NTSB Safety Recommendation — Aviation
Recommendation text
TO THE EUROPEAN AVIATION SAFETY AGENCY: Expand your certification requirements for transport-category airplanes and aircraft engines to mandate that airplane and engine manufacturers work collaboratively to (1) analyze all critical fan blade impact locations for all engine operating conditions, the resulting fan blade fragmentation, and the effects of the fan-blade-out-generated loads on the nacelle structure and (2) develop a method to ensure that the analysis findings are fully accounted for in the design of the nacelle structure and its components.
In plain language (FlightFinder summary)
The European Aviation Safety Agency (EASA) is asked to expand its certification requirements for transport-category airplanes and aircraft engines. The new rules would mandate that airplane and engine manufacturers work together to analyze all critical fan blade impact locations and resulting fragmentation, as well as the effects of fan-blade-out loads on the nacelle structure. They must also develop a method to ensure these analysis findings are fully incorporated into the design of the nacelle structure and its components.
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.
