Description

The FAA is adopting a new airworthiness directive (AD) for certain Textron Aviation Inc. 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. The AD requires revising the Airworthiness Limitations section of the existing aircraft maintenance manual or instructions for continued airworthiness and updating the approved maintenance or inspection program. The FAA is issuing this AD to address an unsafe condition that could result in reduced structural integrity and wing separation from the fuselage in flight.
