Action
Final rule.
Summary
We are adopting a new airworthiness directive (AD) for all Fokker Services B.V. Model F28 Mark 0070 and 0100 airplanes. This AD was prompted by a report of cracking in a certain section of the secondary structure of the wing. This AD requires a one-time inspection of the trailing edge rib, and corrective action if necessary. We are issuing this AD to address the unsafe condition on these products.
