Abstract
A masking and coating check inspection tool for inspecting a masking and/or coating edge on a fan blade includes an elongate planar base having distal first and second ends, bottom surface, top face, length, width, and thickness. The length is greater than the width. A pillar perpendicular to the elongate planar base and projecting upward from the top face between the first and second ends has a first end datum, and a first masking check tolerance band disposed on the first end, configured to provide a pass/fail indication of the first masking edge with respect to the first end datum. The pillar can have second end datum and second masking check tolerance band on the second end configured to provide a pass/fail indication of a second masking edge with respect to the second end datum. The inspection tool can be used on root and platform masking/coating edges.
