Airworthiness Directives; Airbus SAS Airplanes
The FAA is adopting a new airworthiness directive (AD) for all Airbus SAS Model A300 B4-600, B4-600R, and F4-600R series airplanes, and Model A300 C4-605R Variant F airplanes (collectively called Model A300-600 series airplanes); and Model A310 series airplanes. This AD was prompted by a determination that new tests are necessary to address potential air leaks in the reservoir air pressurization lines. This AD requires repetitive pressurization tests of the reservoir air pressurization lines for pipe rupture and leaks, and repair or replacement if necessary, as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.
Airworthiness Directives; The Boeing Company Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for certain The Boeing Company Model 747-8 and 747-8F series airplanes. This proposed AD was prompted by an evaluation by the design approval holder (DAH) indicating that the skin lap joints at certain stringers are subject to widespread fatigue damage (WFD). This proposed AD would require modifying the left and right side lap joints of the fuselage skin, repetitive post-modification inspections for cracking, and applicable on-condition actions. The FAA is proposing this AD to address the unsafe condition on these products.
Airworthiness Directives; The Boeing Company Airplanes
The FAA proposes to supersede Airworthiness Directive (AD) 2016-07-28, which applies to all The Boeing Company Model DC-9-81 (MD- 81), DC-9-82 (MD-82), DC-9-83 (MD-83), and DC-9-87 (MD-87) airplanes, and Model MD-88 airplanes. AD 2016-07-28 requires repetitive eddy current high frequency (ETHF) inspections for any cracking in the left and right side center wing lower skin, and repair if any crack is found. Since the FAA issued AD 2016-07-28, the FAA has determined it is necessary to expand the inspection area to include adjacent stringers with similar stress levels and to perform an inspection with increased sensitivity for crack detection. This proposed AD would retain certain requirements of AD 2016-07-28, expand the inspection area, and require new inspections. The FAA is proposing this AD to address the unsafe condition on these products.
Airworthiness Directives; Gulfstream Aerospace Corporation Airplanes
The FAA is adopting a new airworthiness directive (AD) for all Gulfstream Aerospace Corporation (Gulfstream) Models GVI, GVII-G500, and GVII-G600 airplanes. This AD requires revising the airplane flight manual (AFM) by attaching an airplane flight manual supplement (AFMS), which contains new or revised operating limitations, abnormal procedures, and emergency procedures. This AD was prompted by reports of continued flight after a flight control surface shutdown. If flight is continued after a flight control surface shutdown, the airplane is left without protection against flight control surface hard-over and force fight events on the remaining, operable flight control surfaces. The FAA is issuing this AD to address the unsafe condition on these products.
Airworthiness Directives; Airbus Helicopters
The FAA is adopting a new airworthiness directive (AD) for certain Airbus Helicopters Model AS350B, AS350BA, AS350B1, AS350B2, AS350B3, AS350C, AS350D, A350D1, AS355E, AS355F, AS355F1, AS355F2, AS355N, and AS355NP helicopters. This AD requires repetitive inspections of the installation of the pull cables on the emergency float kits. This AD was prompted by the results of an accident investigation and subsequent reports of difficulty pulling the emergency float kit float activation handle installed on the pilot cyclic. The FAA is issuing this AD to address the unsafe condition on these products.
Airworthiness Directives; Bombardier, Inc. Airplanes
The FAA is adopting a new airworthiness directive (AD) for all Bombardier, Inc., Model CL-600-2C10 (Regional Jet Series 700, 701 & 702) airplanes; Model CL-600-2D15 (Regional Jet Series 705) airplanes; Model CL-600-2D24 (Regional Jet Series 900) airplanes; and Model CL- 600-2E25 (Regional Jet Series 1000) airplanes. This AD was prompted by a report of incorrectly installed flight compartment door edge protection plates on both sides of the upper decompression panel. This AD requires revising the existing maintenance or inspection program, as applicable, to incorporate a functional check of the flight compartment door decompression latches. The FAA is issuing this AD to address the unsafe condition on these products.
Proposed Amendment of Class D Airspace; Jacksonville NAS, FL, and Proposed Amendment of Class D and Class E Airspace; Mayport, FL
This action proposes to amend Class D airspace for Jacksonville NAS, FL, by updating the name and geographical coordinates of Jacksonville NAS, (Towers Field, previously Jacksonville NAS), and Herlong Recreational Airport (previously Herlong Airport). This action would also amend Class D airspace and Class E airspace designated as an extension to Class D or E surface area by updating geographic coordinates of Mayport NAS, and the name and geographic coordinates of Jacksonville Executive Airport at Craig, (previously Craig Municipal Airport). Controlled airspace is necessary for the safety and management of instrument flight rules (IFR) operations in the area. This action also would make an editorial change replacing the term Airport/Facility Directory with the term Chart Supplement in the legal descriptions of associated Class D and E airspace.
