A Southern District of Florida grand jury last month indicted David Alexander Barcena for falsely certifying that a variety of aircraft parts were airworthy and able to be installed on commercial aircraft, according to the U.S. Department of Transportation’s (DOT) inspector general.

Specifically, the indictment alleges that between December 2016 and May 2017 Barcena certified commercial aircraft parts such as anti-icing valves, a hydraulic reservoir assembly, and a landing gear actuator as ready for service. The indictment further alleges that he used falsified FAA airworthiness approval tags for the parts. Barcena obtained the tags from a defunct Part 145 facility where he was employed as a chief inspector, according to the DOT inspector general.

The FAA’s Flight Standards Division Office in Miramar, Florida, is assisting the DOT inspector general in the investigation.
