Department of Transportation January 12, 2010 – Federal Register Recent Federal Regulation Documents

We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) originated 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: * * * * *

The FAA is revising an existing airworthiness directive (AD), which applies to certain Model 737-600, -700, -700C, -800, and -900 series airplanes. That AD currently requires revising the Airworthiness Limitations (AWLs) section of the Instructions for Continued Airworthiness by incorporating new limitations for fuel tank systems to satisfy Special Federal Aviation Regulation No. 88 requirements. That AD also requires an initial inspection to phase in certain repetitive AWL inspections, and repair if necessary. This AD clarifies the intended effect of the AD on spare and on-airplane fuel tank system components. This AD results from a design review of the fuel tank systems. We are issuing this AD to prevent the potential for ignition sources inside fuel tanks caused by latent failures, alterations, repairs, or maintenance actions, which, in combination with flammable fuel vapors, could result in a fuel tank explosion and consequent loss of the airplane.

We propose to adopt a new airworthiness directive (AD) for the products listed above that would supersede an existing AD. This proposed AD results from mandatory continuing airworthiness information (MCAI) originated 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: In 1991, the UK Civil Aviation Authority (CAA) issued AD 015-08-91 [which corresponds to FAA AD 93-01- 11], requiring the accomplishment of inspections of, and in case of crack findings, corrective actions on, the wing top skin at rib `0' of pre-modification HCM00851C BAe 146 series aircraft in accordance with British Aerospace Service Bulletin (SB) 57-41 dated 26 July 1991. Recently, BAE Systems (Operations) Ltd has determined that a revised inspection programme for the wing top skin and joint strap at rib `0' on all BAe 146 and AVRO 146-RJ aircraft is necessary to assure the continued structural integrity of this area. Cracking of the wing centre section top skin, if undetected, could lead to structural failure and consequent loss of the aircraft.

Using data from Management Information System annual reports, FRA has determined that the 2008 rail industry random testing positive rates were 0.46 percent for drugs and 0.15 percent for alcohol. Because the industry-wide random drug testing positive rate has remained below 1.0 percent for the last two years of data, the Federal Railroad Administrator (Administrator) has determined that the minimum annual random drug testing rate for the period January 1, 2010, through December 31, 2010, will remain at 25 percent of covered railroad employees. In addition, because the industry-wide random alcohol testing violation rate has remained below 0.5 percent for the last two years, the Administrator has determined that the minimum random alcohol testing rate will remain at 10 percent of covered railroad employees for the period January 1, 2010, through December 31, 2010.

This document announces receipt by the National Highway Traffic Safety Administration (NHTSA) of a petition for a decision that 2001 and 2002 Ducati MH900e motorcycles that were not originally manufactured to comply with all applicable Federal Motor Vehicle Safety Standards (FMVSS) are eligible for importation into the United States because they are substantially similar to vehicles that were originally manufactured for sale in the United States and that were certified by their manufacturer as complying with the safety standards, and they are capable of being readily altered to conform to the standards.

This document makes a correction to a Final special conditions; request for comment document, published in the Federal Register on June 5, 2009 (74 FR 26946), which issued special conditions for the Bombardier, Inc., Model DHC-8-100, -200, -300, and -400 series airplanes, for passenger seats with non-traditional, large, non- metallic panels. The Final special conditions; request for comment document, included an incorrect Special Conditions number.
