maintenance and repair. An example of a
maintenance manual is the Technical Manual for
Description, Operation, and Maintenance of the JP-5
Jet Fuel Centrifugal Purifier, NAVSEA S9542-AB-
MMO-010 (fig. 8-2).
By proper use of these publications, all
equipment can be operated and maintained in the
same efficient manner throughout the Navy.
Technical/Maintenance manuals do not contain
detailed descriptions or procedures concerning pre-
ventive maintenance, since this information is con-
tained on maintenance requirement cards (MRCs).

Senior petty officers must be able to interpret
technical publications and to supervise their use. The
senior ABF also must know how to obtain technical
publications and how to keep them up-to-date.
Many technical publications issued by the Naval
Air Systems Command are of interest to the ABF.
The General Information and Servicing section of the
Maintenance Instructions Manual for each type of
aircraft covers the required procedures for refueling
the aircraft. Mobile refuelers and aircraft-handling
equipment are covered by other Naval Air Systems
Technical publications issued by the Naval Sea
Systems Command cover most of the shipboard equip-
ment used by the ABF. The fuel system for each ship
is covered in a Ships Information Book (SIB), The
SIB for the ship to which the ABF is attached should
be studied thoroughly. Also, each major component is
covered by a Technical/Maintenance Manual issued
by the Naval Sea Systems Command.
INSTRUCTIONS AND NOTICES
The Navy Directives System is used throughout
the Navy for the issuance of nontechnical directive-
type releases. These directives establish policy, or-
ganization, methods, or procedures. They require
action to be taken or contain information affecting

uniform plan for issuing and maintaining directives.
Conformance to the system is required of all bureaus,
offices, activities, and commands of the Navy.
