Airworthiness Directives; McDonnell Douglas Model DC-9-80 Series Airplanes and Model MD-88 Airplanes

The Federal Aviation Administration (FAA) has issued an airworthiness directive (AD) for certain McDonnell Douglas Model DC-9-80 series and Model MD-88 airplanes, requiring a one-time visual inspection to check for self-aligning nuts at specific locations on the aft pressure bulkhead tee. The inspection aims to prevent failures of Hi-Lok pin fasteners and subsequent damage to the bulkhead tee, which could lead to fatigue cracking and reduced structural integrity.
