EAGLE Releases Part 1 Of ‘Clear The Air’ Series

The Eliminate Aviation Gasoline Lead Emissions (EAGLE) team has released Part 1 of a three-part series called “Clearing the Air: How Unleaded Aviation Fuel Is Gaining Approval.” Part 1 (attached below) is labeled “Understanding the STC process and why it matters to pilots and aircraft owners.” In a series of questions and answers, EAGLE attempts to clarify the differences between the Supplemental Type Certificate (STC) approval process as opposed to the Fleet Authorization protocol. Part 2 will further explore ASTM approvals through the Fleet Authorization process, followed by Part 3, which is tasked with explaining “the importance of industry consensus standards, such as those from ASTM International.”
