Federal Register Highlights – 3/31/16

April 3, 2016

Unpublished, time-sensitive and proposed rules for March 31, 2016:

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 cracking of the main fitting of the nose landing gear (NLG) and a determination that a new safe-life limitation for affected NLG main fittings has not been mandated. This AD requires replacing affected NLG main fittings that have exceeded the safe-life limitation with a new or serviceable fitting. We are issuing this AD to prevent collapse of the NLG, which if not corrected, could lead to degradation of direction control on the ground or an un-commanded turn to the left, and a consequent loss of control of the airplane on the ground, possibly resulting in damage to the airplane and injury to occupants. This AD becomes effective May 5, 2016.

RULE: We are adopting a new airworthiness directive (AD) for certain Honeywell International Inc. (Honeywell) TFE731–4, –4R, –5AR, –5BR, and –5R turbofan engines. This AD was prompted by a report of certain interstage turbine transition (ITT) ducts failing to meet containment capability requirements. This AD requires replacing certain ITT ducts. We are issuing this AD to prevent failure of the ITT duct, which could lead to an uncontained part release, damage to the engine, and damage to the airplane. This AD is effective May 5, 2016.

RULE: We are superseding Airworthiness Directive (AD) 2014–07– 04R1 for certain Model S–92A helicopters. AD 2014–07–04R1 required repetitive inspections in the upper deck area for incorrectly installed clamps and chafing between the electrical wires and the hydraulic lines and replacing any unairworthy wires or hydraulic lines. This new AD requires altering the wiring system in the upper deck area to correct the unsafe condition described in AD 2014–07–04R1. We are issuing this AD to prevent a fire in an area of the helicopter without extinguishing capability and subsequent loss of control of the helicopter. This AD is effective May 5, 2016.

RULE: We are adopting a new airworthiness directive (AD) for certain The Boeing Company Model 747–100, 747–100B, 747–100B SUD, 747–200B, 747–300, 747SR, and 747SP series airplanes. This AD was prompted by an evaluation by the design approval holder (DAH) indicating that the upper chords of the upper deck floor beams are subject to widespread fatigue damage (WFD). This AD requires repetitive inspections for cracks at the floor panel attachment fastener holes; repetitive inspections for cracks in the upper and lower chords of the upper deck floor beams at permanent fastener locations; repetitive inspections for cracks in certain repaired and modified areas; and related investigative and corrective actions if necessary. This AD also requires repetitive replacement of the upper chords of the upper deck floor beams, including pre-replacement inspections and corrective action if necessary; and post-replacement repetitive inspections and repair if necessary. We are issuing this AD to detect and correct fatigue cracking of the upper chords of the upper deck floor beams. Undetected cracking could result in large deflection or deformation of the upper deck floor beams, resulting in damage to wire bundles and control cables for the flight control system, and reduced controllability of the airplane. Multiple adjacent severed floor beams could result in rapid decompression of the airplane. This AD is effective May 5, 2016.

RULE: We are adopting a new airworthiness directive (AD) for certain The Boeing Company Model 747–8 series airplanes. This AD requires an inspection to determine if all oxygen components in the passenger oxygen system are installed, installation of new O-rings, and corrective actions if necessary. This AD was prompted by a report that oxygen tube couplings in the passenger oxygen system could be missing or incorrectly installed. We are issuing this AD to detect and correct oxygen leaks from oxygen tube couplings in the passenger oxygen system, which could result in depletion of emergency oxygen at a faster rate than expected, reduce the passengers’ and crews’ protection from hypoxia at elevated cabin altitudes, and increase the risk of a fire. This AD is effective April 15, 2016.

RULE: We are adopting a new airworthiness directive (AD) for all Weatherly Aircraft Company Models 201, 201A, 201B, 201C, 620, 620A, 620B, 620B–TG, and 620TP airplanes. This AD requires visually inspecting the center and outer wing front spar lower hinge fittings for cracks and corrosion and taking all necessary corrective actions. This AD also requires sending the inspection results to the FAA. This AD was prompted by a report of cracks found on the center wing front spar lower hinge fitting. We are issuing this AD to correct the unsafe condition on these products. This AD is effective April 15, 2016.

TEMPORARY RULE: NMFS announces that the length of the recreational season for black sea bass in the exclusive economic zone (EEZ) of the South Atlantic will extend throughout the 2016–2017 fishing year. Announcing the length of recreational season for black sea bass is one of the accountability measures (AMs) for the recreational sector. This announcement allows recreational fishermen to maximize their opportunity to harvest the recreational annual catch limit (ACL) for black sea bass during the fishing season while managing harvest to protect the black sea bass resource. This rule is effective from 12:01 a.m., local time, April 1, 2016, until 12:01 a.m., local time, April 1, 2017, unless changed by subsequent notification in the Federal Register.

TEMPORARY RULE: NMFS is adjusting the commercial aggregated large coastal shark (LCS) and hammerhead shark management group retention limit for directed shark limited access permit holders in the Atlantic region from 36 LCS other than sandbar sharks per vessel per trip to 3 LCS other than sandbar sharks per vessel per trip. This action is based on consideration of the regulatory determination criteria regarding inseason adjustments. The retention limit will remain at 3 LCS other than sandbar sharks per vessel per trip in the Atlantic region through the rest of the 2016 fishing season or until NMFS announces via a notice in the Federal Register another adjustment to the retention limit or a fishery closure is warranted. This retention limit adjustment will affect anyone with a directed shark limited access permit fishing for LCS in the Atlantic region. This retention limit adjustment is effective at 11:30 p.m. local time April 2, 2016, through the end of the 2016 fishing season on December 31, 2016, or until NMFS announces via a notice in the Federal Register another adjustment to the retention limit or a fishery closure, if warranted.
