center-of-gravity with the gear retracted is aft of the main wheels. This condition will allow the aircraft to  be  landed  with  the  gear  retracted  and  should result in a minimum amount of structural damage to the aircraft, providing the wings are kept level. It is recommended that the fuel load be reduced and the landing  made  with  flaps  fully  extended  on  a  hard surface  runway.  Landing  on  soft  ground  or  dirt  is not recommended as sod has a tendency to roll up into  chunks,  damaging  the  underside  of  the  aircraft’s structure. When fuel load has been reduced, prepare for a gear-up landing as follows: 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. Crew  emergency  briefing  -  Complete. Loose equipment - Stowed. Bleed  air  valve  switches  -  ENVIRO OFF. Cabin pressure dump switch - CABIN PRESS  DUMP. Cabin emergency hatch - Remove and stow. Seat  belts  and  harnesses  -  Secured. Landing  gear  alternate  engage  handle  - Disengaged. Alternate  landing  gear  extension  handle - Stowed. Gear relay circuit breaker - In. Gear - UP. Nonessential  electrical  equipment  - OFF. Flaps  -  As  required  (DOWN  for  land- ing). NOTE Fly   a   normal   approach   to   touchdown. After  landing,  accomplish  the  following: 13. Power levers (runway assured) - IDLE. 14. Condition  levers  -  FUEL  CUTOFF. 15. Fire pull handles - Pull. 16. Master switch - OFF. d.  Landing  With  Nose  Gear  Unsafe.  If  the landing gear control switch handle warning light is illuminated  and  the  nose  GEAR  DOWN  indicator light  shows  an  unsafe  condition,  the  nose  gear  is probably  not  locked  down,  and  the  gear  position should  be  checked  visually  by  another  aircraft,  if possible. If all attempts to lock the nose gear fail, a landing  should  be  made  with  the  main  gear  down and locked. Hold the nose off the runway as long as TM  55-1510-221-10 possible  and  do  not  use  brakes.  Use  the  following procedures: 1. Crew  emergency  briefing  -  Complete. 2.  Loose  equipment  -  Stowed. 3.  Bleed  air  valve  switches  -  ENVIRO OFF. 4.  Cabin  pressure  dump  switch  -  CABIN PRESS DUMP. 5. Cabin emergency hatch - Remove and stow. 6. Seat  belts  and  harnesses  -  Secured. 7.   Nonessential   electrical   equipment   - OFF. NOTE Fly   a   normal   approach   to   touchdown. After  landing,  accomplish  the  following: 8. Power levers (runway assured) - IDLE. 9. Condition  levers  -  FUEL  CUTOFF. 10. Fire pull handle - Pull. 11. Master switch - OFF. e. Landing  With  One  Main  Gear  Unsafe.  If one  main  landing  gear  fails  to  extend,  retract  the other gear and make a gear-up landing. If all efforts to  retract  the  extended  gear  fail,  land  the  aircraft  on a hard runway surface, touching down on the same edge of the runway as the extended gear. Roll on the down and locked gear, holding the opposite wing up and the nose gear straight as long as possible. If the gear has extended, but is unsafe, apply brakes lightly on the unsafe side to assist in locking the gear. If the gear  has  not  extended  or  does  not  lock,  allow  the wing to lower slowly to the runway. Use the follow- ing  procedures: 1. Crew  emergency  briefing  -  Complete. 2.  Loose  equipment  -  Stowed. 3.  Bleed  air  valve  switches  -  ENVIRO OFF. 4.  Cabin  pressure  dump  switch  -  CABIN PRESS DUMP. 5.  Cabin  emergency  hatch  -  Remove  and stow. 6. Seat  belts  and  harnesses  -  Secured. 7.   Nonessential   electrical   equipment   - OFF. 9-13
