GENERAL INFORMATION
G-1. WEIGHT AND BALANCE.
a.
This appendix contains procedures required for intermediate maintenance personnel to perform their
phase of the weight and balance control. The procedures are specifically applicable to the CH-47D and
include the use of certain forms in the DD 365 series. For general weight and balance information,
refer to TM 55-1500-342-23. It is not the intent of this appendix to duplicate information contained in
TM 55-1500-342-23.
b.
The weight and balance data provides the service activities with a standard system of intermediate
maintenance weight and balance control. It contains brief instructive information to be used with the forms
and charts which provide for continuous control of weight and balance of the aircraft. The data to be
inserted on the charts and forms are applicable only to the individual aircraft, the serial number of which
appears on the various forms and charts. These data are to remain with the aircraft in accordance with
existing directives. The charts and forms referred to herein may differ in nomenclature and arrangement
from those shown in previously published copies, since these charts are revised from time to time;
however, the general principle of use will not change.
G-2. Responsibility. The aircraft manufacturer inserts all aircraft identifying data on the various charts, including
one sample weight and balance clearance DD Form 365F, if applicable, at time of delivery. This record constitutes
the basic weight and balance data of the aircraft at delivery. It is the maintenance officer’s responsibility to monitor
the technician who maintains the weight and balance data records. These data shall be maintained in a permanent
binder for each aircraft. The binder shall reflect the model designation and the aircraft serial number. All DD
Form 365 series forms, charts, and any other pertinent weight and balance data shall be maintained therein. All
subsequent changes in weight and balance are compiled by the weight and balance technician in accordance
with instructions contained herein.
G-3. Weight definition. Tare is the weight of equipment necessary for weighing the aircraft (chocks, blocks, slings,
jacks, etc.) which is included in the scale reading (or reactions) but is not a part of the aircraft weight. Reference is
made to TM 55-1500-342-23 for weight and balance definitions.
