Poly-Brush
Poly-Spray
Flat Rib Lace Cord
LOCTITE Depend 330 Adhesive

(2) INSPECTION OF FABRIC

The polyester fabric used is very durable and its longevity depends on maintaining the
coating in good shape. Ultraviolet radiation (in other words, direct sunlight) is the main
cause of deterioration of the fabric. The fabric is treated at the factory to protect it from
this type of radiation.
The fabric covering meets the requirements of TSO C-15d/AMS which stipulates that
the minimum breaking strength of the fabric should be at least 56 lbs. Testing fabric
requires skill and experience and should only be performed by a qualified person who
has experience in this matter.
The aircraft has been covered using a process that is proprietary to Cub Crafters. It is
similar to the Poly-Fiber Aircraft coating process, more commonly referred to as the Stits
method.
(3) FABRIC REPAIRS
The decision to repair damage on the fabric or whether to replace the covering on the
part will depend upon the extent of the damage and should take into account the
aesthetics of the repair. These repairs require the use of an iron to shrink the fabric. It is
very important that only a good quality clothing iron be used.
