion. Its main function is to indicate current being drawn from the bat­
tery.
(1) Check HALT NOT CHARGING" light for an indication. If there
is no indication, or if only one light is on, reduce electrical load
until "BAT DIS" light goes out.
NOTE
If both "ALT NOT CHARGING" lights are on, turn
off aU non-essential electrical equipment and ter­
minate flight as soon as possible.
