Airworthiness Directives; Rolls-Royce plc Turbojet Engines
We are superseding Airworthiness Directive (AD) 2016-03-03 for all Rolls-Royce plc (RR) Viper Mk. 521, Viper Mk. 522, and Viper Mk. 601-22 turbojet engines. AD 2016-03-03 required reducing the life of certain critical parts. This AD requires reducing the life of certain critical parts and adds additional engine parts to the applicability. This AD was prompted by a determination made by RR that additional parts for the applicable RR Viper turbojet engine models are affected. We are issuing this AD to address the unsafe condition on these products.
Fixing America's Surface Transportation Act Correlation Study
On June 27, 2017, the National Academy of Sciences (NAS) published its report titled, ``Improving Motor Carrier Safety Measurement.'' This report was commissioned by FMCSA consistent with the requirements of Section 5221 of the Fixing America's Surface Transportation (FAST) Act. The FAST Act also requires that the Agency develop a corrective action plan to address any identified deficiencies and submit it to Congress and the U.S. Department of Transportation's (DOT) Office of Inspector General (OIG); this was completed on June 25, 2018. The purpose of this notice is to announce a public meeting to discuss NAS recommendations 2, 3 and 4 and to solicit input to be considered by the Agency.
Fees for the Unified Carrier Registration Plan and Agreement
FMCSA proposes reductions in the annual registration fees States collect from motor carriers, motor private carriers of property, brokers, freight forwarders, and leasing companies for the Unified Carrier Registration (UCR) Plan and Agreement for the 2019, 2020, and subsequent registration years. The proposed fees for the 2019 registration year would be reduced below the 2017 registration fee level that was in effect by approximately 17.59 percent to ensure that fee revenues do not exceed the statutory maximum, and to account for the excess funds held in the depository. The proposed fees for the 2020 registration year would be reduced below the 2017 level by approximately 9.5 percent. The reduction of the current 2019 registration year fees (finalized on January 5, 2018) would range from approximately $10 to $9,530 per entity, depending on the number of vehicles owned or operated by the affected entities. The reduction in fees for subsequent registration years would range from approximately $4 to $3,565 per entity.
Airworthiness Directives; Bell Helicopter Textron, Inc. (Bell) Helicopters
We are superseding Airworthiness Directive (AD) 2017-15-02 for Bell Model 212 and 412 helicopters. AD 2017-15-02 required replacing certain oil and fuel check valves and prohibited installing them on any helicopter. This AD retains the requirements of AD 2017-15-02 and adds certain model helicopters to the applicability. This AD was prompted by the discovery of an error in the affected models. We are issuing this AD to address the unsafe condition on these products.
Airworthiness Directives; Leonardo S.p.A. Helicopters
We propose to adopt a new airworthiness directive (AD) for Leonardo S.p.A. (Type Certificate Previously Held by Finmeccanica S.p.A., AgustaWestland S.p.A.) Model AW109SP helicopters. This proposed AD would require inspecting and altering the rescue hoist. This proposed AD is prompted by a report of a damaged hoist cable that detached after load application. The actions of this proposed AD are intended to address an unsafe condition on these products.
Airworthiness Directives; Bell Helicopter Textron Canada Limited Helicopters
We propose to adopt a new airworthiness directive (AD) for Bell Helicopter Textron Canada Limited (Bell) Model 206A, 206B, 206L, 206L-1, 206L-3, 206L-4, and 407 helicopters. This proposed AD would require inspecting and cleaning the oil supply restrictor (restrictor) to the freewheel assembly. This proposed AD is prompted by reports of a blocked oil line restrictor in the freewheel lubrication system. The proposed actions are intended to address an unsafe condition on these products.
Airworthiness Directives; Bombardier, Inc., Airplanes
We are superseding Airworthiness Directive (AD) 2014-05-28, which applied to certain Bombardier, Inc., Model DHC-8-400 series airplanes. AD 2014-05-28 required revising the maintenance or inspection program, as applicable. This AD requires revising the maintenance or inspection program, as applicable, to include a revised task. This AD was prompted by a determination that the interval from Maintenance Review Board (MRB) task number 323100-202 should not be escalated, and that Certification Maintenance Requirements (CMR) task number 323100-102 should be applicable to all Model DHC-8-400 series airplanes, regardless of which main landing gear (MLG) up-lock assembly is installed. We are issuing this AD to address the unsafe condition on these products.
