This is a highly improved and metrologically corrected tool used to inspect the static port flushness requirements of Gulfstream G150/G200/G280 and likely G100 series aircraft as referenced in CMP 34-11-10, Geometric Inspection Gaging Equipment GSE3420082 Ref: 341204. It has been thoughtfully improved to correctly place the mass of gaging force over the centerline of the reference anvil rather than asymmetrically as is in the original tool. The result is radically enhanced accuracy and repeatability as well as greater handling flexibility. It includes a new Mitutoyo 1961T indicator with its factory Certificate of Inspection and a calibration gage.

These now include a balanced scale dial indicator (not pictured) that makes reading much easier.
