TM 55-1510-220-10 2.    If fire pull handle light out is extinguished:          Advance power. 3.    If fire pull handle light is still illuminated:            Engine fire in flight procedures (identified)         Perform. NOTE Flight  into  the  sun  at  high  aircraft  pitch attitude    may    actuate    the    fire    warning system. Lowering the nose and/or changing  headings  will  confirm  a  warning system failure caused by sun rays. (3)    Engine fire in flight (identified).  If an engine fire is confirmed in flight, perform the following:  i CAUTION Due to the possibilities of fire warning system malfunctions, the fire should be visually identified before the engine is secured and the extinguisher actuated. 1.    Power lever- IDLE. 2.    Propeller lever - FEATHER. 3.    Condition lever - FUEL CUTOFF. 4.    Fire pull handle - Pull. 5.    Fire extinguisher - Actuate as required. (6.) Engine cleanup - Perform. b. Fuselage Fire.   If a fuselage fire occurs,  perform the following: WARNING The extinguisher agent (Bromochlorodifluoromethane)   in   the   fire extinguisher  can  produce  toxic  effects  if inhaled. 1.    Fight the fire. 2.    Land as soon as possible. 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 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 - 100%. (2.) Master switch - OFF (visual conditions only). 3. All nonessential electrical equipment - OFF. NOTE With    loss    of    DC    electrical    power,    the aircraft   will   depressurize.      All   electrical instruments,    with    the    exception    of    the propeller  RPM,  N 1 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 - 100% and ON. 9-10
