PAINTING, SEALING, CORROSION PREVENTIVE
COMPOUND APPLICATION
3.1 GENERAL.
Operators may need to wear respiratory protective equipment
when spray painting, or the area may need proper exhaust
ventilation. USAF organizations that apply protective coatings
will request initial and annual surveys by the local Bioenvironmental
Engineer and Safety Officer. Their recommendations
for complying with Air Force Occupational Safety and Health
Standards (AFOSH) will be followed. Contractor personnel
will comply with all Bioenvironmental Engineer, Safety Officer
guidelines and Occupational Safety and Health Administration
(OSHA) Standards.
3.2 DEFINITION OF EXPOSURE.
Exposure is defined as SE that is subjected to combined direct
action of climatic elements (to include the interior of such
units). Climatic elements include temperature extremes,
humidity extremes, rain, hail, snow, sleet, salt-laden air, industrial
atmospheres, direct solar radiation, dust and scouring
action of wind-blown sand.
3.3 REQUIREMENTS FOR PAINTING - FIELD LEVEL.
NOTE
Flight Chiefs/Superintendents are authorized to make
the determination if the unit requires complete repainting.
SE shall be repainted when painted surfaces have become bare
or exposed because of paint deterioration or damage, or when
it is determined that the equipment is inadequately protected
from corrosion. Repainting of SE for purely cosmetic reasons
is prohibited. SE units will be prioritized through the work
flow on a “worst first” basis as determined by SE Scoring
documentation. Refer to Table 3-1.1 for SE scoring guidance.
3.3.1 Corrosion Control Scoring Program and Complete
Repainting Criteria. SE requires a robust corrosion program
to ensure the longevity of the equipment. A system of scoring,
prioritizing and scheduling will assist with preservation and
refurbishment.
3.3.1.1 Corrosion Scoring. The SE corrosion condition
will be scored annually during periodic scheduled maintenance
inspection. This allows prioritization and scheduling
with the appropriate corrosion control facility. The SE will be
prioritized and scheduled on a “worse first” basis. The SE
owning work center will develop a tracking system to annotate
the scores using categories 1-4 as described in Table 3-1.1.
Scoring sheet examples can be viewed on AFCPCO Portal
Website.
3.3.1.1.1 SE will be evaluated to determine an accurate corrosion
score. The minimum areas evaluated for deterioration
and corrosion are:
• Panels or component surfaces.
• Framework, sub-frame, chassis, and axles.
• Panel or component edges.
• Welds and spot welded panel seams.
• Fasteners and latches.
• Attachment points.
Deterioration involves:
• Chipped, peeled or blistered paint on panel surface.
• Visible corrosion (rust, pits, white powdery deposits or
rust leaching from panel seams).
• Cracked coating around welds or fastener heads.
• Cracked, peeled or discolored paint at panel seams.
• Cracked or peeled coating at attachment points.
• Coating deterioration caused by environmental agents,
ultraviolet light, corrosive fluids as evidenced by excessive
fading or a chalky residue on panel surfaces.
• Missing coatings over recent weld repairs.
3.3.1.2 Scoring Categories. In order to set the priority of
scored equipment, technicians evaluate the unit and place in
one of four categories (Table 3-1.1) with category 1 being
best, requiring no touch-up and category 4 as worst, requiring
extensive disassembly, repair, and refurbishment. Leadership
should utilize this tool to determine the priority for induction
of “worst first” into the refurbishment workflow.
