NTSB Safety Recommendation — Aviation
Recommendation text
THE NTSB RECOMMENDS THAT THE FAA: ISSUE A FLIGHT STANDARDS INFORMATION BULLETIN REQUIRING PRINCIPAL OPERATIONS INSPECTORS TO EMPHASIZE --- 1) THE IMPORTANCE OF FLIGHT CREWS DEACTIVATING THE FAULTED FIRE DETECTION LOOP IF AN ENGINE OR AUXILIARY POWER UNIT (APU) FIRE WARNING CHANGES TO A LOOP FAULT AND 2) THE PROPER METHODS FOR IDENTIFYING A FAILED FIRE DETECTION LOOP --- TO ALL OPERATORS OF AIRBUS A300-600 AND A310 AIRPLANES THAT HAVE NOT BEEN MODIFIED TO AUTOMATICALLY ARM THE REMAINING LOOP FOR FIRE DETECTION IN THE EVENT OF A SINGLE FIRE DETECTION LOOP FAULT IN THE ENGINE OR APU.
In plain language (FlightFinder summary)
The FAA is asked to issue a Flight Standards Information Bulletin that requires Principal Operations Inspectors to stress two points to operators of Airbus A300-600 and A310 airplanes lacking a modification that automatically arms the remaining loop for fire detection after a single loop fault: (1) the need for flight crews to deactivate a faulted fire detection loop if an engine or APU fire warning changes to a loop fault, and (2) the proper ways to identify a failed fire detection loop.
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.
