A-81-110
NTSB Safety Recommendation — Aviation
Recommendation text
THE NTSB RECOMMENDS THAT THE FEDERAL AVIATION ADMINISTRATION: CONDUCT AN ENGINEERING EVALUATION OF THE DC-9 SERIES -10 THROUGH -50 BRAKE HYDRAULIC ACCUMULATORS AND ANTISKID SYSTEMS TO DETERMINE IF THE BRAKE ANTISKID SYSTEMS CAN BE LEFT ON DURING HYDRAULICS-OUT LANDINGS. REVISE WHERE APPLICABLE THE HYDRAULICS-OUT LANDING PROCEDURES FOR THE DC-9 SERIES -10 THROUGH -50 AIRPLANES TO CORRESPOND WITH THOSE DEVELOPED FOR THE DC-9-80 WITHIN THE CAPABILITIES OF THE RESPECTIVE BRAKE HYDRAULIC ACCUMULATORS AND ANTISKID SYSTEMS.
In plain language (FlightFinder summary)
The NTSB asks the FAA to evaluate the brake hydraulic accumulators and antiskid systems on DC-9 series -10 through -50 aircraft to see if the antiskid systems can remain on during landings without hydraulics. Based on that evaluation, the FAA should update the hydraulics-out landing procedures for these models to align with those developed for the DC-9-80, as appropriate for each system's capabilities.
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.
