The United States Coast Guard USCG operates a fleet of H-65 Dolphin aircraft. Support for the H-65 fleet is provided by the USCG Aviation Logistics Center in Elizabeth City, NC. The Aircraft Ship Integrated Secure and Traverse ASIST system has been installed on the USCG National Security Cutter. The ASIST system is used to secure aircraft to the NSC as well as move the aircraft from the landing pad. The ASIST system includes two components that may affect ground resonance characteristics of the aircraft A retractable probe that extends from the bottom of the aircraft, and a Rapid Securing Device ground handling system that captures the probe and moves the aircraft off of the helicopter pad. The ALC has been tasked with outfitting one H-65 aircraft with a prototype ASIST system for an operational evaluation of the system on the NSC. Prior to testing on an NSC, an evaluation of the effects of the ASIST system on ground resonance is desired. This report documents the results of risk mitigation testing to evaluate potential ground resonance effects and structural loading of the ASIST probe.
