NTSB Safety Recommendation — Aviation
Recommendation text
1. AMEND PARTS 23, 25, 27, AND 29 TO REQUIRE THE APPROPRIATELY COLORED CIRCLE AROUND EACH FILLER OPENING IN ADDITION TO THE PRESENTLY REQUIRED MINIMUM FUEL GRADE MARKINGS ON EACH AIRCRAFT. THE COLORED CIRCLE SHOULD CORRESPOND TO THE FUEL COLOR AND SHOULD BE PLACED ON A SLIGHTLY LARGER WHITE CIRCLE TO ASSURE EASE OF DIFFERENTIATION BETWEEN THE COLOR OF THE AIRCRAFT AND THE COLOR OF THE FUEL CIRCLE. 2. REQUIRE PAINTING OF EXISTING AIRCRAFT WITHIN A YEAR AFTER THE DATE OF PUBLICATION OF THE AMENDMENTS TO PART 23, 25,27, AND 29. 3. ADD ANOTHER PARAGRAPH TO THE "MARKINGS" SECTION OF ADVISORY CIRCULAR 20-43A SUGGESTING THAT REFUELING NOZZLES BE MARKED WITH THE PRESCRIBED COLOR-CODE.
In plain language (FlightFinder summary)
The FAA is asked to update aviation regulations so that fuel filler openings are marked with colored circles that match the specific type of fuel used in the aircraft. These markings must be placed on a white background to ensure they stand out clearly against the plane's exterior color. The recommendation also urges the immediate repainting of existing planes and suggests labeling refueling nozzles with corresponding colors to help prevent fueling errors.
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.
