Action
Final rule.
Summary
The FAA is adopting a new airworthiness directive (AD) for all Textron Aviation, Inc., Model 525B airplanes. This AD was prompted by the manufacturer's revision of the aircraft maintenance manual (AMM) to introduce more restrictive inspection intervals. 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.
