summary: 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.
