TM l-1500-328-23
Scheduled Preventive and Phase Maintenance Inspections.
a. These inspections are due at predetermined flying hour or
calendar intervals.
They provide for systematic examination of the
aircraft, and associated equipment at specified intervals during their
service life.
The intervals for scheduled maintenance inspections are
published in the applicable aircraft maintenance TM or phase
maintenance checklist.
Planning and scheduling will be used to
maximize use of available flying hours and make sure the inspection
intervals are not exceeded.
b . Most
for standard aircraft (aircraft identified in AR
700-138) include a series of preventive maintenance checklists.
The
checklists assist maintenance personnel by organizing required tasks
in an easy to follow sequence.
The checklist is an extension of the
aircraft -23 TM.
If a checklist has not been developed for a specific
type or model aircraft, the inspection and servicing instructions are
included in the -23 TM.
C.
Aircraft that are classified as non-standard aircraft (aircraft
not identified in AR 700-138) will be inspected and maintained as
follows:
(1) Standard aircraft that have been reclassified to non-standard
will be inspected and maintained using the original
and
maintenance procedures.
(2) Aircraft gained from other United States military services
(Air Force, Navy, or Marines) will be inspected and maintained using
the manuals and methods of the other military service.
(3) Aircraft that are "civilian in nature," extensively modified,
or in development evaluation, seldom have established military
maintenance procedures.
These aircraft will be inspected and
maintained using the manufacturer's maintenance instructions and
All actions shall be documented per DA Pamphlet 738-751,
manuals.
unless specifically directed by AMCOM to be documented per Federal
Aviation Regulations (FAR), and Federal Aviation Administration (FAA)
policies.
Phase Maintenance Inspection Method.
a. This system includes two inspection elements, the Phase
Maintenance Inspection (PM) and a Preventive Maintenance Daily (PMD)
or a Preventive Maintenance Service (PMS).
It provides a methodical
examination of the aircraft and associated equipment.
Requirements
for these inspections are in the applicable PMD, PMS and PM inspection
checklists.
