usage to check out the initial installation only and future operation and maintenance instructions shall
be obtained from applicable technical manuals.
3.5.9.3 Weight and balance information. This subparagraph is applicable only to airborne weapon systems
(aircraft, missiles, drones, guns, engines, etc). It shall contain suficient data to document the weight and
balance change resulting from TCTO accomplishment. TCTO weight and balance information shall be
3.5.9.3.1 No change in weight and balance. When the weight and balance status of the weapon system is
not changed as a result of TCTO accomplishment, the following statement shall be included: "There are no
weight or balance changes resulting from the instructions contained herein."
3.5.9.3.2 Unknown change in weight and balance. When retroit changes involve structural and/or
subsystem changes which preclude the determination of the actual weight and balance change prior to
TCTO accomplishment, a statement directing the weighing of the weapon system, in accordance with TO
1-1B-50 requirements, shall be made.
3.5.9.3.3 Missile/launch vehicle weight and balance. The preparation of weight and balance data for
missile/launch vehicle TCTOs shall be based on standard weight and balance control system requirements for
space vehicles, as speciied by the acquiring activity (see 6.7.4). The mass and mass properties used
shall be the ones established by the missile/launch vehicle contractor.
3.5.9.3.4 Aircraft/aircraft equipment weight and balance. The simpliied moment system, as outlined in
SAWE-RP7 and TO 1-1B-50 (see 2), shall be followed in the preparation of weight and balance information.
The moment constant shall be the one approved for use by the acquiring activity engineering personnel in
the aircraft -5 series technical manuals. As a minimum, all Chart A entries must be separate Chart C line
entries. Structural and subsystem changes greater than ive pounds shall be listed as separate line items.
Lesser weight may be summed together. TCTO weight and balance information shall be presented in the
following format and shall comply with the preparation requirements and instructions of SAWE-RP7 and TO
1-1B-50 (see Figure 7). "Chart A Entry Information:
NOTE
When a Chart A entry is required and an aircraft inventory is not
accomplished, the date of the entry must be placed (in pencil) in the
item description column of Chart A. Marks in the "IN AIRCRAFT" and
"CHART C ENTRY" columns of Chart A are made only at the time of a
complete aircraft inventory."
Electronic presentation: The acquiring activity shall determine if electronic methods for entry of Chart A
information is used in lieu of print related methods (see 6.2v.). If electronic entry is used, the applicable
interactive terms shall be used in place of "must be placed (in pencil)..." in the statement in the note.

retroit change shall be identiied by technical manual identiication number and date of the basic issue.
If technical manuals are not affected by this retroit change, the words "Not applicable" shall be
