NTSB Safety Recommendation — Aviation
Recommendation text
TO THE FEDERAL AVIATION ADMINISTRATION: During the bird-ingestion rulemaking database (BRDB) working group‘s reevaluation of the current engine bird-ingestion certification regulations, specifically reevaluate the 14 Code of Federal Regulations (CFR) 33.76(d) large flocking bird certification test standards to determine whether they should 1) apply to engines with an inlet area of less than 3,875 square inches and 2) include a requirement for engine core ingestion. If the BRDB working group‘s reevaluation determines that such requirements are needed, incorporate them into 14 CFR 33.76(d) and require that newly certificated engines be designed and tested to these requirements.
In plain language (FlightFinder summary)
The Federal Aviation Administration is asked to have the Bird-Ingestion Rulemaking Database working group reevaluate the current engine bird-ingestion certification test standards for large flocking birds under 14 CFR 33.76(d). The reevaluation should consider whether these standards should apply to engines with an inlet area smaller than 3,875 square inches and include a requirement for engine core ingestion. If the working group determines such changes are needed, the FAA should incorporate them into the regulation and require that newly certificated engines be designed and tested to these updated standards.
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.
