Federal Aviation Administration May 11, 2018 – Federal Register Recent Federal Regulation Documents

The Federal Aviation Administration (FAA) is issuing this notice to advise the public that it has published a Final Environmental Assessment and Finding of No Significant/Record of Decision for the Cleveland/Detroit Metroplex project.

We propose to adopt a new airworthiness directive (AD) for certain Pacific Aerospace Limited Model 750XL airplanes. This proposed AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and address an unsafe condition on an aviation product. The MCAI describes the unsafe condition as insufficient clearance between the pitot tubes and the primary support at the flame arrester intersection. We are issuing this proposed AD to require actions to address the unsafe condition on these products.

This action proposes to amend Class E airspace designated as an extension and Class E airspace extending upward from 700 feet above the surface at Aspen-Pitkin County Airport/Sardy Field, Aspen, CO, by realigning the Class E extension and removing the part-time Notice to Airmen (NOTAM) language from the legal description, and reducing the Class E airspace area extending upward from 700 feet above the surface and removing Class E airspace extending upward from 1,200 feet above the surface. This action would also update the airport's geographic coordinates 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 within the National Airspace System. Also, an editorial change would be made to the Class D airspace and Class E extension airspace legal descriptions replacing Airport/Facility Directory with the term Chart Supplement.

This action establishes Class E airspace extending upward from 700 feet above the surface at Manley Hot Springs Airport, Manley Hot Springs, AK, to accommodate new area navigation (RNAV) procedures at the airport. This action ensures the safety and management of instrument flight rules (IFR) operations within the National Airspace System. Also, this action corrects a rounding error of one second in degrees of latitude for the geographic coordinates of the airport.

We propose to adopt a new airworthiness directive (AD) for Airbus Helicopters Model AS-365N2 and AS 365 N3 helicopters with a lower strobe light installed. This proposed AD would require installing a cable mount, inspecting the lower strobe light wiring harness, and re-routing the wiring harness. This proposed AD is prompted by reports of interference between the lower strobe light wiring harness and the helicopter structure. The actions of this proposed AD are intended to prevent an unsafe condition on these helicopters.

We propose to adopt a new airworthiness directive (AD) for all The Boeing Company Model 737-600, -700, -700C, -800, -900, and -900ER series airplanes. This proposed AD was prompted by reports of loose, worn, or missing attachment bolts for the main landing gear (MLG) center door assemblies. This proposed AD would require repetitive detailed inspections of the forward and aft MLG center door assembly attachments for loose, missing, damaged, or bottomed out attachment bolts; any wear to the retention clip assemblies as applicable; and applicable on-condition actions. This proposed AD would also provide an optional terminating action for the repetitive inspections. Since this is a rotable parts issue, the applicability of this AD has been expanded beyond the airplanes listed in the related service bulletin to include all airplanes on which the MLG center door assemblies may be installed. We are proposing this AD to address the unsafe condition on these products.

We are superseding Airworthiness Directive (AD) 2015-15-13, which applied to certain Airbus Model A319 series airplanes; Model A320-211, -212, -214, -231, -232, and -233 airplanes; and Model A321- 111, -112, -131, -211, -212, -213, -231, and -232 airplanes. AD 2015- 15-13 required a modification of the potable water service panel and waste water service panel, including doing applicable related investigative and corrective actions. This AD requires a modification of the waste water and potable water service panels with new compliance times. This AD also removes certain airplanes from the applicability and adds Model A320-216 airplanes to the applicability. This AD was prompted by an evaluation by the design approval holder (DAH) indicating that the potable water and waste water service panel areas are subject to widespread fatigue damage (WFD). We are issuing this AD to address the unsafe condition on these products.

We propose to adopt a new airworthiness directive (AD) for all Airbus Model A300 series airplanes. This proposed AD was prompted by a revision of an airworthiness limitation items (ALI) document. This proposed AD would require revising the maintenance or inspection program, as applicable, to incorporate the specified maintenance requirements and airworthiness limitations. We are proposing this AD to address the unsafe condition on these products.

We are adopting a new airworthiness directive (AD) for all The Boeing Company Model 787-8 airplanes. This AD requires inspecting the part number of the occupant restraint system on the standard attendant seats, and doing additional inspections and corrective actions if necessary. This AD was prompted by a report of loose attachment bolts on the occupant restraint system on a standard attendant seat due to the bolts being over-torqued during production. We are issuing this AD to address the unsafe condition on these products.
