Airworthiness Directives; British Aerospace Model HS 748 Airplanes

The FAA is adopting a new airworthiness directive (AD) for all British Aerospace Model HS 748 airplanes. This AD requires repetitive inspections for fatigue cracking, corrosion, and other related discrepancies of the rear pressure bulkhead and associated areas, and the fin attachment fittings, particularly the fin link beam; and related investigative and corrective actions. This AD results from a structural integrity audit of the airplane that showed the importance of inspecting for fatigue cracking and corrosion of these areas. We are issuing this AD to detect and correct cracking, corrosion, and other related discrepancies of the rear pressure bulkhead and associated areas, and the fin attachment fittings, particularly the fin link beam, which could result in damage to the airplane structure or injury to airplane occupants.
