TM 55-1510-219-10 9-30.  LANDING EMERGENCIES. WARNING Structural   damage   may   exist after landing with brake, tire, or landing gear malfunctions. Under  no  circumstances  shall an  attempt  be  made  to  inspect the    aircraft    until    jacks    have been installed. a. Landing Gear Unsafe Indication.  Should one or  more  of  the  landing  gear  fail  to  indicate  a  safe condition, the following steps should be taken before proceeding manually to extend the gear. 1. LANDING GEAR RELAY circuit breaker Check in. 2. Gear lights Check. 3. Gear handle DN. 4. Manual gear extension As required. NOTE If   gear   continues   to   indicate unsafe, attempt to verify position visually by other aircraft. b. Landing Gear Emergency Extension. CAUTION After    an    emergency    landing gear extension has been made, do   not   stow   the   gear   ratchet handle   or   move   any   landing gear    controls    or    reset    any switches    or    circuit    breakers until the cause of the malfunction has been corrected. 1. Airspeed 130 KIAS. 2. LANDING GEAR RELAY circuit breaker Out. 3. Gear handle DN. 4. Landing  gear  alternate  engage  handle Lift and turn clockwise to the stop. 5. Alternate landing gear extension handle Pump. 6. Gear lights illuminated Check. NOTE After a practice manual extension, the alternate handle may be stowed and the landing gear retracted electrically. Rotate    the    alternate    engage handle    counterclockwise    and push     it     down.          Stow     the handle,  push  in  the  LANDING GEAR   RELAY   circuit   breaker on the overhead circuit breaker panel   and   retract   the   gear   in the   normal   manner   with   the landing gear switch. c. Gear-up Landing (All Gear Up or Unlocked). Due    to    decreased    drag    with    the    gear    up,    the tendency  will  be  to  overshoot  the  approach.    The 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. Crew emergency briefing Complete. 2. Loose equipment Stowed. 3. Bleed air valves ENVIRO OFF. 4. Cabin pressure switch DUMP. 5. Cabin  emergency  hatch  Remove  and stow. 6. Seat belts and harnesses Secured. 7. Landing  gear  alternate  engage  handle Disengaged. 8. Alternate landing gear extension handle Stowed. 9. Gear relay circuit breaker In. 10. Gear handle UP. 11. Nonessential electrical equipment OFF. 12. Flaps As required (DOWN for landing). NOTE Fly     a     normal     approach     to touchdown.          After     landing, accomplish the following: 13. Condition levers FUEL CUTOFF. 14. Fire pull handles Pull. 15. Master switch OFF. 9-12
