ABSTRACT:
A method and apparatus for detecting defects in a structure formed of a honeycomb matrix bonded to a support surface including providing a probe body including means defining a fluid passage forming a supply port to an exterior surface of the probe body; connecting a pressurized fluid source to the fluid passage at a location distal from the supply port; placing the supply port in close proximity to a cell of the honeycomb matrix; supplying fluid from the compressed fluid source to the cell via the fluid passage; and monitoring a fluid pressure produced at a portion of the honeycomb matrix adjacent to the supply port to detect disbonds between the honeycomb matrix and support surface.
