## Abstract

The FAA is adopting a new airworthiness directive (AD) for all Dassault Aviation Model FALCON 7X airplanes. This AD was prompted by a determination that certain left-hand (LH) and right-hand (RH) pylon bleed air leak detectors (BALDs) might be defective, due to incorrect manufacturing processes and incomplete acceptance test procedures. This AD requires a one-time operational check of affected parts and, depending on findings, accomplishment of applicable corrective action, and limits the installation of affected parts under certain conditions, as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.
