What risk does moisture pose to fabric covering in aircraft?

Moisture poses a significant risk to fabric covering in aircraft as it leads to fabric degradation. Over time, exposure to moisture can cause the fabric to weaken, lose its structural integrity, and break down. This deterioration can result in reduced strength and potential failure of the covering, compromising the safety of the aircraft. In addition, moisture can promote the growth of mold and mildew, further damaging the fabric and potentially leading to corrosion of the underlying structures. Proper maintenance and attention to moisture exposure are essential to ensure the longevity and safety of aircraft fabric coverings.
