NTSB Safety Recommendation — Aviation
Recommendation text
HOWEVER, IN VIEW OF THE POTENTIALLY SERIOUS CONSEQUENCES, THE BOARD IS CONCERNED ABOUT THE INABILITY OF PRESENT TURBINE ENGINE INSTALLATIONS TO PROTECT AIRFRAME STRUCTURE AND SYSTEM COMPONENTS ADEQUATELY FROM DAMAGE CAUSED BY TURBINE DISK FAILURE. IT URGES MANUFACTURERS AND OPERATORS OF TURBINE-POWERED AIRCRAFT, IN COLLABORATION WITH THE FEDERAL AVIATION ADMINISTRATION AND THE NATIONAL AERONAUTICS AND SPACE ADMINISTRATION PROGRAMS, TO MAKE A CONCERTED EFFORT TO PRODUCE AN ACCEPTABLE AND EFFECTIVE ROTOR BURST PROTECTION SYSTEM.
In plain language (FlightFinder summary)
Manufacturers and operators of turbine-powered aircraft, working with the Federal Aviation Administration and the National Aeronautics and Space Administration programs, are urged to collaborate on developing an acceptable and effective rotor burst protection system. The board is concerned that current turbine engine installations cannot adequately protect airframe structure and system components from damage caused by turbine disk failure, which could have serious consequences.
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.
