This action amends the time of designation for restricted area R-3002G at Fort Benning, GA, by removing the words ``local time'' and adding the words ``Eastern time'' to the published time of designation. The majority of the R-3002 complex (i.e., R-3002A through F) lies within the Eastern time zone. However, R-3002G is a small segment that is in the Central time zone. Since the Eastern time zone is predominant and is used for scheduling activities in the entire complex, the time of designation for R-3002G is amended to avoid confusion.

We propose to adopt a new airworthiness directive (AD) for all The Boeing Company Model 767 airplanes. This proposed AD was prompted by a report of a rotary actuator for the trailing edge (TE) flap that had slipped relative to its mating reaction ring, which is attached to the flap support rib. This proposed AD would require repetitive inspections for corrosion of the fixed ring gear and reaction ring splines of the rotary actuator assembly for each support position, and related investigative and corrective actions if necessary. We are proposing this AD to detect and correct reaction ring gears and rotary actuator gears from becoming disengaged with flaps extended and causing an uncommanded roll due to flap blowback, overload, or flap departure from the airplane, which could compromise safe flight and landing of the airplane.

We propose to supersede Airworthiness Directive (AD) 2005-14- 07, which applies to certain The Boeing Company Model 727, 727C, 727- 100, 727-100C, 727-200, and 727-200F series airplanes. AD 2005-14-07 currently requires repetitive inspections of the carriage attach fittings on the inboard and outboard foreflaps of each wing for cracking and other discrepancies, and corrective actions if necessary. Since we issued AD 2005-14-07, we received a report of broken inboard and outboard carriage attach fittings of the outboard foreflaps found during an inspection. This proposed AD would reduce certain repetitive inspection intervals for the inboard and outboard carriage attach fittings for the outboard foreflaps, require previously optional terminating actions which install improved outboard foreflap carriage attach fittings, and add new initial and repetitive inspections of those fittings and corrective actions if necessary. We are proposing this AD to detect and correct fatigue cracking of the attach fittings of the foreflap carriage of the wings, which could result in partial or complete loss of the foreflap and consequent loss of controllability of the airplane.
