The Federal Aviation Administration (FAA) has proposed a new airworthiness directive for certain Bombardier Model BD-100-1A10 airplanes. This comes after reports of a malfunction where the inboard multi-function spoiler (MFS) surfaces failed to deploy due to missing notches on the piston seal of the MFS power control units (PCUs). The proposal requires inspection and possible replacement of the affected MFS PCUs to ensure safety and prevent potential structural damage or injury. This proposed directive is open for public comments until April 12, 2021.
Simple Explanation
The FAA wants to make a new rule for some Bombardier airplanes to check and fix a part of the plane's wing that might not open right, to keep everyone safe. People can say what they think about this rule until April 12, 2021.
