Airworthiness Directives; Airbus Helicopters Deutschland GmbH Helicopters
We propose to adopt a new airworthiness directive (AD) for Airbus Helicopters Deutschland GmbH (Airbus Helicopters) Model EC135P1, EC135P2, EC135P2+, EC135P3, EC135T1, EC135T2, EC135T2+, and EC135T3 helicopters. This proposed AD would require replacing the retaining ring and inspecting the hoist cable hook assembly (hook). This proposed AD is prompted by a report that a hook detached from the hoist cable. The actions of this proposed AD are intended to prevent an unsafe condition on these products.
Airworthiness Directives; Rolls-Royce Deutschland Ltd & Co KG Turbofan Engines
We are adopting a new airworthiness directive (AD) for certain Rolls-Royce Deutschland Ltd & Co KG (RRD) BR700-710A2-20 and BR700- 710C4-11 turbofan engines. This AD was prompted by reports of deterioration of the intumescent heat resistant paint system on the electronic engine controller (EEC) firebox assembly that was found to be beyond acceptable limits. This AD requires replacement of affected EEC firebox assembly parts with improved parts, which have a more durable paint system. We are issuing this AD to address the unsafe condition on these products.
Airspace Designations; Incorporation by Reference
This action corrects a final rule published in the Federal Register of August 28, 2018, that amends Title 14 Code of Federal Regulations (14 CFR) part 71 relating to airspace designations to reflect the approval by the Director of the Federal Register of the incorporation by reference of FAA Order 7400.11C, Airspace Designations and Reporting Points. This action corrects the Airspace Designations and Reporting Points, signature date from August 8, 2017, to August 13, 2018.
Amendment of Air Traffic Service (ATS) Routes in the Vicinity of Mattoon and Charleston, IL
This action modifies two VHF Omnidirectional Range (VOR) Federal airways (V-72 and V-429) in the vicinity of Mattoon and Charleston, IL. The FAA is taking this action due to the planned decommissioning of the Mattoon, IL, VOR/Distance Measuring Equipment (VOR/DME) navigation aid (NAVAID), which provides navigation guidance for portions of the affected ATS routes. The Mattoon VOR is being decommissioned in support of the FAA's VOR Minimum Operational Network (MON) program.
Airworthiness Directives; Fokker Services B.V. Airplanes
We propose to adopt a new airworthiness directive (AD) for all Fokker Services B.V. Model F28 Mark 0070 and 0100 airplanes. This proposed AD was prompted by reports that debris from the parking brake shut off valve (PBSOV) could create a partial blockage of the restrictor check valve in the hydraulic return line of the PBSOV. This proposed AD would require replacing the restrictor check valve with an improved valve that has a filter screen. We are proposing this AD to address the unsafe condition on these products.
Airworthiness Directives; General Electric Company Turbofan Engines
We are adopting a new airworthiness directive (AD) for all General Electric Company (GE) GE90-76B, GE90-77B, GE90-85B, GE90-90B, and GE90-94B turbofan engines with full authority digital engine control (FADEC) software, version 22.214.171.124 or earlier, installed. This AD requires upgrading the FADEC software to a software version eligible for installation. This AD was prompted by an ice-crystal icing (ICI) event that caused damage to both engines, a single engine stall, and subsequent engine shutdown. We are issuing this AD to address the unsafe condition on these products.
Airworthiness Directives; International Aero Engines Turbofan Engines
We propose to adopt a new airworthiness directive (AD) for all International Aero Engines (IAE) PW1133G-JM, PW1133GA-JM, PW1130G-JM, PW1127G-JM, PW1127GA-JM, PW1127G1-JM, PW1124G-JM, PW1124G1-JM, and PW1122G-JM turbofan engines with certain low-pressure turbine (LPT) 1st- and 3rd-stage disks installed. This proposed AD was prompted by a report of manufacturing defects found on delivered LPT 1st- and 3rd- stage disks. This proposed AD would require removing the LPT 1st- or 3rd-stage disk from service and replacing with a part eligible for installation. We are proposing this AD to address the unsafe condition on these products.
