NTSB Safety Recommendation — Aviation
Recommendation text
TO THE FEDERAL AVIATION ADMINISTRATION: Identify the deficiencies in Learjet’s system safety analyses, both for the original Learjet 60 design and for the modifications after the 2001 accident, that failed to properly address the thrust reverser system design flaws related to this accident, and require Learjet to perform a system safety assessment in accordance with 14 Code of Federal Regulations 25.1309 for all other systems that also rely on air-ground signal integrity and ensure that hazards resulting from a loss of signal integrity are appropriately mitigated to fully comply with this regulation.
In plain language (FlightFinder summary)
The Federal Aviation Administration is asked to identify deficiencies in Learjet's system safety analyses for the original Learjet 60 design and modifications after the 2001 accident, which failed to properly address thrust reverser design flaws. The FAA must also require Learjet to perform a system safety assessment per 14 Code of Federal Regulations 25.1309 for all other systems that rely on air-ground signal integrity, ensuring hazards from a loss of signal integrity are appropriately mitigated.
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.
