TM 1-1510-225-10 9-10 away from the burning  wing may  help.    If  a  wing  fire occurs, perform the following: 1.  Perform    engine    shutdown    on    affected side. 2.  Land as soon as possible. d.  Electrical Fire. Upon noting the existence or indications  of  an  electrical  fire,  turn  off  all  affected electrical circuits, if known.  If electrical fire source is unknown, perform the following: 1.  Crew oxygen masks – As required. 2.  Passenger oxygen – As required. 3.  MASTER SWITCH – OFF (visual conditions only). 4.  All nonessential electrical equipment – Off. NOTE With  the  loss  of  DC  electrical  power,  the aircraft   will   de-pressurize.      All   engine instruments,  with  the  exception  of  PROP RPM,   N₁   RPM,   and   ITT   gauges,   will   be inoperative. 5.  BATT switch – ON. 6.  GEN   switches   (individually)   –   RESET, then ON. 7.  Circuit  breakers  –  Check  for  indication  of defective circuit. CAUTION As each electrical switch is returned to ON, note   loadmeter   reading   and   check   for evidence of fire. 8.  Essential     electrical     equipment     –     On (individually until fire source is isolated). 9.  Land as soon as practicable. e.  Smoke and Fume Elimination. To eliminate smoke   and   fumes   from   the   aircraft,   perform   the following: 1.  Crew oxygen masks – 100% and on. 2.  Passenger oxygen – ON. 3.  BLEED  AIR  VALVE  switches  –  PNEU  & ENVIR OFF. 4.  VENT BLOWER switch – AUTO. 5.  AFT BLOWER switch – OFF. 6.  CABIN TEMP MODE switch – OFF. 7.  If  smoke  and  fumes  are  not  eliminated: CABIN PRESS switch – DUMP. NOTE   R Opening storm window, after depressurizing,   will   facilitate   smoke   and fume removal. 8.  Passenger     oxygen     masks     –     Check. Confirm  that  all  passengers  are  receiving supplemental oxygen. 9.  Engine Oil Pressure – Monitor. 9-27.  FUEL SYSTEM. a.  FUEL  PRESS  Warning  Light  Illuminated. Illumination of the L  or R FUEL PRESS warning light usually indicates failure of the respective engine-driven boost pump.  Perform the following: 1.  STANDBY PUMP switch – ON. 2.  FUEL PRESS light out – Check. 3.  FUEL   PRESS    light    still    illuminated    – Record unboosted time. b.  NO TRANSFER Indicator Light Illuminated (Fuel   Panel).      Illumination   of   a   NO   TRANSFER indicator  light  with  fuel  remaining  in  the  respective auxiliary fuel tank indicates a failure of that automatic fuel transfer system.  Proceed as follows: 1.  AUX TRANSFER switch (affected side) – OVERRIDE. 2.  Auxiliary fuel quantity – Monitor. 3.  AUX  TRANSFER  switch  (after  respective auxiliary fuel has completely transferred) – AUTO. c.  Nacelle Fuel Leak.  If nacelle fuel leaks are evident, perform the following: 1.  Perform engine shutdown.
