NTSB Safety Recommendation — Aviation
Recommendation text
THE NTSB RECOMMENDS THAT THE FEDERAL AVIATION ADMINISTRATION: EXPEDITE THE PUBLICATION OF GUIDANCE MATERIAL FOR ACCEPTABLE MEANS OF COMPLIANCE WITH 14 CFR 25.903(D)(1), WHICH INCLUDES COMPLIANCE DOCUMENTATION BY FAILURE MODE AND EFFECT ANALYSIS, PROVIDES FOR ROTOR FRAGMENT ENERGY LEVELS AND PATHS BASED ON CASES OF SEVERE IN-SERVICE DAMAGE, AND REFLECTS ADVANCES IN ANALYTICAL TECHNIQUES AND CONCEPTS WHICH HAVE TAKEN PLACE SINCE CERTIFICATION PROGRAMS OF THE EARLY 1970'S.
In plain language (FlightFinder summary)
The FAA is asked to speed up the release of guidance on how to comply with regulation 14 CFR 25.903(d)(1). This guidance must include a failure mode and effect analysis, consider rotor fragment energy and paths based on real severe damage cases, and incorporate analytical advancements since the early 1970s.
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.
