Fan blade masking/coating check inspection tool

A method of using a masking/coating check inspection tool for inspecting a root masking/coating edge on a root end of a fan blade, the masking/coating check inspection tool comprising:

• an elongate planar base having a first end, second end, bottom surface, top face, length, width, and thickness, the first and second ends distal from each other and the length greater than the width;
• a pillar disposed between the first end and the second end, perpendicular to the elongate planar base and projecting upward from the top face, the pillar having a first end datum;
• and
• a first masking/coating check tolerance band disposed adjacent to the first end, configured to provide a pass/fail indication of a first masking/coating edge with respect to the first end datum;
• the method comprising the steps of:
• (a) placing the first end in position on the root end, wherein the first end datum contacts the root end;
• (b) viewing the root masking/coating edge relative to the first masking/coating check tolerance band;
• (c) evaluating whether the root masking/coating edge is within the first masking/coating check tolerance band;
• (d) indicating an favorable result if the root masking/coating edge is within the first masking/coating check tolerance band;
• and
• (e) indicating an unfavorable result if the root masking/coating edge is not within the first masking/coating check tolerance band.

A method of using a masking/coating check inspection tool for inspecting a platform masking/coating edge on a platform edge of a fan blade, the masking/coating check inspection tool comprising:

• an elongate planar base having a first end, second end, bottom surface, top face, length, width, and thickness, the first and second ends distal from each other and the length greater than the width;
• a pillar disposed between the first end and the second end, perpendicular to the elongate planar base and projecting upward from the top face, the pillar having a first end datum;
• a second masking/coating check tolerance band disposed adjacent to the second end, configured to provide a pass/fail indication of a second masking/coating edge with respect to the second end datum;
• the method comprising the steps of:
• (a) placing the second end in position on a first region of the platform edge, wherein the second end datum contacts the platform edge;
• (b) viewing the platform masking/coating edge relative to the second masking/coating check tolerance band;
• (c) evaluating whether the platform masking/coating edge is within the second masking/coating check tolerance band;
• (d) indicating an unfavorable result if the platform masking/coating edge is not within the second masking/coating check tolerance band;
• (e) indicating a favorable result if the platform masking/coating edge is within the second masking/coating check tolerance band;
• (f) placing the second end in position on a next region of the platform edge, wherein the second end datum contacts the platform edge;
• and
• (g) repeating steps (b) through (f) as necessary.
