A helicopter-manufacturer contacted us with a vibration issue. After trial runs of a serial helicopter, the pilots complained of a high level of vertical vibration in all flight modes.
After the helicopter had been assembled, it underwent the standard procedures of blade tracking and main rotor dynamic balancing. However, the crew still experienced a very uncomfortable level of vibration.
