This operator had major long standing radio issues. These conditions and snags were contributing to a very unsafe environment for the pilot and ground crews. At one point they had to rely on a 1 click for yes and 2 clicks for no to communicate. The project was taken on while the helicopter was having a head changed and was to be accomplished in a very short time period.
The Bendix/King Audio Panel and intercom were removed and an AEM AMS 42 Audio Panel was installed. All of the avionics systems were completely rewired which included a Technisonic TFM 138B, Technisonic TFM 403 and Bendix/King KY196A VHF Comm.
The removal of all the old avionics wiring and complete avionics rewire and new audio panel were installed in a couple days. Meeting the operators contract obligations and will now provide reliable communications for many more years.
