TM 55-1500-342-23 (5) The   manufacturer   of   the   aircraft   places check marks or zeros in the first IN AIRCRAFT column under   the   RECORD   OF   CHECKING   section   of   the CHART  A.    This  is  done  at  the  time  of  delivery  of  the aircraft  to  indicate  its  delivery  condition.    This  delivery inventory  shows  the  equipment  that  is  included  in  the aircraft's initial basic weight and moment as listed on the CHART C, DD Form 365-3. d.    ALL   CHART   A   inventories   subsequent   to   the manufacturers delivery inventory shall be completed as follows: (1) Inspect the aircraft for equipment actually installed.    Place  the  date  on  which  the  inventory  was made   at   the   top   of   the   next   unused   RECORD   OF CHECKING  column.    If  all  columns  have  been  used, complete a new DD Form 365-1 and mark the entries in column    1.        Place    a    check    in    the    IN    AIRCRAFT COLUMN   if   in   the   aircraft   or   a   zero   to   indicate   its absence.    When  missing  basic  weight  items  are  added to column II on the reverse side of FORM B, they should be checked on CHART A as IN AIRCRAFT. NOTE Marks   in   the   IN   AIRCRAFT   and   CHART   C ENTRY columns are made only at the time of a   complete   inventory.      Never   change   the marks  or  add  new  ones  under  a  previously accomplished inventory. (2) Compare  this  new  inventory  with  the  last completed inventory under the RECORD OF CHECKING  column,  noting  any  changes  in  the  items installed in the aircraft.  Refer to CHART C to ascertain whether  the  necessary  weight  and  moment  corrections have  been  made.    If  so,  place  check  marks  opposite such items in the CHART C ENTRY column of CHART A.      If   not,   correct   the   calculated   basic   weight   and moment data on CHART C and then enter the CHART C  ENTRY  column  check  marks.    A  check  mark  in  the CHART C ENTRY column indicates that the appropriate weight  and  moment  change  has  been  recorded  on  the CHART C.  Make sure that the inventory date is entered in the RECORD OF CHECKING column on the CHART A.    Enter  the  same  date  in  the  DATE  column  of  the CHART  C  for  the  corresponding  weight  and  moment calculations. e.    When  a  new  item  of  equipment  which  is  not listed    on    the    CHART    A    is    added    to    the    aircraft, determine    its    weight,    arm    and    moment    from    the applicable    MWO    or    by    actual    measurement    and calculation.        Enter    an    item    number,    the    name    or description,  weight  arm  and  simplified  moment  on  an open line under the proper compartment on the CHART A.    Also,  make  required  entry  on  CHART  C.    When  a new    CHART    A    is    initiated,    the    entries    should    be rearranged so that the equipment within each  compartment  is  listed  such  that  the  arms  (in  the column   titled   "ARM')   progress   numerically   from   the forward  to  the  aft  limit  of  each  compartment.    Then numerically rearrange item numbers in sequence. f.    CHART  A  is  used  primarily  as  a  record  of  all  items installed   at   the   time   the   aircraft   is   weighted.      When equipment     is     permanently     removed,     refer     to     the instructions    for    CHART    C    form    entries.        When    a complete inventory is made, line completely through the removed items from the compartment and item number column  through  the  check  column  on  the  CHART  A. When  all  the  check  column  blocks  have  been  filled,  it will  not  be  necessary  to  include  those  items  lined  out when initiating new forms. 4-7.  DD Form 365-2 (Aircraft Weighing Record).  The actual weighing data is listed on DD Form 365-2 (figure 4-3)    with    comments    denoting    the    type    of    scales. reactions, and other pertinent information.  Diagrams of the  aircraft  are  shown  to  illustrate  dimensions  required during  weighing  process.    Form  entries  are  made  as follows: a.    Fill   in   identifying   data   and   enter   actual   scale reading in first column. b.    Record     measurements     taken     at     time     of weighing.    Only  dimensions  B  and  D  need  actually  be measured.    Distance  I,  from  the  reference  datum  to  jig point, is obtained from CHART E data.  Dimension E is determined by addition or subtraction. c.    Tare  is  the  weight  of  supports,  such  as  jacks,  that may be placed on a platform scale to raise the aircraft. The  term  ordinarily  pertains  to  the  use  of  mechanical type scales.  The TARE column shall be used to record tare    or    correction    factors.        Follow    the    instructions provided   in   the   Technical   Manuals   for   the   specific weighing system being used to arrive at net weight. d.    Record   weight   and   moment   of   all   items   in aircraft when weighed that are not a part of basic weight (COLUMN   I,   reverse   side   of   aircraft   weighing   record form). e.    Record  weight  and  moment  of  all  basic  items that  were  not  in  aircraft  when  weighed  (COLUMN  II, reverse  side  of  aircraft  weighing  record  form).    Items listed in this column must be checked on CHART A as IN AIRCRAFT to indicate their inclusion in basic weight. f.    Multiply   subtotal   net   weight   of   reaction   (jack points) by their respective arms (dimensions E and F) to obtain their moments. g.    Add net weights and moments of reaction (jack points).
