Inspect aircraft for equipment actually installed, placing check marks in the next unused IN AIRCRAFT
column. A check in the column headed IN AIRCRAFT indicates the presence of the item in the
aircraft on the date at the head of the column, and a zero (0) indicates its absence. Items should
not be checked unless they are installed, and items marked zero are not to be included in the basic
weight and balance tabulated on DD Form 365-3 for the corresponding date. During this inventory,
note whether any new items of equipment have been installed, and if so, enter item number and name
or description, together with other data required through column moment/constant, including date in
parentheses following description.
