Condition Maximum Serviceable Limit
Radial cracks out of the gill holes Permitted.
Other cracks Permitted, if no more than two cracks connect at one point.
Burns or spalls (no holes through the basic metal) Permitted.
Cracks in the fillet area adjacent to the inner and the outer
platforms
Permitted.
Burns and erosion Permitted, if the damaged area is less than 0.1 square inch
