The Federal Aviation Administration (FAA) has issued a new airworthiness directive (AD) for certain MHI RJ Aviation ULC Model CL-600-2B19 airplanes, responding to issues with the structural life limits of some landing gear components. These limits were not properly updated during repairs, potentially leading to landing gear collapse and resulting in airplane damage and danger to passengers. The directive requires checking and revising these limits in airplane documents and replacing affected parts when necessary. This rule is to ensure the safe operation of the aircraft and is effective from March 30, 2021.
Simple Explanation
The FAA is making some airplane companies check and fix parts of the landing gear on certain planes because they might not last as long as they should, which could be dangerous. They need to look at the airplane's records and possibly change out some old parts to keep everyone safe.
