What should NOT be used to attach loads to the CH-46 A/D/E if there is a specific condition present?

The choice of nylon as unsuitable for attaching loads to the CH-46 A/D/E under certain conditions is rooted in the material's properties and potential limitations in specific environments. Nylon, while strong and versatile, can absorb water, leading to a reduction in its strength when wet. Additionally, it has a higher risk of failure when exposed to ultraviolet (UV) light over time, which can also degrade its integrity. In scenarios where moisture or prolonged exposure to sunlight is present, nylon may not be reliable enough for secure load attachment.

For critical load-carrying applications like sling loading with helicopters, materials must maintain their strength and performance under varying environmental conditions. Therefore, understanding the circumstances in which nylon might compromise safety and efficacy is key for proper operational planning and ensuring secure load management on the CH-46 A/D/E.
