TM 1-1510-218-10 9-10 c.   Wing Fire.  There is little that can be done to control a wing fire, except to shut off fuel and electrical systems  that  may  be  contributing  to  the  fire  or  that could  aggravate  it.    Diving  and  slipping  the  aircraft 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 if fire continues. 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 procedure. 1.   Crew oxygen masks – As required. 2.   Passenger oxygen – As required. 3.   MASTER     SWITCH     –     OFF.          (Visual conditions only). 4.   AII   nonessential   electrical   equipment   – OFF. NOTE With  the  loss  of  dc  electrical  power,  the aircraft   will   depressurize.      All   electrical instruments, with the exception of the Prop RPM,   N₁   RPM,   and   TGT   gauges,   will   be inoperative. 5.   BATT switch – ON. 6.   Generator switches (individually) – RESET, then ON. 7.   Circuit  breakers  –  Check  for  indication  of defective circuit. CAUTION As each electrical switch is returned to ON, note   load   meter   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. 1.   Crew oxygen masks – 100% and on. 2.   Passenger oxygen – ON. 3.   BLEED  AIR  VALVE  switches  –  ENVIRO OFF. 4.   VENT BLOWER switch – AUTO. 5.   AFT VENT BLOWER switch – OFF. 6.   CABIN AIR/TEMP MODE switch – OFF. 7.   If  smoke  and  fumes  are  not  eliminated, CABIN PRESS switch – DUMP. NOTE Opening the 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   No.   1   or   No.   2   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    on    –    Record unboosted time. b.  No Fuel Transfer Caution Light Illuminated. Illumination of a No 1 or No 2 NO FUEL XFR    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 following procedure.
