ThicknessTool kit is now referenced in the A330 NTM
Thickness Tool was developed by TESTIA to speed-up the thickness measurement of aluminum alloy panels with thickness between 2 mm (0.079 in) and 20 mm (0.0787 in) after the removal of damage (e.g. corroded areas) on A320 (e.g. wing skin panels, fuselage panels etc.). Its applicability is now extended to A330 thanks to the procedure 51-10-04B.
