Federal Aviation Administration June 2017 – Federal Register Recent Federal Regulation Documents

This action proposes to amend Class E airspace at Wellsboro, PA, as the airspace surrounding Wellsboro Johnston Airport was inadvertently removed. Controlled airspace is necessary for the safety and management of instrument flight rules (IFR) operations at the airport.

This action proposes to establish Class E airspace extending upward from 700 feet above the surface at Highland Community Hospital Heliport, Picayune, MS, to accommodate new area navigation (RNAV) global positioning system (GPS) standard instrument approach procedures (SIAPs) serving Highland Community Hospital Heliport. Controlled airspace is necessary for the safety and management of instrument flight rules (IFR) operations at the heliport.

This action amends Class E airspace at Murray, KY, as the Calloway non-directional beacon (NDB) has been decommissioned, requiring airspace reconfiguration at Kyle-Oakley Field Airport. This action enhances the safety and airspace management of instrument flight rules (IFR) operations at the airport. This action also updates the geographic coordinates of the airport and updates the airspace designation header.

We are superseding Airworthiness Directive (AD) 98-13-14, for certain Airbus Model A320-211, -212, and -231 airplanes. AD 98-13-14 required repetitive inspections of certain fastener holes of the aft fuselage, and corrective action if necessary. This new AD continues to require the actions in AD 98-13-14, with revised inspection compliance times. This AD was prompted by identification of cracks in the fastener holes of the former junction of the aft fuselage, which occurred during a fatigue test; and a determination that certain compliance times specified in AD 98-13-14 must be reduced. We are issuing this AD to address the unsafe condition on these products.

We propose to adopt a new airworthiness directive (AD) for all Dassault Aviation Model MYSTERE-FALCON 900 airplanes. This proposed AD was prompted by a determination that new or more restrictive maintenance requirements and/or airworthiness limitations are necessary. This proposed AD would require revising the maintenance or inspection program, as applicable, to incorporate new or more restrictive maintenance requirements and/or airworthiness limitations. We are proposing this AD to address the unsafe condition on these products.

We propose to adopt a new airworthiness directive (AD) for certain Dassault Aviation Model FALCON 900EX airplanes. This proposed AD was prompted by a determination that new or more restrictive maintenance requirements and/or airworthiness limitations are necessary. This proposed AD would require revising the maintenance or inspection program, as applicable, to incorporate new or more restrictive maintenance requirements and/or airworthiness limitations. We are proposing this AD to address the unsafe condition on these products.

We propose to adopt a new airworthiness directive (AD) for various normal and transport category rotorcraft with certain Honeywell EGPWS installed. This proposed AD would require updating the software version of the EGPWS. This proposed AD is prompted by a software defect that prevents the EGPWS from providing terrain warnings. The proposed actions are intended to address an unsafe condition on these products.

Notice is being given that the FAA is considering a request from the Town of Nantucket in Nantucket, MA, to change the current land use from aeronautical use to non-aeronautical use of a 5 acre parcel of land. The parcel is located in the northwestern quadrant of the airport and is adjacent to other non-airport parcels used for industrial and/or commercial use properties. The parcel is currently identified as surplus for non-aeronautical use on the airport's September 16, 2015 Airport Layout Plan. The parcel will be used to generate non- aeronautical revenue through the lease of land for industrial/ commercial use. All revenues through the leasing of the parcel will continue to be subject to the FAA's revenue-use policy and dedicated to the maintenance and operation of Nantucket Memorial Airport.

We propose to adopt a new airworthiness directive (AD) for all The Boeing Company Model 737-100, -200, -200C, -300, -400, and -500 series airplanes. This proposed AD was prompted by reports of cracking in the upper aft skin at the rear spar of the wings. This proposed AD would require repetitive inspections for cracking of the upper aft skin of the wings, and repair if necessary. We are proposing this AD to address the unsafe condition on these products.

We propose to adopt a new airworthiness directive (AD) for Northrop Grumman LITEF GmbH LCR-100 Attitude and Heading Reference System (AHRS) units installed on various aircraft. This proposed AD would require removing certain LCR-100 AHRS units from service. This proposed AD is prompted by test results showing loss of or invalid data. The proposed actions are intended to prevent an unsafe condition on these products.

This special condition is for the Pilatus Aircraft Limited PC- 12, PC-12/45, and PC-12/47 airplanes. These airplanes, as modified by Innovative Solutions & Support, Inc., will have a novel or unusual design feature associated with the use of an autothrust system. The applicable airworthiness regulations do not contain adequate or appropriate safety standards for this design feature. This special condition contains the additional safety standards the Administrator considers necessary to establish a level of safety equivalent to that established by the existing airworthiness standards.

This action proposes to modify Class D airspace, Class E surface area airspace, Class E airspace extending upward from 700 feet above the surface, and Class E airspace extending upward from 1,200 feet above the surface at Cheyenne Regional/Jerry Olson Field Airport (formerly, Cheyenne Airport), Cheyenne, WY. Airspace redesign is necessary due to the decommissioning of the Cheyenne instrument landing system (ILS) locator outer marker and removal of the Cheyenne VHF Omnidirectional Range/Tactical Air Navigation (VORTAC) from the airspace description as the FAA transitions from ground-based navigation aids to satellite-based navigation. Also, this action would update the airport name and geographic coordinates for Class D and E airspace areas to reflect the FAA's current aeronautical database.

We propose to adopt a new airworthiness directive (AD) for 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. This proposed AD was prompted by reports of cracking of various structures in the bulkhead. This proposed AD would require an inspection for cracking in these structures, and corrective actions if necessary. We are proposing this AD to address the unsafe condition on these products.

We propose to adopt a new airworthiness directive (AD) for certain The Boeing Company Model 757-200, -200CB, and -300 series airplanes. This proposed AD was prompted by a report of fatigue cracking found in a certain fuselage frame web. This proposed AD would require inspecting the fuselage frame for existing repairs, repetitive inspections of the frame, and applicable repairs. We are proposing this AD to address the unsafe condition on these products.

We propose to adopt a new airworthiness directive (AD) for certain Bombardier, Inc., Model CL-600-2B16 (CL-601-3A, CL-601-3R, and CL-604 Variants) airplanes. This proposed AD was prompted by reports of fuel leaks in the engine and auxiliary power unit (APU) electrical fuel pump (EFP) cartridge/canister electrical connectors and conduits. This proposed AD would require repetitive inspections for fuel leakage at the engine and APU fuel pumps, and related investigative and corrective actions if necessary. We are proposing this AD to address the unsafe condition on these products.

We propose to supersede Airworthiness Directive (AD) 2015-15- 10, for all Airbus Model A318, A319, A320, and A321 series airplanes. AD 2015-15-10 currently requires repetitive inspections of the trimmable horizontal stabilizer actuator (THSA) for damage, and replacement if necessary; and replacement of the THSA after reaching a certain life limit. Since we issued AD 2015-15-10, an additional life limit for the THSA has been established, based on flight cycles. In addition, the THSA manufacturer has issued service information which, when accomplished, increases the life limit of the THSA. This proposed AD would require repetitive detailed inspections of certain THSAs, and related investigative and corrective actions if necessary. We are proposing this AD to address the unsafe condition on these products.
