Federal Aviation Administration May 2018 – Federal Register Recent Federal Regulation Documents

We are adopting a new airworthiness directive (AD) for certain Airbus Model A330-301, -321, -322, -341, and -342 airplanes; Model A340-200 series airplanes; and Model A340-300 series airplanes. This AD requires contacting the FAA to obtain instructions for addressing the unsafe condition on these products, and doing the actions specified in those instructions. This AD was prompted by reports of cracks on both left-hand (LH) and right-hand (RH) sides on certain frame (FR) locations. We are issuing this AD to address the unsafe condition on these products.

We propose to supersede Airworthiness Directive (AD) 2015-17- 04, which applies to certain Bombardier, Inc., Model CL-600-2C10 (Regional Jet Series 700, 701, & 702), Model CL-600-2D15 (Regional Jet Series 705), and Model CL-600-2D24 (Regional Jet Series 900) airplanes. AD 2015-17-04 requires replacement of left and right fixed control rods and lever assemblies of the elevator control system. Since we issued AD 2015-17-04, we have received a report indicating that certain revisions of the service information were missing instructions. This proposed AD would require a detailed visual inspection of the key washers and self- locking nuts of the elevator control linkages and corrective actions if necessary. We are proposing this AD to address the unsafe condition on these products.

We are superseding Airworthiness Directive (AD) 2016-25-18, which applied to certain Bombardier, Inc., Model BD-700-1A10 and BD- 700-1A11 airplanes. AD 2016-25-18 required an inspection for discrepancies of the attachment points of the links between the engine rear mount assemblies, and corrective actions if necessary. This AD requires an inspection of certain attachment points, corrective action if necessary, and replacement of certain bolts and nuts in the engine rear mount assemblies. This AD also adds airplanes to the applicability. This AD was prompted by the determination that replacement of certain nuts and bolts in the engine rear mount assemblies is necessary. We are issuing this AD to address the unsafe condition on these products.

We are adopting a new airworthiness directive (AD) for Rolls- Royce plc (RR) Viper Mk. 601-22 turbojet engines. This AD requires removing the oil pump assembly, part number (P/N) V112027, and oil pressure filter, P/N V21264, from service and replacing them with parts eligible for installation. This AD was prompted by a report of an engine failure caused by installation of an incorrect oil filter. We are issuing this AD to correct the unsafe condition on these products.

This proposed AD was prompted by a report of deficient fatigue performance of high strength steel used in forgings. Components made from the affected high strength steel are installed on the main landing gear (MLG), nose landing gear (NLG), and center landing gear (CLG). This proposed AD would require identifying the part number and serial number of certain components installed on the MLG, NLG, and CLG; replacing affected parts; identifying the airplane's weight variant; and determining the applicable life limit for certain components installed on the MLG, NLG, and CLG. We are proposing this AD to address the unsafe condition on these products.

We propose to supersede Airworthiness Directive (AD) 98-16-03 for SOCATA Models TB 9 and TB 10 airplanes. This proposed AD results from mandatory continuing airworthiness information (MCAI) originated 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 fatigue cracking of the wing front attachments on the wing and fuselage sides. We are issuing this proposed AD to require actions to address the unsafe condition on these products.

We are adopting a new airworthiness directive (AD) for certain The Boeing Company Model 737-200, -300, -400, and -500 series airplanes. This AD was prompted by reports of cracks in the frame web common to the stringer ties adjacent to the air-conditioning support brackets. This AD requires an inspection of the frame for any air- conditioning bracket assembly or intercostal, and, depending on the results, repetitive inspections of the frame web for cracking of certain locations, and applicable on-condition actions. We are issuing this AD to address the unsafe condition on these products.

This action amends controlled airspace at Pocatello Regional Airport, Pocatello, ID, by amending Class D airspace and Class E airspace designated as a surface area; removing Class E airspace designated as an extension to a Class D or E surface area; and amending Class E airspace extending upward from 700 feet above the surface. Also, this action updates the airport's geographic coordinates for the associated Class D and E airspace areas to reflect the FAA's current aeronautical database. Additionally, reference to the Pocatello VHF Omnidirectional Range/Tactical Air Navigation (VORTAC) is removed from the Class E airspace extending upward from 700 feet above the surface description. This action enhances the safety and management of instrument flight rules (IFR) operations at the airport.

This action proposes to modify Class D airspace, Class E surface area airspace, Class E airspace designated as an extension, and Class E airspace extending upward from 700 and 1,200 feet above the surface at Grant County International Airport (formerly Grant County Airport), Moses Lake, WA. This action also proposes to remove the Notice to Airmen (NOTAM) part-time status of Class E airspace designated as an extension, and update the airport name and geographic coordinates for the airport in the associated Class D and E airspace areas to match the FAA's aeronautical database. These changes are necessary to accommodate airspace redesign for the safety and management of instrument flight rules (IFR) operations at the airport. Also, an editorial change would be made to the Class D and Class E airspace legal descriptions replacing ``Airport/Facility Directory'' with the term ``Chart Supplement''.

This action proposes to amend Class E airspace extending upward from 700 feet above the surface at Gustavus Airport, Gustavus, AK.
