A malfunction is the failure of a part or
assembly of the gun to perform the
operation it is designed for. A malfunction
will result in a stoppage, or failure of
the gun mechanism to perform its function
when operated. Thus, the failure to extract
a fired shell may be termed a malfunction
and the consequent blocking of the barrel
chamber preventing the loading of a live
shell may be termed a stoppage. Such a
stoppage may be due to a malfunction of the
mechanism or faulty ammunition such as
rupture of a shell.
Immediate action is the term applied to the
automatic application of a predetermined
method of relieving the stoppage and thus
putting the gun in action as soon as
possible.
Stoppages due to improper operation of the
gun or faulty ammunition may, as a rule, be
quickly relieved through immediate action.
Stoppages caused by malfunction of parts
due to_wear, breakage, or improper
assembly, cannot as a rule be immediately
relieved and to such immediate action does
not apply. Both types of stoppages will be
covered herein. The failure, its probable
cause, and suggested correction will be
tabulated in order. Other stoppages may
occur and should be dealt with by analyzing
their cause and, if possible, correcting
it. A thorough understanding of the propery
assembly, operation, and mechanical
functioning of the gun is essential in
determining the cause of malfunctions and
stoppages.
