Eurocopter has received reports of failure of the mounting base of the CPT 609 crash position transmitter beacon antenna. The failures have been determined to be caused by vibration. Failure of the antenna will significantly reduce the radiated power of the crash position transmitter and loss of the antenna during flight may jeopardize the safety of persons on the ground.
