Fungus resistance in aircraft materials and equipment is essential for several reasons, and there are specific needs associated with ensuring such resistance. Here are some key points:

1. Material Integrity: Fungus can degrade materials, leading to structural weaknesses. Aircraft materials such as plastics and textiles are particularly vulnerable. Ensuring fungus resistance helps maintain the longevity and reliability of these materials.

2. Performance and Safety: Fungal contamination can lead to performance issues in equipment and compromise safety. For instance, the degradation caused by fungi can affect the operation of electrical and electronic systems within the aircraft.

3. Environmental Conditions: Aircraft are often exposed to environments conducive to fungal growth, including high humidity, warm atmosphere, and the presence of inorganic salts. Materials need to withstand these conditions to prevent fungi from thriving.

4. Certification Requirements: The Federal Aviation Administration (FAA) has specific certification requirements concerning fungus testing for aircraft components. These involve testing the materials under conditions favorable for fungal growth to ensure their resistance (source).

5. Test Methods: Resistance to fungus is evaluated through tests such as the RTCA DO-160 and MIL-STD-810 Method 508. These tests determine whether equipment and materials are adversely affected by fungi and ensure that they meet the required standards (source).

6. Health Risks: Fungal growth on aircraft can pose health risks by serving as a breeding ground for potentially hazardous microorganisms. This is especially important in the aircraft interiors where passengers and crew are directly exposed (source).
