Bombardier Planes Must Upgrade Safety Plans by February

## Summary

If you own or work with Bombardier BD-100-1A10 airplanes, listen up! Starting February 20, 2026, you’ll need to update your maintenance plans with new, stricter safety rules to keep flying safe and sound. This change helps prevent problems before they happen, and while it might mean some extra work, it’s all about keeping everyone in the sky secure.

## Abstract

The FAA is adopting a new airworthiness directive (AD) for all Bombardier, Inc., Model BD-100-1A10 airplanes. This AD was prompted by a determination that new or more restrictive airworthiness limitations are necessary. This AD requires revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations. The FAA is issuing this AD to address the unsafe condition on these products.
