## Summary

If you own a Textron Aviation Model 525B airplane, listen up! The FAA says you need to update your maintenance manual with stricter inspection rules to catch potential engine mount cracks early. This change kicks in on March 13, 2026, so get ready to keep your plane safe and sound without breaking the bank.

This AD requires revising the Airworthiness Limitations Section (ALS) of the existing AMM or instructions for continued airworthiness (ICA) and the existing approved maintenance or inspection program, as applicable. The FAA is issuing this AD to address the unsafe condition on these products.
