Federal Aviation Administration March 29, 2016 – Federal Register Recent Federal Regulation Documents

This action removes restricted area R-4403 Gainesville, MS, and replaces it with an expanded area redesignated as R-4403A, B, C, E and F, Stennis Space Center (SSC), MS (the designation R-4403D is not used). The expanded restricted airspace is necessary to support essential National Aeronautics and Space Administration (NASA) testing and Naval Special Warfare Command (NSWC) training requirements.

We propose to adopt a new airworthiness directive (AD) for all Fokker Services B.V. Model F.28 Mark 0070 and Mark 0100 airplanes. This proposed AD was prompted by reports of cracking in a certain area of the pressure bulkhead webplate and skin connection angle. This proposed AD would require a one-time inspection of the affected pressure bulkhead webplate and skin connection angle, and corrective actions if necessary. We are proposing this AD to detect and correct cracking of the pressure bulkhead webplate and skin connection angle that could lead to sudden inflight decompression of the airplane resulting in injury to occupants.

We propose to supersede airworthiness directive (AD) 2015-12- 04, which applies to all Honeywell International Inc. (Honeywell) TPE331-1, -2, -2UA, -3U, -3UW, -5, -5A, -5AB, -5B, -6, -6A, -10, -10AV, -10GP, -10GT, -10P, -10R, -10T, -10U, -10UA, -10UF, -10UG, -10UGR, - 10UR, -11U, -12JR, -12UA, -12UAR, and -12UHR turboprop engines with certain Woodward fuel control unit (FCU) assemblies, installed. AD 2015-12-04 currently requires initial and repetitive dimensional inspections of the affected fuel control drives and insertion of certain airplane operating procedures into the applicable flight manuals. This proposed AD would correct compliance requirements and relax the inspection interval. We are proposing this AD to prevent failure of the fuel control drive, damage to the engine, and damage to the airplane.

This action modifies Class E airspace extending upward from 700 feet above the surface at Deer Lodge- City-County Airport, Deer Lodge, MT. After a review, the FAA found it necessary to amend the airspace area for the safety and management of standard instrument approach procedures for Instrument Flight Rules (IFR) operations at the airport.

This action changes the effective date of a final rule published in the Federal Register of February 8, 2016, amending Class E surface area airspace and Class E airspace designated as an extension at Rochester International Airport, Rochester, MN; and St. Cloud Regional Airport, St. Cloud, MN. This correction adds the part-time Notice to Airmen (NOTAM) language inadvertently removed from the Class E surface area descriptions for the above airports. Additionally, adjustment is made to the geographic coordinates of Rochester International Airport in the Class D airspace and Class E airspace extending upward from 700 feet above the surface. The Title is also amended to include Class D airspace.

We are adopting a new airworthiness directive (AD) for certain Airbus Model A319, A320, and A321 series airplanes. This AD was prompted by investigations that revealed that the cover seal of the brake dual distribution valve (BDDV) was damaged and did not ensure efficient sealing. This AD requires modifying the BDDVs having certain part numbers; modifying the drain hose of the BDDV; checking for the presence of water, ice, and hydraulic fluid; re-identifying the BDDV; and doing related investigative and corrective actions if necessary. We are issuing this AD to prevent damage to the BDDV, which could lead to water ingestion in the BDDV and freezing of the BDDV in flight, possibly resulting in loss of braking system function after landing.

We are adopting a new airworthiness directive (AD) for certain The Boeing Company Model 787-8 airplanes. This AD was prompted by a report of fuel leaking onto the hot exhaust portion of an engine as a result of an unintended leak path from the leading edge through the pylon. This AD requires installing new seal dams in the inboard and outboard corners of the aft pylon frame on the left and right engines, including an inspection for damage of the outboard blade seal and applicable corrective actions. We are issuing this AD to prevent fuel leaking from an unintended drain path from the leading edge through either the left or right pylon and onto the hot engine parts or brakes, which could lead to a major ground fire.
