A barrel-roll in a chinook has to be interesting indeed!

One of the disadvantages of a fully articulated rotor system, such as that found on the CH-47 Chinook helicopter, is the susceptibility to ground resonance. Items to consider in limiting the chances of encountering ground resonance include ensuring that all tires are inflated to 88 psi and all landing gear struts and blade dampeners are properly serviced. The two videos below show the result of a Chinook helicopter falling victim to ground resonance. The tail number was 84-24156, and was the one that previously encountered uncommanded flight control inputs which resulted in the aircraft performing a barrel roll. After the roll incident, the aircraft was assigned to Aberdeen Proving Grounds in Maryland, and was utilized as a ground test device.
