2.2.4 JACE Condition Codes: A defect is measured by comparing the normal cross-section-
al area of an individual element with the depth and length affected because of scratches, nicks, gouges,
holes, dents, or corrosion. Regardless of the type of defect, the amount of material loss is identified as
defect reduction. Any defect reduction will affect the strength of the part.
CODE
DEFECT CRITERIA
CONDITION
Worn Excessively
A
Report wear that has proceeded to more than half of the material
thickness. For stainless steel wear strips, report wear through.
Buckled
B
Sheetmetal that has been warped, kinked, or deformed by an exter-
nal force. Creasing due to oil-canning that does not return on its
own or that is transmitted into adjoining pockets.
Deteriorated
C
General degradation of non-metals that result in a change of texture,
consistency, shape, color, etc., and that reduces the functionality of
the item.
Corroded
D
Corrosion of any type that requires repair beyond "Clean and Treat"
exceeds minor classification. See Appendix E.
Cracked
E
Cracks of any length exceed minor limits.
Binding
F
Any tight or resistive reaction betwee two moving surfaces due to
deterioriated rollers or bushings or alignment.
Loose Fasteners
G
Any loose fasteners, report the total number of fasteners retaining
the fixture or panel followed by the number of loose fasteners in the
remarks section of the JACE Checklist.
Missing Fasteners
H
Any missing fasteners, report the total number of fasteners retaining
the fixture or panel followed by the number of missing fasteners in
the remarks section of the JACE Checklist.
Broken
I
Any break exceeds minor limits.
Punctured
J
Any unauthorized hole is reportable as a puncture.
Chafing
K
Any stationary fixtures or panels rubbing against the other usually
identified by a powdery substance around the panel or the fixture
edges. Usually the paint or the sealant is worn through.
Oversize Holes
L
Any wear that has caused the holes to enlarge beyond repairable
limits.
Security
P
Any condition where an item is not tightly connected to the attaching
structure properly.
No Defect
R
If an indicator does not have a defect, circle the R to indicate the
indicator was inspected.
Dented
U
Any dent that exceeds 10 percent of thickness or width or length that
exceeds 2.5 times the material thickness is a major defect.
Scratched/Nicked
X
Any scratch that exceeds 10 percent of thickness or length exceeds
2.5 times the material thickness is a major defect.
Interim Repair
Y
Interim repair or nonstandard repair not authorized in existing techni-
cal data.
