Which factor is crucial for the longevity of fabric used in aircraft covering?

Maintenance procedures are crucial for the longevity of fabric used in aircraft covering because they directly affect the fabric's condition and performance over time. Regular maintenance checks, cleaning, and addressing any damage promptly can significantly extend the life of the fabric. This includes examining for signs of wear, UV damage, or deterioration due to environmental factors. Maintenance also encompasses ensuring proper tension and securing methods, which are vital for preventing fabric sagging or failure during flight.

While color selection, thickness of the fabric, and type of stitching can influence other attributes such as weight, aesthetics, or initial durability, they do not have the same direct and ongoing impact on the fabric’s longevity as proper maintenance does. Regularly servicing the fabric helps to ensure it remains functional and safe for use, making maintenance the key factor in extending the lifespan of aircraft covering.
