Bombsight Log
is an official history of
bombsight from the time of its manufacture
until it is withdrawn from service for survey.
It
is an official document and must be treated
with
the same
care of making entries as any other log
book.
All entries except classroom
instruction
will
be sioned by a sM officer.
The log book is self-explanatory so far as
entries are
concerned
and no difficulty should
be experienced
in keeping it.
It has been found
from examination of log books which have been
turned in with instruments for repair and overhaul
that:
(a) A great deal of work is done on bomb-
sights which is not entered in the log.
(b) Considerable
upkeep work is performed by
inexperienced personnel.
(c) There is a tendency to do more disass-
embly and adjustment than is necessary.
In order that the overhaul personnel may have
a full knowledge of the condition of the
equipment
it is of the
utmost importance that every adjust-
ment or casualty be
recorded clearly and fully in
that log.
It is only by cataloguing the frequency
of casualties and adjustments that it is possible
for personnel charged with design to have an in-
dication of desired or necessary changes
able to take steps to correct
current designs, or
instructions.
Whenever a bombsight is withdrawn from
service and turned in to the Supply Officer for
storage or shipment,
a notation will be made by
