This AD also requires removing all affected blades from service and prohibits installing any affected blade on any helicopter. The FAA is issuing this AD to address the unsafe condition on these products.
Agency Information Collection Activities: Request for Comments; Clearance of a New Approval of Information Collection: Formal Complaints Collection
In accordance with the Paperwork Reduction Act of 1995, FAA invites public comments within 30 days after the date of publication of this notice about its intention to request the Office of Management and Budget (OMB) approval for an existing information collection.

Airworthiness Directives; Airbus SAS Airplanes
The FAA is correcting an airworthiness directive (AD) that was published in the Federal Register. That AD applies to certain Airbus SAS Model A318-111, -112, and -122 airplanes; Model A319-111, -112, - 113, -114, -115, -131, -132, and -133 airplanes; and Model A320-211, - 212, -214, -231, -232, and -233 airplanes. As published, the AD number specified in the preamble and regulatory text is incorrect. This document corrects this error. In all other respects, the original document remains the same.
Amendment of Class E Airspace; Pocahontas, IA
This action amends the Class E airspace extending upward from 700 feet above the surface at Pocahontas Municipal Airport, Pocahontas, IA. This action is the result of an airspace review due to the decommissioning of the Pocahontas non-directional beacon (NDB). Additionally, the geographical coordinates of the airport are also being updated to coincide with the FAA's aeronautical database, which was inadvertently omitted in the NPRM docket.
Airworthiness Directives; Safran Helicopter Engines, S.A. (Type Certificate Previously Held by Turbomeca S.A.) Turboshaft Engines
The FAA is superseding Airworthiness Directive (AD) 2014-04-06 for all Safran Helicopter Engines, S.A. (Safran Helicopter Engines) Arrius 2B1, 2B1A, 2B2, and 2K1 model turboshaft engines. AD 2014-04-06 required initial and repetitive inspections of the hydro-mechanical metering unit (HMU) high-pressure pump drive gear shaft splines, cleaning and inspections of the sleeve assembly splines, and replacement of the sleeve assembly on the affected high-pressure pump drive gear shaft or replacement of the HMU if the HMU fails inspection. This AD was prompted by in-flight shutdowns caused by interrupted fuel supply at the HMU. This AD requires revised inspections and continues to require cleaning of the sleeve assembly splines, and replacement of the sleeve assembly on the affected high-pressure pump drive gear shaft or replacement of the HMU if the HMU fails an inspection. The FAA is issuing this AD to address the unsafe condition on these products.
Revocation of Class E Airspace; Red Hook, NY
This action removes Class E airspace in Red Hook, NY, as Skypark Airport has been abandoned, and controlled airspace is no longer required. This action would enhance the safety and management of controlled airspace within the national airspace system.
Airworthiness Directives; Rolls-Royce Deutschland Ltd & Co KG (Type Certificate Previously Held by Rolls-Royce plc) Turbofan Engines
The FAA is adopting a new airworthiness directive (AD) for certain Rolls-Royce Deutschland Ltd & Co KG (RRD) Trent XWB-75, Trent XWB-79, Trent XWB-79B, and Trent XWB-84 model turbofan engines. This AD was prompted by reports of cracks in the intermediate-pressure compressor (IPC) rotor 1 (R1) blades installed on certain Trent XWB model turbofan engines. This AD requires initial and repetitive borescope inspections (BSIs) of the affected IPC R1 blades and, depending on the results of the inspections, replacement of all 34 IPC R1 blades. The FAA is issuing this AD to address the unsafe condition on these products.
Proposed Amendment of Class E Airspace; Galesburg, IL
This action proposes to amend the Class E airspace at Monmouth Municipal Airport, Monmouth, IL, contained within the Galesburg, IL, airspace legal description. The FAA is proposing this action as the result of airspace reviews caused by the decommissioning of the Galesburg very high frequency (VHF) omnidirectional range (VOR) as part of the VOR Minimal Operational Network (MON) Program.
Amendment of Class E Airspace; Malden, MO
This action amends Class E airspace extending upward from 700 feet above the surface at Malden Regional Airport, (formerly Malden Municipal Airport), Malden, MO. The FAA is taking this action as a result of an airspace review caused by the decommissioning of the Malden Very High Frequency Omni-Directional Range (VOR) co-located with Tactical Air Navigation (TACAN) which equates to a (VORTAC) navigation aid as part of the VOR Minimum Operational Network (MON) Program. Controlled airspace is necessary for the safety and management of instrument flight rules (IFR) in the area.
Airworthiness Directives; Bell Textron Canada Limited Helicopters
The FAA is adopting a new airworthiness directive (AD) for certain Bell Textron Canada Limited Model 429 helicopters. This AD was prompted by three reports of unexpected forces or uncommanded inputs to the directional (yaw) control system. This AD requires revising the existing Rotorcraft Flight Manual (RFM) for your helicopter. The FAA is issuing this AD to address the unsafe condition on these products.
Airworthiness Directives; Hélicoptères Guimbal Helicopters
The FAA is adopting a new airworthiness directive (AD) for H[eacute]licopt[egrave]res Guimbal Model Cabri G2 helicopters with any metal bushing installed on the main rotor (M/R) swashplate guide bellcrank. This AD was prompted by a report of cracks discovered on the M/R scissor link during scheduled maintenance on several helicopters. This AD requires removing all metal bushings from service, visually inspecting the lug bore area and depending on the inspection results, removing certain parts from service and installing certain part- numbered plastic bushings. This AD also prohibits installing any metal bushing on any helicopter. The FAA is issuing this AD to address the unsafe condition on these products.
Airworthiness Directives; Airbus Helicopters
The FAA is revising a supplemental notice of proposed rulemaking SNPRM that applied to certain Airbus Helicopters Model EC225LP helicopters. This action revises the SNPRM by proposing to require the installation of an improved part, which would also provide a terminating action for the proposed requirements. The FAA is proposing this airworthiness directive (AD) to address the unsafe condition on these products. Since these actions would impose an additional burden over those in the SNPRM, the agency is requesting comments on this SNPRM.
