Duncan Aviation announced it is developing a Supplemental Type Certificate (STC) for Flight Data Recorders (FDRs) for numerous Hawker aircraft models. The STC will be the basis for an Approved Model List (AML) that will initially provide a certification path for Hawker owner/operators worldwide who need to install an FDR in order to operate in Mexican airspace or in airspace worldwide where FDRs are required, to meet the requirements of their Safety Management Systems (SMS) and/or to meet other industry standards.The new STC is for Collins Aerospace Proline 21-equipped Hawker models 750, 800Xp, 850XP, and 900XP. The STC also covers the installations of an AeroCorder 100 FDR from BendixKing and a Modular Acquisition Unit (MAU) and Quick Access Recorder (QAR) from Flight Data Systems.The AML STC will meet the mandate established in 2020 by the Mexican Agencia Federal Aviacion Civil (AFAC) regarding the performance and functionality of Flight Data Recorders on aircraft flying in Mexican airspace. After gaining approval from the FAA and the AFAC, Duncan Aviation will seek approval for its STC from the European Union Aviation Safety Agency (EASA) and Brazil's National Civil Aviation Agency (ANAC).Duncan Aviation Satellite Shop in Houston, Texas, is installing the equipment for a Hawker 900XP customer who routinely flies in Mexican Airspace."We want to be able to help those Hawker owner/operators worldwide whose aircraft are not equipped with FDRs or whose FDRs are obsolete," says Manager of the Houston Satellite Shop Mark Winter. "Although the mandate went into effect in 2020, we're just now seeing the rules of engagement, and our STC addresses all of the issues. The Hawker series aircraft will be the first model to be added to this AML STC."The AeroCorder 100 FDR includes an ARINC 717 interface for data collection in today's digital cockpits. To expand the AeroCorder 100's capabilities, a Data Acquisition Module (DAM) is available from Flight Data Systems. The MAU converts the AeroCorder 100 into a Data Acquisition and Crash Recorder System.Supporting a range of signal inputs, including digital, analog, and discrete, Flight Data Systems' MAU allows multiple aircraft sensor feeds to be harmonized into one, which will be received by the BendixKing AeroCorder 100. Customizable and expandable, Flight Data Systems' MAU can be installed in a variety of aircraft and can record additional parameters."Our customizable MAU offers a cost-effective means to fully conform to international regulations," said Flight Data Systems Business Development Executive Scott Hall. "We are excited to work alongside Duncan Aviation to implement this solution onboard the Hawker, and, in time, to as many aircraft that require this solution."
