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