9-4. AFTER EMERGENCY ACTION.
This section describes the aircraft systems emer-
gencies that may reasonably be expected to occur
and presents the procedures to be followed. Emer-
gency procedures are given in checklist form when
applicable. A condensed version of these procedures
is in the Operators and Crewmembers Checklist,
TM 55-1510-221-CL. Emergency operations of avi-
onics equipment are covered when appropriate in
Chapter 3, Avionics, and are repeated in this section
only as safety of flight is affected.
After a malfunction has occurred, appropriate
emergency actions have been taken, and the aircraft
is on the ground, an entry shall be made in the
remarks section of DA Form 2408-13 describing the
9-5. EMERGENCY EXITS AND EQUIPMENT.
Emergency exits and equipment are shown in
9-6. EMERGENCY ENTRANCE.
Immediate action emergency items are under-
lined for your reference and shall be committed to
memory. During an emergency, the checklist will be
called for to verify the memory steps performed and
to assist in completing any additional emergency
Entry may be made through the cabin emer-
gency hatch. The hatch may be released by pulling
on its flush-mounted pull-out handle, placarded
EMERGENCY EXIT - PULL HANDLE TO
RELEASE. The hatch is of the nonhinged plug type
which removes completely from the frame when the
latches are released. After the latches are released,
the hatch may be pushed in.
9-7. ENGINE MALFUNCTION.
The urgency of certain emergencies
requires immediate action by the pilot.
The most important single consideration
is aircraft control. All procedures are sub-
ordinate to this requirement. Reset MAS-
TER CAUTION after each malfunction
to allow systems to respond to subsequent
9-3. DEFINITION OF LANDING TERMS.
The term LANDING IMMEDIATELY is
defined as executing a landing without delay. (The
primary consideration is to assure the survival of
occupants.) The term LAND AS SOON AS POSSI-
BLE is defined as executing a landing at the nearest
suitable landing area without delay. The term
LAND AS SOON AS PRACTICABLE is defined as
executing a landing to the nearest suitable airfield.
Flight Characteristics Under Partial Power
Conditions. There are no unusual flight characteris-
tics during single-engine operation as long as air-
speed is maintained at or above minimum control
speed (V,,) and above power-off stall speed. The
capability of the aircraft to climb or maintain level
flight depends on configuration, gross weight, alti-
tude, and outside air temperature. Performance and
control will improve by feathering the propeller of
the inoperative engine, retracting the landing gear
and flaps, and establishing the appropriate single-
engine best rate-of-climb speed (V yse). Minimum
control speed (V,,) with flaps retracted is approxi-
mately 1 knot higher than with flaps at takeoff (40%)
b. Engine Malfunction During And After
Takeoff. The action to be taken in the event of an
engine malfunction during takeoff depends on
whether or not liftoff speed (V 1of) has been attained.
If an engine fails immediately after liftoff, many
variables such as airspeed, runway remaining, air-
