Removal of Class A Airspace Area Exclusion
This action removes a provision in part 71 that excludes from Class A airspace, that portion of U.S. domestic airspace that overlies the Santa Barbara and Farallon Islands and the airspace south of latitude 25[deg]04'00'' North (overlying and in the vicinity of the Florida Keys). The effect of this provision is that the airspace from 18,000 feet MSL up to and including Flight Level (FL) 600 (within the excluded areas) is classified as Class G (uncontrolled) airspace which limits the flexibility for air traffic control operations.
Airworthiness Directives; Honeywell International Inc. (Type Certificate Previously Held by AlliedSignal Inc., Garrett Turbine Engine Company) Turbofan Engines
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.
Airworthiness Directives; Weatherly Aircraft Company Airplanes
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.
Airworthiness Directives; The Boeing Company Airplanes
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.
Airworthiness Directives; The Boeing Company Airplanes
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.
Airworthiness Directives; BAE Systems (Operations) Limited Airplanes
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.
Airworthiness Directives; Sikorsky Aircraft Corporation (Sikorsky) Helicopters
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.
