Find cracks beneath the bushing at MLG Axle B737

Dears

Please help me! I have a problem to find an initial cracks beneath the bushing(CRES material) & the material to be inspected is Steel. How is the technik to inspect that material if bushing still installed?
Could you find the Pitting Corrosion use that technik?

Ruly,

I believe you most reliable source of information would be Boeing.

From my past experience (B737 especially), Boeing will always issue the technique, give you the probe number and manufacturer as well as the test pieces to do your job. This inspection most likely originated from and AD (Airworthiness Directive) issued by the FAA or from a Service Bulletin issued from Boeing. You should have access to all this information. If you are doing the work on behalf of someone else, your customer should have all this information available.

Extended Range Variable Wall® Piping Calibration Blocks for Longseam Inspection

es place circumferentially or “around the curve” for applications such as inspection of longseam welds in piping and vessels. Jointly designed by PH Tool and Holloway NDT, the blocks feature side-drilled hole reflectors positioned within novel compound-curves, each with multiple thickness steps. The unique design results in a light and compact form factor, with the largest block weighing just over 15 lbs and spanning just 16 ¾”. Coverage is provided for nominal pipe sizes from 6” to 10” in the small block and 12” to a whopping 56” in the large block. The compound OD curves and multiple wall thicknesses actually exceed ASME requirements, providing exceptional signal response and measurement accuracy. Properly managing beam divergence off the ID and stabilizing beam skew due to probe rocking is essential to maintaining a consistent calibration when inspecting lengthwise on curved surfaces.
