13. CONDITION levers – FUEL CUTOFF.
14. FIRE PULL handles – Pull.
15. MASTER SWITCH – OFF.
h. Landing With Flat Tire(s). If aware that a
main gear tire(s) is flat, a landing close to the edge of
the runway opposite the flat tire will help avoid veering
off the runway. If the nose wheel tire is flat, use
minimum braking.
9-31. LANDING WITH INOPERATIVE WING FLAPS
(UP).
The aircraft does not exhibit any unusual
characteristics when landing with the wings flaps up.
The approach angle will be shallow and the touchdown
speed will be higher resulting in a longer landing roll.
9-32. CRACKED WINDSHIELD.
a. External Crack.
crack is noted, no action is required in flight.
NOTE
Heating elements may be inoperative in
areas of crack.
b. Internal Crack. If an internal crack occurs,
perform the following procedure.
1. Descend – Below 25,000 feet.
2. Cabin Pressure

10 minutes.
9-33. CRACKED CABIN WINDOW.
If crack(s) in a cabin window ply(s) occurs,
perform the following procedure.
1. Crew oxygen masks – 100% and on, if
above 10,000 feet.
2. CABIN SIGNS switch – BOTH.
3. Passenger oxygen – ON and checked, if
above 10,000 feet.

The copilot should
confirm that all passengers have oxygen
masks on and are receiving supplemental
oxygen if required.
4. Cabin pressure – Depressurize.
5. Land as soon as practicable. If both plys
of a cabin window have developed cracks,
the aircraft shall not be flown, once
landed, without
authorization.
NOTE
Treat outer ply cracks which are linear, not
circular, or cracks that touch the frame as
an inner ply crack.
9-34. DITCHING.
If a decision to ditch is made, immediately alert
all personnel to prepare for ditching.
approach into the wind, if the wind is high and the seas
are heavy. If the swells are heavy but the wind is light,
land parallel to the swells. Set up a minimum rate
descent (power on or off, as the situation dictates
airspeed 110 to 120 KIAS). Do not try to flare as in a
normal landing, as it is very difficult to judge altitude
over water, particularly in a slick sea. Leveling off too
high may cause a nose low "drop in," while having the
tail too low in impact may result in the aircraft pitching
forward and "digging in."
impact shock and several skips before the final hard
shock. There may be nothing but spray visible for
several seconds while the aircraft is decelerating. To
prevent cartwheeling, it is important that the wings be
level when the aircraft hits the water. After the aircraft
is at rest, supervise evacuation of passengers and exit
the aircraft as quickly as possible.
ditching, the life raft and first-aid kits should be
secured close to the cabin emergency hatch for easy
access when evacuating; however, do not remove the
raft from its carrying case inside the aircraft.
exiting the aircraft, keep the raft from any damaged
surfaces that might tear or puncture the fabric. The
length of time that the aircraft will float depends on the
fuel level and the extent of aircraft damage caused by
the ditching. Figure 9-3 illustrates the appropriate body
positions for ditching, Figure 9-4 shows wind swell
information, and Table 9-1 lists the appropriate duties
for crew and occupants for planned and immediate
ditchings. Perform the following procedures:
