TM 1-1520-240-BD CHAPTER 10 FUEL SYSTEM SECTION I.  GENERAL 10-1.      INTRODUCTION .      This      chapter      provides methods for assessing battle-damage, deferring damage repair,    and    repairing    fuel    systems.        The    primary emphasis  is  on  providing  the  assessor  with  the  proper guidance to perform the assessment process. Simplified  logic  trees  and  related  illustrations  will  also aid the assessor. SECTION II.  DAMAGE ASSESSMENT 10-2.    DAMAGE  ASSESSMENT  PROCEDURE.    Each fuel  tank  must  be  carefully  evaluated  and  classified. Examine  both  confined  areas  and  open  areas  exposed to    the    airstream.        Determine    which    leaks    require immediate repair before flight and which leaks are not a flight  hazard.    Determine  the  exact  location  of  a  leak and thoroughly examine the leak area.  Refer to Figure 10-1 for assessment logic. 10-3.   DEFERMENT.    Scheduled  maintenance  may  be deferred.  Unscheduled maintenance such as the repair of  systems  and  subsystems  which  are  not  critical  to mission  accomplishment,  may  be  deferred  if  safety  of flight is not significantly degraded.  Requirements must be examined to determine if relaxed standards for repair and    aircraft    performance    can    be    accepted.        The commander  may  defer  combat  maintenance  and  battle damage   repair,   even   if   doing   so   places   operational limitations on the aircraft. SECTION III.  BATTLE-DAMAGE REPAIR 10-4.     FUEL   TANKS.      Battle-damage   repair   of   fuel tanks is limited to those repairs specified in this manual. 10-5.    FUEL  SYSTEM  SEALS.    Preformed  packings removed  during  fuel  system  component  maintenance may be reused if they are not damaged or swelled to a point  where  they  do  not  fit  snugly  into  the  preformed paddngs  groove.    Swelled  preformed  packings  may  be reused   if   they   are   allowed   to   dry   and   shrink   to   the original size.  Seals composed of rubber inserts may be reused if they are not damaged or if compression set is not  more  than  60  percent  when  compared  with  a  new gasket. CAUTION Reused     preformed     packings     and seals  must  be  inspected  after  every flight for leakage until replaced. 10-1
