What is the largest hole that may be repaired with a fabric patch?

In aviation, particularly in the context of repairing composite and wooden structures, the size of the hole that can be effectively repaired with a fabric patch is critical for maintaining structural integrity and safety. A fabric patch is generally used for small repairs, where loss of material needs to be mitigated without significant reinforcements.

In this case, if the maximum diameter for a hole that can be patched with fabric is stated as 1 inch, this aligns with industry standards for small surface repairs. Holes larger than this would typically require more significant repairs, such as inserts or other forms of structural reinforcement, as they could compromise the strength and durability of the airframe.

Using a larger patch could lead to issues such as inadequate bonding or failure under stress, which is why the specified diameter limit is important in aviation maintenance practices.
