TM  55-1510-222-10 which   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. 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 - On and 100%. 2. Master   switch   -   OFF      (visual   conditions only). 3. All nonessential electrical equipment - Off. NOTE With loss of DC electrical power, the air-    craft    will    depressurize.        All electrical instruments, with the exception   of   the   propeller   RPM,   N. RPM, and TGT gages will be inoperative. 4. Battery switch - ON. 5. Generator  switches  (individually)  -  RESET, then ON. 6. 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. 7. Essential electrical equipment - On (individually until fire source is isolated). 8. Land as soon as practicable. e. Smoke and Fume Elimination.  To eliminate smoke    and    fumes    from    the    aircraft,    perform    the following: 1. Crew oxygen - On and 100%. 2. Bleed air valve switches - PNEU ONLY. 3. FWD Vent blower switch - AUTO. 4. AFT vent blower switch - Off. 5. Cabin  temperature  mode  selector  switch  - OFF. 6. If  smoke and fumes are not eliminated: Cabin   pressure   dump   switch   -   CABIN   PRESS DUMP. NOTE Opening storm window (after depressurizing)  will  facilitate  smoke and fume removal. 7. Engine instruments - Monitor. 9-26.  FUEL SYSTEM. a. Fuel Pressure Warning Annunciator Illuminated.    Illumination  of  the  #1  or  #2  FUEL  PRESS warning   annunciator   usually   indicates   failure   of   the respective   engine-driven   boost   pump.      Perform   the following: 1.   Standby pump switch - ON. 2. Fuel   pressure   annunciator   extinguished   - Check. 3. Fuel  pressure  annunciator  still  illuminated  - Record unboosted time. 4. Monitor system for further abnormal indications. b. No     Fuel     Transfer     Caution     Annunciator Illuminated.    Illumination  of  a  #1  or  #2  NO  FUEL  XFR annunciator    with    fuel    remaining    in    the    respective auxiliary  fuel  tank  indicates  a  failure  of  that  automatic fuel transfer system.  Proceed as follows: 1. Auxiliary   transfer   switch   (affected   side)   - OVRD. 2. Auxiliary fuel quantity - Monitor. 3. Auxiliary   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. 2. Fire pull handle - Pull. 3 Land as soon as practicable. d.   Fuel  Crossfeed.    For  fuel  crossfeed,  perform the following: 1. Auxiliary transfer switches - AUTO. NOTE With   the   fire   pull   handle   pulled,   the fuel 9-9
