The preventive maintenance and inspection checks are
listed and defined in the following table. This table is
divided into two basic parts, the “AREA” to be inspected
and the “INTERVAL” at which the inspection is to take

systems along with the components that make up that
system are listed. The “INTERVAL” portion of the table is
divided into five columns representing the various inspec-
tion time periods. The numbers listed within the interval
column represent the applicable inspection code for
