TM 55-1510-219-10 CHAPTER 9 EMERGENCY PROCEDURES Section I.  AIRCRAFT SYSTEMS 9-1.  AIRCRAFT SYSTEMS. This  section  describes  the  aircraft  systems emergencies   that   may   reasonably   be   expected   to occur  and  presents  the  procedures  to  be  followed. Emergency  procedures  are  given  in  checklist  form when   applicable.      A   condensed   version   of   these procedures  is  in  the  Operator's  and  Crewmember's Checklist, TM 55-1510-219-CL. Emergency operations  of  avionics  equipment  are  covered  when appropriate in Chapter 3, Avionics, and are repeated in this section only as safety of flight is affected. 9-2.  IMMEDIATE ACTION EMERGENCY CHECKS. Immediate     action     emergency     items     are underlined 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 procedures. NOTE The urgency of certain emergencies requires immediate  action  by  the  pilot. The     most     important     single consideration is aircraft control.      All   procedures   are subordinate to this requirement. 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 POSSIBLE  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. 9-4.  AFTER EMERGENCY ACTION. 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 malfunction. 9-5.  EMERGENCY EXITS AND EQUIPMENT. Emergency  exits  and  equipment  are  shown in figure 9-1. 9-6.  EMERGENCY ENTRANCE. Entry    may    be    made    through    the    cabin emergency  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. a. Flight   Characteristics   Under   Partial   Power Conditions. There are no unusual flight characteristics during single-engine operation as long as   airspeed   is   maintained   at   or   above   minimum control speed (Vmc) and power-off stall speeds.  The capability  of  the  aircraft  to  climb  or  maintain  level flight     depends     on     configuration,     gross     weight, altitude, and free 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  (Vyse).    Minimum  control speed  (Vmc)  with  flaps  retracted  is  approximately  1 knot | higher than with flaps at takeoff (40%) position. 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 (V1of) has been attained. If   an   engine   fails   immediately   after   liftoff,   many variables    such    as    airspeed,    runway    remaining, aircraft weight, altitude at time of engine failure, and single-engine   performance   must   be   considered   in deciding whether it is safer to land or continue flight. c. Engine  Malfunction  Before  Liftoff  (Abort).    If an engine fails and the aircraft has not accelerated 9-1
