This AD requires verifying that the affected components are installed on the airplane, revising the structural life limits in the existing structural deviation inspection requirements (SDIR) airplane document, and replacing affected components if necessary. The FAA is issuing this AD to address the unsafe condition on these products. DATES: This AD is effective March 30, 2021.
