Boeing Issues New Airworthiness Directive for MD-90-30 Airplanes to Address Fatigue Cracking Concerns

The Boeing Company is issuing a new Airworthiness Directive (AD) to address fatigue cracking of principal structural elements (PSEs) and safe-life limited parts on its Model MD-90-30 airplanes. The new directive requires revising the maintenance or inspection program to incorporate a new PSE requirement for the rear spar caps of the horizontal stabilizer.
