TM 55-1500-342-23 CHAPTER 4 WEIGHT AND BALANCE RECORDS Section I.  TYPES OF FORMS 4-1.    General.    Specific   weight   and   balance   data   is contained    in    the    -10    operator's    manual    and    the applicable  maintenance  manual  for  each  Army  aircraft. Standard forms are used in conjunction with this data to provide an effective  system   for  weight  and  balance control.      Information   to   be   inserted   on   the   charts   or forms  is  applicable  only  to  the  individual  aircraft,  the serial  number  of  which  appears  on  the  various  charts and  forms.    The  weight  and  balance  data  and  related forms for aircraft are maintained in accordance with AR 95-3.  Entries on DD Form 365, 365-1, 365-2, and 365-3 will be made using a pen, typewriter, or a rubber stamp. Felt tip pens or grease pencils will not be used.  Pencils may be used on DD Form 365-4.  The forms referred to herein  may  differ  from  time  to  time,  but  the  general principles    behind    their    use    will    remain    the    same. Weight    and    balance    of    aircraft    is    controlled    and standardized through the use of the following charts and forms: a.    DD  Form  365  (Record  of  Weight  and  Balance Personnel). b.    DD  Form  365-1  (Chart  A  Basic  Weight  Check List Record). c.    DD    Form    365-2    (Form    B    Aircraft    Weight Record). d.    DD   Form   365-3   (Chart   C   Basic   Weight   and Balance Record). e.    DD  Form  365-4  (Form  F  Weight  and  Balance Clearance). f.    Chart  E  (Loading  Data  and  Special  Weighing Instructions). 4-2.      Responsibility   for   DD   Form   365   Series   and Chart     E.          Before     delivery     of     an     aircraft,     the manufacturer   is   responsible   for   inserting   all   aircraft identifying  data  on  the  various  charts  and  forms.    The manufacturer  completes  all  forms.    All  DD  Form  365 series charts and any other pertinent weight and balance data   relating   to   an   aircraft   will   be   maintained   in   a permanent binder for the aircraft.  The binder and all forms contained therein will bear the aircraft designation and   serial   number.      Any   change   that   affects   aircraft weight and balance will be reflected in these forms. 4-3.      Disposition   of   Weight   and   Balance   Forms. Weight  and  balance  forms  are  to  be  safeguarded  and maintained with the same degree of importance as other records maintained for each aircraft. a.    The  individual  weight  and  balance  forms  serve various purposes.  Therefore, the retention period of the forms will vary, as follows: (1) The DD Form 365 (Record of Weight and Balance Personnel) is a semi-permanent form.  It will be retained  in  the  aircraft's  weight  and  balance  data  file until  space  for  additional  entries  has  been  exhausted and a new replacement form started.  At that time, the replaced form may be destroyed locally. (2) The DD Form 365-1 (Basic Weight Check List) and the DD Form 365-3 (Basic Weight and Balance Record)   are   permanent   forms.      These   forms   will   be retained in the aircraft's weight and balance data file for the   life   of   the   aircraft.      As   new   forms   are   started because  of  exhausting  entry  space,  the  new  forms  will be stapled to the original form. (3) The   DD   Form   365-2   (Aircraft   Weighing Record)    is    a    semi-permanent    form.        The    current completed  form  will  be  retained  in  the  aircraft's  weight and    balance    data    file    until    the    aircraft    has    been reweighed,  a  new  form  started,  computations  verified, and  necessary  entries  made  on  the  DD  Form  365-3. Upon completion of the above, the old DD Form 365-2 may be destroyed locally. (4) The DD Form 365-4 (Weight and Balance Clearance  Form  F)  which  has  been  used  to  compute standard    loads,    utilizing    the    aircraft's    current    basic weight, is considered a current work form as long as the load  weights  and  locations  remain  current  and  until  the basic aircraft weight has been recomputed/changed.  A copy of the current form will be retained in the aircraft's weight  and  balance  data  file  until  the  entries  require revision,  at  which  time  the  old  form  will  be  destroyed locally or marked void.
