Abstract

The FAA is adopting a new airworthiness directive (AD) for certain Textron Aviation Inc. (Textron) Model B300 and B300C airplanes. This AD was prompted by the manufacturer's revision of the airworthiness limitations manual (ALM) to introduce revised inspection intervals to detect cracks in the wing spar or wing supporting structure. This AD requires revising the Airworthiness Limitations section (ALS) of the existing aircraft maintenance manual (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.
