TM 55-1510-221-10 CHAPTER  9 EMERGENCY  PROCEDURES Section I.   AIRCRAFT  SYSTEMS 9-1.  AIRCRAFT  SYSTEMS. 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  Operator’s  and  Crewmember’s  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 malfunction. 9-5. EMERGENCY EXITS AND EQUIPMENT. Emergency  exits  and  equipment  are  shown  in figure  9-1. 9-6. EMERGENCY ENTRANCE. 9-2. IMMEDIATE ACTION EMERGENCY CHECKS. 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 procedures. 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. NOTE 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 malfunctions. 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. a. 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%) 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 (V _1of) has been attained. If  an  engine  fails  immediately  after  liftoff,  many variables such as airspeed, runway remaining, air- 9-1
