TM 1-1510-224-10 5. Yaw damp - Off. (6) BRAKE deice switch - Off. 9-14.  SINGLE-ENGINE LANDING CHECK. Perform the following procedure during final approach to runway. 1. Autopilot/yaw damp - Disengage. 2. GEAR DOWN lights - Check. 3. PROP lever (operative engine) - HIGH RPM. NOTE To ensure constant reversing characteristics,  the  propeller  control must be in the HIGH RPM position. 4. Flaps - As required. 9-15.  SINGLE-ENGINE GO-AROUND. The  decision  to  go  around  must  be  made  as  early  as possible.    Elevator  forces  at  the  start  of  the  go-around are   very   high,   and   a   considerable   amount   of   rudder control will also be required at low airspeeds.  Retrim as required.    If  rudder  application  is  insufficient,  or  applied too  slowly,  directional  control  cannot  be  maintained.    If control  difficulties  are  experienced,  reduce  power  on  the operating  engine.    Ensure  the  aircraft  will  not  touch  the ground  before  retracting  the  landing  gear.    Retract  the flaps   only   as   safe   airspeed   permits.      Retract   flaps   to APPROACH position until V_ref , then UP.  Perform single- engine go-around as follows: 1. Power - Maximum allowable. 2. Gear- UP. 3. Flaps - UP. 4. Airspeed - V,. 5. Landing lights - OFF. 9-16.    TWO  ENGINES  INOPERATIVE/OFF  AIRFIELD LANDING. NOTE With   propellers   feathered,   there   is less  drag  and  the  aircraft  will  have  a tendency   to   overshoot   the   planned touchdown point. When   landing   on   rough   terrain   or unprepared     surfaces,     the     landing gear     will     absorb     landing     energy during touchdown, if extended. Select  landing  gear  up  or  down  as  best  suits  the conditions  of  the  landing  site.    If  gear-up,  follow  gear-up landing    procedure.        If    gear-down,    make    a    normal touchdown and use brakes as required. 9-17.  LOW OIL PRESSURE. In  the  event  of  a  low  oil  pressure  indication,  perform procedures as applicable: 1. Oil  pressure  below  90  PSI  and  above  60  PSI: Torque - As required (54% maximum). 2. Oil pressure below 60 PSI: Perform engine shut- down,   or   land   as   soon   as   practicable   using minimum power to ensure safe arrival. 9-18.    L  OR  R  CHIP  DETR  WARNING  ANNUNCIATOR ILLUMINATED. If    the    L    CHIP    DETR    or    R    CHIP    DETR    warning annunciator illuminates, and safe single-engine flight can be maintained: 1. Perform engine shutdown. 2. Land as soon as practicable. 9-19.    DUCT  OVERTEMP  CAUTION  ANNUNCIATOR ILLUMINATED. Ensure the cabin floor outlets are open and unobstructed,     then     perform     the     following     steps     in sequence  until  the  annunciator  is  extinguished.    Allow approximately  30  seconds  after  each  adjustment  for  the system  temperature  to  stabilize.    The  over  temperature condition is considered corrected at any point during the procedure that the annunciator extinguishes. (1) CABIN AIR control - In. (2) CABIN AIR MODE SELECT switch - AUTO. (3) CABIN AIR TEMP control - DECREASE. (4) FWD VENT BLOWER switch - HIGH. (5) CABIN AIR MODE switch - MAN COOL. (6) CABIN AIR MANUAL TEMP switch - DECREASE (hold). (7) LEFT    ENVIRO    &    PNEU    BLEED    AIR    valve switch - PNEU ONLY. (8) Light   still   illuminated   after   30   seconds:   LEFT ENVIRO & PNEU BLEED AIR valve switch - ON. (9) RIGHT   ENVIRO   &   PNEU   BLEED   AIR   valve switch - PNEU ONLY. 9-8
