Book Description
This report presents the results of a study to develop airworthiness requirements for rotorcraft with external sling loads. The report starts with a review of the various phenomena that limit external sling load operations. Specifically discussed are the rotorcraft-load aeroservoelastic stability, load-on handling qualities, effects of automatic flight control system failure, load suspension system failure, and load stability at speed. Based on past experience and treatment of these phenomena, criteria are proposed to form a package for airworthiness qualification. The desired end objective is a set of operational flight envelopes for the rotorcraft with intended loads that can be provided to the user to guide operations in the field. The specific criteria proposed are parts of ADS-33E-PRF; MIL-F-9490D, and MIL-STD-913A all applied in the context of external sling loads. The study was performed for the Directorate of Engineering, U.S. Army Aviation and Missile Command (AMCOM), as part of the contract monitored by the Aerothermodynamics Directorate, U.S. Army AMCOM.

Book Description
This report summarizes the results of a joint NASA-FAA research program directed toward development of civil airworthiness flight-criteria for power-lift transports. Tentative criteria are proposed for performance and handling characteristics for powered-lift transport aircraft in commercial service. The aircraft considered are primarily wing-supported vehicles which rely upon the propulsion system for a significant portion of lift and control. VTOL aircraft are excluded. The flight criteria treat primarily the approach and landing flight phases, because it is in these flight phases that the greatest use of powered lift is made, and the greatest differences from conventional aircraft tend to appear. Consequently, the flight task tends to become most demanding. The tentative criteria are based on simulation and flight experience with a variety of powered-lift concepts. These concepts have not employed flight director, advanced displays, or advanced augmentation systems. The tentative criteria proposed were formulated by a working group comprised of representatives of the U.S., British, French, and Canadian airworthiness authorities, as well as research personnel of the NASA and other organizations. It is recognized that more work is needed to assure general applicability of the critera. (Author).

Book Description
Airworthiness: An Introduction to Aircraft Certification and Operations, Third Edition, once again proves to be a valuable, user-friendly reference guide for certification engineers engaged in professional training and practical work in regulatory agencies and aircraft engineering companies. The discussions reflect the recent changes in the EASA-FAA regulations and also include the concepts of flight safety and airworthiness; the ICAO and civil aviation authorities; airworthiness requirements; type certifications and the type-certification process; production of products, parts, and appliances; certifications of airworthiness; and rules for spaceworthiness. Since publication of the second edition, airworthiness regulation and certification around the world have gone through significant changes. For example, EASA structure has completely changed, FAA rules are no longer applicable, substantial changes have been made in the international airworthiness regulations and certification procedures, and unmanned aircraft have evolved technically and operationally. The changes in airworthiness regulations in the last five years have been striking, changing the way in which we look at airworthiness and certification processes around the world. Includes updates throughout to reflect changes to the airworthiness regulations of the two most influential ruling authorities—EASA and FAA Includes an update on remotely piloted air systems as well as space vehicles Provides guidelines to shape a comprehensive ‘certification map’ including comparisons, explanations, and backgrounds of institutions and processes Features a new chapter "Certificates of Airworthiness and Permits to Fly" that provides an overall description of the requirements governing the certificates of airworthiness
