The Importance of Aircraft Paint and
Coatings in Aircraft Appraisals
Paint is not just skin deep, it is a plane’s first layer
of defense against the elements. It provides
protection for the aluminum or composite
structure from corrosion, bugs, rain and the sun.
The condition of aircraaft paint is not only a direct
reflection of how well protected the exterior of the
plane is, it also provides an element of confidence
to future buyers about the overall maintenance of
the aircraft inside and out. aircraft appraiser
A fresh high quality paint application not only adds
an aesthetic appeal to an aircraft exterior, it can in
some instances also increase the value of the
aircraft. In most cases the value added to the
aircraft is actually more than the cost of repainting
the aircraft, making painting an aircraft one of the
single best investment upgrades.
The following ratings are utilized by our aircraft
appraiser during the accomplishment of a
National Aircraft Appraisers Association (NAAA)
certified appraisal. It is extremely rare for most
aircraft to earn a 10 Rating.
#10 Rating:
Condition of the exterior paint is flawless. External
painted surfaces have a deep, rich, wet look. There
is no pooling, sagging, running, orange peeling,
thin areas or over-spray on any painted surfaces.
Stripes and numerals are well defined with crisp
lines and no irregularities. The paint is of high
quality. If a re-paint, all surfaces have been
stripped and prepared properly and consistent
with the paint manufacturers recommended
application procedures. The age of the paint is two
years old, or less.
#9 Rating:
Exterior painted surfaces are almost flawless. In
almost every aspect the painted surfaces would
meet the #10 rating criteria except for minor
exceptions. The paint may be over two years old
but less than 5 years old if the aircraft is tied down
outside or 10 years if old if the aircraft is stored
under cover. There may be a very small amount of
dust particles in the paint. There may be a few
chips in the paint under the fuselage from props
slinging pebbles. Paint looks like new and the
above discrepancies are only discernible upon
very close inspection.
#8 Rating:
Paint has a wet look with a few chipped areas
under wings, fuselage and empennage. Leading
edges may show first stages of abrasion wear but
overall the paint is in very good condition and
shows very well within 20 feet.
#7 Rating:
Paint has a good shine with some abrasion wear
on leading surfaces but still retaining good
coverage. Repainted surfaces or touched up areas
are not noticeable. The paint may be new with a
limited amount of orange peel, pooling, sags or
over-spray. However, painted surfaces are well
protected and the aircraft has good eye appear.
#6 Rating:
Paint is beginning to oxidize with evident abrasion
wear on leading edges. Paint is in need of a good
cleaning and waxing to give it a semi-gloss
appearance. If recently painted, there may be
pooling, sagging, running or orange peeling and/or
significant amount of foreign particles in paint.
Accent trim may be of poor quality, but paint
overall would be adhering well to surfaces. Overall
appearance within 30 feet is fair to good.
#5 Rating:
Paint is oxidizing and there may be numerous
areas of chipping on lower surfaces of aircraft.
Leading edges show significant signs of abrasion
wear, but are protected by paint. Surface
corrosion may be apparent on the airframe and
will affect paint because the painted surface must
be stripped in order to treat the corrosion. Overall
appearance is fair within 30 feet.
#4 Rating:
Consistent with all of the characteristics of #5
rating except the aircraft will soon need repainting.
Overall appearance is poor to fair and
cleaning/waxing will not significantly improve the
appearance or protection of the aircraft surfaces.
#3 Rating:
Paint is poor quality, oxidized and shows excessive
wear on leading edges and control surfaces. Many
chips and scratches are apparent and overall the
aircraft needs painting. However, the paint is
protecting the aircraft surfaces, but looks poor.
#2 Rating:
Aircraft needs painting. No good points.
#1 Rating:
Aircraft needs painting, and additional preparation
of the aircraft surfaces is required before painting.
Generally consistent with aircraft having extensive
corrosion on surfaces.
