Department of Transportation December 3, 2013 – Federal Register Recent Federal Regulation Documents

The FAA is issuing this notice to advise the public of a meeting of RTCA Program Management Committee.

Before a Federal agency can collect certain information from the public, it must receive approval from the Office of Management and Budget (OMB). Under procedures established by the Paperwork Reduction Act of 1995, before seeking OMB approval, Federal agencies must solicit public comment on proposed collections of information, including extensions and reinstatement of previously approved collections. This document describes one collection of information for which NHTSA intends to seek OMB approval.

We are adopting a new airworthiness directive (AD) for certain General Electric Company (GE) GE90-110B1 and -115B turbofan engines. This AD was prompted by multiple events of a leaking variable bypass valve (VBV) actuator fuel supply tube. This AD requires replacement of this VBV actuator fuel supply tube with a part eligible for installation. We are issuing this AD to prevent failure of the affected fuel supply tube, fuel leakage, engine fire, and damage to the airplane.

In compliance with the Paperwork Reduction Act of 1995 (44 U.S.C. 3501 et seq.), this notice announces that the Information Collection Requests (ICRs) abstracted below are being forwarded to the Office of Management and Budget (OMB) for review and comment. The ICRs describe the nature of the information collections and their expected burdens. The Federal Register notice with a 60-day comment period soliciting comments on the following collections of information was published on September 16, 2013 (78 FR 56995).

We are adopting a new airworthiness directive (AD) for Diamond Aircraft Industries GmbH Models DA40 and DA40F airplanes. This AD results from mandatory continuing airworthiness information (MCAI) issued 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 fatigue strength found in the aft main spar does not ensure unlimited lifetime structural integrity. We are issuing this AD to require actions to address the unsafe condition on these products.

We are adopting a new airworthiness directive (AD) for certain The Boeing Company Model 757 and Model 767 airplanes. This AD was prompted by a standby power relay failure and subsequent illumination of the ``STANDBY BUS OFF'' light, which led the flightcrew to set the standby power switch to the ``BAT'' position, isolating the battery and standby buses, disabling the battery charger, and eventually causing the main battery to be depleted. This AD requires doing wiring changes and installing a new air/ground relay to the battery charger system. We are issuing this AD to prevent discharge of the main battery, which could result in multiple system degradation, reduced airplane controllability, and runway excursion upon landing.

We are adopting a new airworthiness directive (AD) for certain The Boeing Company Model 707 airplanes; and Model 720 and 720B series airplanes. This AD was prompted by reports indicating that a standard access door was located where an impact-resistant access door was required, and stencils were missing from some impact-resistant access doors. This AD requires an inspection of the left- and right-hand wing fuel tank access doors to determine that impact-resistant access doors are installed in the correct locations, and to replace any door with an impact-resistant access door if necessary. This AD also requires an inspection for stencils and index markers on impact-resistant access doors, and application of new stencils or index markers if necessary. This AD also requires revising the maintenance program to incorporate changes to the airworthiness limitations section. We are issuing this AD to prevent foreign object penetration of the fuel tank, which could cause a fuel leak near an ignition source (e.g., hot brakes or engine exhaust nozzle), consequently leading to a fuel-fed fire.
