Airworthiness Directives; Boeing Model 767 Airplanes

Mon, Nov 27 2006 11:00:00 GMT

The FAA is adopting a new airworthiness directive (AD) for all Boeing Model 767 airplanes. This AD requires repetitive detailed and high frequency eddy current (HFEC) inspections of the station (STA) 1809.5 bulkhead for cracking and corrective actions if necessary. This AD results from fatigue cracks found in the forward outer chord and horizontal inner chord at STA 1809.5. We are issuing this AD to detect and correct cracking in the bulkhead structure at STA 1809.5, which could result in failure of the bulkhead structure for carrying the flight loads of the horizontal stabilizer, and consequent loss of controllability of the airplane.

Airworthiness Directives; Boeing Model 747 Airplanes

Mon, Nov 27 2006 11:00:00 GMT

The FAA is adopting a new airworthiness directive (AD) for certain Boeing Model 747 airplanes. This AD requires repetitive inspections for any cracking of the fuselage skin in section 41 of the airplane, and related investigative and corrective actions if necessary. This AD results from a report of fatigue cracks found in the skin in section 41 of the fuselage, on an inservice Model 747 airplane. We are issuing this AD to detect and correct fatigue cracks at the fastener rows of the fuselage skin in section 41, which could [[Page 68435]]
join together and cause a loss of structural integrity and rapid decompression of the airplane.

Amendment to Jet Route and Colored Federal Airways; Alaska

Mon, Nov 27 2006 11:00:00 GMT

This action amends Jet Route 510 (J-510), and Colored Federal Airways Amber 2 (A2), Amber 15 (A15), and Green 8 (G8), Alaska. Specifically, the FAA is redesignating J510 as J512 because of duplication with a Canadian Jet Route number, causing problems with the Flight Data processors during route validation at the Anchorage Air Route Traffic Control Center. Additionally, portions of A2, and A15, and G8 are discontinuous between fixes, causing flight processing software problems, and will be redesignated.

Portland & Western Railroad, Inc.--Acquisition and Operation Exemption--Union Pacific Railroad Company

Mon, Nov 27 2006 11:00:00 GMT

Portland & Western Railroad, Inc. (P&W), a Class III rail carrier, has filed a verified notice of exemption under 49 CFR 1150.41 to acquire a permanent, exclusive rail freight operating easement from Union Pacific Railroad Company (UP) to operate over an approximately 5 mile rail line between milepost 749.95 in Tigard, OR, and milepost 755.43 in
[[Page 68669]]
Beaverton, OR. Currently, P&W conducts local and overhead freight operations on the rail line pursuant to a lease with UP. The proposed transaction will change P&W's property interest in the rail line, but P&W will continue to operate over the line as the only common carrier providing rail freight service.

P&W has certified that its projected annual revenues as a result of this transaction will not exceed the annual revenues of a Class III railroad, but will exceed $5 million.

The transaction is scheduled to be consummated by no later than November 27, 2006.\1\
