100LL Endangerment Finding Released
General aviation groups say they are committed to a safe transition to unleaded aviation fuel after the EPA’s long-awaited October endangerment finding on 100LL. Immediately following the announcement, the Eliminate Aviation Gasoline Lead Emissions group, made up of the heads of most GA associations, held a media briefing to stress that it will work to ensure that 100LL remains available to operators whose aircraft require it to fly safely until a thoroughly tested alternative is readily available to them. Lirio Liu, FAA executive director for certification, said the FAA will have a central role in the transition. “The EPA can find that a component causes harm,” she said. “The FAA will define the standards.”
Hartzell Sold To Equity Firm
Hartzell Aviation has been acquired by $8.9 billion private equity fund Arcline Investment Management. The company, which operates the century-plus-old propeller business along with engine accessory and subsystem manufacturer Hartzell Engine Tech, has had the same family owners for almost four decades. “Our family has been blessed to be the stewards of Hartzell Aviation for 37 years. As we look to the future, we believe Arcline fully embraces our core value—Built on Honor—and will bring the skills and resources to build on over a century of excellence and innovation,” said Jim Brown, president of Hartzell Aviation.
