Unpublished, time-sensitive and proposed rules for January 26, 2016:
TEMPORARY RULE: The Coast Guard has issued a temporary deviation from the operating schedule that governs the Chicago and Northwestern Railroad Drawbridge across the Mississippi River, mile 839.2, at St. Paul, Minnesota. The deviation is necessary to allow the bridge owner time to perform preventive maintenance that is essential to the continued safe operation of the drawbridge, and is scheduled in the winter when there is less impact on navigation. This deviation allows the bridge to be closed to navigation. This deviation is effective without actual notice from January 26, 2016 until 11:59 p.m., February 6, 2016. For the purposes of enforcement, actual notice will be used from 12:01 a.m., January 18, 2016 until 11:59 p.m., February 6, 2016.
RULE: We are adopting a new airworthiness directive (AD) for all Airbus Model A318–111 and –112 airplanes; Model A319–111, –112, and –115 airplanes; Model A320–214 airplanes; and Model A321–111, –112, –211, –212, and –213 airplanes. This AD was prompted by reports of cracked cadmium-plated lock nuts that attach the hinge to the fan cowl door. This AD requires inspecting to determine the serial number of each engine fan cowl door, inspecting for cracking of the hinge lock nuts of any affected door, and replacing the lock nuts if necessary. We are issuing this AD to detect and correct cracking of the hinge lock nuts, which could result in separation of the hinge from the fan cowl door, in-flight loss of the door, and consequent damage to the airplane. This AD becomes effective March 1, 2016.
RULE: We are adopting a new airworthiness directive (AD) for certain Airbus Model A319–113, A319–114, A320–211, and A320–212 airplanes. This AD was prompted by a report that the aft mount pylon bolts of the CFM56– 5 engines may have been installed using the wrong torque values. This AD requires identification of engines that were installed using the wrong torque values and re-torque of the four aft mount pylon bolts of those engines. We are issuing this AD to detect and correct improper torque of the aft mount pylon bolts, which, if combined with any maintenance damage, could lead to aft engine mount failure, possibly resulting in engine detachment and consequent reduced control of the airplane. This AD becomes effective March 1, 2016.
