Patent ID: 8060232

Claim:
A method for installing an insert in a structure, comprising: positioning the insert within an insert aperture of the structure; injecting a potting compound into the insert aperture through a first fill hole of a plurality of fill holes externally accessible on an exterior surface of the insert until the potting compound exits the insert aperture via a second fill hole of the plurality of fill holes; and determining whether the insert is properly installed utilizing a mechanical impedance instrument that applies a vibration to the insert at a pre-determined frequency and measures a response frequency by inserting an impedance probe tip within a fastener aperture of the insert, the impedance probe tip sized to project within the fastener aperture and to engage the insert around a circumference of the impedance probe tip such that the impedance probe tip is prevented from moving along a top surface of the structure when inserted within the fastener aperture, applying a low frequency vibration to the insert via the impedance probe tip, measuring the response frequency to the low frequency vibration at the impedance probe tip, determining whether the response frequency is within a pre-determined acceptable frequency range, and if the resonant response frequency is within the pre-determined acceptable frequency range, determining that the insert is properly installed within the insert aperture.
