NTSB Safety Recommendation — Aviation
Recommendation text
THE NTSB RECOMMENDS THAT THE FEDERAL AVIATION ADMINISTRATION: ISSUE AN AIR CARRIER MAINTENANCE BULLETIN URGING OPERATORS AND MAINTENANCE PERSONNEL TO USE EXTREME CAUTION WITH ANY ELECTRICAL EQUIPMENT IN THE VICINITY OF TITANIUM ALLOY FAN BLADES TO MINIMIZE THE POSSIBILITY OF ARC BURN. THIS BULLETIN SHOULD ALSO DESCRIBE THE APPEARANCE OF ARC BURN IN TITANIUM AND POINT OUT THE NATURE OF DAMAGE CAUSED BY SUCH BURNS AND THE POSSIBLE CONSEQUENCES OF THIS DAMAGE.
In plain language (FlightFinder summary)
The NTSB asks the FAA to issue a maintenance bulletin urging operators and maintenance personnel to exercise extreme caution when using electrical equipment near titanium alloy fan blades to minimize the chance of arc burn. The bulletin should also describe the appearance of arc burn on titanium, the nature of the damage it causes, and the possible consequences of such damage.
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.
