Subtract total weight and moment of items entered in column I. These items should not be checked
on chart A as IN AIRCRAFT.
Add total weight and total moment of items in column II. These items must be checked in chart A as IN
AIRCRAFT to indicate their inclusion in the basic weight. If aircraft is weighed after overhaul with a
completely dry fuel or oil system, include trapped fuel or oil in column II.
Enter new basic weight and moment/constant on DD Form 365-3. All subsequent aircraft loadings will be
based on the latest figures entered on DD Form 365-3.
Fill in reactions and type scales used.
Include under REMARKS, information as to attitude of aircraft when weighed, method of support, etc.
G-9. Basic Weight and Balance Record, DD Form 365-3 (Figure G-4). DD Form 365-3 is a continuous history
of the basic weight, moment, and balance computer index resulting from structural and equipment changes in
service. At all times the last weight, moment/constant, and index entry is considered the current weight and balance
status of the basic aircraft. The basic index for the balance computer can be determined by means of the index
scale or index formula on the computer.
At time of delivery of a new aircraft, the manufacturer entered on this chart the basic weight,
moment/constant, and index of the aircraft. The itemized list of the equipment included herein is shown
and checked on chart A in the IN AIRCRAFT column.
Make additions to or subtractions from basic weight and moment on DD Form 365-3 when:
Equipment is added to or removed from the aircraft. If item is listed on DD Form 365-1, enter identical
item number, description and applicable weight, arm, and moment data on DD Form 365-3. If item is
not listed on DD Form 365-1, determine its actual weight and arm, and record this information
on both DD Form 365-1 and DD Form 365-3.
Do not enter check marks on DD Form 365-1 for these items until a complete inventory is made,
but enter the date in parentheses following the description.
A complete inventory reveals equipment changes not previously recorded. Post equipment changes
as noted above. Date newly calculated basic weight and moment to correspond with date entered at
head of CHECK column on DD Form 365-1 identifying equipment content of new figures. It is also
helpful to record the check column number which substantiates this new basic weight and moment.
Structural changes are made in the aircraft. If structural changes are provisions for equipment, list
them separately from equipment to be installed thereon.
The aircraft is reweighed. Before weighing make a complete inventory and bring calculated DD
Form 365-3 figures up to date. Enter new as weighed basic weight and moment from aircraft
Any changes or modifications which are caused by a specific order should carry a reference to the order
number and date which authorizes the change.
The date entered on DD Form 365-3 must be consistent with the delivery date or the date
entered on the top of the CHECK column on DD Form 365-1 and with the date on the aircraft
weighing record if used.
