Airworthiness Directives; General Electric Company Turbofan Engines
We propose to adopt a new airworthiness directive (AD) for certain General Electric Company (GE) GE90-110B1 and -115B turbofan engines. This proposed AD was prompted by multiple events of a leaking variable bypass valve (VBV) actuator fuel supply tube. This proposed AD would require replacement of this VBV actuator fuel supply tube with a part eligible for installation. We are proposing this AD to prevent failure of the affected fuel supply tube, fuel leakage, engine fire, and damage to the airplane.
Airworthiness Directives; Turbomeca S.A. Turboshaft Engines
We propose to adopt a new airworthiness directive (AD) for all Turbomeca S.A. Arrius 2B1, 2B1A, 2B2, and 2K1 turboshaft engines. This proposed AD was prompted by in-flight shutdowns caused by interrupted fuel supply at the hydro-mechanical metering unit (HMU). This proposed AD would require initial and repetitive inspections of the HMU high pressure pump drive gear shaft splines, cleaning and inspections of the sleeve assembly splines, and replacement of the HMU if it fails inspection. We are proposing this AD to prevent in-flight shutdown and damage to the engine.
IFR Altitudes; Miscellaneous Amendments
This amendment adopts miscellaneous amendments to the required IFR (instrument flight rules) altitudes and changeover points for certain Federal airways, jet routes, or direct routes for which a minimum or maximum en route authorized IFR altitude is prescribed. This regulatory action is needed because of changes occurring in the National Airspace System. These changes are designed to provide for the safe and efficient use of the navigable airspace under instrument conditions in the affected areas.
Pilot Certification and Qualification Requirements for Air Carrier Operations; Correction
The FAA is correcting a final rule published on July 15, 2013 (78 FR 42324). In that rule, which became effective on July 15, 2013, the date of publication, the FAA amended its regulations to create new certification and qualification requirements for pilots in air carrier operations. This document corrects errors in the regulatory text of that document.
Airworthiness Directives; Bombardier, Inc. Airplanes
We are adopting a new airworthiness directive (AD) for all Bombardier, Inc. Model CL-600-2B19 (Regional Jet Series 100 & 440), CL- 600-2C10 (Regional Jet Series 700, 701, & 702), CL-600-2D15 (Regional Jet Series 705), and CL-600-2D24 (Regional Jet Series 900) airplanes. This AD requires revising the airplane flight manual (AFM) by incorporating an emergency procedure for uncommanded yaw motion. This AD was prompted by reports of airplanes experiencing uncommanded rudder movements while in flight. We are issuing this AD to advise the flightcrew of procedures to address a possible failure of the voltage regulator inside the yaw damper actuator that could lead to uncommanded yaw movement and consequent loss of the ability to control the airplane.
