In case there was any confusion, the FAA has reiterated the terms of Section 770 in the 2024 Grant Assurance Legislation in a recent Q&A Statement. No 100LL fuel bans are allowed — at any airport —for any reason. The Q&A Summary reads, “Grant Assurance 40 prohibits airports from restricting 100LL availability until an alternative fuel meets the established criteria.” Since no alternative has been found, as of yet, airports must make this type of AvGas available.

And the FAA plans to enforce this ruling. While the FAA is hopeful that educating sponsors will encourage compliance, FAA personnel are authorized to visit various airports to ensure the rule is being upheld, to watch for any indications the supplies are deficient, or respond to any complaints about alleged violations of this rule.
