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

We propose to adopt a new airworthiness directive (AD) for Rolls-Royce Deutschland Ltd & Co KG (RRD) Tay 620-15 turbofan engines. This AD limits service life of the low-pressure compressor (LPC) fan blades based on the number of dry-film lubricant (DFL) treatments. The AD was prompted by reports of LPC fan blade retention lug failures. We are proposing this AD to correct 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 more restrictive maintenance requirements and airworthiness limitations are necessary. This proposed AD would require revising the maintenance or inspection program, as applicable, to incorporate new and more restrictive maintenance requirements and airworthiness limitations. We are proposing this AD to address the unsafe condition on these products.

This action proposes to remove Class E airspace extending upward from 700 feet above the surface at Clarendon Municipal Airport, Clarendon, TX. The FAA is proposing this action due to the cancellation of the instrument procedures at the airport making this airspace no longer necessary.

We propose to adopt a new airworthiness directive (AD) for certain Dassault Aviation Model FALCON 2000EX airplanes. This proposed AD was prompted by the manufacturer revising the airplane maintenance manual (AMM) maintenance requirements and airworthiness limitations. This proposed AD would require revising the maintenance or inspection program, as applicable, to incorporate new maintenance requirements and airworthiness limitations. We are proposing this AD to address the unsafe condition on these products.

We are superseding Airworthiness Directive (AD) 2009-11-08, which applied to certain Airbus Model A330-202, -223, -243, -301, -322, and -342 airplanes. AD 2009-11-08 required repetitive special detailed (high frequency eddy current) inspections to detect cracking of the keel beam fitting horizontal flange edge at a certain frame (FR) on the left- and right-hand sides of the fuselage, and repair if necessary. This AD was prompted by a new fatigue and damage tolerance evaluation that concluded the current inspection thresholds and intervals had to be modified. 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. We are issuing this AD to address the unsafe condition on these products.

We are adopting a new airworthiness directive (AD) for all The Boeing Company Model 737-100, -200, -200C, -300, -400, and -500 series airplanes. This AD was prompted by reports of cracks found in the main landing gear (MLG) beam forward support fitting. This AD requires repetitive inspections for cracking of the MLG beam forward support fitting, and applicable on-condition actions. We are issuing this AD to address the unsafe condition on these products.

In accordance with the Paperwork Reduction Act of 1995, the FAA invites public comments about our intention to request the Office of Management and Budget (OMB) approval for a new information collection. The Federal Register Notice with a 60-day comment period soliciting comments on the following collection of information was published on November 2, 2017. The voluntary collection is part of the FAA's goal to more effectively and efficiently address noise complaints or inquiries it receives. The collection includes information such as name, email address, street or cross street, city, state, zip code, and a description of the aircraft noise complaint or inquiry. The level of information to be collected is necessary to allow the FAA to respond to the noise complaint or inquiry.

We propose to adopt a new airworthiness directive (AD) for all Airbus Model A300 series airplanes, 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 proposed AD was prompted by a report of yellow hydraulic system failure, including both braking accumulators, due to failure of the parking brake operated valve (PBOV). This proposed AD would require replacement of a certain PBOV with a different PBOV. We are proposing this AD to address the unsafe condition on these products.

We propose to adopt a new airworthiness directive (AD) for certain Airbus Model A318, A319, and A320 series airplanes; and Model A321-111, -112, -131, -211, -212, -213, -231, -232, -251N, -253N, and - 271N airplanes. This proposed AD was prompted by a revision of an airworthiness limitations document that specifies more restrictive maintenance requirements and airworthiness limitations. This proposed AD would require revising the maintenance or inspection program, as applicable, to incorporate revised fuel airworthiness limitations. We are proposing this AD to address the unsafe condition on these products.

The Federal Aviation Administration is seeking approval from the Office of Management and Budget (OMB) for a renewal of the existing Information Collection 2120-0768. As required by the Paperwork Reduction Act of 1995 (PRA), the purpose of this notice is to allow 30 days for public comment. The Information Collection was previously published in the Federal Register on February 12, 2018 and allowed 60 days for the public comment. The FAA proposes collecting information related to requests to operate Unmanned Aircraft Systems (UAS) in controlled airspace. The FAA will use the collected information to make determinations whether to authorize or deny the requested operation of UAS in controlled airspace. The proposed information collection is necessary to issue such authorizations or denials consistent with the FAA's mandate to ensure safe and efficient use of national airspace. In addition, the FAA proposes collecting information related to requests for waiver from the waivable provisions of the applicable regulations. The proposed information collection is necessary to determine whether the proposed operation is eligible for waiver consistent with the FAA's mandate to ensure safe and efficient use of national airspace. Several comments received were either positive or pertained to matters not directly addressed in this Information Collection.

