Chinook CH-47 Helicopter Destruction Due to Ground Resonance |

The Chinook CH-47's destruction was caused by ground resonance, which is a dangerous condition that can occur any time the helicopter rotor or autogyro rotates while the aircraft is on the ground. Similar in concept to the behavior of a washing machine when clothing is concentrated at one point during the spin cycle, ground resonance can occur with a rotorcraft when the spacing between blades becomes irregular or a damping system, including drag hinge dampers, landing gear oleo struts, or wheel tire pressure, operates. beyond the limits.
