NTSB Safety Recommendation — Aviation
Recommendation text
THE NTSB RECOMMENDS THAT THE FEDERAL AVIATION ADMINISTRATION: ISSUE AN AIR CARRIER OPERATIONS BULLETIN TO PRINCIPAL OPERATIONS INSPECTORS REQUIRING THAT OPERATORS OF AIRPLANES EQUIPPED WITH THE FOLLOWING NAVIGATION RECEIVERS INCLUDE IN THEIR PILOT OPERATING MANUALS PROCEDURES FOR DETECTING MALFUNCTIONS THAT RESULT IN THE DISPLAY OF DISPARATE INFORMATION: COLLINS MODEL 51RV-1; COLLINS MODEL 51RV-4; WILCOX MODEL 806; KING MODEL KNR6030; AND SOME VERSIONS OF BENDIX MODEL RNA 26C. ALSO, NOTIFY FORMALLY FOREIGN AIRWORTHINESS AUTHORITIES ABOUT THE POTENTIAL FAILURE MODES IN SUCH EQUIPMENT.
In plain language (FlightFinder summary)
The NTSB asks the FAA to issue an air carrier operations bulletin requiring operators of airplanes with certain navigation receivers (Collins 51RV-1, Collins 51RV-4, Wilcox 806, King KNR6030, and some Bendix RNA 26C versions) to add procedures in pilot manuals for detecting malfunctions that show conflicting information. The FAA must also formally notify foreign airworthiness authorities about the potential failure modes in this equipment.
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.
