2012-2976 Airworthiness Directives; The Boeing Company Airplanes Proposed Rule We propose to supersede an existing airworthiness directive (AD) that applies to certain The Boeing Company Model 767 airplanes. The existing AD currently requires an inspection to detect cracks and fractures of the outboard hinge fitting assemblies on the trailing edge of the inboard main flap, and follow-on and corrective actions if necessary. For certain airplanes, the existing AD also requires a one- time inspection to determine if a tool runout option has been performed in the area. Since we issued that AD, we have received reports of hinge assembly fractures found before the currently-required inspection cycle compliance times on certain airplanes. This proposed AD reduces compliance times for Model 767-400ER series airplanes. In addition, this proposed AD would revise the applicability to include an additional airplane. We are proposing this AD to prevent the inboard aft flap from separating from the wing and potentially striking the airplane, which could result in damage to the surrounding structure and potential personal injury. 2012-02-09 2012 2 https://www.federalregister.gov/documents/2012/02/09/2012-2976/airworthiness-directives-the-boeing-company-airplanes https://www.govinfo.gov/content/pkg/FR-2012-02-09/pdf/2012-2976.pdf Transportation Department; Federal Aviation Administration 492,159 We propose to supersede an existing airworthiness directive (AD) that applies to certain The Boeing Company Model 767 airplanes.
