Book Description
As part of the FAA/NASA Controlled Impact Demonstration (CID) with a four-engine jet transport, 22 experimental seats have been placed on the aircraft by the contractor for the FAA. Four additional experimental seats have been directly installed by NASA and the FAA. Also, an originally installed pilot seat was included in the overall series of 27 seat experiments. Of the 22 seats installed by the contractor, 13 have been modified for the intent of improving their structural crashworthiness. These include 12 triple-occupant passenger seats and one flight attendant seat. The modification process was supported by extensive testing and analysis. Initially, identical seats were subjected to both static and dynamic destructive tests. From these tests, much was learned about the failure modes of the seat structure and the loads at which they would occur. Using these data, a design effort (supported by NASTRAN finite element models of the seats) produced methods for improving the capability of the seat structure to sustain crash loads. Prototypes of the designs were fabricated and subjected to identical static and dynamic testing sequences. Where necessary, design improvements were made and retested. Modified experimental seats were then fabricated for installation on the test aircraft.

Book Description
An unflinching look at the unique challenges posed by complex technologies we cannot afford to let fail—and why the remarkable achievements of civil aviation can help us understand those challenges. Nuclear reactors, deep-sea drilling platforms, deterrence infrastructures—these are all complex and formidable technologies with the potential to fail catastrophically. In Rational Accidents, John Downer outlines a new perspective on technological failure, arguing that undetectable errors can lurk in even the most rigorous and “rational” assessments of these systems due to the inherent limits of engineering tests and models. Downer finds that it should be impossible, from an epistemological viewpoint, to achieve the near-perfect reliability that we require of our most safety-critical technologies. There is, however, one such technology that demonstrably appears to achieve these “impossible” reliabilities: jetliners. Downer looks closely at civil aviation and how it has reckoned with the problem of failure. He finds that the way we conceive of jetliner reliability hides the real practices by which it is achieved. And he shows us why those practices are much less transferrable across technological domains than we are led to believe. Fully understanding why jetliners don't crash, he concludes, should lead us to doubt the safety of other “ultra-reliable” technologies. A unique and sobering exploration of technological reliability from an STS perspective, Rational Accidents is essential reading for understanding why our most safety-critical technologies are even more dangerous than we believe.

Book Description
The black box is orange—and there are actually two of them. They house the cockpit voice recorder and the flight data recorder, instruments vital to airplane crash analyses. But accident investigators cannot rely on the black boxes alone. Beginning with the 1931 Fokker F-10A crash that killed legendary football coach Knute Rockne, this fascinating book provides a behind-the-scenes look at plane wreck investigations. Professor George Bibel shows how forensic experts, scientists, and engineers analyze factors like impact, debris, loading, fire patterns, metallurgy, fracture, crash testing, and human tolerances to determine why planes fall from the sky—and how the information gleaned from accident reconstruction is incorporated into aircraft design and operation to keep commercial aviation as safe as possible.

Book Description
This report traces the progress of developments in seat and restraint systems for passengers in all types of aircraft. Results of carefully directed studies from the 1940's through current times leading to today's state of the art are reported as are specifications and regulations which have been developed. An extensive bibliography provides the sources of reports necessary for a reader who wishes to make an in depth study of the technology.
