Department of Transportation November 12, 2015 – Federal Register Recent Federal Regulation Documents

We are adopting a new airworthiness directive (AD) for all General Electric Company (GE) GEnx-1B turbofan engine models. This AD was prompted by reports of GEnx-1B engine oil loss. This AD requires removal and replacement of the non-conforming ball valve in the oil filler cap. We are issuing this AD to prevent loss of engine oil, which could lead to failure of one or more engines, loss of thrust control, and damage to the airplane.

FMCSA announces receipt of applications from 54 individuals for exemption from the prohibition against persons with insulin-treated diabetes mellitus (ITDM) operating commercial motor vehicles (CMVs) in interstate commerce. If granted, the exemptions would enable these individuals with ITDM to operate CMVs in interstate commerce.

In accordance with the Paperwork Reduction Act of 1995, the Department of Transportation's (DOT) Office of the Secretary (OST) announces its plan to submit the Information Collection Request (ICR) described below to the Office of Management and Budget (OMB) for its review and approval and invites public comment. Executive Order 12862 directs Federal agencies to provide service to the public that matches or exceeds the best service available in the private sector. In order to work continuously to ensure that our programs are effective and meet our customers' needs, the Department of Transportation (DOT) seeks to obtain OMB approval of a generic clearance to collect feedback on our service delivery.

: FRA is issuing this notice to advise the public that it intends to grant Amtrak a waiver from FRA's Buy America policy for the use of eight components of Tier III high-speed rail (HSR) trainsets.

We propose to adopt a new airworthiness directive (AD) for all BAE Systems (Operations) Limited Model BAe 146 series airplanes and Model Avro 146-RJ series airplanes. This proposed AD was prompted by reports of cracking of the main fitting of the nose landing gear (NLG) and a determination that a new safe-life limitation for affected NLG main fittings has not been mandated. This proposed AD would require replacing affected NLG main fittings that have exceeded the safe-life limitation with a new or serviceable fitting. We are proposing this AD to prevent collapse of the NLG, which if not corrected, could lead to degradation of direction control on the ground or an un-commanded turn to the left, and a consequent loss of control of the airplane on the ground, possibly resulting in damage to the airplane and injury to occupants.

We propose to adopt a new airworthiness directive (AD) for all Airbus Model A330-200, -200 Freighter, and -300 series airplanes; and all Airbus Model A340-200, -300, -500, and -600 series airplanes. This proposed AD was prompted by a report of blockage of Angle of Attack (AOA) probes during climb, leading to activation of the Alpha Protection (Alpha Prot) while the Mach number increased. This activation could cause a continuous nose-down pitch rate that cannot be stopped with backward sidestick input, even in the full backward position. For certain airplanes, this proposed AD would require replacing certain AOA sensors (probes) with certain new AOA sensors. For certain other airplanes, this proposed AD would also require inspections and functional heat testing of certain AOA sensors for discrepancies, and replacement if necessary. We are proposing this AD to prevent erroneous AOA information and Alpha Prot activation due to blocked AOA probes, which could result in a continuous nose-down command and consequent loss of control of the airplane.

We are superseding Airworthiness Directive (AD) 2002-07-08 for certain The Boeing Company Model 737 airplanes. AD 2002-07-08 required repetitive inspections for cracking of the lower skin at the lower row of fasteners in the lap joints of the fuselage; repair of any cracking found; modification of the fuselage lap joints at certain locations, which terminated the repetitive inspections of the modified areas; and replacement of a certain preventive modification with an improved modification. This new AD adds repetitive inspections for cracking at certain window corner fastener holes, a preventive modification, and repair if necessary. This AD was prompted by the FAA's determination that certain modifications of the fuselage lap joints do not provide an adequate level of safety, and the subsequent discovery of cracks in additional fastener locations in the window belt skin panels, adjacent stringers, and window frames in locations outside the previous inspection area. We are issuing this AD to detect and correct fatigue cracking of the fuselage lap joints and window belt skin panels, which could result in reduced structural integrity and sudden decompression of the airplane.
