MAP176 - GPS Antenna adaptations

Sometimes during installation of approved modifications (e.g. STCs) in new aircraft MSNs, adaptations are needed in order to install the components properly. This modification deals with such a case where a GPS antenna installation turned out to be incompatible with the subject aircraft tail-fin, as the aircraft already has a GPS antenna installed in the same area. Adaptations were required, a new custom antenna mounting plate was installed solving the collision issues
