5) Local distortion on the leading edge is permitted with these limits: (Figure606)

a) Not more than two locations and the circumferential dimension (Dim.Q) is not more than 0.4 inch (10.0 mm).

b) The depth (Dim.M) into the blade chord is at least six times greater than the circumferential dimension (Dim. Q).

So 7mm X 6 = 42mm. As damage extends over 60mm - within limits
