What is the consequence of using a fabric that is no longer available?

Using a fabric that is no longer available results in difficulty in obtaining replacements. When a specific fabric is out of production or has been discontinued, sourcing exact matches can become a significant challenge. This situation can lead to multiple issues for aircraft maintenance and repair.

For instance, if damage occurs to the fabric covering of the aircraft, finding a replacement that matches both the specifications and the physical properties of the original fabric may not be possible. This could lead to the use of substitute fabrics that might not possess the same characteristics in terms of strength, weight, or durability, which can adversely affect the overall integrity of the aircraft covering.

Additionally, discrepancy in fabric characteristics can complicate maintenance procedures and impact the overall longevity and safety of the aircraft. Therefore, the main consequence is the operational difficulty in obtaining replacements for the discontinued fabric.
