What is a common cause of mold growth on fabric covering?

Prolonged exposure to high humidity is a well-known contributor to mold growth on fabric covering. High humidity creates an environment with increased moisture levels, which is conducive to the development of mold, mildew, and other fungi. Fabric that is not properly dried after washing or exposure to moisture, coupled with high humidity environments, becomes a breeding ground for these organisms.

In the context of aircraft maintenance, ensuring that fabric coverings are protected from high humidity is critical. This can involve using proper storage methods, ensuring adequate ventilation, and monitoring moisture levels in the aircraft’s storage or hangar environment. In contrast, direct sunlight exposure typically helps in drying fabrics and reducing moisture levels, while frequent use of the aircraft may promote better drying through airflow and temperature changes. Low air pressure inside the cabin generally does not contribute to mold growth but can affect other aspects of aircraft operation.
