NTSB Safety Recommendation — Aviation
Recommendation text
TO THE FEDERAL AVIATION ADMINISTRATION: Provide your certification engineers with written guidance and training to ensure that (1) assumptions, data sources, and analytical techniques are fully identified and justified in applicants’ safety assessments for designs incorporating new technology and (2) an appropriate level of conservatism is included in the analysis or design, consistent with the intent of Advisory Circular 25.1309 (Arsenal draft).
In plain language (FlightFinder summary)
The Federal Aviation Administration is asked to give its certification engineers written guidance and training. This should ensure that safety assessments for designs with new technology fully identify and justify assumptions, data sources, and analytical techniques, and that an appropriate level of conservatism is included, consistent with Advisory Circular 25.1309 (Arsenal draft).
This plain-language summary is written by FlightFinder to explain the recommendation above. It is not the official wording — the verbatim NTSB text is quoted above.
