| Abstract: | Determination of detectable flaw size is the requirement for establishing maintenance plan, and it is an important basis for analyzing the damage tolerance and durability. An inspection approach of the wing beam structure with screws connected is studied. The curve is obtained for inspection probability with ultrasonic detecting cracks. |
