Summary
We propose to adopt a new airworthiness directive (AD) for certain The Boeing Company Model 767 airplanes. This proposed AD was prompted by a report of cracking of the vertical stiffener in the nose wheel well. This proposed AD would require repetitive inspections of the nose wheel well bulkhead stiffener for any cracking, and corrective actions if necessary. We are proposing this AD to address the unsafe condition on these products.
