Railroad Cost Recovery Procedures-Productivity Adjustment
In a decision served on February 14, 2017, the Surface Transportation Board tentatively adopted 1.020 (2.0% per year) as the measure of average change in railroad productivity for the 2011-2015 (five-year) averaging period. This value represents an increase of 0.6% from the average for the 2010-2014 period. Because of the unique circumstances of this year's productivity adjustment calculation, including the proposal of a linking factor to address a change in methodology in the calculation of an input to the productivity adjustment, the Board is making its productivity adjustment tentative to allow public comment on this approach. The Board will hold a technical conference with interested parties and Board staff.
Notice of Final Federal Agency Action on State Highway 99 (Grand Parkway) Segment B, From SH 288 to Interstate Highway (IH) 45 South, Brazoria and Galveston Counties, Texas
This notice announces actions taken by TxDOT and Federal agencies that are final within the meaning of 23 U.S.C. 139(l)(1). The environmental review, consultation, and other actions required by applicable Federal environmental laws for this project are being, or have been, carried-out by TxDOT pursuant to 23 U.S.C. 327 and a Memorandum of Understanding dated December 16, 2014 and executed by FHWA and TxDOT. The actions relate to a proposed highway project, State Highway 99 (Grand Parkway) Segment B, from SH 288 to IH 45 South, in Brazoria and Galveston Counties in the State of Texas. Those actions grant licenses, permits, and approvals for the project. Under MAP-21 section 1319, TxDOT has issued a separate Final Environmental Impact Statement (FEIS) and Record of Decision (ROD) for this action.
Airworthiness Directives; Airbus Airplanes
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 is intended to complete certain mandated programs intended to support the airplane reaching its limit of validity (LOV) of the engineering data that support the established structural maintenance program. This proposed AD would require inspecting the forward passenger doors to identify the part number, and for affected doors, inspecting to identify existing repairs and corrective actions if necessary. We are proposing this AD to address the 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 429 helicopters. This proposed AD would require adding an identification number to life- limited rod ends that do not have a serial number (S/N). The proposed actions are intended to address an unsafe condition on these products.
Airworthiness Directives; Airbus Helicopters Deutschland GmbH Helicopters
We propose to adopt a new airworthiness directive (AD) for Airbus Helicopters Deutschland GmbH (Airbus Helicopters) Model MBB-BK 117 C-2 (including configuration C-2e) and MBB-BK 117 D-2 helicopters. This proposed AD would require replacing the main rotor (M/R) blade vibration absorbers. This proposed AD is prompted by a report of strong M/R blade vibrations on a Model MBB-BK 117 C-2 helicopter. The proposed actions are intended to prevent an unsafe condition on these products.
Airworthiness Directives; Romtex Anjou Aeronautique (Romtex) Torso Restraint Systems
We propose to adopt a new airworthiness directive (AD) for Romtex torso restraint systems (restraint systems) installed on but not limited to Airbus Helicopters Model AS350B2, AS350B3, EC130B4, EC130T2, and AS355NP helicopters. This proposed AD would require replacing certain restraint system buckles. This proposed AD is prompted by a report of several restraint system buckle knobs breaking. The proposed actions are intended to correct an unsafe condition on these products.
Airworthiness Directives; British Aerospace Regional Aircraft Airplanes
We propose to adopt a new airworthiness directive (AD) for British Aerospace Regional Aircraft Model HP 137 Jetstream MK1, Jetstream Series 200, and Jetstream Series 3101 airplanes that would supersede AD 2014-07-07. This proposed 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 cracking of the forward main landing gear yoke pintle resulting from corrosion pits leading to stress corrosion cracking. We are issuing this proposed AD to require actions to address the unsafe condition on these products.
