EAA and AOPA have filed formal comments with the FAA that raise questions about the agency’s proposed Airworthiness Directive regarding certain NavWorx ADS-B units. AOPA asked the FAA to provide more information about the unit’s reported deficiencies, and to better explain the necessity for the proposed AD. “The safety benefits offered by UAT [Universal Access Transceiver] technology, along with the cost of compliance, is leading to confusion and concern,” said Justin Barkowski, AOPA director of regulatory affairs.
