Book Description
On-demand operators have more risk in their operating environments and receive less oversight from FAA. For example, one on-demand operator we visited flew dozens of flights daily during the summer to take tourists to glaciers on which the aircraft landed and took off on skis. This operator flies 17 aircraft and was inspected 8 times by FAA in 2008. In contrast, a Part 121 operator with 10 aircraft, overseen by the same FAA oversight office, received 199 inspections in 2008. Industry and the National Transportation Safety Board (NTSB) have made recommendations to strengthen on-demand regulations. While FAA has made efforts to improve safety and adapt its oversight to the increased complexity of industry operations, it has not taken substantive action to address these recommendations. Further, FAA does not effectively target inspections to higher-risk on-demand operators. The number of fatalities from on-demand operations makes it imperative that FAA take action to address three issues we identified as it plans regulatory and oversight changes for the growing on-demand operator industry.

Book Description
If you are involved with machining or metalworking or you specify materials for industrial components, this book is an absolute must. It gives you detailed and comprehensive information about the selection, processing, and properties of materials for machining and metalworking applications. They include wrought and powder metallurgy tool steels, cobalt base alloys, cemented carbides, cermets, ceramics, and ultra-hard materials. You'll find specific guidelines for optimizing machining productivity through the proper selection of cutting tool materials plus expanded coverage on the use of coatings to extend cutting tool and die life. There is also valuable information on alternative heat treatments for improving the toughness of tool and die steels. All new material on the correlation of heat treatment microstructures and properties of tool steels is supplemented with dozens of photomicrographs. Information on special tooling considerations for demanding applications such as isothermal forging, die casting of metal matrix composites, and molding of corrosive plastics is also included. And you'll learn about alternatives to ferrous materials for metalworking applications such as carbides, cermets, ceramics, and nonferrous metals like aluminum, nickel, and copper base alloys.

Book Description
The book briefly describes the structure, properties and applications of various grades of steel, primarily aimed at non-metallurgical students from other engineering streams. The book consists of nine chapters covering most of the important types of steels and their physical metallurgy, microstructure and engineering applications including iron-carbon diagram, heat treatment, surface hardening methods, effect of alloying, specific applications, selection of materials, case studies and so forth. The book also contains subjective and objective questions aimed at exam preparation. Key Features Exclusive title aimed at introduction to steels for non-metallurgy audience Includes microstructure, composition, and properties of all the most commonly used steels Describes the heat treatments and the required alloying additions to process steel for the intended applications Discusses effects of alloying elements on steel Explores development of steels for specialized areas such as the automobile, aerospace, and nuclear industries
