Federal Aviation Administration November 5, 2015 – Federal Register Recent Federal Regulation Documents

The FAA assigned the Aviation Rulemaking Advisory Committee (ARAC) a new task to provide recommendations regarding occupant protection rulemaking in normal and transport category rotorcraft for older certification basis type designs that are still in production. The FAA amended regulations to incorporate occupant protection rules, including those for emergency landing conditions and fuel system crash resistance, for new type designs in the 1980s and 1990s. These rule changes do not apply to newly manufactured rotorcraft with older type designs or to derivative type designs that keep the certification basis of the original type design. This approach has resulted in a very low incorporation rate of occupant protection features into the rotorcraft fleet, and fatal accidents remain unacceptably high. At the end of 2014, only 16% of U.S. fleet had complied with the crash resistant fuel system requirements effective 20 years earlier, and only 10% had complied with the emergency landing requirements effective 25 years earlier. A recent fatal accident study has shown these measures would have been effective in saving lives. This notice informs the public of the new ARAC activity and solicits membership for the new Rotorcraft Occupant Protection Working Group.

This action corrects an error in a final rule published in the Federal Register of October 19, 2015, by amending the magnetic bearing to a true bearing in the Class E surface area airspace description for Farmington Regional Airport, Farmington, MO.

We are adopting a new airworthiness directive (AD) for certain The Boeing Company Model 787-8 airplanes. This AD was prompted by reports of missing plugs found prior to airplane delivery, during manufacturing inspections, at various locations in certain stringers of the lower lobe cargo compartments. This AD requires drilling a hole and installing and bonding plugs in certain stringers of the lower lobe cargo compartments. We are issuing this AD to detect and correct missing or misaligned plugs which, in the event of a fire, could cause an increased rate of loss of Halon in the lower cargo compartments, and result in the inability to extinguish a fire and consequent loss of control of the airplane.

We are adopting a new airworthiness directive (AD) for certain Lockheed Martin Corporation/Lockheed Martin Aeronautics Company Model 188 series airplanes. This AD was prompted by an evaluation by the design approval holder (DAH) indicating that the circumferential fuselage splice at fuselage-station (FS) 695 is subject to widespread fatigue damage (WFD). This AD requires an inspection for corrosion and previous repairs, severed stringers, cracking, and loose or distressed fasteners of the forward and aft ends of the stringer splices of certain stringers, inspection for cracking and modification of certain fastener holes common to the stringer and splice member at the forward and aft ends of the splice, and related investigative and corrective actions if necessary. We are issuing this AD to prevent loss of residual strength of the circumferential fuselage splice at FS 695, which could lead to rapid decompression of the cabin and potential loss of the airplane.
