TM 1-1510-225-10 9-13 2.  LANDING GEAR RELAY and GEAR IND circuit breakers – Check in. 3.  GEAR DOWN lights – Check illuminated. IF INDICATOR REMAINS UNSAFE: 4.  Landing gear manual extension – Perform. b.  Landing Gear Manual Extension. 1.  Airspeed – Below 181 KIAS. 2.  LANDING GEAR RELAY circuit breaker – Pull. 3.  LDG GEAR CONTROL – DN. CAUTION If all three of the green GEAR DOWN lights do  not  illuminate,  continue  pumping  until sufficient  resistance  is  felt  to  ensure  the gear is down and locked.   DO NOT  STOW THE MANUAL  EXTENSION LEVER,  LEAVE IT IN THE UP POSITION. 4.  Manual extension lever – Unstow.  Pump until the three  green  GEAR  DOWN lights are illuminated and resistance is felt. 5.  Manual  extension  lever  –  If  three  green GEAR DOWN lights are illuminated, stow the lever. CAUTION After a manual landing gear extension has been  made  due  to  a  malfunction  of  the system,   do   not   move   any   landing   gear controls  or  reset  any  switches  or  circuit breakers until the cause of the malfunction has been corrected.  The malfunction may be in the gear up circuit and the gear might retract on the ground. c.  Gear-up  Landing  (All  Gear  Up).    Due  to decreased  drag  with  the  gear  up,  there  may  be  a tendency to overshoot the desired landing point.  The center   of   gravity   will   be   aft   of   the   main   wheels, allowing  the  aircraft  to  be  landed   with   a  minimum amount  of  structural  damage  to  the  aircraft  provided the wings are kept level.  It is recommended the fuel load be reduced and the landing made  with the flaps fully   extended.    A   hard  surface  runway  should   be utilized for the landing whenever possible.  Landing on soft   ground   is   not   recommended,   as   sod   has   a tendency   to   roll   up   into   chunks   and   damage   the underside of the aircraft structure.  When fuel load has been   reduced,   prepare   for   a   gear   up   landing   as follows: 1.  Fuel load – Reduce. 2.  Personnel emergency briefing – Complete. 3.  Loose equipment – Stow/secure. 4.  BLEED   AIR   VALVES    –    ENVIR   OFF (below 10,000 feet). 5.  CABIN PRESS switch – DUMP. Prior   to   removing   the   emergency   exit hatch, slow to a safe airspeed (approximately   160   KIAS   or   below)   and ensure  passengers  are  seated  with  seat belts   fastened   and   all   loose   equipment secured. 6.  Emergency   exit   hatch   –   Remove   and stow. 7.  Seat belts and harnesses – Fasten. 8.  Gear manual extension handle – Stow. 9.  LDG GEAR CONTROL – UP. 10.   LANDING GEAR RELAY circuit breaker – Pull. 11.   LANDING    GEAR    WARN    horn    circuit breaker – Pull. 12.   Nonessential electrical equipment – Off. NOTE Fly   a   normal   approach   to   touchdown. Avoid    touching    down    in    a    nose-high attitude. 13.   FLAPS – As required (DOWN is recommended for landing). 14.   POWER lever – IDLE when landing on the desired touchdown area is assured. 15.   CONDITION lever – FUEL CUTOFF. 16.   Fuel   FIREWALL  SHUTOFF  VALVES   – CLOSED.
