Washington State legislators have tabled a bill that would ban the sale of leaded aviation fuel in the state by 2030. The bill was introduced in the House and has been referred to committee. It has a long way to go before it’s law but if it survives the process, the phased-in ban would begin […]

A coalition of seven major aviation groups has submitted its comments on the EPA’s endangerment finding on leaded aviation fuel and it’s asking the agency not to jump the gun on banning tetrethyl lead. “The coalition urges the EPA, in coordination with the FAA, to ensure that any final finding and follow-on regulatory actions align […]

The typical stock nosewheel shimmy dampener does a decent job of taming minor oscillations, but the nosewheel on older airplanes (and Cessna singles in particular) eventually needs some care. When all other components are healthy, that often means replacing the shimmy damper (this is occasionally called a dampener), and two popular aftermarket upgrades come from […]

Edge Performance of Notodden, Norway, has been around for little more than a decade, but their EFI and Rotax upgrades have quickly become popular, setting a high bar with race-quality components. I’ll be putting the EP912sti in the SR-1 race plane—not only does it have exceptional power to weight (important given the 661-pound weight limit for […]
