Federal Register Highlights – 2/7/14

February 7, 2014

Unpublished, time-sensitive and proposed rules for February 7, 2014:

TEMPORARY RULE: The Coast Guard has issued a temporary deviation from the operating schedule that governs the Hwy 160 drawbridge across Three Mile Slough, mile 0.1, at Rio Vista, CA. The deviation is necessary to allow California Department of Transportation to replace the steel deck of the bridge lift span. This deviation allows the bridge to remain in the closed-to-navigation position during the deviation period. This deviation is effective without actual notice from February 7, 2014 until 5 a.m. on April 5, 2014. For the purposes of enforcement, actual notice will be used from 8 p.m. on February 3, 2014, until February 7, 2014.

RULE: We are adopting a new airworthiness directive (AD) for all Bae Systems (Operations) Limited Model BAe 146 series airplanes and Model Avro 146–RJ series airplanes. This AD was prompted by reports of excess solder deposited during overhaul on the frangible plug of a fire extinguisher, which prevented the release of the extinguishant. This AD requires a one-time inspection of certain engine and auxiliary power unit (APU) fire extinguishers to determine if the fire extinguishers are affected by excessive solder and corrective actions if necessary. We are issuing this AD to prevent the failure of a fire extinguisher to discharge, which reduces the ability of the fire protection system to extinguish fires in the engine or APU fire zones, possibly resulting in damage to the airplane and injury to the passengers. This AD becomes effective March 14, 2014.

RULE: We are superseding Airworthiness Directive (AD) 2011–03–13 for certain Bombardier, Inc. Model CL–600–2C10 (Regional Jet Series 700, 701, & 702) airplanes, Model CL–600– 2D15 (Regional Jet Series 705) airplanes, and Model CL–600–2D24 (Regional Jet Series 900) airplanes. AD 2011–03–13 required repetitive inspections of the rudder travel limiter (RTL) return springs and primary actuator, and corrective actions if necessary. This new AD requires replacing certain RTL return springs, including doing related investigative and corrective actions, if necessary; which is terminating action for the repetitive inspections. This new AD also revises the applicability. This AD was prompted by reports of failure of the RTL return spring. We are issuing this AD to prevent failure of the RTL, which would permit an increase of rudder authority beyond normal structural limits and consequently affect the controllability of the airplane. This AD becomes effective March 14, 2014.

RULE: We are adopting a new airworthiness directive (AD) for Costruzioni Aeronautiche Tecnam srl Model P2006T airplanes. This AD results from mandatory continuing airworthiness information (MCAI) issued by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as cracks of the nose landing gear (NLG) lower link. We are issuing this AD to require actions to address the unsafe condition on these products. This AD is effective March 14, 2014.

RULE: We are adopting a new airworthiness directive (AD) for Eurocopter Model EC225LP and AS332L1 helicopters with emergency floatation gear. The AD requires, before the next overwater flight, inspecting the strap installation on the hinged rods of the emergency flotation gear on both rear cradles for correct installation. If a strap is installed under the hinged rod median plate rather than over it, reinstalling the strap is required. The AD is prompted by incorrect routing of the straps on the hinged rods of the emergency flotation gear rear cradles. The actions are intended to detect incorrect strap installation and prevent failure of the rods or straps upon deployment of the emergency flotation gear, incorrect float position, and subsequent capsizing of the helicopter. This AD becomes effective February 24, 2014.

RULE: We are superseding Airworthiness Directive (AD) 2003–19–11 for certain Learjet Inc. Model 60 airplanes. AD 2003–19–11 required determining if a certain fuel crossflow tube is installed; and follow-on/corrective actions, as applicable. This new AD requires retaining all actions in AD 2003–19–11, and it also requires determining if a certain fuel crossflow tube is installed, performing repetitive measurements of the fuel crossflow tube and surrounding valves and cables, and doing corrective actions if necessary. In addition, this new AD expands the applicability of AD 2003–19–11. This AD was prompted by a report that airplanes produced since 2003 might also be subject to the unsafe condition; and that the minimum allowable clearance is not established in the airplane maintenance information. We are issuing this AD to prevent chafing and consequent failure of the fuel crossflow tube due to inadequate clearance between the tube and the flight control cables, which could result in loss of fuel from one fuel tank during normal operating conditions or loss of fuel from both main fuel tanks during fuel cross-feeding operations. This AD is effective March 14, 2014

RULE: We are adopting a new airworthiness directive (AD) for certain the Boeing Company Model 737–100, –200, –200C, –300, –400, and –500 series airplanes. This AD was prompted by a report of cracks in stringer splices at body station STA 360 and STA 908, between stringer (S) S–10L and S–10R; cracks in butt straps between S–5L and S–3L, and S–3R and S–5R; vertical chem-mill fuselage skin cracks at certain butt joints; and an instance of cracking that occurred in all those three structural elements on one airplane. This AD requires repetitive inspections for any cracking of stringer splices and butt straps, and related corrective and investigative actions if necessary. We are issuing this AD to detect and correct cracking in the three structural elements, which could result in the airplane not being able to sustain limit load requirements and possibly result in uncontrolled decompression. This AD is effective March 14, 2014.

TEMPORARY RULE: NMFS is prohibiting directed fishing for Pacific cod by catcher vessels less than 60 feet (18.3 meters (m)) length overall (LOA) using hook-and-line or pot gear in the Bering Sea and Aleutian Islands management area (BSAI). This action is necessary to prevent exceeding the 2014 Pacific cod total allowable catch allocated to catcher vessels less than 60 feet (18.3 m) LOA using hook-and-line or pot gear in the BSAI. Effective 1200 hours, Alaska local time (A.l.t.), February 4, 2014, through 2400 hours, A.l.t., December 31, 2014.
