TM 55-1510-220-10 8. Touchdown On safe main gear first. NOTE Fly    a    normal    approach    to    touchdown. After landing, accomplish the following: 9. Power levers (runway assured) IDLE. (10) Condition levers FUEL CUTOFF. (11) Fire pull handle Pull. (12) Master switch OFF. f. 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. 9-25.    LANDING  WITH  INOPERATIVE  WING  FLAPS (UP). The aircraft does not exhibit any unusual characteristics when landing with the wing flaps up.  The approach   angle   will   be   shallow   and   the   touchdown speed will be higher resulting in a longer landing roll. 9-26.  CRACKED WINDSHIELD. a. External Crack.  If an external windshield 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: 1. Descend to below 25,000 feet. (2) Cabin Pressure Reset pressure differential   to   4   PSI   or   less   within   10 minutes. 9-27.  CRACKED CABIN WINDOW. If   a   crack   in   a   single   ply   of   the   external   cabin window, unpressurized flight may be continued. Proceed as follows. 1. Oxygen As required. 2. Cabin pressurization Depressurize. 3. Descend As required. NOTE If  both  plys  of  the  external  cabin  window have  developed  cracks,  the  aircraft  shall not  be  flown,  once  landed,  without  proper ferry flight authorization. 9-28.  DELETE 9-29.  DITCHING. If   a   decision   to   ditch   is   made,   immediately   alert   all crewmembers    to    prepare    for    ditching.        Plan    the 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  110-120  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 on impact may result in the aircraft pitching forward and "digging in." Expect more than one 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.  In a planned 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.    After  exiting  the  aircraft,  keep  the raft away from any damaged surfaces which 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.  Refer to  figure  9-3  for  body  positions  during  ditching.    Figure 9-4 shows wind swell information.  Perform the following procedures: Change 2  9-15
