Yes, the iLevil 3 AW is NORSEE Approved. NORSEE is a production approval that allows us to legally sell units for installation on certified aircraft. Installation approval is given by a mechanic under 14 CFR 1.1 / 14 CFR 43 Appendix A definition of a Minor Alteration. If the mechanic deems the installation of the NORSEE device as minor, then the device can be installed with a simple logbook entry. If the mechanic feels that the installation is considered major, then a field approval will be needed for installation.
