Federal Aviation Administration April 18, 2006 – Federal Register Recent Federal Regulation Documents

The FAA proposes to adopt a new airworthiness directive (AD) for certain Boeing Model 737-100, -200, -200C, -300, -400, and -500 series airplanes. This proposed AD would require repetitive inspections to detect cracks in the vertical beam webs of the body station (BS) 178 bulkhead, and corrective actions if necessary. This proposed AD also would require a terminating modification for the repetitive inspections. This proposed AD results from reports of numerous cracks in the vertical beam webs. We are proposing this AD to prevent fatigue cracks in certain vertical beam webs, which could result in loss of structural integrity of the BS 178 bulkhead, and consequently could impair the operation of the control cables for the elevators, speed brakes, and landing gear, or could cause the loss of cabin pressure.

This document confirms the effective date of the direct final rule which revises Class E airspace at Scott City, KS.

The Federal Aviation Administration (FAA) announces its findings on the noise compatibility program submitted by the Niagara Frontier Transportation Authority (NFTA) under the provisions of 49 U.S.C. (the Aviation Safety and Noise Abatement Act, hereinafter referred to as ``the Act'') and 14 CFR Part 150. These findings are made in recognition of the description of Federal and nonfederal responsibilities in Senate Report No. 96-52 (1980). On September 7, 2005 the FAA determined that the noise exposure maps submitted by the Niagara Frontier Transportation Authority under Part 150 were in compliance with applicable requirements. On March 3, 2006, the FAA approved Buffalo Niagara International Airport's noise compatibility program. Most of the recommendations of the program update were approved. Four measures were disapproved for Part 150 purposes.
