NTSB Safety Recommendation — Aviation
Recommendation text
CONDUCT TESTS OF THE FUEL SYSTEM INSTALLED IN THE GRUMMAN AMERICAN AA-1B AIRPLANE TO ASCERTAIN THE AMOUNT OF USABLE FUEL UNDER THE MOST ADVERSE FUEL FEED CONDITIONS, INCLUDING THE EFFECTS OF TURBULENCE. IF THESE FLIGHT TESTS SO DICTATE, REQUIRE A FUEL SYSTEM DESIGN CHANGE IN ALL NEWLY MANUFACTURED GRUMMAN AMERICAN AA-1B AIRPLANES TO ASSURE 11 GALLONS OF USABLE FUEL PER TANK UNDER ALL OPERATIONAL CONDITIONS, OR ESTABLISH A NEW USABLE FUEL SUPPLY BASED ON THE ABOVE TESTS.
In plain language (FlightFinder summary)
The FAA is asked to test the fuel system of the Grumman American AA-1B airplane to determine how much usable fuel remains during difficult flight conditions, such as turbulence. Based on these results, the agency should either mandate a design modification for new aircraft to guarantee at least 11 gallons per tank or define a new standard for usable fuel supply that reflects the test findings.
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.
