2、y Analysis, Flight Data Recorders, Emergency Escape Decisions Description of Driving Event: A fatal accident involving the Ames/EFRF T-37B Jet Trainer (NASA 807) occurred east of California City, CA. at approximately 1:15 P.M. (PST) on November 8, 1982. NASA pilot Richard E. Gray was killed. The air

3、craft was totally destroyed by ground impact and fire. There were no other personnel injuries and no other property damage. Every attempt to establish probable cause has been unsuccessful. In the course of the research support flight, T-37B entered a spin resulting in an uncontrolled flight conditio

4、n, and the pilot delayed ejection until a successful ejection was no longer possible.Lesson(s) Learned: 1. Lack of knowledge/awareness of the effects of negative “G“ forces may have contributed to the crash.2. No supervision of flight, suggests oversight function could have identified need for prefl

5、ight training.3. Fact sheet material not clearly defined in function may have resulted in directive material being interpreted as advisory.4. Review of flight manual indicated possible lapse in updating material or in pilot training or both.5. Modifications made to aircraft may not have been reviewe

6、d/approved by safety, even though made for safety and flight reasons.6. Board review of accident was less effective because there was no flight data recording to evaluate.7. Flight managers must emphasize importance of adherence to emergency escape decision Provided by IHSNot for ResaleNo reproducti

Include information on incapacitation or disorienting effects of transitory “G“ forces on pilots, in all aircraft operations documentation.2. Maintain management ov

Institute adequate procedures to assure pilots flight manuals reflect current training.5. Develop procedures that require written approval for modification of research
