Federal Register Highlights – 8/21/14

August 21, 2014

Unpublished, time-sensitive and proposed rules for August 21, 2014:

RULE: We are superseding Airworthiness Directives (AD) 2006–21–08, AD 2007–14–01, AD 2008–25–02, AD 2010–04–09, AD 2011–01–02, and AD 2012–16–05, for certain Airbus Model A330 and A340 series airplanes. AD 2006–21–08, AD 2007–14–01, AD 2008–25–02, AD 2010–04–09, AD 2011–01–02, and AD 2012–16–05 required revising the maintenance program or inspection program to incorporate certain maintenance requirements and airworthiness limitations for fuel tank systems. This new AD requires a new maintenance or inspection program revision. This AD was prompted by a determination that more restrictive maintenance requirements and airworthiness limitations are necessary. We are issuing this AD to prevent the potential of ignition sources inside fuel tanks, which, in combination with flammable fuel vapors, could result in fuel tank explosions and consequent loss of the airplane. This AD becomes effective September 25, 2014.

RULE: We are adopting a new airworthiness directive (AD) for all Airbus Model A300 series airplanes. This AD was prompted by an analysis of the impacts of extended service goal activities on Airbus Model A300 series airplanes. This AD requires revising the maintenance or inspection program. We are issuing this AD to prevent failure of flight critical systems. This AD becomes effective September 25, 2014.

RULE: We are adopting a new airworthiness directive (AD) for all Airbus Model A330–200 Freighter, A330–200, A330–300, and A340–200, A340–300, A340–500, and A340–600 series airplanes. This AD was prompted by a determination that the service life limits of the cabin pressure control system (CPCS) safety valves installed on the aft pressure bulkhead were being exceeded. This AD requires repetitive replacement of the CPCS safety valves with serviceable valves. We are issuing this AD to prevent exceeding the service life limits of the CPCS safety valves, which, in the event of a failure, could result in excessive positive or negative differential pressure in the fuselage and consequent incapacitation or injuries to airplane occupants. This AD becomes effective September 25, 2014.

RULE: We are superseding Airworthiness Directive (AD) 2012–10–53 for Eurocopter Deutschland GmbH (ECD) (now Airbus Helicopters) Model EC135P1, EC135P2, EC135P2+, EC135T1, EC135T2, and EC135T2+ helicopters. AD 2012–10–53 required, before further flight and at specified intervals, checking and inspecting the upper and lower main rotor hub (MRH) shaft flanges for a crack, and inspecting the lower hub-shaft flange bolt attachment areas for a crack. Since we issued AD 2012–10–53, it has been determined that it is safe to increase the visual inspection intervals of the MRH shaft flanges from 10 hours time-in-service (TIS) to 50 hours TIS and remove the inspection of the lower MRH shaft flange bolt attachment areas. This new AD continues to require checking and inspecting the upper and lower MRH shaft flanges for a crack. These actions are intended to detect a crack on the MRH shaft flange, which if not corrected, could result in failure of the MRH and subsequent loss of control of the helicopter. This AD is effective September 25, 2014.

RULE: We are superseding Airworthiness Directive (AD) 2005–15–04 for certain Bombardier, Inc. Model CL–600–1A11 (CL–600), CL–600–2A12 (CL–601), and CL–600–2B16 (CL–601– 3A, CL–601–3R, and CL–604 Variants) airplanes. AD 2005–15–04 required operators to assign serial numbers or part numbers to certain landing gear parts; establish the number of landings on the parts, if necessary; and revise the Airworthiness Limitations Section (ALS) of the Instructions for Continued Airworthiness (ICA) to reflect the new life limits of the landing gear parts. This new AD adds airplanes to the applicability, requires operators to assign serial numbers or part numbers to certain additional landing gear parts to establish the number of landings on the parts if necessary, and requires operators to record in all required airplane technical records and manuals the new part numbers, serial numbers, and landings assigned to these parts. This AD was prompted by reports that landing gear parts that have safe-life limits but do not have serial numbers or part numbers can be removed from one landing gear and re-installed on another, making tracking difficult. We are issuing this AD to prevent life-limited landing gear parts from being used beyond their safe-life limits, which could lead to collapse of the landing gear. This AD becomes effective September 25, 2014.

RULE: We are adopting a new airworthiness directive (AD) for certain Embraer S.A. Model EMB–500 airplanes. This AD was sent previously to all known U.S. owners and operators of these airplanes as an emergency AD. This AD requires an inspection and replacement as necessary of the barrel nuts at the horizontal stabilizer to vertical stabilizer attachment joint. This AD was prompted by mandatory continuing airworthiness information (MCAI) issued by the aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as cracking of the barrel nuts at the horizontal stabilizer to vertical stabilizer attachment joint. We are issuing this AD to correct the unsafe condition on these products. This AD is effective August 21, 2014 to all persons except those persons to whom it was made immediately effective by Emergency AD 2014–15–51, issued on July 25, 2014, which contained the requirements of this amendment.

TEMPORARY RULE: NMFS is reallocating the projected unused amount of Pacific cod from vessels using jig gear, catcher vessels greater than or equal to 60 feet (18.3 meters) length overall (LOA) using hook-and-line gear, and catcher vessels using trawl gear to catcher vessels less than 60 feet (18.3 meters) LOA using hook-and-line or pot gear in the Bering Sea and Aleutian Islands management area. This action is necessary to allow the 2014 total allowable catch of Pacific cod to be harvested. Effective August 19, 2014, through 2400 hours, Alaska local time (A.l.t.), December 31, 2014.

TEMPORARY RULE: This action closes the Georges Bank cod Trimester Total Allowable Catch Area for the remainder of Trimester 1, through August 31, 2014. Based on our projection, the common pool fishery has caught over 90 percent of its Georges Bank cod Trimester 1 total allowable catch triggering the regulatory requirement to close the area for the remainder of the trimester. This action is intended to prevent an overage of the common pool’s annual quota of Georges Bank cod. This action is effective August 18, 2014, through August 31, 2014.
