Department of Transportation June 13, 2007 – Federal Register Recent Federal Regulation Documents

This document proposes superseding an existing airworthiness directive (AD) for the specified Eurocopter France (ECF) model helicopters. That AD currently requires a onetime inspection for end play in the pitch control rod assembly double bearing (bearing) using the tail rotor (T/R) hub control plate, and before further flight, replacing the bearing if end play is present. This action would require checking the T/R gearbox (TGB) oil level before the first flight of the day and maintaining the oil at the maximum level for certain helicopters. Also, this action would require, during each required inspection or at certain specified intervals, ensuring the oil is at the maximum level for certain other model helicopters. Also, this action would require inspecting the magnetic plug for chips at specified intervals. Depending on the quantity of chips found, this action would require either replacing the TGB before further flight or further inspecting for axial play in the T/R hub pitch change control spider (spider). If axial play is found in the spider, before further flight, this AD would require replacing the bearing. This proposal is prompted by the finding that metal chips were not detected on the magnetic plug due to insufficient oil flow because the oil in the TGB was being maintained at the minimum level. The actions specified by the proposed AD are intended to detect metal chips on the magnetic plug, to prevent damage to the bearing resulting in end play, loss of T/R pitch control, and subsequent loss of control of the helicopter.

The Federal Transit Administration invites public comments about our intention to request the Office of Management and Budget's (OMB) approval to renew the following information collection: Pre-Award and Post-Delivery Review Requirements. The information to be collected for this program is necessary to certify that pre-award and post- delivery reviews will be conducted when using FTA funds to purchase revenue service vehicles. The Federal Register Notice with a 60-day comment period soliciting comments was published on April 3, 2007.

FMCSA announces its decision to exempt 24 individuals from the vision requirement in the Federal Motor Carrier Safety Regulations (FMCSRs). The exemptions will enable these individuals to operate commercial motor vehicles (CMVs) in interstate commerce without meeting the prescribed vision standard. The Agency has concluded that granting these exemptions will provide a level of safety that is equivalent to, or greater than, the level of safety maintained without the exemptions for these CMV drivers.
