) waren und somit der Heli angefangen hat zu wackeln. Als es dann zu heftig wurde verringerten sie die Drehzahl, das Wackeln wurde aber sogar noch heftiger und dann ham se die 'notbremse' gezogen (wie onkel manuel schon sagte). Dann lockerte sich schon der hintere Turm und die Rotorblätter stießen anernander und der Turm brach ganz ab.

Ground Resonance:
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.
