Word document. Recognizing the importance of visual inspection in the maintenance of the civil air fleet, the FAA tasked the Aging Aircraft Nondestructive Inspection Validation Center (AANC) at Sandia National Labs in Albuquerque, NM, to establish a visual inspection reliability program. This report presents the results of the first phase of that p

The Icing Technology Branch at NASA Lewis has been involved in an effort to validate two thermal ice protection codes developed at the NASA Lewis Research Center: LEWICE/Thermal 1 (electrothermal de-icing and anti-icing), and ANTICE 2 (hot gas and electrothermal anti-icing). The thermal code validation effort was designated a priority during a 1994

This amendment supersedes AD 93-19-06, which currently requires repetitively inspecting acrylic cabin and cockpit side windows for cracks on certain Fairchild Aircraft SA26, SA226, and SA227 series airplanes, and, if cracks are found that exceed certain limitations, replacing that window. This action maintains the requirement of repetitively inspec

Seasonal variations in climatic conditions have long been recognized to have a significant impact on the structural response of flexible pavements. Of particular significance is the effect of subgrade moisture content on subgrade support values and potential roadway damage. The Montana Department of Transportation is conducting a project to evaluat

This research has shown that a Grade 70 construction steel of 1/2- to 1-inch plate thicknesses can be produced without a quench and temper or accelerated cooling from hot-rolling if the Cu content in the steel is sufficiently high. Coherent very fine bcc Cu precipitates form on air cooling providing strengthening to at least 70 Ksi. The yield stren

The program standard is intended to serve as a common rational basis upon which the pipeline industry and its regulators can interactively develop, assess, and refine effective risk management programs and proposals. It is not intended to provide a detailed instruction manual that can be followed by rote by pipeline companies to develop a program o

Urban areas considering major transportation investments evaluate alternatives using various techniques such as benefit-cost analysis and cost effectiveness measures. A comprehensive benefit-cost analysis is the least biased method of judging project merit when cross-modal impacts are significant. Using Oklahoma City data, five build alternatives i

Field monitoring and numerical modeling were conducted to assess the hydraulic feasibility of the Southwest (SW) Corner Cut proposed to be opened in East Matagorda Bay, Texas, for enhancing water exchange. The SW Corner Cut would be the third inlet in East Matagorda Bay. The two existing inlets are the flood-relief channel called Mitchell's Cut, lo

The Federal Aviation Administration (FAA), within the Department of Transportation (DOT), is responsible for promoting safety in civil air transportation. General Accounting Office (GAO) and DOT's Office of Inspector General review FAA's safety programs, and the National Transportation Safety Board (NTSB) investigates aviation accidents. The three

This amendment adopts a new airworthiness directive (AD), applicable to Hartzell Propeller Inc. (Hartzell) HC-A3V, HC-B3M, HC-B3T, HC-B4M, HC-B4T, and HC-B5M series propellers, that requires hub replacement over a 10-year time period with a concurrent blade and blade clamp inspection. This amendment is prompted by reports of two propeller hub failu

In mid-October 1994, major flooding occurred in the San Jacinto River flood plain near Houston, Texas. Due to the flooding, 8 pipelines ruptured and many others were undermined. Ignition of petroleum and petroleum products released into the river resulted in 574 people receiving (mostly minor) burn and inhalation injuries. The Safety Board undertoo
