Historic Preservation, Advisory Council July 30, 2015 – Federal Register Recent Federal Regulation Documents

FMCSA confirms its decision to exempt 51 individuals from its rule prohibiting persons with insulin-treated diabetes mellitus (ITDM) from operating commercial motor vehicles (CMVs) in interstate commerce. The exemptions enable these individuals to operate CMVs in interstate commerce.

This notice sets forth the reasons for the denial of a petition, DP14-004, submitted by the Center for Auto Safety (the petitioner) to the Administrator of NHTSA by a letter dated August 21, 2014, under 49 CFR part 552. The petition requests the agency to initiate a safety defect investigation into alleged failures of Totally Integrated Power Modules (TIPMs) installed in sport utility vehicles, trucks, and vans built by Chrysler FCA (Chrysler) beginning in the 2007 model year. The petitioner alleges that TIPM defects may result in the following safety defect conditions: Engine stall, airbag non- deployment, failure of fuel pump shutoff resulting in unintended acceleration, and fire. After conducting a technical review of: (1) Consumer complaints and other material submitted by the petitioner; (2) information provided by Chrysler in response to information requests regarding TIPM design, TIPM implementation and the complaints submitted by the petitioner; and (3) Chrysler safety recalls 14V-530 and 15V-115 addressing a fuel pump relay defect condition that may result in engine stall while driving in certain vehicles equipped with TIPM body control modules; and the likelihood that additional investigations would result in a finding that a defect related to motor vehicle safety exists, NHTSA has concluded that further investigation of the issues raised by the petition is not warranted. The agency, accordingly, has denied the petition.

In compliance with the Paperwork Reduction Act of 1995 (44 U.S.C. 3501 et seq.), this notice announces that the Information Collection Request (ICR) abstracted below has been forwarded to the Office of Management and Budget (OMB) for review and comment. The ICR describes the nature of the information collections and their expected burden. The Federal Register Notice with a 60-day comment period was published on January 2, 2015 [80 FR 99].

We propose to supersede Airworthiness Directive (AD) 2012-17- 13, which applies to certain The Boeing Company Model 707 airplanes, and Model 720 and 720B series airplanes. For certain airplanes, AD 2012-17-13 required using redefined flight cycle counts; determining the type of material of the horizontal stabilizer, rear spar, and upper and lower chords on the inboard and outboard ends of the rear spar; repetitively inspecting for cracking of the horizontal stabilizer components; and repairing or replacing the chord, or modifying chord segments made of 7079 aluminum, if necessary. For all airplanes, AD 2012-17-13 required inspecting certain structurally significant items, and repairing discrepancies if necessary. Since we issued AD 2012-17- 13, we have determined that all chord segments made of 7079 aluminum must be replaced with new, improved chord segments made of 7075 aluminum. This proposed AD would add a requirement to replace all chord segments made of 7079 aluminum with new, improved chord segments made of 7075 aluminum. We are proposing this AD to detect and correct stress corrosion and potential early fatigue cracking in the horizontal stabilizer, which could result in reduced structural integrity of the horizontal stabilizer.

We propose to adopt a new airworthiness directive (AD) for all Airbus Model A319-131, -132, and -133 airplanes; Model A320-232 and - 233 airplanes; and Model A321-131, -231, and -232 airplanes. This proposed AD was prompted by reports of forward engine mount attachment pins that were manufactured from discrepant raw material. This proposed AD would require identification and replacement of affected forward engine mount attachment pins. We are proposing this AD to prevent failure of a forward engine mount attachment pin, possible loss of an engine in-flight, and consequent reduced controllability of the airplane.