This rule amends, suspends, or removes Standard Instrument Approach Procedures (SIAPs) and associated Takeoff Minimums and Obstacle Departure Procedures for operations at certain airports. These regulatory actions are needed because of the adoption of new or revised criteria, or because of changes occurring in the National Airspace System, such as the commissioning of new navigational facilities, adding new obstacles, or changing air traffic requirements. These changes are designed to provide for the safe and efficient use of the navigable airspace and to promote safe flight operations under instrument flight rules at the affected airports.

This action removes Class E airspace at Seven Springs, PA, as Seven Springs Borough Airport has been abandoned, and controlled airspace is no longer required. This action also removes reference to the Seven Springs, PA, Class E airspace area from the Somerset County Airport, Somerset, PA, description, and updates the geographic coordinates of Somerset County Airport to coincide with the FAA's aeronautical database. This action enhances the safety and management of controlled airspace within the national airspace system.

We are superseding Airworthiness Directive (AD) 2017-08-09 for DG Flugzeugbau GmbH Model DG-500MB gliders that are equipped with a Solo 2625 02 engine modified with a fuel injection system following the instructions of Solo Kleinmotoren GmbH Technische Mitteilung Nr. 4600-3 and identified as Solo 2625 02i. This 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 the potential of an in-flight shut-down and engine fire due to failure of the connecting stud for the two fuel injector mounts of the engine redundancy system on gliders equipped with a Solo 2625 02i engine. We are issuing this AD to add a model to the applicability and require actions to address the unsafe condition on these products.

These special conditions are issued for the BHTI Model 525 helicopter. This helicopter will have a novel or unusual design feature associated with fly-by-wire flight control system (FBW FCS) functions that affect the pilot awareness of the flight control modes while operating the helicopter. The applicable airworthiness regulations do not contain adequate or appropriate safety standards for this design feature. These special conditions contain the additional safety standards that the Administrator considers necessary to establish a level of safety equivalent to that established by the existing airworthiness standards.

We are adopting a new airworthiness directive (AD) for The Boeing Company Model 787-8 and 787-9 airplanes powered by Rolls-Royce plc (RR) Trent 1000-A2, Trent 1000-AE2, Trent 1000-C2, Trent 1000-CE2, Trent 1000-D2, Trent 1000-E2, Trent 1000-G2, Trent 1000-H2, Trent 1000- J2, Trent 1000-K2, and Trent 1000-L2 turbofan engines. This AD requires revising the airplane flight manual to limit extended operations (ETOPS). This AD was prompted by a report from the engine manufacturer indicating that after an engine failure, prolonged operation at high thrust settings on the remaining engine during an ETOPS diversion may result in failure of the remaining engine before the diversion can be safely completed. We are issuing this AD to address the unsafe condition on these products.

This action proposes to amend Class E airspace extending upward from 700 feet above the surface at Capital Region International Airport, Lansing, MI. The FAA is proposing this action as a result of an airspace review do to the decommissioning of the Lansing VHF omnidirectional range (VOR) navigation aid as part of the VOR Minimum Operational Network (MON) Program. The geographic coordinates and name of the airport would also be updated to coincide with the FAA's aeronautical database. An editorial change would also be made to the legal designation by removing the city from the airport name.

We propose to adopt a new airworthiness directive (AD) for all General Electric Company (GE) CF34-8E turbofan engines. This proposed AD was prompted by a report from GE regarding a quality escape of nonconforming thrust reverser fire seals. This proposed AD would require a one-time inspection of the gap between the core cowl seal and the pylon seal of the thrust reverser for correct gap width, and replacement of the seals, if needed. We are proposing this AD to address the unsafe condition on these products.

We propose to adopt a new airworthiness directive (AD) for 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. This proposed 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 proposed AD would require identifying the BDDV part number installed on the airplane, and modifying or replacing BDDVs having certain part numbers. We are proposing this AD to address the unsafe condition on these products.

We propose to supersede Airworthiness Directive (AD) 2017-15- 17, which applies to certain Airbus Model A300 B4-600R series airplanes, Model A300 C4-605R Variant F airplanes, and Model A300 F4- 600R series airplanes. AD 2017-15-17 requires an inspection of the lower area of a certain frame radius for cracking, and corrective action if necessary. Since we issued AD 2017-15-17, we have determined that repetitive inspections and applicable corrective actions are necessary. This proposed AD would add new repetitive inspections of the lower area of a certain frame radius for cracking, and corrective actions if necessary. We are proposing this AD to address the unsafe condition on these products.
