Which type of POA is not authorized for use with the CH-46A/D/E?

The type of Point of Attachment (POA) that is not authorized for use with the CH-46A/D/E is the Nylon Single POA. This designation is based on the specific materials and construction requirements established for the safe and effective operation of the helicopter. The CH-46A/D/E models are designed to utilize other types of POAs that can bear the loads and stresses encountered during sling load operations more effectively.

Nylon POAs are generally less durable under certain environmental conditions, especially when exposed to the elements such as extreme temperatures or UV light, which can lead to degradation over time. The metal, fiber, and composite POAs have been selected for their higher strength and reliability, as they can endure the rigors of sling load operations, ensuring safety and performance. These alternatives have been tested to meet the necessary load requirements without compromising the integrity of the helicopter's operational capabilities.
