## Abstract

The FAA is adopting a new airworthiness directive (AD) for certain The Boeing Company Model 767-300F series airplanes. This AD was prompted by a report of a supplier notice of escapement documenting that some titanium cargo track crown fittings had suspect material certifications. This AD requires an X-ray fluorescence (XRF) spectrometer inspection to identify the material composition of the cargo track crown fittings or replacement of all cargo track crown fittings with new cargo track crown fittings, and applicable on- condition actions. The FAA is issuing this AD to address the unsafe condition on these products.
