The Federal Aviation Administration (FAA) has proposed a new airworthiness directive (AD) targeting Bombardier, Inc., Model BD-700-1A10 and BD-700-1A11 airplanes. This proposal was prompted by issues with sand and corrosion affecting elevator torque tube bearings, which could potentially hinder airplane pitch control. The AD mandates regular inspections, functional tests, and possible replacements of these parts to avert risks to flight safety. Comments on this proposed directive are due by April 12, 2021.
Simple Explanation
The FAA wants to make sure some planes are safe, so they are telling people to check certain parts often because sand and rust might make them work poorly, like if a toy robot's arms got stuck. They are also asking people to say what they think about this plan by April 12, 2021.
