摘要：
The paper contains results of experimental research carried out helicopter bench. Helicopter test bench was used to develop defect localization methodology of helicopter structure fatigue damage technical diagnostics. Analysing helicopter structural defects for different helicopters types it is concluded that the joint elements of helicopter tail boom are still exposed to fatigue crack formation, crack development process is not controlled, and sometimes it is not possible to detect defects at all.
