Selection of Materials.-  Specifications and standards for all materials,
parts, and Government certification and approval of processes and equipment, which are
not specifically designated herein and which are necessary for the execution of this
specification, shall be selected in accordance with ANA Bulletin No. 143. except as pro-
vided in the following paragraph.
AN or JAN Standard Parts.-  AN or JAN Standard parts shall be used wherever
5.1.2.1
they are suitable for the purpose, and shall be identified on the drawing by their part
numbers.  Commercial utility parts such as screws, bolts, nuts, cotter pins, etc., may be
used provided they possess suitable properties and are replaceable by the AN or JAN Standard
parts without alteration, and provided the corresponding AN or JAN part numbers are refer-
enced in the parts list and, if practicable, on the contractor's drawings.  In the event
there is no suitable corresponding AN or JAN Standard part in effect on date of invita-
tion for bids, commercial parts maybe used provided they conform to all requirements of
this specification.
3.2 Purpose,-  The bomb shackle covered by this specification shall be capable of
suspending and releasing any one U. S. Navy or Amy-Navy bomb or mine of a nominal weight
between and including 100 lb and 2,000 lb and equipped with two suspension lugs spaced
14 inches center to center.  The shackle is designed for use in both dive and horizontal
bombing, and its performance shall comply with the requirements of the most severe appli-
cable conditions listed in Specification MIL-T-7743(Aer)} except as otherwise noted
therein.  The shackle may be actuated electrically by a bomb shackle release or by the
manual release system of the airplane, and has provisions for easy latching, and safe
locking when suspended or mounted, either externally, as from an airplane wing or fuselage,
or internally as within a bomb-baye
Interchangeability.-  All parts shall be capable
of
interchangeable assembly,
3.3
except such parts as are permanently joined to other parts,
as
by riveting, or welding,
in which case the unit thus formed by the permanent joining
of
parts shall be inter-
changeable with all other like units.  Jigs and gages shall
be
provided by the contractor
for use, where necessary to insure such interchangeability.
3.4 Conformance with Drawings and Specifications.- All component parts shall.be in
strict conformity with the applicabl e approved drawings and material specifications listed
in paragraph 2.1.3.  No departures from the tolerance shown on the drawings or specifica-
tions shall be permitted without prior approval by the procuring agency. Manfacturing
processes and finishes shall be as shown unless otherwise approved. (See paragraph 6.1.)
3.5 Workmanship.-  The workmanship shall be that required by the best commercial
practice covering this type of equipment, for the quantity production of analogous parts.
All operating parts of the shackle shall have a smooth workmanlike finish, free from
flaws, ragged edges, or tool marks.  The exterior shall have a smooth finish with all
burrs removed.
SAMPLING, INSPECTION, AND TEST PROCEDURES
4.
The inspection and testing of bomb shackles shall
4.1 Classification of Tests.-
be classified as follows:
(a)
Preproduction tests:  Preproduction tests are those tests
accomplished on samples which are representative of the
production of the item after the award of contract. to
determine that the production meets the requirements of
this specification.
(b)
Inspection tests:  Inspection tests are those tests
accomplished on bomb shackles manufactured and submitted
for acceptance under contract.
