What is the purpose of a patch on a damaged canopy and what are general patching steps?

• A. To reinforce tears or worn areas; cut a patch, edge-finish, align, and sew or bond per standard.
• B. To change color of canopy.
• C. To reduce weight by trimming fabric.
• D. To decorate with decorative stitching.

Answer: (A)

When a canopy is damaged, the patch is used to reinforce the damaged area so the fabric can carry the intended load without the tear spreading. A properly applied patch restores strength and helps maintain airworthiness, rather than just masking the damage or altering appearance.

The general patching steps reflect this purpose: cut a patch from compatible canopy fabric that is larger than the damaged region, edge-finish the patch to prevent fraying, align the patch so the fabric grain and load direction are consistent with the canopy, and then secure it by sewing or bonding according to the standard procedures. Following the approved method ensures the repair has the required strength and durability.

Other options don’t address structural repair: changing color, trimming fabric to shed weight, or decorative stitching do not reinforce the damaged area or meet maintenance standards.
