A method of inspecting the wear of a turbine engine part includes, by means of a calculator: a reference plane is defined; by measuring said part to be inspected, a modelling of at least a portion of said part is acquired in the form of a three-dimensional inspection grid; the three-dimensional inspection grid is inspected with the reference plane, using a dedicated algorithm using a projection of points (10; 10.1, 10.2, . . . , 10.n); if the result of the comparison is included in a predetermined tolerance range, the part is defined as compliant; otherwise, the part is non-compliant.
