INSPECTION REQUIREMENTS AND OVERHAUL
3.1
INSPECTION REQUIREMENTS
3.2
GENERAL REQUIREMENTS
a.
Inspection of the IBF system consists of, in general terms, inspection of the filter assembly,
inspection of the structural components, inspection of electrical and system components, and a
special inspection at three specified points based on hours after initial installation. The
components of the system are divided, generally as a scope of work, into Filter Assembly, Seal,
Structural Components, and Systems and Electrical components as is done throughout the
manual.
b.
Refer to Appendix A - Illustrated Parts Breakdown for component illustrations that provide
supplemental information relative to proper assembly configuration, orientation, and locations
for all components to be inspected per Chapter 3 and Table 1. Refer to Appendix A, Figure A-1
for the primary kit components. Refer to Figures A-2 through A-9 for structural details. Refer to
Figure A-12 for electrical components.
c.
Table 1 gives a recommended inspection schedule for the components of the system. The
Trouble-Shooting Guide, Table 3 found near the end of Chapter 8, also gives additional
guidance when performing inspections and encountering trouble with the system. Chapter 8 also
provides specific inspection guidance and removal/installation procedures for each component
and is structured in the same three major groups as discussed above.
3.2.1
FILTER ASSEMBLY INSPECTION
a.
The following inspections pertain to the barrier filter assembly and associated components,
which include the filter assembly (i.e. filter frame and filter media) and all associated
seals/fasteners.
b.
ON-CONDITION: Any FMA indication in the “RED”, “FILTER” light indication of the IBF
cockpit indicator or failed PAC requires a visual inspection in accordance with Chapter 8.
c.
VISUAL: All filter assembly components are to be visually inspected at every annual inspection
in accordance with Table 1 checking for the following: filter media for tears, punctures, uneven
or damaged pleats; seals for tears/damage; frame components for corrosion, cracks, distortions
near holes, and check for missing or damaged fasteners.
