Airworthiness Directives; Boeing Model 767-200, -300, and -300F Series Airplanes

The FAA is adopting a new airworthiness directive (AD) for certain Boeing Model 767-200, -300, and -300F series airplanes. This AD requires repetitive high frequency eddy current inspections and detailed inspections of the left and right butt line (BL) 25 vertical chords for cracks, and corrective actions if necessary. This AD is prompted by findings of cracks in the fillet radii of the left and right BL 25 vertical chords common to the nose wheel well bulkhead at station 287. We are issuing this AD to detect and correct cracks in the left and right BL 25 vertical chords, which could grow downward into a critical area that serves as a primary load path for the nose landing gear (NLG) and result in the collapse of the NLG during landing.
