Airworthiness Directives; Bombardier, Inc. Airplanes
We propose to adopt a new airworthiness directive (AD) for certain Bombardier, Inc. Model CL-600-1A11 (CL-600), CL-600-2A12 (CL- 601), and CL-600-2B16 (CL-601-3A, CL-601-3R, and CL-604 Variants) airplanes. This proposed AD was prompted by a determination that the forward lugs of the flap hinge box might not conform to engineering drawings, which could result in premature fatigue cracking. This proposed AD would require revising the maintenance or inspection program to include new airworthiness limitations tasks; and measuring the forward lug edge distance of each flap hinge box, and inspecting for cracking and damage (i.e., deformation or bearing failure) of the forward lug edge of each flap hinge box, and repair if necessary. We are proposing this AD to detect and correct non-conforming flap hinge box forward lugs, which could result in failure of the lugs and detachment of the flap hinge box and consequent detachment of the flap surface.
Airworthiness Directives; Fokker Services B.V. Airplanes
We propose to adopt a new airworthiness directive (AD) for all Fokker Services B.V. Model F.28 Mark 0070 and 0100 airplanes. This proposed AD was prompted by a report of two cases of heavy (hard to move) aileron control caused by aileron cables stuck in a clump of ice in the wheel bay. This proposed AD would require installing drain tubes on the center wing rear spar. We are proposing this AD to prevent accumulated water near or on the aileron control cables, which could freeze and result in reduced control of the airplane.
Airworthiness Directives; Bombardier, Inc. Airplanes
We propose to adopt a new airworthiness directive (AD) for certain Bombardier, Inc. Model CL-600-2B19 (Regional Jet Series 100 & 440) airplanes. This proposed AD was prompted by a report indicating that inboard and outboard hydraulic lines of the brakes were found connected to the incorrect ports on the swivel assembly of the main landing gear (MLG). This proposed AD would require modifying the MLG by installing a new bracket on the left and right lower aft-wing planks. We are proposing this AD to prevent incorrect installation of the brake hydraulic lines, which could cause the brakes and the anti-skid system to operate incorrectly, and cause catastrophic failure of the airplane during a high-speed rejected takeoff.
Information Collection Activities: Submission for the Office of Management and Budget (OMB) Review; Request for Comment
In compliance with the Paperwork Reduction Act of 1995 (44 U.S.C. chapter 35), this notice announces that the Information Collection Request (ICR) abstracted below will be submitted to the Office of Management and Budget (OMB) for review. The ICR describes the nature of the information collection and its expected burden. A Federal Register Notice with a 60-day comment period soliciting public comments on the following information collection was published on April 30, 2014 (Federal Register/Vol. 79, No. 83/pp. 24494-24495).
Environmental Impact Statement: Northwest Corridor Project-Municipalities of Hatillo, Camuy, Quebradillas, Isabela, Moca and Aguadilla, Commonwealth of Puerto Rico
The FHWA is issuing this notice to advise the public that an environmental impact statement (EIS) will be prepared for a proposed Northwest Corridor highway project within the Municipalities of Hatillo, Camuy, Quebradillas, Isabela, Moca and Aguadilla in the Commonwealth of Puerto Rico.
Airworthiness Directives; Sikorsky Aircraft Corporation Helicopters
We are adopting a new airworthiness directive (AD) for the Sikorsky Aircraft Corporation (Sikorsky) Model S-92A helicopter. This AD requires revising the Rotorcraft Flight Manual (RFM) to include the appropriate operating limitations for performing Class D external load- combination operations. This AD was prompted by an inaccurate RFM provision, which was approved without appropriate limitations for this model helicopter for carrying Class D external rotorcraft-load combinations, including human external cargo (HEC). The actions are intended to require appropriate operating limitations to allow operators to perform Class D external load-combination operations, including HEC, in this model helicopter that now meets the Category A performance standard.
Congestion Mitigation and Air Quality Improvement (CMAQ) Program
The CMAQ program provides funding to State and local governments for transportation projects and programs to help meet the requirements of the Clean Air Act (CAA). Funding is available to reduce congestion and improve air quality for areas that do not meet the National Ambient Air Quality Standards (NAAQS) for ozone, carbon monoxide (CO), or particulate matter (nonattainment areas) and for areas that were out of compliance but have now met the standards (maintenance areas). The Moving Ahead for Progress in the 21st Century Act (MAP-21) requires priority use of CMAQ funds in areas that are designated nonattainment or maintenance for fine particulate matter (PM2.5) NAAQS under the CAA. Specifically, an amount equal to 25 percent of the CMAQ funds apportioned to each State for a nonattainment or maintenance area that is based all or in part on the weighted population of the PM2.5 nonattainment area shall be obligated to projects that reduce PM2.5 emissions in such area. These projects include diesel retrofits for on-road and some off- road applications, as well as for diesel equipment operated on a highway construction project within PM2.5 nonattainment and maintenance areas. Although the MAP-21 language for the CMAQ funds that must be obligated for PM2.5 projects (referred to in this NPRM as a ``set-aside'') instructs that the set-aside be calculated based on ``weighted population'' for PM2.5, the statute does not specify the values to be applied to determine the weighted population. In this proposed rule, FHWA is requesting comments on a proposed weighting factor of 5, to be used in determining the weighted population of a PM2.5 nonattainment area.
