The Federal Aviation Administration (FAA) is proposing a new airworthiness directive (AD) for certain Airbus Canada Limited Partnership Model BD-500-1A11 airplanes. This action was spurred by an incident involving hydraulic fluid leakage caused by possibly using an uncalibrated torque wrench. The proposed rule requires proper torquing and sealing of the hydraulic fittings as detailed in a Transport Canada AD. This is intended to prevent potential hydraulic system failures and ensure the continued safety of these aircraft models.
Simple Explanation
The government wants airplanes from a company called Airbus Canada to check and fix some important parts because the tools used to tighten them might not have been correct. This is to make sure that these airplanes can fly safely without any problems.
